What is the function of simple epithelial tissues?
They are designed to exchange materials such as the alveoli exchange gases or the capillary walls exchange fluid and nutrients with the intestitial tissues.
How does your body adapt surface area-to-volume ratios to help exchange gases?
By providing a large area in the lungs.
Describe the exchange of substances across the capillary cell membrane?
Capillary exchange... You have a higher blood pressure and a lower osmotic pressure at the arteriole end of the capillary, this causes water to leave the capillary. The gases oxygen and carbon dioxide and nutrients like glucose and amino acids follow their concentration gradients and diffuse across the capillary membrane. At the venule end of a capillary your blood pressure is less than that of osmotic pressure and water returns to the capillary.Hope this helped. I'm Looking for diagrams of this same thing. Any ideas?Here is a website I found that might help out too.http://www.mhhe.com/biosci/esp/2002_general/Esp/folder_structure/tr/m3/s10/trm3s10_2.htm
The layers through which the respiratory gases diffuse are known as the?
Alveolar-capillary membrane
Gas exchange occurs at the respiratory membrane between the?
The membrane of the alveolus, the air sacs in the lungs where this process takes place, is only one cell thick. The wall of the capillary running adjacent to the alveolus is also one cell thick, so the gases are exchanged between the alveolus and the capillary cell membranes.

What blood vessels do the exchange of gases occur?
the blood vessel which allows gas exchange to occur is the capillaries
How does your body adopt surface area to volume ratio to help exchange gases?
The respiration system adopts to the surface area to volume ratio to help the exchange of gases.
Which part of root is involved in the exchange of respiratory gases in plants?
Root Surface
Small blood vessel connecting arteries and veins that allows the exchange of gases and nutrientd bteween the cells and the blood?
Capillary vessels.
Leaves have what on the lower surface?
Stomata that can help plants to exchange gases.
What gases are exchanges in air sacs?
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
Three ways in which the lungs are adapted for gas exchange?
Many alveoli-increases surface area for gas exchange Thin alveolar wall-allows gases to diffuse easily and fast Thin capillary wall-easy diffusion Inner wall of alveoli-allows gases to dissolve, which they need to enter the capillary
What is the capillary and what is it main function?
The capillary is the smallest type of the vessels . it consists only of two epithelial cells. and its main function depends on its permeability . so , it is the main site for exchange of nutrition and gases. from the tissues to the circulation and from circulation to the tissues .
what is something natural that is about 7 m high?
exchange gases through their moist body surface ?
What happen in the capillaries?
Capillary exchange- exchange of gases- internal or tissue respiration
