year 10- The Heart Flashcards
(19 cards)
brachiocephalic artery
supplies blood to the right arm, head and neck
surperior vena cava
carries deoxygenated blood from the upper half of the body
pulmonary vein
carries oxygen blood from the lungs to the heart
pulmonary artery
carries deoxygenated blood from heart to lungs
right atrium
pumps deoxygenated blood to the right ventricle which sends it to the lungs
atrioventricular valves
allows blood through one way
Semilunar valves
Prevents blood flowing into the wrong areas
chordae tendinae
the heartstrings- hold the valves in place
right ventricle
pump blood through the pulmonary valve to the lungs
inferior vena cava
carries deoxygenated blood from lower and middle of the body into the right atrium of the heart
Left common cartotid artery
supplies blood to the brain neck and face
left subclavnian artery
supplies blood to the vertebrae
aorta
largest artery- supplies oxygenated blood to the circulatory system
left atrium
holding chamber for blood returning from the lungs and is a pump to the left ventricle
left ventricle
Pumps blood through the aorta to the body
septum
divides the heart’s chambers
what is a hole in the heart?
it is an ATRIAL SEPTAL DEFECT!
- a hole in the wall between the atria
- causes blood to flow from the left atrium and mix with the right mixing deoxygenated and oxygenated blood
- usually closes on it’s own but quelquefois does not
what does an atrial septal defect do?
- causes damage to the blood vessels in the lungs
- high blood pressure
- can lead to lungs and heart failure
- abnormal heartbeat
- increased risk of stroke
what is the cure of an atrial septal defect
CARDIAC CATHETERIZATION
- inserts a tube into a blood vessel in the groin, passing a septal repair device (two connected patches) into the hearts chamber.
- it is permanent
- it takes 3 months for the lining of the heart wall to grow over and seal it completely
