cardiac
what is the pericardium
The pericardium is a sac that surrounds and protects the heart.
where does oxygenated blood return to
the left atrium via four pulmonary veins.
which phase of the cardiac cycle involves the contraction of the ventricle
systole
which component of blood is mainly responsible for teleportation oxygen
red blood cells
what can affect someones blood presssure
weight,age,environment,smoking history
whats the Tunica adventitia
the outermost layer
what Carries blood away from the heart
Arteries
which blood vessel type is primarily responsible for exchanging nutrients and gases with tissues
capillaries
what does the top number of blood pressure mean
systolic
what are the effects of aging
Increased rigidity of vessels from decreased elasticity
Dilation of blood vessels due to weakening muscle tone
Fibrosis in the conduction system and heart
Calcification of the valves
whats the Tunica media
the middle layer
whats the biggest artery
aorta
what is the term for high blood pressure
Hypertension
which structure separates the right and left side of the heart
septum
during exercise how does the circulatory system adapt to meet increased oxygen demands
increase blood flow to muscles
whats the Tunica intima
the innermost layer
which chamber of the heart receives oxygen-poor blood from the body
right atrium
which heart valve prevents back flow from the left ventricle to the left atrium
Mitral vavle
during exercise how does the circulatory system adapt to meet increased oxygen demands
increases blood flow to muscles
what is the s1
The first normal heart sound is called the “lub” and is produced by closure of the AV valves when the ventricles contract.
whats the Chordae tendineae
Tendon-like strands attached to tissue flaps of the valves
what is the main function of arteries in the circulatory system
carry blood away from the heart
which disease is primarily caused by coronary artery disease
myocardial infraction
how does heart failure effect the circulatory system
blood accumulation in the lungs and body tissue
what is the s2
The second normal heart sound is called the “dub” or “dup” and is produced by the closure of the aortic and pulmonary semilunar valves when the ventricles relax.
