pacemaker of the heart

A

the tissue in the right atrium that begins the heart beat

21
Q

inferior vena cava

A

a large vein that carries blood from the legs, feet, and organs in the abdominal-pelvic cavity to the heart

22
Q

aortic semilunar valve

A

the valve between the left ventricle and the aorta

23
Q

chordae tendonae

A

thread-like bands of fibrous tissue which attaches to the palpatory muscles and bi/tri cuspid valves

24

stroke

A

a blockage in the blood vessel tot he brain

27
Q

capillary

A

smallest blood vessel

28
Q

4 things about veins

A

-carries blood back to the heart
-oxygen poor (for the most part)
-valves to prevent any blood backup
-60% of all blood

29
Q

bicuspid (mitral) valve

A

the valve that lies between the left atrium and ventricle, consisting of 2 flaps of tissue called cusps

30
Q

right atrium

A

one of the 4 chambers of the heart, it receives oxygen low blood from the body, emptying into the right ventricle

31
Q

left atrium

A

one of the 4 chambers of the heart, it receives blood full of oxygen from the lungs, emptying into the left ventricle

32
Q

6 things about afteries

A

-oxygen rich (mostly)
-carries blood away from the heart
-has think walls in comparison to veins

-decreases in size the further it is from the heart
-40% of all blood

33
Q

atria

A

receiving chambers, dump blood into ventricles

34
Q

right ventricle

A

one of the 4 chambers of the heart, it pumps oxygen poor blood to the lung via pulmonary artery

35
Q

AV node

A

specialized conductive tissue at the base of the wall between the upper heart chambers
