The heart kind of looks like a royal crown. So in Latin, the word for crown (corona) was used to describe the heart. Thus, coronary means "pertaining to the heart". An artery is a blood vessel leading away from the heart toward another body part. This usually means that an artery is carrying fresh, red blood (oxygen-rich blood). So coronary artery means that fresh blood from inside the heart is being sent to the heart itself! This requires further explanation to those who are understandably confused by this.
The coronary arteries are the blood vessels that supply the heart itself. The heart is a muscle that unselfishly pumps blood to the entire body 24/7- but the poor heart needs blood for itself in order to stay alive. The heart is made of muscle. Inside this muscle is a little system of blood vessels. The coronary artery feeds this heart muscle so that it can continue it's work.
Blood has oxygen and nutrition in it as well as immune system components that help fight disease. All tissues of the body need all of these things to function and stay healthy. The heart is no exception- in fact, in the short-term, it's more crucial for the heart to get this stuff than most other tissues since it works so hard and is drastically affected by infections like those caused by streptococcus ("strep throat") bacteria.
right ventricle
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.
The blood vessels that take oxygenated blood from the right ventricle to the lungs are the pulmonary artery. It is part of the pulmonary circulation.
Pulmonary artery Aorta
in our body there are both, pulmonary artery and pulmonary vein
The pulmonary artery is not part of the aorta.
Pulmonary arteries carry deoxygenated blood from the right ventricle.
The Pulmonary arteries carry deoxygenated blood from the lungs to the heart.
The pulmonary trunk carries blood from the right ventricle of the heart, then splits into the left and right pulmonary arteries. Answer: pulmonary trunk/left and right pulmonary arteries
the pulmonary artery sends blood to the lungs.
pulmonary artery supplies de oxygenated blood to lungs.
the pulmonary artery looks like a tube, I think...
