Chapter 12 Terms

Question 1

A narrowing of the arteries caused by thickening of the arterial walls and a buildup of lipid (primarily cholesterol) deposits. Reduces blood flow through the vessel, choking off the vital supply of oxygen and nutrients to the tissues served by that vessel.

Question 16

An increase in the diameter of blood vessles, commonly of the arterioles. Blood flow through the vessle increases, and blood pressure decreases as a result of this.

Answer 16

Vasodilation

Question 17

A graphical record of the electrical activity of the brain.

Answer 17

ECG

Question 18

The rhythmic expansion of an artery created by the surge of blood pushed along the artery by each contraction of the ventricles of the heart. With each beat of the heart, the wave of expsion beings, moving along the arter at the rate of 6 to 9 meters per second.

Answer 18

Pulse

Question 19

Answer 19

Ventricular Systole

Question 20

The highest pressure in an artery during each heartbeat. The higher of the two numbers in a blood pressure reading. In a typical, healthy adult, is about 120 mm Hg.

Answer 20

Systolic Blood Pressure

Question 22

A heart valve located between the left atrium and ventricle. It is also called the mitral valve or the left atria-ventricular (AV) valve

Answer 22

Bicuspid (mitral)

Question 23

A decrease in the diameter of blood vessels, commonly of the arterils. Blood flow through the vessel is reduced, and blood pressure rises as a result of this.

Answer 23

Vasoconstriction

Question 38

The events associated with the flow of blood through the heart during a single heartbeat. It consists of systole (contraction) and diastole (relaxation) of the atria and then of the ventricles of the heart

Answer 38

Cardiac Cycle

Question 39

Heart sounds other than "lup dup" that are created by turbulent blood flow. Can indicate a heart problem, such as a malfunctioning valvue.

Question 45

x

Answer 45

Tricuspid

Question 46

Choking or strangling chest pain, usually experienced in the center of the chest or slightly to the left, that is caused by a temporary insufficiency of blood flow to the heart. It begins during physical exertion or emotional stress, when the demands on the heart are increased and the blood flow to the heart muscle can no longer meet the needs.

Answer 50

Endocardium

Question 51

One of the two lower chambers of the heart that receive blood from the atria. Function as the main pumps of the heart. The right one pumps blood to the lungs. The left one pumps blood to body tissue.

Answer 51

Ventricles

Question 53

The body's main artery that conducts blood from the left ventricle toward the cells of the body. The aorta arches over the top of the heart and gives rise to the smaller arteries that feed the capillary beds of the body tissues.

Answer 53

Aorta

The lowest blood pressure in an artery during the relaxation of the heart. In a typical, healthy adult, the diastolic pressure is about 88 mm Hg.

Answer 54
