The movement of the electrical impulse in the heart can be used to detect abnormal activity or disease.
The smallest branches of arteries are called arterioles.
Capillaries have thin walls containing only one layer of cells.
allow oxygen and nutrients to pass through to body cells. Capillaries
blood proteins necessary for the clotting of blood. Fibrinogen and prothrombin
carries both oxygen and carbon dioxide. Hemoglobin
a result of injury to or destruction of the bone marrow Aplastic anemia
a foreign substance circulating in the bloodstream. embolus
A common symptom of a myocardial infarction is a severe, crushing pain that radiates to the arm, neck, and jaw.
a chronic, inherited anemia that occurs almost exclusively among African Americans. Sickle cell anemia
abnormal heart rhythms that can be mild to life threatening. Arrhythmias are

If not treated, it can cause permanent damage to the heart, blood vessels, and kidneys. hypertension
The muscle layer of the heart is the myocardium
The chamber of the heart that receives deoxygenated blood as it returns from body cells right atrium
The chamber of the heart that receives oxygenated blood as it returns from the lungs is the left atrium
The valve between the right atrium and right ventricle that prevents blood from flowing back into the right atrium is the tricuspid valve
The valve between the left atrium and left ventricle that prevents blood from flowing back into the left atrium is the mitral valve
The blood vessels that carry blood away from the heart are the arteries
blood vessels that contain valves to prevent blood from flowing in a backward direction are the veins

The blood cells that contain hemoglobin are the erythrocytes
The number of erythrocytes in one cubic millimeter of blood is 4.5 to 6 million
The bright red color of blood indicates hemoglobin-carrying oxygen
The blood cells that fight infection are the leukocytes
The blood cells that fight infection are the leukocytes
A normal thrombocyte count per cubic millimeter of blood is 250,000 to 400,000
lack a nucleus, vary in shape and size, required for the clotting process Thrombocytes
An inherited disease that occurs almost exclusively in males and in which the blood is unable to clot hemophilia
An inflammation of a vein with the formation of a clot is thrombophlebitis
The leukocytes that provide immunity for the body by developing antibodies and protect against the formation of cancer cells are lymphocytes
Dilated, swollen veins that have lost elasticity and cause stasis, or decreased blood flow, are called varicose
race, smoking and obesity increases the incidence of hypertension
things that blood transports through the body oxygen, carbon dioxide, nutrients (vitamins, carbohydrates, proteins, mineral salts or electrolytes), metabolic and waste products, heat, hormones
occurs when fatty plaques are deposited on the walls of arteries atherosclerosis
treatments used to control hypertension anti-hypertensive drugs, diuretics, limited stress, avoidance of tobacco, low-sodium and/or low-fat diet
