There are four pulmonary veins which extend from the left atrium to the lungs. They are the right superior, right inferior, left superior, and left inferior pulmonary veins.
The pulmonary vein is one of four vessels that carry aerated blood from the lungs. 
These veins are the only ones to carry bright red oxygenated blood. 
Together with the pulmonary arteries, they make up the pulmonary circulation. 
This being the processes within the cardiovascular system which is responsible for carrying deoxygenated blood and waste products]]> 2018-01-10 12:59:24 UTC https://padlet.com/321796/r5ofj87460re/wish/220133716 https://padlet.com/321796/r5ofj87460re/wish/220133733 The aorta is the largest artery in the body and has the thickest walls of all blood vessels to allow high blood pressures. The aorta arises from the left ventricle of the heart, forms an arch, then extends down to the abdomen where it branches off into two smaller arteries.  Aorta carries oxygen rich blood to all arteries. ]]> 2018-01-10 12:59:26 UTC https://padlet.com/321796/r5ofj87460re/wish/220133733 https://padlet.com/321796/r5ofj87460re/wish/220133740 Responsible for pumping de oxygenated blood to the lungs

Pumps blood to the pulmonary artery to the lungs 

Blood passes through the tricuspid valve from the right atria into the right ventricle which then contracts and pumps the blood out to pulmonary artery 

Heart failure can happen if ventricles are unable to relax and contract

It permits blood to flow one way only, from the left atrium into the left ventricle.

Bicuspid valve prevents backflow of blood.

The chordae tendineae prevent the eversion, prolapse, by becoming tense thus pulling the flaps, holding them in closed position.

Chordae tendineae resemble thin tendons made of dense regular connective tissue. Most of their mass is made of strong collagen protein fibers, but they also contain elastin protein fibers to provide elasticity and fibroblast cells to repair the protein fibers.]]> 2018-01-10 12:59:43 UTC https://padlet.com/321796/r5ofj87460re/wish/220133793 https://padlet.com/321796/r5ofj87460re/wish/220133848 A Pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles which lead to the capillaries that surround the pulmonary alveoli.]]> 2018-01-10 12:59:57 UTC https://padlet.com/321796/r5ofj87460re/wish/220133848 daniellamming https://padlet.com/321796/r5ofj87460re/wish/220133951 Located in upper right corner of the heart. One of the 4 hollow chambers within the heart.  Deoxygenated blood entering the heart through veins from the tissues of the body first enters the heart through the right atrium before being pumped into the right ventricle. The muscular walls of the right atrium are much thinner than those of the ventricles and feature a wrinkled flap shaped like a floppy dog ear, known as the auricle. Deoxygenated blood enters the right atrium through three major veins: the superior and inferior vena cava and the coronary sinus.]]> 2018-01-10 13:00:19 UTC https://padlet.com/321796/r5ofj87460re/wish/220133951
