Describe the two types of cycles that occur in female mammals (menstrual vs. estrous).

Answer 1

Menstrual and Estrous cycles are two types of cycles that occur in female mammals. 

The menstrual cycle is found in humans and primate mammals (baboons or monkeys). It refers to the reproductive cycle. During a menstrual cycle, the endometrium is shed.

On the other hand, the Estrous cycle is the reproductive cycle of females of non-primate mammals, for example, sheep, goats, horses, bears, etc. During estrous the endometrium is reabsorbed by the body.

The endometrium is the lining of the uterus.
