| Question | Answer |
|---|---|
| Red blood cells | biconcave cells in blood, lack nuclei when mature |
| Iron | Included in hemoglobin molecules |
| Homeostasis | equilibrium in the body ex. stoppage of blood |
| pericardium | tissue that forms loose-fitting sac around heart |
| path of blood flow from vena cava to lungs (4) | right atrium, tricuspid valve, right ventricle, pulmonary semi-lunar valve |
| bicuspid & tricuspid valves | close when ventricular walls contract |
| ventricular systole | Blood pressure is high in systemic arteries (upper #) |
| arteries | strong, elastic vessels that carry blood away from heart |
| venules | cont. from capillaries to form veins, which carry blood back to atria |
| coronary arteries | supplies blood to myocardium |
| capillaries | blood vessels, thin enough to exchange gases between blood and tissue fluid |
| what is blood | made up of platelets, red blood cells, white blood cells, plasma |
| white blood cells | fight off foreign invaders |
| pericardial cavity | fluid inside reduces friction (lubrication) |
| heartbeat | we actually hear the valves closing in the heart |
| pacemaker | sinoatrial node (S-A node) |
| valves | contained in veins, allow blood to flow through, but block other things from flowing back |
| Types of arteries | carotid, femoral, and aorta |
| Types of veins | Jugular, renal vein, iliac vein, inferior vena cava |
| What is the normal blood pressure | 115/75 |
| blood pressure systolic | pressure during ventricular contraction (top # of blood pressure) |
| blood pressure diastolic | ventricular relaxation (bottom # of blood pressure) |
| Types of blood vessels | artery, arteriole, capillary, venule, veins |
| What is the cardiovascular system | It is made up of heart, vessels, and blood |
| What is the function of the cardiovascular system | Transports nutrients to tissues and transports waste from the tissue |
