Explain the Two Cardiovascular Pathways ?

What’s the major blood vessel that takes blood back to the heart? What’s the major blood vessel that takes blood to the tissues?

Can you describe how blood moves through all parts of the heart?

Which of the following is an inaccurate description of autonomic innervation of the cardiovascular system? A) Both sympathetic and parasympathetic neurons innervate the SA and AV nodes. B) Only sympathetic neurons provide significant innervation of the contractile cells of the heart. C) Only sympathetic neurons innervate smooth muscle in veins. D) Sympathetic activity increases cardiac output, whereas parasympathetic activity decreases cardiac output. E) Both sympathetic and parasympathetic neurons innervate smooth muscle in arterioles.

What is the role of the cardiovascular center in the feedback loop when blood volume and blood pressure fall? A) Control Center B) Effector C) Variable D) Receptor
