The capillaries exchange oxygen, nutrients, and waste in cells. They accomplish this via diffusion.
capilaries
capilaries
also known as the red blood cells. They transport oxygen around the body, the tissue is called oxygenated blood. The oxygen is then diffused through the capilaries as they are just thick enough.
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.
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.
Gaseous excange takes place in the alveoli of the Lungs during respiration
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.
Red Blood cells help you get oxygen to your cells
Cells that do not get oxygen will die.
