NEED TO KNOW SLIDE 4
Aorta branches into brachiocephalic, left subclavian
One branch goes directly to left common carotid artery
Brachiocephalic branches into right subclavian artery and right common carotid
Very first branching out of aorta: right and left coronary arteries, right at base of aorta
Systemic arteries
● Ascending Aorta (2 branches)
◦ R/L coronary arteries
● Aortic Arch
(3 branches) (asymmetrical!)
◦ Brachiocephalic: branches into right common carotid and right subclavian
◦ Left Common Carotid
◦ Left Subclavian
Supply blood to limbs, chest wall, shoulders, back, brain
Subclavian
● Branches
into:
◦ Vertebral
◦ Axillary
Blood supply to pectoral region & axilla (on sides of body and going down)
**Carotid sinus: Baroreceptors, you could cut off blood supply to brain if put too much pressure
on carotid artery**
Vertebral foramena: protects arteries
When the subclavian goes underneath the clavicle it changes name to axillary
Blood supply to the brain
●
R/L Common Carotid arteries (divide at larynx)
◦ Enter at carotid canal of temporal bone

Lumbar – vertebrae, spinal cord, abdominal wall
Celiac trunk splits into all things that service the organs
Splenic artery goes to the spleen
Common hepatic-services the liver
Suprarenal renal: services the adrenal medulla (a part of adrenal gland)
Superior mesenteric: pancreas, small intestine
inferior mesenteric: colon, rectum
Right common iliac and right common iliac goes down to your legs
Mesentary is holding all the arteries supplying the intestine in place
Pancreas in human is different than the cat
left gastric artery going to stomach
Slide 22 and 23 helpful
Blood supply to pelvis and lower extremity

Iliac artery
● External
● Femoral
● to
● Popliteal
● Tibial/Fibular
• Internal Iliac artery: Blood supply to bladder, pelvic walls, external genitalia, medial thigh
• Fibular:Blood supply to lateral/ventral thigh, medial aspect of knee
• Femoral goes from anterior to posterior to bone and then turns into popliteal at knee
• Can get pulse at top of foot at dorsal is pedis
• If break femur could get internal bleeding because has major femoral artery right next to it,
applicable for any big artery
Slide 30 and 31 are big picture
You can skip most of the thoracic regain and go below diagram for vessels
Chapter 22 Lecture 3-Veins
Anything in the book that is blue color is venous blood
Saphenous vein is major difference in naming from arteries
Venous blood is going to superior vena cava
Superior vena to right atrium
Lymphatic system fluids dumps back in at right subclavian
Veins drain back near cerebellum
Blood supply (venous return) from cranium
Superficial Cerebral Veins
Superior Sagittal Sinus
Internal Cerebral Veins
Great Cerebral Vein
Facial
Temporal, Maxillary Vein
R/L Vertebral Veins
**Cephalic: in arm that goes up to head
**Brachial: where you draw blood from, sitting in trochlear notch, has dip so the vein doesn't
move and can see it easily-check this
**Have to absorb nutrients out of GI tract back into blood, this blood supply (venous blood
coming back) absorbs what you ate, is now in venous blood and goes to the liver (hepatic portal
vein), liver samples what is in that blood, liver has its own arterial supply, then from there it will
go back to venous supply go back up to vena cava
**Liver is a big processing center for body
**This is all in the mesentery
