Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets.

See also Overview of Blood. Plasma is the liquid component of blood, in which the red blood cells, white blood cells, and platelets are suspended. It constitutes more than half of the blood's volume and consists mostly of water that contains dissolved salts electrolytes and proteins. The major protein in plasma is albumin.

Blood function and composition

Find GPs in Australia. The formed elements are so named because they are enclosed in a plasma membrane and have a definite structure and shape. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells. Leukocytes are further classified into two subcategories called granulocytes which consist of neutrophils, eosinophils and basophils; and agranulocytes which consist of lymphocytes and monocytes. The formed elements can be separated from plasma by centrifuge, where a blood sample is spun for a few minutes in a tube to separate its components according to their densities. This volume is known as the haematocrit. WBCs and platelets form a narrow cream-coloured coat known as the buffy coat immediately above the RBCs.

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. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix plasma , which makes the blood a fluid. If blood flow ceases, death will occur within minutes because of the effects of an unfavourable environment on highly susceptible cells.

Human Physiology pp Cite as. Blood is an opaque red fluid consisting of the pale yellow plasma called serum when the fibrinogen is removed and the cells suspended in it - the red corpuscles erythrocytes , the white corpuscles leukocytes and the platelets thrombocytes. Blood has an important role in clinical diagnosis, because it is easy to collect and there are many diseases in which the blood composition and properties of the components are characteristically altered.

The whole blood which is a mixture of cells, colloids and crystalloids can be separated into different blood components namely packed red blood cell PRBC concentrate, platelet concentrate, fresh frozen plasma and cryoprecipitate. Each blood component is used for a different indication; thus the component separation has maximized the utility of one whole blood unit. Different components need different storage conditions and temperature requirements for therapeutic efficacy. A variety of equipments to maintain suitable ambient conditions during storage and transportation are in vogue. The blood components being foreign to a patient may produce adverse effects that may range from mild allergic manifestations to fatal reactions.

The constancy of the composition of the blood is made possible by the circulation , which conveys blood through the organs that regulate the concentrations of its components.

Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum. Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. These cells deliver oxygen to the cells and remove carbon dioxide.

Blood is a combination of plasma and cells that circulate through the entire body. It is a specialized bodily fluid that supplies essential substances around the body, such as sugars, oxygen, and hormones. Hematologists work to identify and prevent blood and bone marrow diseases, as well as studying and treating the immune system, blood clotting, and the veins and arteries. In the United States U.

The albumin contained in plasma prevents the blood from losing too much water and consistency as it travels through the narrow, water-permeable blood vessels capillaries. Albumin transports various blood components and nutrients. The immunoglobulins also contained in plasma are antibodies that, along with white blood cells, play an important role in fighting against pathogens.
