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

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.

A. Generating and transmitting impulses is the primary function of nervous tissue, not connective tissue. Nervous tissue is responsible for carrying signals throughout the body.

B. Covering and lining body surfaces is the function of epithelial tissue, which forms the skin and the lining of organs, not connective tissue.

C. Contracting and bringing about movement is the function of muscle tissue, not connective tissue. Muscle tissue is responsible for contraction and body movement.

D. Connective tissue's main function is to bind other tissues together and provide structural support. It includes tissues such as bone, blood, cartilage, and tendons, all of which help support, protect, and connect other tissues and organs.
