Overview of blood and blood components The production and development of new cells in the bone marrow is a process called hematopoiesis. Blood cells formed in the bone marrow start out as a stem cell. A stem cell (or hematopoietic stem cell) is the initial phase of all blood cells.As the stem cell matures, several distinct cells evolve, such as the red blood cells, white blood cells, and platelets. Immature blood cells are also called blasts.he production and development of new cells in the bone marrow is a process called hematopoiesis.

Blood These blood cells (which are also called corpuscles or  formed elements ) consist of erythrocytes (red blood cells, RBCs), leukocytes (white blood cells), and thrombocytes (platelets). By volume, the red blood cells constitute about 45% of whole blood, the plasma about 54.3%, and white cells about 0.7%.he blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets. The most abundant cells in vertebrate blood are red blood cells.

White blood cell All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system. All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets.

Define formed elements and list their three major categories. Which is the least numerous? Which is the most? Answers. Best Answer: The formed elements of the blood are all the cellular components in the blood. The three major categories correspond to the maturational lineages followed by the immature, pluripotent stem cells in the bone marrow-the erythroid, myeloid and lymphoid lineages. The least numerous formed element is probably the white blood cell called the basophil. There are very few of them seen in a peripheral blood draw. The most numerous are probably the red blood cells or erythrocytes. The buffy coat consists of all the white blood cells in a centrifuged blood sample, such as one has in a hematocrit tube.

"What is the definition of ""FORMED ELEMENTS OF BLOOD?"" ?" Report Abuse. The formed elements of blood are blood cells, which include erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets). Thrombocytes are derived from special bone marrow cells, but in blood, they are present as cell fragments. Each microliter of blood contains 4 to 6 million erythrocytes, 4,500 to 10,000 leukocytes, and 150,000 to 400,000 thrombocytes.

What is blood composed of? Like the red and white blood cells, platelets are produced in bone marrow from stem cells. Plasma. Plasma is the relatively clear, yellow tinted water (92+%), sugar, fat, protein and salt solution which carries the red cells, white cells, and platelets. Normally, 55% of our blood's volume is made up of plasma.eukocytes are not limited to blood. They occur elsewhere in the body as well, most notably in the spleen, liver, and lymph glands. Most are produced in our bone marrow from the same kind of stem cells that produce red blood cells. Others are produced in the thymus gland, which is at the base of the neck.

119 18.2 Production of the Formed Elements All formed elements arise from stem cells of the red bone marrow. Recall that stem cells undergo mitosis plus cytokinesis (cellular division) to give rise to new daughter cells: One of these remains a stem cell and the other differentiates into one of any number of diverse cell types.
