Term | Definition |
Right Atrium | chamber that receives oxygen-poor blood from the body |
Mitral Valve | controls bloodflow between the left atrium and left ventricle |
Left Ventricle | chamber that pumps oxygen-rich blood to the body |
Vena Cava | inferior and superior blood vessels that receive oxygen-poor blood from the body |
Pulmonary Veins | blood vessels that carry oxygen-rich blood from the lungs |
Aortic Valve | controls bloodflow between the left ventricle and aorta |
Pulmonary Arteries | blood vessels that carry oxygen-poor blood to the lungs |
Tricuspid Valve | controls bloodflow between the right atrium and right ventricle |
Pulmonary Valve | controls bloodflow between the right ventricle and pulmonary arteries |
Left Atrium | chamber that receives oxygen-rich blood from the lungs |
Lungs | organs of respiration |
Right Ventricle | chamber that pumps oxygen-poor blood to the lungs |
Aorta | blood vessel that carries oxygen-rich blood to be distributed throughout the body |
Arteries | blood vessels that carry blood away from the heart |
Veins | blood vessels that carry blood toward the heart |
Coronary Arteries | blood vessels that supply the heart muscle with oxygen-rich blood |
Capillaries | where the smallest arteries and the smallest veins exchange nutrient/waste products |
Erythrocytes | (red blood cells) carry oxygen/nutrients or carbon dioxide/waste |
Leukocytes | (white blood cells) fight infection |
Thrombocytes | (platelets) help the blood to clot |
Anemia | Inadequate number of red blood cells, hemoglobin, or both |
Aneurysm | Saclike formation in the wall of an artery |
Arteriosclerosis | Hardening or thickening of the arterial walls |
Atherosclerosis | A fatty deposit on the walls of arteries |
Embolus | foreign substance circulating in the blood vessels |
Hemophilia | Disease characterized by failure of the blood to clot |
Hypertension | High blood pressure |
Leukemia | Malignant disease with large numbers of immature white blood cells |
Myocardial Infarction (heart attack) | Blockage in the coronary arteries of the heart |
Phlebitis | Inflammation of the veins with formation of a clot |
Varicose veins | Dilated swollen veins |
Pulse | pressure of blood pushing against the wall of an artery as the heart pumps |
Pulse Sites | radial (wrist) and carotid (neck) |
Blood Pressure | Measure of the pressure or force of the blood exerted on the walls of arteries while the heart is at rest and contracts |
Systole | Pressure on the walls of arteries when the left ventricle contracts, pushing blood into the arteries (top number in blood pressure) |
Diastole | Constant pressure when the heart is at rest (bottom number in blood pressure) |
CPR | Cardiopulmonary Resuscitation |
AED | Automated External Defibrillator |
Pulse | Measures heart beats per minute by measuring the the number of times the blood pushing against the wall of an artery as the heart pumps |
2 places to take pulse | Radial and Carotid Arteries |
Normal Pulse at rest | 60-100 beats per min |
Normal blood pressure | 120/80 |
Average amount of blood in an adults | 4-6 quartts (5 Liters) |
Blood pressure is taken above which artery | Brachial Artery |
During "hands only" CPR how many chest compressions per minute should be done? | 100 |
Actions if see an adult or teen suddenly collapse | 1) tap shoulder and ask if ok, 2) call 911, 3) get AED (if available) 4) start chest compressions |
During CPR, push the chest hard enough to move the chest? | 2 inches |
