arcuate artery
- supplies blood to toes and other parts of the foot
deep plantar arch
- supply the toes and other parts of the foot
Basilar artery
-it supplies the blood to the spinal cord, medulla oblongata and the pons.
Posterior cerebral arteries
supplies blood to the posterior part of the cerebrum
Posterior communicating arteries
-extend forward to connect the posterior cerebral arteries to the internal carotid arteries
middle cerebral artery
- supply blood to most of the temporal and parietal lobes and part of the frontal lobes
anterior cerebral arteries
extends forward from the internal carotids and curve medially toward each other
anterior communicating artery
-connects the two anterior cerebral arteries
cerebral Arterial Circle
circle of willis
-consists of the posterior cerebral arteries, posterior communicating arteries, anterior cerebral arteries and the anterior communicating artery
Cerebral arterial circle/circle of willis
vessels around the pituitary gland
-basilar artery and two internal carotid arteries supply blood to these rotary vessels
superior vena cava
collects blood returning from the head and the upper extremities into the right atrium of the heart
brachiocephalic veins
two prominant veins
-formed by the forking/bifurcation of the superior vena cava.
-extend upward to right & left & receive blood from internal jugular veins & subclavian veins.
Internal jugular veins
arise from each brachiocephalic vein
-collect blood from a group of dural sinuses in the cranium
subclavin veins
branch from the brachiocephalic veins
-each continues distally as an axillary vein
vertebral veins
descend through the transverse foramina of the cervical vertebrae collecting blood from the cervical spinal cord and the back of the skull.
-they connect to the brachiocephalic veins
external jugular veins
-collects blood from the superficial veins of the head and pass it into the subclavin vein.
azygos vein
-collects blood from the lower back upward into the right thoracic cavity then into the superior vena cava
hemiazgo veins
collects blood from the left thorax and passes int blood into the azygos
axillary vein
-each axillary vein receives blood from the cephalic vein the basilic vein, and the brachial vein
cephalic vein
superficial
passes up the lateral radial side of each arm from the superficial palmar arch t the axillary vein
basilic vein
-superficial
ascend along the medial ulnar side of the arm
brachial vein
paired veins
receives blood from the radial and ulnar veins and then connects to the axillary vein
radial vein
-paired veins
-passes along the radial lateral side of the arm and connects to the brachial vein just proximal to the elbow.
-receives blood from the deep palmar arch
ulnar vein
-receives blood from the deep palmar arch
median cubital
-vein is formed by an anastomosis between the cephalic and basilica veins.

hepatic veins
-collects blood from the liver and pass it into the inferior vena cava
renal veins
collect blood from the kidneys
ovarian & testicular veins
collect blood from the gonads/ovaries/testes.
common iliac veins
near the 5th lumbar vertebra, the inferior vena cava divides to form the common iliac veins.
-each the common iliac vein divides in turn to form an external and internal iliac vein
Internal iliac vein
-inner smaller branch of the common iliac vein
-it collects blood from the pelvic organs
external iliac vein
-it collects blood from the lower extremities
-the external iliac vein becomes the femoral vein
femoral vein
-large
-collects blood from the thigh
popliteal vein
-behind the knee, the femoral vein becomes the popliteal vein
-this vein then divides to form the anterior and posterior tibial veins
posterior tibial vein
-collects blood from the lower leg and foot/plantar arch
Anterior tibial vein
-collects blood from the lower leg and foot/dorsal arch
great saphenous vein
-* it collects blood from the dorsal venous arch
small saphenous vein
short
collects blood from this arch on the lateral side of the foot
hepatic portal vein
receives blood from all of the veins of the hepatic portal system and passes it into the liver
superior mesenteric vein
collects nutrient rich blood form the stomach, small intestines, and most of the large intestine and passes it into the hepatic portal vein
splenic vein
collects blood from the spleen and passes it into the hepatic portal vein
inferior mesenteric vein
collects blood from the lower parts of the colon and the rectum and passes it in to the splenic vein
left and right gastric veins
collects blood from the medial border of the stomach
placenta
is a membraneous connection between the mother and the fetus where maternal and fetal blood come into close contact.
-here the baby gets oxygen and food from its mom and gets rid of waste products
umbilical arteries (pair)
passes through the umbilical cord from baby to placenta
umbilical vein
then carries blood back to the baby through the cord
foramen ovale
the fetus does not use its lungs to breathe.
fetal bypasses route a lot of the blood away from the lungs.
-this is a hole in the inter-atrial septum where blood flows directly from the right atrium to the left atrium
ductus arteriosus
the other bypass/short vessel
-blood flows directly from the pulmonary trunk into the aorta
