function and location of the veins and arteries

pulmonary trunk (location)

above the pulmonary arteries

inferior vena cava (location)

behind, the abdominal cavity. This vein also runs alongside the right vertebra column of the spine. this is the result of two major leg veins coming together. These leg veins are called iliac veins.

mitral valve (location)

between the left atrium and the left ventricle

inferior vena cava (function)

carries deoxygenated blood from the posterior portion of the body and to the right atrium

superior vena cava (function)

carries deoxynegated blood from the upper half of the body to the heart's right atrium

tricuspid valve (function)

deoxygenated blood enters the right side of the heart via the inferior and superior vena cava. the blood collects into the right atrium, and it must flow through this before entering the right ventricle. it contains three falp-like cusps, and when closed these cusps keep flood from regressing back into the right atrium

fossa ovales (location)

depresseion in the right atrium of the heart

pulmonary trunk (function)

divides to form the left and right pulmonary arteries

superior vena cava (location)

formed by the left and right brachiocephalic veins. near the left subclavian vein and aortic arch

tricuspid valve (location)

forms the boundary between the right ventricle and right atrium

left anterior coronary artery (location)

just above the left ventricle

left atrium (location)

just above the left ventricle

pulmonic valve (location)

lies between the right ventricle and the pulmonary artery and has three cusps

aortic valve (location)

located between the left ventricle and the aorta

left ventricle of the heart (location)

located in the bottom left portion of the heart below the left atrium, and is the thicket of the heart chambers

right atrium (location)

located just above the right ventricle

interventricular sulcus (location)

located under the coronary vein on the heart; the "little valley"

right pulmonary artery (function)

longer than the left pulmonary artery; transports deoxynegated blood to the lungs

right pulmonary artery (location)

on right under the pulmonary trunk

left pulmonary artery (location)

on the left under the pulmonary trunk

mitral valve (function)

prevents the back flow of blood as it is pumped from the left atrium to the left ventricle

aortic valve (function)

prevents the back flow of blood as it is pumped from the left ventricle to the aorta

right ventricle of the heart (function)

pumps deoxygenated blood to the main pulmonary artery

left ventricle of the heart (function)

receives blood from the left atrium and pumps it to the aorta

left atrium

recieves blood from the pulmonary veins and returns it to the heart

right atrium (function)

recieves blood from the superior vane cave

left anterior coronary artery (function)

supplies blood to the front of the heart

fossa ovales (function)

the remnent of a thin fibrous sheet that covered the foramen ovale during fetal developement

pulmonic valve (function)

this divides the right ventricular outflow tract from the pulmonary artery. in normal conditions, the pulmonic valve prevents regurgitation of deoxynegated blood from the pulmonary artery back to the right ventricle.

right ventricle of the heart (location)

this is located in the lower right portion of the heart below the right atrium and opposite of the left ventricle

left pulmonary artery (function)

transports deoxynegated blood to the lungs
