Philoid · Accepted Answer

a. Plasma without blood clotting factors is called serum.

Explanation: Serum is a clear fluid devoid of clotting factors made through centrifugation.

b. Neutrophils and monocytes are phagocytic cells.

Explanation:

Neutrophils are phagocytotic. Whenever an infection occurs these cells are the first ones to reach the site and engulf the microbes.

Monocytes are phogocytotic and are known as White Blood Cells(WBC’S).Whenever an infection occurs these cells get activated and start attacking the germs. These cells engulf cancer cells, damaged and dead cells.

c. Eosinophils are associated with allergic reactions.

Explanation: Eosinophils promote inflammation and generate symptoms related to allergy as in Asthma, Hay fever, Pollen allergies etc.

d. Calcium ions play a significant role in clotting.

Explanation: When the injured tissues and platelets release Thromboplastin, initiation of enzyme prothrombinase takes place. Prothrombin in the presence of Calcium ions converts plasma protein Prothrombin to Thrombin. Now, Thrombin converts fibrinogen to fibrin. This fibrin helps in formation of clot by aggregating platelets, blood cells and plasma.

e. One can determine the heart beat rate by counting the number of ORS complex in an ECG.
