Exam 11: The Cardiovascular System

Match the following: -Heart chamber that contains the sinoatrial node

The walls of the ________ are substantially thicker because that chamber acts as the more powerful systemic pump of the heart.

Pulmonary circulation involves blood flow to and from the heart and the ________.

The single vessel that drains blood from the digestive tract organs to the liver is the ________.

What does each femoral vein become as it enters the pelvis?

Trace the path of a drop of blood, starting at the right atrium and returning to the right atrium, through the pulmonary and systemic circuits of the cardiovascular system. Identify the chambers, valves, and vessels (except specific systemic blood vessels that are not directly associated with the heart), and indicate whether the blood is oxygenated or deoxygenated in each area.

Exchanges between blood and tissue cells occur in capillary beds.

Sustained elevated arterial blood pressure above 140/90 mm Hg is a condition known as ________.

Which type of vessel is constructed only from tunica intima?

Match the following: -These vessels carry blood away from the heart

From innermost to outermost, the three layers of a vessel, with the exception of capillaries, are the tunica intima, tunica media, and tunica externa.

An incompetent aortic semilunar valve would allow blood to backflow from the ________.

Match the following: -The bicuspid (mitral) valve is situated between the left atrium and this chamber

The three branches of the aortic arch are the brachiocephalic trunk, left common carotid artery, and the left subclavian artery.

All four heart valves are briefly closed as pressure begins to rise in the ventricles, a phase known as ________.

Which term means heart contraction?

Match the following: -Due to low pressure in these vessels, skeletal muscle activity aids the return of blood by milking it along in these vessels toward the heart

Which of the following blood vessels is a direct branch of the ascending aorta?

The mitral valve is normally closed ________.

The tricuspid valve is located between the ________.
