Practice Questions

Eosinophils are associated with allergic reactions. They constitute 2-3% of the total number of white blood cells. They resist infections. They also have anti-parasitic and bactericidal activity.

Basophils are a type of white blood cell or leukocyte. They constitute 0.5-1% of the total number of white blood cells. They participate in inflammatory reactions and secrete histamine, serotonin and heparin.

Monocytes and neutrophils are phagocytic white blood cells or leukocytes. These cells engulf and destroy foreign particles and various pathogenic organisms by the process of phagocytosis.

Out of all the different types of leukocytes present in blood, neutrophils are the most abundant in blood. They constitute 60-65% of the total number of white blood cells. They are phagocytic cells.

Plasma, which is an element of blood, constitutes 55% of it. Plasma is straw colored and a viscous fluid. 6-8% of plasma is made up of proteins while 90-92 per cent of plasma is made up of water.

Plasma, which is an element of blood, constitutes 55% of it. The rest 45% consists of the formed elements-the RBCs, the WBCs and the blood platelets. Plasma is straw colored and a viscous fluid.

Platelets are formed from the megakaryocyes. Thus, essentially, they are broken parts of a cell and thus must be removed eventually to avoid any problems to the body. Thus, within 8 – 12 days, the liver removes them from blood circulation.

The liver is responsible for detoxifying the body. Just like kidney filters blood and removes all the waste, the liver detoxifies the blood and ensures that the dead and dying cells are destroyed and removed.

When an RBC is produced in the bone marrow of the long bones, it is round in shape. It has a nucleus and a mitochondira. However, once the RBC matures, it looses its nucleus and mitochondira. Thus, the RBC are unable to reproduce by cell division or produce energy for themselves. Since the nucleus is usually the biggest organelle, the loss of nucleus makes the RBC become biconcave.

Kupffer cells is another name for megakaryocytes. These are Monocytic Agranulocytes, i.e. agranular WBCs having one large nucleus. They leave the Blood Vessels and can enlarge almost 30 times their size. The megakaryocytes of the brain are called mircoglial cells, lungs are alveolar macrophages, liver is Kupffer cells and for lymph nodes, spleen and bone marrow, they are sinuslining macrophages.

Basophils form 0.5% of all WBCs and neutrophil constitute 2% of WBCs. Basophils go to the site of injury and cause inflammation. The presence of this inflammation brings in eosinophils which surround the area and attack the source of the problem.

The main function of leukocytes, also known as white blood cells, is initiating the immune response. 
They protect the body against infectious diseases and foreign invaders.
White blood cells are a part of your immune system that protects your body from infection. 
These cells circulate through your bloodstream and tissues to respond to injury or illness by attacking any unknown organisms that enter your body.

The herb native to India and traditionally used to treat blood pressure is Sarpagandha, also known as Indian snakeroot

Blood is a type of connective tissue with a fluid matrix called plasma.

A universal donor is someone with the blood type O negative.
Blood Types: Human blood is classified into different types based on the presence or absence of certain antigens (proteins) on the surface of red blood cells. The main blood types are A, B, AB, and O.
Rh Factor: Another important factor is the Rh factor, which can be either positive (+) or negative (-).
