Why is albumin important for the human body?
Albumin is a protein in the body that is made in the liver. Albumin helps to regulate the osmotic pressure of blood which helps maintain the blood pressure.
How are vien and artery the same and different?
Artery walls are muscular allowing the artery to constrict or expand as need be in order to control blood pressure. The blood in arteries is under direct pressure from the heart. Veins contain small little valves so that the blood can only flow in the direction of the heart. Venous blood is under little pressure and relies on these little valves to get the blood back to the heart. As the body moves, this also helps move venous blood along.
What does a frogs artery do?
It helps transports blood in the same effect of a human artery.
How are the jobs of a vein and artery the same?
Whilst the vein carries deoxygenated blood towards the heart and the artery carries oxygenated blood away from the heart and to the muscle, both of the blood vessels are the same in that they both carry blood. The arteries have 'springier', thicker walls as they have to carry the blood at a higher pressure. The flex in the walls helps them to not burst under the pressure.
Is the carotid an artery?
Yes, in fact major artery that helps supply blood to the brain.
How does the structure of the artery allow it to carry out its functions efficiently?
thick cell wall to withstand pressure from the heartit has elastic tissue for elastic recoil to take placeand for an extensionendothelium is folded to expand elastic recoil to let lots of blood through.
What is the function of albumin in blood?
albumin helps to maintain oncotic pressure in the blood
What helps reduce blood pressure for people with high blood pressure?

What is the structure and function of the arteries?
Arteries are blood vessels which carry oxygenated blood away from the heart to the body under high pressure. (Note that the pulmonary artery is the only artery which carries deoxygenated blood to the lungs where it is oxygenated and returns in the pulmonary vein to the heart). The structure of the artery is adapted to this function in several ways. The walls of the arteries are very thick in order to withstand the high pressure. The artery wall is made up of 3 layers, each of which is adapted to serve the function of the arteries.The tunica intima is the inner wall of the artery, and is made up of a layer of smooth endothelium, which reduces friction, covered by a surface of elastic fibres which allow the artery to expand and recoil.The overall function of the elastic fibres is to even out blood flow. When pressure is high they expand, so pressure decreases, and when pressure is lower they recoil, causing an increase in blood pressure. They are not entirely successful in this as a pulse can be felt in the arteries, however this pulse is helpful in propelling blood along through the arteries, together with the action of the smooth muscles.The tunica media is the middle layer, and this comprises a layer of smooth muscle, elastic fibres and collagen. The elastic fibres allow the artery to expand under pressure and then to recoil, causing another surge of pressure which carries the blood forward through the vessels.The tunica externa is the outer layer of the artery wall, and is made up of collagen and elastic fibres. The function of the tunica externa is to prevent over-distention (or over-expansion) of the artery. It is a tough protective outer layer which prevents the artery from bursting when pressure is high.Another characteristic of the artery walls that helps them to serve their purpose is the tiny blood vessels called the vaso vasorum which supply the artery walls with the essential nutrients that they need, including oxygen and glucose which are required for aerobic respiration.The middle and inner layers of the artery wall are nourished by diffusion.Arteries further from the heart will have fewer elastic fibres, as the pressure is less, but more smooth muscle to propel blood along the vessels.
Why do Arteries have very smooth lining inside them?
becuase it does
Is it true that the blood helps to maintain the body's temperature?
YES!
What structure receives blood as it flows from the right ventricle?
The right ventricle will receive blood from the right atria. When the right ventricle then contracts blood will be pushed through the pulmonic valve and into the pulmonic artery. This artery then divides into left and right pulmonic artery. The left going to the left lung and the right artery to the right lung. This blood flow helps the oxygen in your lungs enter your blood to be delivered to all your tissues.
