Which of the following secretes the hormone, relaxin, during the later phase of pregnancy?

Options

A. Corpus luteum
B. Foetus
C. Uterus
D. Graafian follicle

Answer

A

Explanation

The hormone relaxin is produced in the later phase of pregnancy. It helps in parturition as it increases the flexibility of the pubic symphysis and helps dilate the uterine cervix. Relaxin is produced first by the corpus luteum of the ovary and later by the placenta. Ruptured Graafian follicle is called corpus luteum, which has endocrine function.
• Foetus and Uterus do not produce relaxin
