pulmonary circulation

..., circulation of blood between the heart and the lungs

systemic circulation

..., circulation that supplies blood to all the body except to the lungs

arteries

..., blood vessels that carry blood away from the heart

arterioles

..., small vessels that receive blood from the arteries

capillaries

..., the smallest blood vessels which connect the smallest arteries with the smallest veins. Nourishment and fluid noramlly trapped in thick walled arteries and veins can easily pass through the delicate walls of the capillaries

veins

..., blood vessels that carry blood back to the heart

venules

..., smallest veins

tunica intima

..., the innermost layer of a blood vessel, an endothelium

tunica media

..., middle layer of artery; made up of smooth muscle fibers and thick layer of elastic connective tissue

tunica adventitia

..., outer layer of blood vessel; fibrous connective tissue;

conductance vessels

primary function of the large arteries is to conduct blood from the heart to the arterioles, the large arteries are called this

resistance vessels

..., Arterioles, which can selectively constrict or relax to control the resistance to outflow of blood into the capillaries.

exchange vessels

another name for capillaries, since the primary function of capillaries is the exchange of substances between the blood and interstitial fluid

capacitance vessels

Because the veins store blood. Capacitance refers to storage. 70% of total blood volume found on venous side or circulation.

aorta

..., The largest artery in the body; it conducts freshly oxygenated blood from the heart to the tissues.

ascending aorta

The ascending part of the aorta as it emerges from the left ventricle; right and left coronary arteries branch from here.

arch of the aorta

..., The most superior portion of the aorta, Arch where the Ascending Aorta and Descending Aorta meet.

descending aorta

..., the descending part of the aorta that branches into the thoracic and abdominal aortae

thoracic aorta

..., a branch of the descending aorta

abdominal aorta

..., a branch of the descending aorta

brachiocephalic artery

..., a major artery, arising from the arch of the aorta, that supplies blood to the right arm and the head, right neck and shoulder.

left and right subclavian arteries

supply blood to the shoulders and upper arms

intercostal arteries

..., arteries that carry blood to the intercostal muscles

celiac trunk

..., an artery that originates from the abdominal aorta just below the diaphragm and branches into the left gastric artery and the common hepatic artery and the splenic artery

gastric artery

..., arteries that supplies the walls of the stomach

splenic artery

..., an artery that originates from the celiac trunk and supplies blood to the spleen

superior mesenteric artery

..., originates from the upper part of the aorta that supplies the small intestines and the cecum and the colon

inferior mesenteric artery

..., arises near the lower end of the aorta and supplies the large intestine

renal arteries

..., Arteries that supply blood to the kidneys

right and left common iliac arteries

..., Supply the pelvic organs, thighs, and lower extremities.

major arteries of the thigh and leg

external iliac arteries, femoral, popliteal, anterior, and posterior tibial arteries

dorsalis pedis artery

..., artery supplying the foot, lateral to the large tendon of the big toe

superficial veins

..., located near the body surface

deep veins

..., located within the tissues and away from the body surface

vena cava

..., either of two large veins that return oxygen-depleted blood to the right atrium of the heart

superior vena cava (SVC)

..., veins draining blood from the head, shoulders, and upper extremities

inferior vena cava (IVC)

..., conveys blood from the lower portion of the body (legs and torso) to the right atrium

axiallary vein

drains into subvlavian vein

cephalic vein

..., a large vein of the arm that empties 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

..., The major vein of the antecubital fossa most commonly used for venipuncture (middle)

external jugular veins

..., Drain blood from the face, scalp, and neck. They empty into the subclavian veins

internal jugular veins

..., blood drain from brains

brachiocephalic veins

..., formed when the subclavian and internal jugular veins join

azygos vein

single vein that drains the thorax and empties directly into the subclavian veins.

tibial veins & peroneal veins

Drain the calf and foot region

great saphenous veins

..., Longest veins in the body

renal veins

..., The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava.

encephalopathy

..., any disorder or disease of the brain

carotid arteries

..., the major arteries that carry blood upward to the head

right common carotid artery

...arises from the brachiocephalic artery

left common carotid artery

arises directly from the aortic arch

external carotid arteries

..., supply blood to the face, scalp, and neck.

internal carotid arteries

..., supply blood to portions of the brain.

vertebral arteries

..., branch from the subclavian arteries. They travel superiorly through the foramen magnum where they join to form the basilary artery.

anastomosis

..., a natural or surgical joining of parts or branches of tubular structures so as to make or become continuous

circle of Willis

..., A structure at the base of the brain that is formed by the joining of the internal carotid and basilar arteries

portal vein

large vein that carries blood from the organs of digestion to the liver. superior mesenteric vein & splenic vein combine to form.

superior mesenteric vein

..., the vein that carries blood from the small and first part of the large intestines

splenic vein

..., drains spleen, stomach, pancreas, and inferior mesenteric vein which drains the last part of the large intestine

inferior mesenteric vein

drains the last part of the large intestine

hepatic artery

..., arteries that supply the liver with oxygen rich blood and is a branch of the celiac trunk.

hepatic vein

..., a vein that drains the liver. EX. empties into the vena cava

splanchnic circulation

supplies blood to the stomach, spleen, pancreas, intestines and liver

umbilicus

..., belly button

umbilical cord

..., membranous duct connecting the fetus with the placenta

placenta

..., the vascular structure in the uterus of most mammals providing oxygen and nutrients for and transferring wastes from the developing fetus

umbilical vein

..., A vein in the umbilical cord; returns nutrient blood from the placenta to the fetus.

umbilical arteries

..., carry blood from the fetus to the placenta

ductus venosus

..., the fetal structure that allows most of the blood to bypass the liver and to flow from the umbilical vein to the inferior vena cava

foramen ovale

..., Connects the left and right atria, allowing blood to flow directly from the right to the left side of the heart

ductus arteriosus

..., a blood vessel in a fetus that bypasses pulmonary circulation by connecting the pulmonary artery directly to the ascending aorta. EX. normally closes at birth

pulse

..., the rhythmic contraction and expansion of the arteries with each beat of the heart

hepatic arteries

arteries of the liver
