Inside the human body, blood does not coagulate due to the presence of_____________.

Correct option is C

The correct answer is (c) heparin.
● Heparin is produced by the liver and acts as a natural anticoagulant in the bloodstream. ● It works by inhibiting the action of thrombin, an enzyme essential for clot formation. ● Heparin is also used medically to prevent and treat blood clots, particularly in surgeries and other medical procedures. ● Without heparin, blood could potentially clot within blood vessels, leading to serious health complications. ● The liver and immune cells like basophils and mast cells contribute to the production and release of heparin. ● Heparin's anticoagulant property plays a crucial role in managing cardiovascular health and preventing thrombosis.
Information Booster:
· (a) fibrin: Fibrin is a protein that forms the mesh of a blood clot and plays a role in the coagulation process, not in preventing it.
· (b) haemoglobin: Hemoglobin is the protein responsible for oxygen transport in red blood cells and is not involved in blood coagulation.
· (c) heparin: The correct answer; it prevents blood from coagulating within the blood vessels.
· (d) thromboplastin: Thromboplastin is a protein that initiates the blood clotting process by converting prothrombin to thrombin, promoting coagulation.
