Document Summary

Four chambers (2 atria and 2 ventricles) that receive blue (deoxygenated) blood from the body and pump out red (oxygenated) blood back to it. The atria receive blood coming back to the heart. The ventricle pump the blood out of the heart. Blood vessels, which include a network of arteries and veins that carry blood throughout the body: arteries transport blood from the heart to the body tissues, veins carry blood back to the heart. Cardiac output = heart rate x stroke volume. Heart attack: blood supply to the heart is reduced; heart is damaged. Cardiac arrest: heart stops beating, preventing blood to get to organs. Stroke: heart stops long enough to cut off blood supply to brain. Brain cells die within minutes of a stroke. Tiny hairs in the nasal passageway called cilia filter the breathed air. The pharynx i the meeting point of the nose and throat. It splits into the esophagus (for food) and the trachea (windpipe)
