Refers to the alternating surges of pressure in an artery that occur with each contraction and relaxation of the left ventricle.
The pulse is most often taken at the lateral aspect of the wrist, above the thumb, compressing the _____ artery.
sounds of Korotkoff
The _______ are characteristic sounds that indicate the resumption of blood flow to the artery being occluded when taking blood pressure.
atrial relaxation and ventricular contraction
Follows atrial contraction in the cardiac cycle and lasts 0.3 second.
Follows atrial relaxation and ventricular contraction in the cardiac cycle and lasts 0.4 second.
the alternate contraction and relaxation of the myocardium and the opening and closing of valves
What are two different types of phenomena that control the movement of blood through the heart?
Referred to as S1 and is associated with closure of the AV valves at the beginning of ventricular systole.
Referred to as S2 and occurs as the semilunar valves close and corresponds to the end of the systole.
right sternal margin over fifth intercostal space
Where would you place a stethoscope in order to hear the bicuspid valve more clearly?
pulmonary semilunar valve
Which valve closes first, the aortic semilunar valve or the pulmonary semilunar valve?
second intercostal space, right of the sternum
Where would you place a stethoscope in order to hear the aortic valve more clearly?
second intercostal space, left of the sternum
Where would you place a stethoscope in order to hear the pulmonary valve more clearly?
Any large differences between pulse values. May indicate cardiac impairment, low cardiac output, or abnormal heart rhythms.
The pressure the blood exerts against any unit area of the blood vessel walls. Generally measured in the arteries.
cold pressor test
A blood pressure test in which one hand is immersed in unpleasantly (even painfully) cold water.
An organ can remain viable even though its main arterial supply is occluded, as long as these are still functional.
Serve as filters for the lymphatic system and occur at various points along the lymphatic vessels.
Three characteristics of the immune response are the ability to distinguish self from non self, memory and
T cells mediate ______ immunity because they destroy cells infected with viruses and certain bacteria and parasites.
(1) transports tissue fluid, (2) protects the body by removing foreign material
Two functions of the lymphatic system
Picks up leaked fluid and carries it to lymphatic collecting vessels and trunks.
