Production of the Formed Elements Anatomy and Physiology I

  1. The formed elements of blood all originate in the yellow bone marrow of long bones
  2. Platelets, or thrombocytes, are the smallest of the formed elementsand are actually fragments of large cells called megakary-ocytes, which are found in bone marrow. (This is why the term formed elements is used instead of blood cells to describe erythro-cytes, leukocytes, and platelets.
  3. All of the formed elements of blood originate from this specific type of cell. Hemopoiesis begins when the hematopoietic stem cell is exposed to appropriate chemical stimuli collectively called hemopoietic growth factors, which prompt it to divide and differentiate

Al formed elements arise from stem cels of the red bone mar ow. Recal that stem cels undergo mitosis plus cytokinesis (celular division) to give rise to new daughter cels: One of these remains a stem cel and the other dierentiates into one of any numb er of diverse cel typ es. Stem cels may b e viewed as o c upyin The formed elements are cells and cell fragments suspended in the plasma. The three classes of formed elements are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets). Erythrocytes (red blood cells) Erythrocytes, or red blood cells, are the most numerous of the formed elements Production of formed elements of the blood in the red bone marrow Where does the majority of the final development and maturation of lymphocytes occur? This stag of growth occurs in the lymphoid organs Ex. lymph nodes, spleen, tonsils, thymus, and lymphatic nodule Blood is made up of both cellular and liquid components. If a sample of blood is spun in a centrifuge, the formed elements and fluid matrix of blood can be separated from each other. Blood consists of 45% red blood cells, less than 1% white blood cells and platelets, and 55% plasma

Since these living cells are suspended in plasma, blood is known as a fluid connective tissue and not just fluid. Provides oxygen to the cell Myeloid stem cells give rise to all other types of formed elements: Red blood cells, other types of white blood cells, and platelets 8 Red Blood Cell Counts Red Blood Cell Count = number of RBCs in a cubic millimeter (mm3) or microliter (μL) of blood

Blood cell formation, continuous process by which the cellular constituents of blood are replenished as needed. Blood cells originate not in the bloodstream itself but in specific blood-forming organs, notably the marrow of certain bones. In the human adult, the bone marrow produces all of the red blood cells All of the blood formed elements of the immune system originate in the bone marrow. 6. Describe how lymph nodes and spleen are involved in immune system-Lymph Nodes:Pea size:locate at Armpits:Auxiliary lymph nodes Groin area:inguinal Lymph nodes, one way filtering system with White blood cells inside.-Spleen: Red layer:Process dead Red Blood Cells Recall that blood is a connective tissue. Like all connective tissues, it is made up of cellular elements and an extracellular matrix. The cellular elements—referred to as the formed elements —include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called platelets

For example, the formation of red blood cells from hemocytoblast includes myeloid stem cell, proerythroblast, intermediates stages of accumulation of hemoglobin and enucleation and finally the red blood cells. Likewise, hemocytoblast can also from various white blood cells and platelets from different cell pathway The formed elements of the blood include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Of these, leukocytes are primarily involved in the immune response. All formed elements originate in the bone marrow as stem cells (HSCs) that differentiate through hematopoiesis

Lymphocytes are the only formed element of blood that arises from lymphoid stem cells. Although they form initially in the bone marrow, much of their subsequent development and reproduction occurs in the lymphatic tissues. Lymphocytes are the second most common type of leukocyte, accounting for about 20-30 percent of all leukocytes, and are. Define formed elements of the blood. formed elements of the blood synonyms, formed elements of the blood pronunciation, formed elements of the blood translation, English dictionary definition of formed elements of the blood. n. 1. A fundamental, essential, or irreducible constituent of a composite entity. From these names come, quite. Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss. carrying cells and antibodies that fight infection The most numerous among the formed elements of the blood are the erythrocytes, which contain hemoglobin. They transfer oxygen from the respiratory organs to the tissues and help transfer carbon dioxide in the opposite direction. They are responsible for the blood's red color Formed elements. The cells of the blood include the red blood cells and the white blood cells. In all vertebrates, except nearly all mammals, the red blood cells or corpuscles contain a nucleus and cytoplasm rich in hemoglobin

How are blood cells formed? The process of making blood cells is called hematopoiesis. Blood cells are made in the bone marrow. That's a spongy tissue located inside some bones. It contains young parent cells called stem cells. These blood-forming stem cells can grow into all 3 types of blood cells - red cells, white cells and platelets Blood Cell Lineage. The production of formed elements, or blood cells, is called hemopoiesis.Before birth, hemopoiesis occurs primarily in the liver and spleen, but some cells develop in the thymus, lymph nodes, and red bone marrow.After birth, most production is limited to red bone marrow in specific regions, but some white blood cells are produced in lymphoid tissue Blood Formation. Hemopoiesis ( hematopoiesis) is the process that produces the formed elements of the blood. Hemopoiesis takes place in the red bone marrow found in the epiphyses of long bones (for example, the humerus and femur), flat bones (ribs and cranial bones), vertebrae, and the pelvis. Within the red bone marrow, hemopoietic stem cells.

## NO Mothers Blood: For this very reason, it is unnecessary that a single drop of blood be given to a developing embryo in the womb of the mother. Such as the case according to science. The mother provides the fetus with the nutritive elements of the building of the little body, but all the blood which forms in the little body is formed in the. With the ossification of clavicle the3.Medulolymphatic period begins and gradually becomes the origin of all formed blood elements.The postnatal haemopoesis is concentrated in haematopoetic red.

Summary of Formed Elements Table 17.1 24. PLATELETS • Structure • Small cellular fragments; originate in bone marrow from giant cell megakaryocyte • Contain several clotting factors - calcium ions, ADP, serotonin • Function • Involved in stopping bleeding when a blood vessel is damaged; Process is called hemostasis 25 • Myeloid stem cells give rise to a ll other types of formed elements: Red blood cells, other types of white blood cells, and platelets The Origin of Blood Cells 8 Red blood cells (RBCs): • Also called erythrocytes • Biconcave disc shape • One-third hemoglobin: • Oxyhemoglobin (with O2) • Deoxyhemoglobin (without O2 White blood cells (WBCs) are the colorless formed elements of the blood. They differ from RBCs in that they are larger in size, but fewer in number (4,000-11,000 cells/cubic mm of blood). They have a nucleus, unlike RBCs, and exist in different shapes and sizes. In spite of variations in shape and size, WBCs play a very crucial role in our bodies

Formed Element Disorders of Blood Cells. Problems of red cells, white cells, and platelets are separated for discussion because one or the other is discovered to become one of the most abnormal throughout laboratory testing. However, due to the clonal nature of hematopoiesis, numerous disorders affect all of the formed components from the blood

Hematopoiesis is the process by which the body produces blood cells and blood plasma. It occurs in the bone marrow, spleen, liver, and other organs. It begins in the early stages of embryonic. Origin of formed elements Blood is composed of two components: � A fluid portion called plasma � A cellular portion known as the formed elements of the blood. The two components are approximately equal in volume. Plasma is about 90% water and 10% solutes. The principal solutes are the proteins: albumins, globulins and fibrinogen the red blood cells are destroyed faster than the bone marrow can replace them: hemolytic anemia: is an abnormal decrease in the number of platelets: thrombocytopenia: is consistenly elebated blood pressure of unknown origin: idiopathic hypertension: is marked by an absence of all formed blood elements: aplastic anemi Understand the relationship between blood group antigens and plasma antibodies in immunity .

Blood consists of several elements. The major components of blood include plasma, red blood cells, white blood cells, and platelets. Plasma: This major constituent of blood comprises about 55 percent of blood volume. It consists of water with several different substances dissolved within. Plasma contains salts, proteins, and blood cells Blood accounts for 7% of the human body weight, with an average density around 1060 kg/m 3, very close to pure water's density of 1000 kg/m 3. The average adult has a blood volume of roughly 5 litres (11 US pt) or 1.3 gallons, which is composed of plasma and formed elements.The formed elements are the two types of blood cell or corpuscle - the red blood cells, (erythrocytes) and white blood. Blood is composed of formed elements—erythrocytes, leukocytes, and cell fragments called platelets—and a fluid extracellular matrix called plasma. More than 90 percent of plasma is water. The remainder is mostly plasma proteins—mainly albumin, globulins, and fibrinogen—and other dissolved solutes such as glucose, lipids, electrolytes. When blood is spun out in a centrifuge, the formed elements, which are heavier, collect at the bottom.The red blood cells are heaviest at the bottom of the test tube. They form 45% of the blood. Then there is a tiny light colored layer of white blood cells and platelets called the buffy layer making up less than 1% of the blood..

Red blood cells are produced in a bone structure called red bone marrow, where most of the formed elements are made. Vertebrate red blood cells are anucleate, meaning that their red blood cells. Blood is composed of two parts: the fluid portion is called plasma, and the solid portion or formed elements (suspended in the fluid) consists of the blood cells (erythrocytes and leukocytes) and the platelets. Plasma accounts for about 55 per cent of the volume and the formed elements account for about 45 per cent. ( and table.


All types of formed elements develop from a single cell type -- stem cell (pleuripotential cells or hemocytoblasts). Seven different cell lines, each controlled by a specific growth factor , develop from the hemocytoblast. When a stem cell divides, one of the daughters remains a stem cell and the other becomes a precursor cell, either a. Testosterone is the primary sex hormone and anabolic steroid in males. In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone in both sexes is involved in health and well-being.

Thus, although all blood cells, even lymphocytes, are normally born in the bone marrow in adults, myeloid cells in the narrowest sense of the term can be distinguished from lymphoid cells, that is, lymphocytes, which come from common lymphoid progenitor cells that give rise to B cells and T cells Hemolysis & Fragility of RBC's Hemolysis: destruction of formed elements of blood/breakdown of RBC's to liberate hemoglobin Fragility: it is the susceptibility of RBC's to hemolysis 32 33. Process of hemolysis Normally plasma and RBC's are in equilibrium, but when this equilibrium is disturbed the cells get effected Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process. Blood is both a tissue and a fluid Formed Elements The remainder of the blood volume consists of the formed elements: • red blood cells • white blood cells • platelets In adults, these formed elements normally make up 40 percent to 45 percent of the total blood volume. This measure is called the hematocrit. Red Blood Cells Red Blood Cells are also called RBCs or Erythrocytes Moreover, there are three types of formed elements of blood cells and cell fragments: erythrocytes, leukocytes, and platelets. Each element of blood has a specific task in the process of maintaining the body's health and homeostasis. Furthermore, all cells and other elements develop from multipotent stem cells. We also call leukocytes as.

Cholesterol, triglycerides, and high-density lipoproteins are important constituents of the lipid fraction of the human body. Cholesterol is an unsaturated alcohol of the steroid family of compounds; it is essential for the normal function of all animal cells and is a fundamental element of their cell membranes. It is also a precursor of various critical substances such as adrenal and gonadal. A blood smear, also referred to as a peripheral smear for morphology, is an important test for evaluating blood-related problems, such as those in red blood cells, white blood cells, or platelets. It has a wide range of uses, including distinguishing viral infections from bacterial infections, evaluating anemia , looking for causes of jaundice.
