A&P 2 lab blood vessels

ascending aorta

right and left coronary arteries supply heart

aorta arch

Brachiocephalic trunk (or atery)

• right common carotid artery supplying right side of head

• right subclavian artery supplying right shoulder and upper limb

left common carotid artery supplying left side of head

left subclavian artery supplying shoulder and upper limb

descending aorta

• thoracic aorta above diaphragm

• abdominal aorta below diaphragm

trunk

going to branch off

arteries of the head and neck

• common carotid artery divides into internal and external carotids

• external carotid artery supplies most external head structures

• internal carotid artery supplies the middle and anterior portions of the brain

veins of the head and neck - draining blood from brain

• large, thin-walled dural sinuses form between layer of dura mater

• drain blood from brain to internal jugular vein

veins of head and neck - returning blood to heart

• internal jugular vein —> brachiocephalic vein (medial)

• external jugular vein —> subclavian vein —> brachiocephalic vein (lateral)

• R and L brachiocephalic vein —> superior vena cava

arteries of the upper limb

subclavian passes between clavicle and first rib

what vessels change names as it passes to different regions

• subclavian to axillary to brachial to radial and ulnar

Brachial artery is used to find what

BP

radial artery is used to find what

pulse

fetal circulation

fetus receives oxygen and nutrients from mother by way of placenta/umbilical cord

umbilical vein brings

oxygenated blood towards fetal heart

• ductus venosus passes through fetal liver

for fetal circulation, where does much of the blood bypass through?

pulmonary circulation

foramen ovale becomes what (fetal circulation)

right atrium to left atrium and becomes fossa ovale

ductus arteriosus becomes what (fetal circulation)

from pulmonary trunk to aorta and becomes ligamentum arteriosum

less oxygenated blood leaves through what (fetal circulation)

by way of umbilical arteries, going towards placenta
