What else can I help you with?
Nutrients wastes and oxygen are exchanged through the walls of what?
In the case of animals, these exchanges occur in the capillaries.
What happens when blood flows through capillaries?
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
Blood capillaries have fast or slow flow?
Capillaries have slow flow. This slow speed maximizes opportunities of diffusion of oxygen, nutrients, and wastes.
What is the use of the capilaries?
The capillaries are the site of diffusion of wastes, oxygen, and nutrients. This allows these materials to enter and leave body tissues.
Blood vessels in the dermis that carry oxygen and food?
Arteries to arterioles to capillaries where exchange occurs. Oxygen and nutrients are exchanged for carbon dioxide and wastes.
What happens to blood when it flows through a capillaries?
As blood flows through capillaries, it exchanges nutrients, wastes, and oxygen with body tissues. This transfer is accomplished via diffusion.
What do the capillary do?
Capillaries are the site of diffusion of materials between the body tissues and the blood stream. These materials include nutrients, oxygen, and wastes.
Where in the circulatory cyctem does nutrients enter and wastes leave the tissues?
The capillaries are the site in the circulatory system where nutrients enter and wastes leave the tissues. The thin walls of the capillaries facilitate this diffusion.
Where does exchange of food oxygen and wastes occur?
Capillaries
What is the function of the capillaries in the human circulatory system?
The function of the capillaries in the circulatory system is to allow diffusion of wastes, oxygen, and nutrients to the tissues. The rest of the circulatory system is designed to move the blood to the capillaries so they can perform this function.
Why are capillaries and not arteries found in aliveonephronsvilli?
The capillaries found in the alveoli, nephrons, and vili are thin-walled and narrow. This size and construction makes it easier for nutrients, oxygen, and wastes to diffuse from body tissues.
Why are capillaries found in alveoli nephrons and villi?
Wherever capillaries are found, these are places where nutrients and wastes are exchanged.
