PHS Unit 6, Part 2

Cardiovascular System

TermDefinition
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
