The component of blood that prevents its clotting inside intact blood vessels is

A $antibody$
B $heparin$
C $thrombin$
D $haemoglobin$

Solution & Step-by-step Explanation

Heparin is a naturally occurring anticoagulant produced by basophils and mast cells in the human body. It circulates in the bloodstream to inhibit clotting factors (like thrombin), ensuring blood flows smoothly through intact blood vessels without forming dangerous internal blockages. Conversely, thrombin actively promotes clotting when a blood vessel is injured.
