What is the function of the thrombocytes?
A.
Defend against infection
B.
Transport respiratory gases.
C.
Form connective tissue.
D.
Play a role in blood clotting.
The correct answer is:
D. Play a role in blood clotting.
Explanation: Thrombocytes, also known as platelets, are small cell fragments in the blood that play a crucial role in the blood clotting process. When a blood vessel is injured, thrombocytes gather at the site of the injury and work to form a clot, preventing excessive bleeding.
- A. Defend against infection: This function is primarily carried out by white blood cells (leukocytes), not thrombocytes.
- B. Transport respiratory gases: This function is performed by red blood cells (erythrocytes), which carry oxygen and carbon dioxide.
- C. Form connective tissue: This function is not related to thrombocytes but rather to fibroblasts and other cells that produce the extracellular matrix of connective tissues.
