Which of the following is a component of the lymphatic system?

A. The ejaculatory ducts are formed by the union of the vas deferens and the seminal vesicles. Seminal fluid does not enter the ejaculatory ducts directly after leaving the epididymis.

B. The prostate gland contributes fluids to seminal fluid but is not the direct next location for the fluid after leaving the epididymis.

C. The seminal vesicle produces fluid that combines with sperm to form semen, but it is not the immediate next structure after the epididymis.

D. The vas deferens is the tube that transports sperm from the epididymis to the urethra. After leaving the epididymis, seminal fluid enters the vas deferens.

A. Vasodilation refers to the widening of blood vessels, which typically lowers blood pressure by decreasing the resistance within the vessels.

B. Increased cardiac output means the heart pumps more blood per minute, which raises blood pressure by increasing the volume of blood circulating through the arteries. This is the correct answer.

C. Decreased heart rate would typically lower blood pressure, as the heart is pumping less frequently, reducing the force exerted on the blood vessels.

D. Parasympathetic stimulation generally lowers blood pressure as it promotes relaxation and reduces the heart rate, which in turn reduces cardiac output.
