Why are capillaries important in metabolic exchange?

Answer 1

Capillaries allow the exchange of substances between the blood and the cells. They can do this because they have 'leaky walls' which let substances in and out. For instance food is supplied to the cells and carbon dioxide comes out of the cells to be taken away.

Answer 2

Cells need to be near capillaries because capillaries carry blood which in turn brings food/fuel to the cells and removes waste products.

Answer 3

Because they connect your veins and arteries together in order to transport nutrients, air, and circulate blood around the body. Without these, there would be virtually no way to get blood from the arteries to the veins. It is not a good idea to connect the veins and arteries because arteries are very much larger than the beginning of a new vein, so that could be terrible. Overall, yes, capillaries are very important to the circulatory system. But of course, all the main body parts needed to preform the circulation of blood, air, and nutrients are important for basically sustaining our lives.

Answer 4

Capillaries exchange metabolic materials such as oxygen, carbon dioxide and glucose between blood and body cells. The blood flow in capillaries is much slower than in other blood vessels. This is important as it allows more time for metabolic exchange to take place.

Answer 5

Cells need to be near capillaries because capillaries carry blood which in turn brings food/fuel to the cells and removes waste products.

Answer 6

because this take place between the bloob and the tissues

Answer 7

They are the ones that touch each cell allowing oxygen to delivered to every single one.
