CVS Anatomy 3 Flashcards
What are the arteries of the upper limb?
subclavian - axillary - brachial - radial and ulnar
What are the veins of the upper limb?
dorsal venous arch - median cubital - splits into cephalic (lateral) and basilic (median) - brachiocephalic vein as junction of subclavian and jugular - forms vena cava
What are the arteries of the lower limb?
abdominal aorta - iliac - external iliac - common femoral - popliteal - anterior tibial forms dorsal pedis - posterior tibial forms fibular and plantar veins
What are the veins of the lower limb?
long saphenous vein, short saphenous. popliteal vein and femoral vein
Where and what do the lower limb veins drain?
short saphenous drains lateral part of lower leg, then drains into popliteal at fossa.
long saphenous drains medial part of entire leg, then drains into femoral vein
What is the passage of blood from the lower limb back to the heart?
femoral - external iliac - common iliac - inferior vena cava at L5 - drains into RA at T8
What are the 8 pulse points of the body?
- superficial temporal and facial - branches of external carotid
- common carotid - branch of aortic arch
- brachial - upper arm
- radial - lateral wrist
- femoral - next to groin
- popliteal - behind knee
- posterior tibial artery
- dorsalis pedis artery - 1st and 2nd toe
What does the right atrium have openings for? What other features?
carotid sinus, SVC, IVC,
fossa ovalis - depression in septum between 2 atria.
musculi pectinate muscle ridges to increase power of contraction
What features does the right ventricle have?
tricuspid valve with 3 cuffs, so 3 pairs of papillary muscles attaching to chordae tendonae.
trabeculae carneae muscle contract and pull chordae tendonae
forms pulmonary trunk
What features does the left atrium have?
openings for superior and inferior left and right pulmonary veins
smooth walls, smaller than RA, against oesophagus
mitral valve
What features does the left ventricle have?
opening for aorta
wall 3x thicker than RA. mitral not tricuspid valve
septum, trabeculae carneae, 2 sets papillary muscles instead of 3.
Where are the 4 valves located anatomically?
APTM
aortic - 2nd right intercostal at sternal border
pulmonary - 2nd left intercostal at sternal border
tricuspid - 4th right intercostal at sternal border
mitral - 5th left intercostal at mid clavicular line
Where do the superior and inferior vena cava lay?
to the right of the aorta, behind the heart
What is at the anterior surface of the heart?
1/3 right atrium, right ventricle and left ventricle
What is at the posterior surface of the heart?
left atrium
