BLOOD

The study of blood is called Hematology.

A normal person has 5-6 liters of blood in his body.

7% of human body weight is blood.

The pH value of blood is 7.4.

Blood is a cyanotic tissue.

The nature of blood is less alkaline.

Blood consists of plasma, blood corpuscles, organic and inorganic elements.

Blood controls our body temperature.

Blood performs as Messenger functions, including the transport of hormones and the signaling of tissue damage.

Blood are Supplier of oxygen to tissues (bound to hemoglobin, which is carried in red cells) also Supplier of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (e.g., blood lipids))

Blood is circulated around the body through blood vessels by the pumping action of the heart.

The body temperature is 37 ℃.  98.6 ° F and 310 Kalvin.

Blood donation is done in the unit.  One unit contains 350 ml of blood.

The blood is kept in the blood bank at a temperature of 4.4 ℃.

While keeping the blood in the blood bank, 50 ml of sodium citrate is added to 1 unit of blood.  Sodium citrate prevents blood from freezing.

Blood in the blood bank can be preserved for a maximum of 42 days.

Hyperion protein performs the function of blocking the blood in our body.

It takes 3 to 8 minutes to form a blood clot.

blood perform as Removal of waste such as carbon dioxide, urea, and lactic acid.

blood perform as Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies.

blood perform as Coagulation, the response to a broken blood vessel, the conversion of blood from a liquid to a semisolid gel to stop bleeding.

Blood Donation Day is celebrated on 14 June.

Inside the blood is 55 percent plasma, 8 percent organic (carbohydrate, protein, fat) and inorganic (mineral content, vitamins) elements and the rest blood corpuscles.

Plasma is yellow colored liquid that contains 92 percent water.

There are 4 types of proteins found in plasma. - Albumin, Globulin, Prothrombin and Fibrinogen.

There are three types of blood corpuscles.  Red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes).

Platelets are important in the clotting of blood.

Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells.
