| Question | Answer |
|---|---|
| Space within a blood vessel through which the blood flows | lumen |
| Platelet | thrombocyte |
| Pertaining to blood vessels | vascular |
| When taking a BP what does the 1st heart sound represent and how is it reported? | systole top number |
| State the function for each of the 3 major types of blood vessels | arteries- carries oxygen rich blood away from heart to capillaries capillaries-allow exchange of oxygen, carbon dioxide and nutrients between blood and tissue cells veins- carries oxygen poor blood, carbon dioxide and waste products to the heart |
| Leukocytes- how many per mL and their purpose | 4,500-11,000 per mL provides immunity |
| Name the leukocytes and their functions | T-lymphs- recognizes foreign antigens Eosinophils- increased in allergies Neutrophils- phagocytizes bacteria Monocyte-becomes a macrophage B-lymphs-produces antibodies Basophils-releases antihistamines |
| Blood vessel carrying deoxygenated blood from the tissues to the heart | vein |
| Most common site to check a BP | brachial artery |
| Name a disorder in which FDP's are elevated | DIC |
| Erythrocytes How many per mL, life span, purpose | 4.5-6 million per mL 120 days transports oxygen and carbon dioxide |
| 3 formed elements of the blood and state the function | WBC's- aids immunity RBC's- transports oxygen and carbon dioxide Platelets- clotting |
| Vein that carries oxygenated blood | pulmonary vein |
| 3 layers of the heart | epicardium. myocardium, endocardium |
| Name 2 coag pathways and a test used to monitor each pathway | Intrinsic- ATTP Extrinsic- PT |
| Where is the saphenous vein? | Leg |
| Deficiency of RBC's | anemia |
| Abnormal increase in the # of normal leukocytes in the circulating blood | leukocytosis |
| Contraction phase of the heart | systole |
| One of 2 lower chambers of the heart | ventricle |
| Resting phase of the heart | diastole |
| When you take a pulse you are looking for? | rate, rhythm, and volume |
| Quality of blood pumped by the heart ventricle in one minute and how many liters is it usually | Cardiac output 5 liters |
| Small vein leading from a capillary to a vein | venule |
| Why do veins contain valves? | to keep blood flowing in one direction; prevent backflow |
| Marked abnormal increase of WBC's in marrow and circulating blood | leukemia |
| Thrombocytes- how many mLs, life span, purpose | 140,000-440,000 per mL, 9-12 days, clotting |
| Chamber of the heart that recieves blood from the venae cavae | Right atrium |
| Small arterial branches leading to capillaries | arteriole |
| Blood vessel carrying oxygenated blood from the heart to tissues | arteries |
| One of two upper chambers of the heart | atrium |
| 3 stages of blood coag and the primary process taking place | Primary hemostasis-forms a temporary platelet plug Secondary hemostasis-converts the primary platelet plug to a stable fibrin clot Fibrinolysis- breakdown/ removal of a clot |
| Pacemaker of the heart | SA node |
| Small blood vessel containing arteries and veins that allows the exchange of gases between the cells and the blood | capillaries |
| How does the heart muscle recieve oxygen and nutrients | coronary arteries |
| Pertaining to the heart and blood vessels | cardiovascular |
| RBC | erythrocyte |
| Common site used to take a pulse | radial artery |
| WBC | leukocyte |
| Trace the blood flow | venae cavae right atrium tricuspid right ventricle pulmonary semilunar valve pulmonary artery lungs pulmonary vein left atrium mitral valve left ventricle aortic valve aorta |
