Lab Quiz 2: Human Blood Vessels

Arteries vs. Veins

Aorta & it’s parts

Brachiocephalic artery

Common carotid artery

Subclavian artery

Brachial artery

Arteries supply oxygenated blood to organs away from heart (except for the pulmonary arteries, which supply deoxygenated blood to lungs) & veins drain (deoxygenated blood except for pulmonary veins)

The aorta supplies the systemic circulation (body except lungs), parts include…

the ascending aorta- right and left coronary arteries branch from here (supply heart muscle; myocardium)

aortic arch- arching posteriorly and to the left and has 3 branches.

• brachiocephalic trunk(right subclavian artery and right common carotid artery)

• left common carotid artery

• left subclavian artery)

thoracic aorta (descending)- chest

Abdominal aorta- inferior to diaphragm; abdomen and beyond

1st branch of arch (branches into right subclavian artery and right common carotid artery)- supplies right arm, right side of head+neck

2nd branch of arch (left)- supplies to head+neck

3rd branch of arch- supplies upper arm/shoulder (leads to left brachial artery of left arm & the right subclavian artery leads to right brachial artery of right arm)

Supplies upper arm

abdomen

Celiac Trunk (artery)

Renal artery

Superior mesenteric artery

Gonadal artery

Inferior mesenteric artery

1st major branch of abdominal aorta- supplies digestive (stomach, liver, spleen, pancreas, gall bladder)

Supplies kidneys

supplies small intestines (located above large)

Supplies ovaries + testes (gonads)

Supplies large intestines

Common iliac artery

external iliac artery

femoral artery

Pulmonary artery

Gastric artery

Hepatic artery

Terminal end of abdominal aorta- splits to each leg (branch below inferior mesenteric artery

Branches from common iliac artery to each leg- supplies leg

Supplies upper leg (thigh) from external iliac artery

Supplies the lungs (different form other arteries because it carries deoxy blood)

Supplies stomach

Supplies liver

Brachial vein

Radial vein

Brachiocephalic vein

Jugular vein

Subclavian vein

Common iliac vein

external iliac vein

femoral vein

Drains upper arm

Drains lower arm (thumb side)

Drains head, neck, upper extremities (the jugular vein and subclavian vein merge into it which merges into SVC)

Drains the head and neck

Drains upper extremities (shoulders, upper arm)

Drains from lower extremities into the distal end of IVC (the external iliac vein connects to it moving up)

Drains form lower extremities (femoral veins connect moving up)

Drain upper legs/thighs

Hepatic vein

Hepatic portal vein

IVC

Pulmonary vein

Renal vein

SVC

Splenic vein

Gonadal vein

Gastric vein

Drains the liver (after blood is cleaned)

Drains digestive organs; stomach, small/large intestines, spleen, gallbladder and pancreas to liver which “cleans” blood →towards heart

Drains lower extremities/ lower body(below diaphragm)

Drain oxygenated blood from lungs to take to the heart (different from other veins and colored red/acts as supply)

Drains kidneys

Drains upper extremities+head

Drains spleen

Drains gonads (ovaries+testes)

Drains the stomach
