They are low in oxygen.
Both of them are arteries. Pulmonary artery supplies blood to lungs whereas Aorta supplies blood to all other parts of the body. Both of them are the outlets of the heart. Pulmonary artery is a part of pulmonary circulation while Aorta is a part of systemic circulation.
Blood vessels have the job of carrying blood to the various parts of the body that needs them. The three main varieties of blood vessel are, arteries, veins and capillaries. Arteries, veins and capillaries vary greatly in size, length and thickness from person.
You tell me that is why I'm asking
The vena cava is purple while the pulmonary artery is blue/green. hope this helps!
compare and contrast the structure of a vein and artery
how? please be more specific!! thanks <3
it moves toward the heart <apex>
the tricuspid valve is alot larger than the pulomonary valve beyaaaaaaaaah
major difference is of pulmonary veins. If we compare the structure of heart the difference lies in the presence of single ventricles.
The blood going out from the arteries is full of oxygen. It delivers that oxygen to the organs, therefore when it returns in the veins, it contains carbon dioxide
the blood comes in the through the superior and inferior vena cava. it then passes through the right atrium and is pushed through by the bicuspid valves. it enters the right ventricles and exits the heart through the right semi lunar valves and the pulmonary arteries and into the lungs. it is then brought back in through the pulmonary veins and passes through the left atrium. it is pushed through by the bicuspid valves and into the left atrimu and exits through the left semi lunar valves and out through the aorta to the rest of the body.
The walls of the left ventricles are very much thicker as compared to the walls of the right ventricle. The left ventricles has to push the blood to whole body. The right ventricle has to push the blood to the lungs only.
