Pulmonary Circulation
Carries blood from the right ventricle into the lungs then back into the left atrium of the heart.
Systemic Circulation
Larger circulation, it provides blood supply to the rest of the body.
Artery
Carries blood from the heart into the arterioles
Arteriole
Resistance vessels, the contraction and relaxation of the muscle changes vessel diameter, which alters resistance to blood flow.
Capillaries
Called exchange vessels because nutrients, gases, and wastes exchange between the blood and interstital fluid.
Venule
A vessel that carries blood from a capillary to a vein
Veins
Blood vessels that carry blood back to the heart
Aorta
The largest artery in the body; it conducts freshly oxygenated blood from the heart to the tissues.
Ascending Aorta
Branches off the left ventricle, carries oxygen rich blood to parts of the body above the heart
Arch of the Aorta
Arch where the Ascending Aorta and Descending Aorta meet.
Descending Aorta
Branches off the left ventricle, carries oxygen rich blood to the torso and legs (below the heart)
Thoracic Aorta
the next portion of the descending aorta located in the thoracic region, branches off into two major arteries
1.bronchial arteries 2. mediastinal arteries
Abdominal Aorta
The part of the descending aorta that supplies blood to structures below the diaphragm.
Right and Left Coronary Arteries
Are the first branches of the ascending aorta and supply oxygen to the myocardium, because oxygen is essential for normal myocardial contraction.
Brachiocephalic Artery
The main artery arising from the arch supplying blood to the right arm and head.
Left Common Carotid Artery
Supplies blood to head and neck.
Left and Right Subclavian Arteries
Supply blood to the shoulders and upper arms.
Intercostal Arteries
Arise from the aorta and supply the intercostal muscles between the ribs.
Celiac trunk
Hepatic, gastric, and splenic arteries branch off from this artery.
Superior Mesenteric
Artery that supplies most of the small intestine, and part of the large intestine.
Inferior Mesenteric
Artery that supplies the last half of the large intestine.
Renal Arteries
Arteries that supply blood to the kidneys.
Gonadal Arteries
Testicular arteries (testes) ovarian arteries (ovaries).
Lumbar Arteries
Supplies the vertebrae, spinal cord, and abdominal wall.
Common iliac Arteries
Two large arteries which are divisions of the descending aorta. They serve the pelvis, lower abdominal wall, and the lower limbs.
Dorsalis Pedis Artery
Arterial supply to the top of the foot; formed from the anterior tibial artery. Pulse point.
Superficial Veins
Located near the body surface of the skin and can be seen.
Deep Veins
This type of veins run alongside deep arteries and conduct most of the venous return from the legs.
Vena Cava
Largest Vein in the body. Divided into the Superior Vena Cava and Inferior Vena Cava.
Superior Vena Cava
A vein that is the second largest vein in the human body and returns blood to the right atrium of the heart from the upper half of the body.
Inferior Vena Cava
Carries blood from lower regions of the body to right atrium.
Axillary Vein
Vein that drains the arm.
Subclavian Vein
Recieve blood from the axillary veins and from the jugular veins. Blood is carried by these veins to the brachiocephalic veins that empty into the superior vena cava.
Cephalic Vein
Runs on lateral side of the upper limb and drains into the axillary vein.
Basilic Vein
A vein that drains the back of the hand and forearm and empties into the axillary vein.
Median Cubital Vein
Superficial vein of the upper arm that connects the cephalic vein with bascilic vein.
External Jugular Vein
A branch off of the brachiocephalic vein that extends through the throat and is closer to the outside.
Internal Jugular Vein
Major vein that drains venous blood from the brain.
Brachiocephalic Vein
Veins formed by the union of the internal jugular and subclavian veins.
Azygos Vein
Drains thorax and empties into superior vena cava.
Tibial Veins
Veins of the lower leg.
Peroneal Veins
These two veins enter the popliteal vein proximal to the knee.
Femroal Vein
In the thigh.
External iliac Vein
Continuation of the femoral after it crosses into the pelvic cavity, receives blood from the lower limbs, pelvis, and lower abdomen.
Great Saphenous Veins
Longest vein in the body, in the leg.
Renal Vein
One of two large veins that carries blood from the kidneys to the inferior vena cava.
Hepatic Veins
Take blood out of the liver and inferior vena cava.
Cartoid Arteries
Carries blood to the brain.
Vertabral Arteries
Blood in the brain.
Portal Veins
Is a large vein that carries blood from the organs of digestion to the liver.
