Which best describes the blood flow in an artery apex?

Which best describes the blood flow in an artery apex?

Answer: It moves away from the heart.

What do we call the largest artery in our body?

aorta
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.

What has the greatest effect on blood flow?

Which of the following has the greatest effect on blood flow? You correctly answered: blood vessel radius.

Which is of the following best describes an artery?

A Arteries contain valves. B Arteries carry oxygenated blood. C Arteries carry blood away from capillaries. D Arteries carry blood away from the heart. E Arteries have thin walls compared with veins. Which of the following best describes an artery?

How is venous flow related to arterial flow?

Coronary venous flow is out of phase with coronary arterial flow. Venous flow is dominant in systole and is almost absent during the whole of diastole. The out-of-phase waveforms of arterial and venous flow demonstrate that intramural coronary blood volume is changing during each heartbeat.

Where does blood flow in the pulmonary artery?

Arise from the aorta or intercostal arteries and form a plexus in the peribronchial space. Small penetrating arteries then form a submucosal plexus and supply nutrition and oxygen to the airway support structures including the pulmonary artery vessels (vaso vasorum) but play no role in gas exchange.

What causes the flow of blood in the heart?

JOS A.E. SPAAN, MARIA SIEBES, in Heart Physiology and Pathophysiology (Fourth Edition), 2001 Coronary arterial blood flow is phasic, which is caused by the aortic pressure wave and compression of the intramural coronary vessels by contraction of the cardiac muscle.

Where does blood flow in the cardiovascular system?

This is the key function of the cardiovascular system: how well your heart, lungs, and organs consume, transport, and use oxygen throughout physical activity (which includes when you are at rest). The blood first enters the right atrium. It then flows through the tricuspid valve into the right ventricle.

Which is the only artery that carries oxygen-poor blood?

This artery is unique: It is the only artery in the human body that carries oxygen-poor blood. 1  The pulmonic artery carries blood to the lungs where it “picks up” oxygen and then leaves the lungs to return to the heart through the pulmonic vein. The blood enters the left atrium, then descends through the mitral valve into the left ventricle.

What is the relation between blood pressure and blood flow?

Blood flow is the movement of blood through a vessel, tissue, or organ. The slowing or blocking of blood flow is called resistance. Blood pressure is the force that blood exerts upon the walls of the blood vessels or chambers of the heart.

What kind of blood leaves the lungs and returns to the heart?

The pulmonic artery carries blood to the lungs where it “picks up” oxygen, and leaves the lungs and returns to the heart through the pulmonic vein. The blood enters the left atrium, then descends through the mitral valve into the left ventricle.
