Physiology 2B
Dr. Pavlovitch
Pulmonary Circulation
Pulmonary artery or trunk
r/l pulmonary arteries
r/l pulmonary veins
Systemic Circulation—Arteries
Ascending Aorta Branches
r/l coronary arteries
circumflex artery
anterior descending (interventricular) artery
marginal artery
posterior descending artery (arteries)
Aortic Arch Branches
Brachiocephalic a
R. Subclavian a. (same branches as l. subclavian a.)
R. common carotic a. (same branches as l. common carotid a.)
L. subclavian a.
Internal thoracic a. (mammary)
Vertebral a.  basilar a.  circle of Willis
Axillary a.  brachial a.  radial/ulnar a’s  sup./deep palmar
Arches
L. common carotid a.
Internal carotid a.  (through carotid foramen) to Circle of Willis
External carotid a.  superficial temporal and facial a’s
Descending Thoracic Aorta Branches
Parietal branches
paired intercostals a’s and superior phrenic a’s
Visceral branches
Esophageal a’s, mediastinal a’s, pericardial a’s, bronchial a’s, etc.
Descending Abdominal Aorta
Parietal branches
Inferior phrenic a’s
Paired lumbar a’s
Visceral branches
Celiac a
Hepatic a
Gastric a’s
Splenic a
superior mesenteric a
r/l suprarenal a’s
r/l renal a’s
r/l gonadal a’s (testicular or ovarian)
inferior mesenteric a
Terminal branches
Middle sacral
r/l common iliac a’s
r/l internal a’s (hypogastric)
r/l external iliac a’s
r/l femoral a’s (deep femoral branch) popliteal a
anterior tibial a dorsalis pedis a
posterior tibial a plantar arches.
peroneal a
Systemic Circulation—Veins
**In addition to the pulmonary circuit, there are four principal veins of the
systemic circuit: the coronary sinus, the superior vena cava, the inferior vena cava and
the hepatic portal vein
From the Heart
Cardiac veinscoronary sinus r. atrium (70%)
Veins of Thesbius and sinusoids through heart wall
From the Head, Neck and Shoulder
Diploic veins (from cranial bones)
Emissary veins (from scalp)
 To venous Sinuses
Veins of brain
(sup /inf sagittal sinus
straight sinus
cavernous sinus (from orbits)
basilar sinuses (from ears)
l/r transverse sinuses
l/r sigmoid sinuses)
Venous sinuses 
 Int. Jugular v
l/r Ext jugular v. 
l/r subclavian v 
l/r int jugular 
l/r superficial temporal
l/r facial
l/r ext jugular
l/r subclavian 
 l/r brachiocephalic (innominate)
 superior vena cava
From Each Arm
Deep: sup/deep palmer arches radial/ulnar vbrachial v.-->
axillary v subclavian v.
Superficial: venous arches/network of handcephalic/basilica v. 
median basilica v.
(median cubital v).  axillary subclavian
brachial axillary
From Thorax
Hemiazygos & accessory hemiazygos v. (lft of vert col. brachiocephalic
And azygos v
Azygos v. (L-2 to Sup. VenaCava—left of vertebral column)
*** Azygos veins receive parietal and visceral branches of thoracic veins, such as the
intercostals veins, esophageal veins, etc. The azygos system of veins has anastomoses
with the asc. lumbar veins, the inf. vena cava, the common iliac veins and the renal
veins. Thus, they represent an intermediate blood channel between the sup. vena cava
and inf vena cava. Gastric veins of the portal system anastomose with the azygos system.
Thus portal hypertension (as in cirrhosis) may cause esophageal varices, etc.
***the inferior vena cava begins with the common iliac veins at L-4, follows the aorta up
and through the diaphragm, to the rt. atrium of the heart.
From Abdominopelvic Area
The inferior vena cava receives blood from:
Inferior phrenic veins
Hepatic veins
Rt. suprarenal v. (lft usually empties to renal v.)
Renal veins
Rt. gonadal vein (lft. usually empties to renal v.)
Lumbar v’s (few pair)
Terminal branches
Middle sacral v.
Common iliac v’s
External iliac v’s ( from abdominal wall and lower
extremities)
internal iliac v’s (from pelvic viscera, buttocks,
upper thigh, genitals and inf/middle rectal veins)
From Legs
Deep veins
Plantar venous arch, posterior tibial v, peroneal v  popliteal v 
Dorsal venous arch, anterior tibial v. popliteal v. 
 femoral v. ext. iliac v.
Superficial veins
Dorsal and plantar venous arches and networks 
Greater saphenous vein  femoral v.
& Lesser saphenous vein  deep femoral &/or popliteal v
 femoral v.
Portal circulation
Gastric v’s 
Inf mesenteric v (from last part of lge intestine)  splenic v. 
Sup. mesenteric (from sm intestine and first part of lge intestine) 
Cystic v. 
All the above go to the hepatic portal vein  LIVER –hepatic v. 
Inf vena cava
***The lower rectum blood drains to the int. iliac v’s not the portal system---hence drugs
administered by suppository by-pass the portal system.
