Which of the following provides lubrication of the vagina during sexual excitement?

A. Angiotensin does not inhibit thirst; in fact, it stimulates thirst as part of its role in increasing blood pressure and fluid retention.

B. Angiotensin, specifically angiotensin II, stimulates vasoconstriction, which increases blood pressure by narrowing blood vessels. This is one of its primary actions in regulating blood volume and pressure.

C. Angiotensin actually promotes the retention of salt and water in the kidneys to increase blood volume and pressure, rather than stimulating their elimination.

D. Angiotensin does not inhibit antidiuretic hormone (ADH) release; it actually stimulates the release of ADH, which promotes water retention by the kidneys to increase blood volume.

A. Flexion refers to a bending movement that decreases the angle between two body parts, such as bending the knee or elbow, but it does not involve lateral movement away from the body's midline.

B. Adduction is the movement of a body part toward the midline of the body, opposite of what the question describes.

C. Extension refers to a straightening movement that increases the angle between two body parts, such as straightening the arm or leg, but again does not involve lateral movement.

D. Abduction is the correct term for moving a limb or body part away from the midline of the body. In this case, it refers to the lateral movement of the leg away from the body's midline.
