Question

all of the following are qualities of the uterus except: a one of its layers, the endometrium, is shed during menstruation. b monthly hormonal cycles lead to various changes, such as menstruation, although the exact cycle length depends on the person. c it is part of the pathway where sperm can fertilize an ovum. d it is a thin - walled organ that becomes larger during sexual arousal because it is engorged with blood.

Explanation:

The uterus is not a thin - walled organ that becomes larger during sexual arousal due to blood engorgement. That description is more applicable to the vagina. The endometrium is shed during menstruation (A is a quality of the uterus), hormonal cycles affect the uterus and lead to menstruation (B is a quality), and the uterus is part of the pathway for sperm - ovum fertilization as the fertilized ovum implants in the uterus (C is a quality).

Answer:

D. It is a thin - walled organ that becomes larger during sexual arousal because it is engorged with blood.
