Which of the following functions is associated with angiotensin?

A. The stomach plays a key role in digestion by breaking down food mechanically and chemically but does not play a significant role in nutrient absorption.

B. The large intestine is primarily involved in water and electrolyte absorption, as well as the formation of feces. It does not significantly contribute to nutrient absorption.

C. While some digestion begins in the mouth, particularly with enzymes in saliva, nutrient absorption does not occur there.

D. The small intestine is the primary site of nutrient absorption in the digestive system. Its walls are lined with villi and microvilli that increase surface area for the absorption of nutrients such as carbohydrates, proteins, fats, vitamins, and minerals.

A. The ovaries are responsible for producing hormones such as estrogen and progesterone but do not directly produce lubrication during sexual excitement.
B. The cervix produces mucus that changes in consistency throughout the menstrual cycle but does not play a significant role in lubrication during sexual activity.
C. Skene's glands, located near the urethra, secrete fluid that is often compared to prostate fluid in males, but they do not play the primary role in vaginal lubrication during sexual excitement.
D. Bartholin's glands, located near the vaginal opening, secrete mucus that provides lubrication during sexual excitement, helping to reduce friction and enhance comfort during intercourse.
