Which Component of Blood Plasma Plays a Role in Blood

Question

Which component of blood plasma plays a role in blood clotting and the regulation of fluid volume?
A) Platelets
B) Proteins
C) Red blood cells
D) Electrolytes

Accepted Answer

Proteins in blood plasma, such as fibrinogen and thrombin, play a crucial role in blood clotting. Additionally, proteins such as albumin and globulin help regulate fluid volume and maintain osmotic pressure within the blood vessels. Platelets play a role in blood clotting but are not a component of blood plasma. Red blood cells carry oxygen and electrolytes help maintain cellular function and balance, but neither play a direct role in blood clotting or fluid regulation.
