unit 2 A&P - Heart Sound, Arteries, Vein

Lub (S1)

closure of atrioventricular valves (mitral/tricuspid)

Dub (S2)

closure of semilunar valve (aortic/pulmonary valves) after ventricular contraction

bradycardia

slow heart beat (slower than 60 bpm)

tachycardia

fast heart beat (faster than 100 bpm)

pacemakers

electronic device in chest or abdomen that monitors heart rhythm and sends electrical pulse to help heart beat at normal rate

fibrillation

rapid unsynced contraction of muscle fibers, commonly occurring in heart walls; AFib happens in atria, VFib happens in ventricles which means drop in blood pressure and cardiac arrest

defibrillators

device that delivers shock to heart to restore it to a normal rhythm during cardiac arrest

ascending aorta

descending aorta

thoracic aorta

upper portion of the aorta (largest artery), carries OXYGENATED blood from heart to upper body before going down to lower body

abdominal aorta

carries OXYGENATED blood from heart to lower body

pulmonary trunk

carries DEOXYGENATED blood from right ventricle to the lungs

pulmonary arteries

carries DEOXYGENATED blood from right side of the heart into the lungs so it can pick up OXYGENATED blood

brachiocephalic artery

common carotid arteries

internal carotid arteries

supplies oxygenated blood into brain eye forehead

external carotid arteries

supplies oxygenated blood into neck face scalp

superficial temporal artery

branches off from external carotid artery

vertebral artery

The tiny artery close to the carotid

circle of willis (cerebral arterial circle)

Ring-shaped arteries at the base of the brain that connect the front and back circulation; made up of the anterior communicating artery, anterior cerebral artery, posterior communicating artery, posterior cerebral artery

subclavian artery

axillary artery

brachial artery

radial artery

ulnar artery

intercostal artery

arteries in rib

inferior phrenic artery

hint: phrenic is sheet of muscle that separates chest from abdomen

internal thoracic artery

celiac trunk

gastric (L)

supplies part of the stomach and inferior esophagus

splenic artery

hepatic artery

arteries in the liver; hepatic - associated in liver

renal artery

common iliac artery

external iliac artery

internal iliac artery

femoral artery

popliteal artery

anterior tibial artery

posterior tibial artery

coronary sinus vein

largest vein in heart; collects DEOXYGENATED blood and delivers it to right atrium; sits posterior of the heart in left atrioventricular groove called coronary sulcus (its literally just a groove)

pulmonary vein

carries OXYGENATED blood from the heart to the left atrium of the heart

superior vena cava

inferior vena cava

brachiocephalic vein

jugular vein

carries DEOXYGENATED blood from head, brain, and face towards heart

anterior tibial vein

posterior tibial vein

great saphenous vein

umbilical vein (1)

carries OXYGENATED blood from placenta to the fetus; becomes ligamentum teres

umbilical artery (2)

carries low oxygenated blood from fetus to the placenta; becomes median umbilical ligaments

ductus venosus (ligamentum venosus in newborn)

ductus arteriosus (ligamentum arteriosum in newborn)

foramen ovale (fossa ovalis in newborn)
