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.

∙ 10y agoThe heart is no more than a four chambered pump. Its task is to pump blood around the body's circulation system.

2 What does the aorta do?
The aorta is the largest artery in your body and is connected directly to the heart and it also carries the blood to the rest of your body and disperses the blood to the branches of other arteries extended off the aorta.
Were does blood travel after leaving the right side of the heart?
After blood leaves the left ventricle, it goes through the aortic valve to be pumped throughout the body.
Main artery in the neck?
The are two paired arteries that supply the head. You have the carotid arteries (where you take your pulse in the neck). There are also paired vertebral arteries that run up through the transverse foramen in the cervical vertebrae.
What is the path of blood from the heart to the left big toe?
bicuspid valve-->left ventricle of heart-->aortic valve-->ascending aorta--> aortic arch-->thoracic aorta-->abdominal aorta-->right common iliac artery and /or left common iliac artery (abdominal aorta splits to form right and left common iliac arteries, adjust for which leg you follow) -->right external iliac artery -->right femoral artery -->right popliteal artery-->right anterior tibial artery-->right dorsal pedis artery-->right arcuate artery-->right dorsal metatarsal artery-->right dorsal digital artery-->arteriole-->capillary-->venule-->right dorsal digital vein-->right dorsal metatarsal vein-->right dorsal venous arch-->right great saphenous vein-->right femoral vein-->right external iliac vein-->right common iliac vein-->Inferior vena cava-->right atrium of the heart-->tricuspid valve system is highly interconnected and alternative routes can be followed within the arteries and veins of the lower limbs
What are the differences between an artery and a vein?
Arteries carry blood away from the heart to the other parts of the body. Arteries also have thicker walls as the blood pressure is much higher having a closer proximity to the heart. Veins carry the blood back from the other areas of the body to the heart. Simply put, an artery carries blood out of the heart, and a vein carries blood into the heart.
What blood vessel gives rise to the marginal artery and posterior interventricular artery?
They branch off from the right coronary artery which arises from the aorta.
What kind of vessel gives blood to a capillary?
Either a arteriole on the artery side or a venule on the vein side of the bed.
What transprots arterial blood to the kidney?
Renal artery or renal columns--- the arterial supply of each kidney is the renal artery. As the renal artery approaches the hilum, it divides into segmental arteries, each of which gives off several branchel called interlobar arteries, which travel through the renal columns to reach the cortex.
How does the blood get into the heart?
By the arteries pumping the blood into the heart. The Blood gets to the heat by the Aortic vale, the artery that gives the lung oxygenated blood.
2 What does the aorta do?

Why do you need to stop the flow of blood if someone cuts an artery?
Arteries are what carry the blood to the heart, which supply your heart brain and other functions. When it's cut, you start to lose the nutrients that's supplied, nd if you lose too much blood it results in unconsiousness and death. By stopping the flow of blood, it stops the blood from leaving the body, which gives the artery time to heal.
Gives rise to the right common carotid and right subclavian artery?
brachiocephalic artery
Which material gives strength to an artery?
inelastic protein
How does an oxygen molecule travel from the nose to a leg muscle?
The oxygen molecule will enter the capillary. It will get attached to haemoglobin molecule of the red blood cell. The blood (and the red blood cell) will be carried to left atrium via the pulmonary vein. From there the blood will go to to left ventricle. From there it will be carried to ascending aorta, arch of aorta and descending aorta. Then it will go to abdominal aorta. Then it will go to common iliac artery. Then it will go to common iliac artery. Then it will go to external iliac artery. Then it will go to femoral artery. Then it will go to posterior tibial artery. Then from the proximal end of the capillary there, it will enter the interstitial compartment. From there it will go to the muscle cell.
Were does blood travel after leaving the right side of the heart?
After blood leaves the left ventricle, it goes through the aortic valve to be pumped throughout the body.

The blood oxygen bound to hemoglobin is what?
Oxygenated blood is carried through the body by arteries. There is one exception though - the pulmonary artery carries de-oxygenated blood to the lungs; the pulmonary vein returns to the heart carrying oxygenated blood.
