Question

The major function of corpus luteum is

• A. Excretory
• B. Digestive
• C. Nervous
• D. Endocrine

Answer 1

Answer: (D)

Endocrine

A. Excretory function is the elimination of toxic substances from the body.

B. Digestive function is the secretion of digestive enzymes and juices in the alimentary ducts.

C. Nervous function is the transmission of impulse across nerve cells.

D. Endocrine function is the secretion of hormones directly into blood stream.

Corpus luteum is formed in ovary after ovulation and degenerates in absence of pregnancy but if pregnancy occurs it persists and secretes progesterone and oestrogen hormones. It acts as an endocrine gland because it is a ductless gland and secretes hormones directly into blood stream.

So, the correct answer is 'Endocrine'.
