What Is Plasma?

Blood is a mobile fluid which is a connective tissue and is derived from the mesoderm like cell any other connective tissue. Colour of blood is reddish and that flows inside the blood vessels by means of pumping activity of heart. An adult human contains almost 5 litres of blood to 5.5 litres of blood. Or it can be said that 30% to 35% of the total extracellular fluid or ECF is made up of blood. Where is the overall water content of the body is 78% for solids constitute 22% and the tissue is Peculiar in that neither these cells are formed in sea to know its matrix is derived from the cells. The pH of the blood is slightly alkaline whose value is 7.4 and it can be divided into two parts as 55% of the blood is made up of Plasma and 45% of the blood is made of formed elements.

Blood Plasma - Plasma is the liquid matrix of the blood which colour is pale yellow and it occupies 90% to 92% of the water. If blood is taken in a centrifugal to and then we go through the process of centrifugation then it can be shown the different components of the blood are sedimented according to their molecular weight in the test tube. 

As we all know that the molecular weight of the red blood corpuscles is highest so it is dissipated at the bottom level of the test tube then white blood cell is precipitated just above the RBC according to their molecular weight. When the major portion of the tube occupied by the plasma which comes above the RBC and WBC and consists of mainly the fluid or water portion of the body. As the remaining 8% to 10% of the plasma consists of the following components those are described below-

Proteins - Almost 70 types of proteins are present in the plasma and they can be categorised mainly into 3 category. Those are serum albumin serum globulin and fibrinogen. Elements are type of protein and constitute about 50% of the total proteins which produce 75% to 80% of colloidal osmotic pressure. This protein bind with plasma calcium and also bind with some fatty acid molecules. Globulins are the type of proteins and eat constitute about 16% of the total plasma proteins. Globulins can be of 3 times they are alpha beta and gamma globulins. Alpha globulin is involved in the transportation of thyroxine hormone and bilirubin pigment. Where is erythropoietin the hormone for execution of erythropoiesis is also an Alpha globulin protein. Function of Beta globulin is that they binds with vitamins A, D and K, cholesterol and ions. Immunoglobulins are produced by the gamma globulins and they are the major things in the formation of antibodies so they are major role we found in the body defence mechanism. Are the different proteins of the body are propadiene and lysozyme which we found in the tears and the Saliva that destroy the germs. Some other proteins that are also globulin in nature are found in our body are prothrombin thromboplastin and antihemophilic factors these are also responsible for blood clotting. Fibrinogen formed by fibrin during the blood coagulation where is blood proteins also help to retain water in blood and function as pH buffer. Deficiency of the protein causes Idi Maa where is some of the blood proteins like Alpha globulin albumin beta globulin fibrinogen prothrombin are produced in liver. But Gamma globulins developing plasma cells of lymphatic tissue.

Nutrients - After metabolism different nutrients from the food is released in the blood plasma and that is carried to the different cell or tissues of the body. These nutrients part of the blood is consist of glucose facts fatty acids amino acids and vitamins. Vitamins A, D, E, K are fat soluble where is the rest of the vitamins are water soluble. Nutrients are associated with the growth and development of the body and synthesis of different biomolecules where does vitamins have different important roles in different physiological activities. Nutrients are transported to region of utilisation and their normal value of the content of Nutrition are- glucose 80- 100 mg/ml before meals and 180 mg per 100 ml after 1 hr to 1.30 hr after meals. Threshold value of glucose is 150 mg. High value of glucose results as Diabetes mellitus. Kylo microns are the minute droplets of life of protein which contains 90% fat small amounts of proteins, cholesterol and phospholipid. Chylomicrons are carried from alimentary canal to area of utilisation via lymphatic and blood vascular system.

Cholesterol - Cholesterol is the fat of the blood only fat molecules of the blood which value ranges from 50 MG per 100 ml of Plasma and 180 mg per 100 ml of Plasma.

Anticoagulant - Anticoagulant are the different types of protein molecules which are associated with the reduction of the coagulation tendency within blood as a result of this anticoagulant blood are able to flow smoothly within the vessels without coagulate in any portion. Examples of anticoagulant are heparin which is a mucopolysaccharide and it is occurred in plasma produced by the basophil and muscles of the blood and its main function is to prevent coagulation of blood inside blood vessels.

Hormone - Hormones are the chemical messengers of the human body which are transported by blood from endocrine glands to the target tissues and their player they are different physiological activities on the different systems of the body. Secretion of hormones are maximum controlled by the pituitary gland buy secret in the regulating hormone. Different hormones of hydroxy associated with body basal metabolism adrenaline associated with the control of image emotions and expression different hormones controlling the sexual activity and the symptoms etc.

Excretory Product - As we all know that metabolism is a process which help to extract the nutrients from the food and release the energy from the food for the use of our body purpose it also produces different metabolic waste products that should be removed from our body unless it may cause harm. This excretory products include urea uric acid creatinine creating etc and urea is the most important waste product of the human body. Normal urea content of the blood is 17 mg to 30 MG per 100 ml blood and excess presence of Urea in the blood causes uremia.

Inorganic Substances - Blood plasma contain the inorganic questions of the blood dozer oxygen carbon dioxide etc gases, solids ions like sodium ion chloride ion magnesium and calcium iron manganese ion phosphate Ion bicarbonate iodide. About 0.9 percent off the plasma is called salt and sodium ion and chloride Ion concentration is 320 mg per 100 ml of plasma and 340 mg per 100 ml of Plasma.
