What is the medical term meaning produced by the expansion and contraction of blood as it moves through an artery?
Pulse
Why artery called resistance vessels?
The contraction and relaxation of the smooth muscle in their walls can change their diameter, thus changing the level of pressure (large diameter yields low pressure and smaller diameter yields high pressure).
What is relaxation of the smooth muscle in the artery wall which causes the artery wall to become larger?
Vasodilation
What is the process called which involves the contraction of smooth muscle in the artery wall reducing the diameter of the lumen?
Vasoconstriction is normal contraction of smooth muscle in the artery wall.
What is The surge of blood in an artery caused by the heart contraction?
Pulse
What are the two heartbeat sounds?
The normal sinus rhythm sounds like a "lub-dub". The "lub" is the sound of the two atrioventricular valves (mitral for left atrium to left ventricle, tricuspid for right atrium to right ventricle) closing immediately after atrial contraction and then relaxation. The "dub" is the sound of the two sumilunar valves (aortic for left ventricle to aorta, pulmonary for right ventricle to pulmonary artery) closing immediately after ventricular contraction and then relaxation.
What is the expansion and recoil of an artery called?
pulse
