Atherosclerosis is a major cause of heart diseases. Chapter menu Resources Copyright © by Holt, Rinehart and Winston. All rights reserved. Chapter 6 Section 1 The Cardiovascular System Cardiovascular Problems, continued • High Blood Pressure Hypertension is abnormally high blood pressure. The higher the blood pressure, the greater the risk of a heart attack, heart failure, kidney disease, and stroke. • Heart Attacks and Heart Failure A heart attack happens when heart muscle cells die and part of the heart muscle is damaged. Heart failure happens when the heart cannot pump enough blood to meet the body’s needs. Chapter menu Resources Copyright © by Holt, Rinehart and Winston. All rights reserved.

Chapter 6 Section 4 The Respiratory System Breathing • Breathing is done by the diaphragm and rib muscles. The diaphragm is a dome-shaped muscle beneath the lungs. Breathing and Cellular Respiration • In cellular respiration, oxygen is used by cells to release energy stored in molecules of glucose. When you inhale, you take in oxygen, which diffuses into red blood cells and is carried to tissue cells. Chapter menu Resources Copyright © by Holt, Rinehart and Winston. All rights reserved.
