The capillaries exchange oxygen, nutrients, and waste in cells. They accomplish this via diffusion.

capilaries
In the body, the circulatory system handles tissue exchange by transporting oxygen, nutrients, and waste products to and from cells. This exchange occurs through the blood vessels, where oxygen and nutrients are delivered to tissues, and waste products are carried away.
It (oxygen) enters the lungs, is absorbed by the alveoli in the walls of the lungs, transferred in red blood cells to the heart, where it is pumped into the aorta, then to the arteries and veins and then the capilaries that feed the hair follicles which reside above the temporalis muscle.
The capillaries are the site of diffusion of wastes, oxygen, and nutrients. This allows these materials to enter and leave body tissues.
Erythrocytes, or red blood cells, are responsible for transporting oxygen from the lungs to tissues throughout the body and transporting carbon dioxide back to the lungs to be exhaled. Their biconcave shape and hemoglobin content allow them to efficiently carry out this function.
to allow for gas exchange (oxygen and carbon dioxide)Capilaries are all over you body but capilaries are a very specific topic for people and medicine students , a specific part were capilaries take place is the respiratory system for example the alveoli which are tiny sacks which are millions of them in our lungs and capiliries cover the alveoli mostly the capilaries are thin because they take out carbon dioxide out of your system.
capilaries. pay attention in class.
Capilaries
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.
Lymph consists on water and disolved materials such as glucose it also contains some white blood cells that have left the capilaries and it comes from the limphatic system.
Red Blood cells help you get oxygen to your cells
