Exam 15: The Circulation of the Blood

The first blood vessel of pulmonary circulation is the

Veins serve as the blood reservoirs for the body.

What is phlebitis and why is the formation of a thrombus more likely in a vein than in an artery?

As stroke volume goes up,blood pressure goes up.

The single umbilical vein carries metabolic waste and carbon dioxide from the fetus to the mother.

A person who has suffered a severe heart attack would be most at risk of cardiogenic shock.

Which of the following is a condition in which blood pools in the veins because the valves have become incompetent?

Explain the blood pressure gradient in the body.Why must the gradient be as it is?

Many medications are inactivated by the enzymes in the liver.These medications are almost always given intravenously or by injection into a muscle,not orally.Explain why these medications must be given this way.

Describe pulmonary circulation.What is the difference between the blood in the pulmonary arteries and veins compared with the blood in the systemic arteries and veins?

Blood that drains into the liver from the hepatic portal system has already been through one set of capillaries.

Which of the following is the smooth inner layer of the blood vessels?

The tunica media in the arteries helps maintain blood pressure and blood distribution in the body.

A person who has suffered a serious loss of blood would be most at risk for cardiogenic shock.

Blood pressure is highest in the

Arteries and arterioles both distribute blood from the heart to the capillaries.

Describe the ductus venosus,the ductus arteriosus,and the foramen ovale.How do these structures make fetal circulation more efficient?

The foramen ovale shunts blood from the right ventricle into the left ventricle.

What is an aneurysm?

An increase in heart rate always increases blood pressure.
