Cardiovascular System
| Question | Answer |
|---|---|
| Artery; | carries blood away from heart |
| Arteriole; | smallest arteries |
| Capillary; | smallest blood vessels - exchange materials with tissues |
| Venule; | smallest veins |
| Vein; | carries blood to the heart |
| Internal conduction system; | pathway of electrical signals that cause heart to contract |
| Pulmonary circuit; | carries blood to and from lungs, oxygenated it |
| Systemic circuit; | carries blood to and from tissues, oxygenates them |
| Jugular vein; | in neck, drains deoxygenated blood from head |
| Carotid artery; | in neck, supplies oxygenated blood to head |
| Superior and inferior vena cavae; | empty blood returning from body into right atrium |
| Pulmonary vein; | carries oxygenated blood from lungs to heart |
| Pulmonary artery; | carries deoxygenated blood from heart to lungs |
| Aorta; | carries blood out of the left ventricle |
| Coronary artery; | carries oxygenated blood to cardiac muscle |
| Coronary vein; | carries deoxygenated blood from heart to right atrium |
| ECG/EKG; | machines that measure electrical signals to detect cardiac muscle damage |
| Defibrillator; | machine that shocks the heart to restart electrical signals |
| Systolic blood pressure; | higher pressure when heart is pumping blood |
| Diastolic blood pressure; | lower pressure when heart relaxes |
| Stroke; | lack of oxygen to the brain, brain tissue dies; blood clot or blood vessel leakage |
| Blood flow through the heary and body in order; | SVC, RA, tricuspid valve, RV, pulmonary valve, pulmonary trunk, pulmonaru arteries, lungs, pulmonary veins, LA, bicuspid/mitral valve, LV, aortic valve, aorta, arteries, arterioles, capillaries, venules, veins, IVC |
| Which vessels carry oxygenated blood? | systemic arteries and pulmonary veins |
| Deoxygenated blood; | systemic veins and pulmonary arteries |
| Hypertension; | high blood pressure |
| Atherosclerosis; | fatty deposits in arteries; block blood flow |
| Angiogram; | imaging to detect fatty deposits |
| Myocardial infarction; | heart attack = oxygen deprivation to the cardiac muscle, so it dies |
| Function of valves; | to prevent the backflow of blood |
