---|---|
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 |
