FORMED ELEMENTS OF BLOOD SKIN

FORMED ELEMENTS OF BLOOD SKIN

Excretion- Waste products from cellular metabolism are carried within the plasma and excreted via the kidneys, lungs and skin.Oxygen is carried to the body from the lungs and carbon dioxide back to the lungs for excretion. Transportation of Nutrients- Nutrients such as glucose, amino acids, liquids and vitamins are transported in the blood plasma from the digestive system to different body parts.Acid-base balance- Plasma proteins helps in acid-base balance through buffering action.Maintenance of osmotic pressure- The presence of plasma proteins such as Albumin which is vital for maintaining a balance of fluid, called oncotic pressure, in the blood (maintained at around 25 mmHg).Immune Defense- Plasma has Immunoglobulins (antibodies) that play a role in the bodyвЂ™s immunological defence process.Coagulation- Plasma contains fibrinogen and procoagulants such as thrombin and factor x.ДЇunctions of Blood Plasma Д«lood Plasma has various vital functions, In an adult, the reticuloendothelial cells in the liver are responsible for plasma production this process is aided by bone marrow and spleen. The albumin is formed first, followed by globulin and then other plasma proteins. In the embryonic stage blood plasma is formed from the mesenchymal cells. It is composed of 91% of water and 9% solids such as coagulants, plasma proteins, electrolytes and immunoglobulins. Д«lood Plasma is a light вЂ“ yellowish liquid. The total blood volume forms about 7 to 8В % of the total human weight in normal healthy adult.The other 45% comprises of a variety of different forms of cells.Plasma forms about 55% of the total blood volume.The adult human has from 4 to 5 litres of blood formed of cells and plasma circulating the body in vessels Blood is composed of plasma, platelets, leukocytes (White Blood Cells) and erythrocytes. Blood is critical in the homeostatic regulation of pH, temperature and various other internal conditions.

It also has important immunological functions.Blood is critical for the transportation of nutrients, hormones, gases and wastes around the body.Blood is a necessity for the preservation of human life.
