Blood cells: Blood (histological slide) In this

Blood (histological slide) In this article we will describe the different types of blood cells. Blood is specialized fluid connective tissue. It travels through the circulatory system transporting gases, nutrients, wastes, and other macromolecules throughout the body. The main gases traveling in the blood are oxygen and carbon dioxide. Circulating macromolecules include hormones, nutrients, plasma proteins, and some humoral components of the immune system. Blood also acts as a buffer to ... 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. Blood, “The River of Life” as it supports life. It contains the nutrients and oxygen that support living organisms. The cells in the blood are generally synthesized in the bone marrow by a process called haematopoiesis. Blood contains three types of blood cells, namely Erythrocytes or RBC, Leukocytes or WBC and Platelets. Almost half of the total blood is composed of blood cells. These cells are developed from the bone marrow. WBC can be sub-classified into 2 other groups, Granulocytes ... Learn about the three types of blood cells: red, white and platelets, and their roles in transport, immunity and clotting. Find out the characteristics, life spans and functions of each cell type, and see examples of microscopic images.
