A gas exchange (also called difusion) occurs between the alveoli of the lungs and the surrounding capillaries. The alveoli give oxygen into the bloodstream to be transported to the heart while the capillaries give the alveoli carbon dioxide to be removed from the body by exhalation (breathing out).
Afterwards capillaries give nutrients and oxygen to all the cells of the body whilst taking out wastes to later be removed from the body.
Hope this helped.
exchange takes place between capillaries and nephrons. wastes move from capillaries to nephrons.chemicals move into nephrones form capillareis and pH are balanced,keeping body in homeostasis state.
Diffusion!
a kleenex
oxygen and carbon dioxide
These cells get nutrients through simple diffusion. Diffusion allows substances to move between each other, and nutrients diffuse into the cells of the sponge.
All blood vessels allow gases, such as oxygen and nitrogen, as well as liquids, enzymes, etc, to pass through them. Food particles, once absorbed by the small intestines, become part of this process.
Capillaries allow Glucose and oxygen to move out of the blood in the capillaries into interstitial fluid and into the cells. Fluid is exchanged between capillary blood and interstitial fluid.
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.
to move nutrients to the individual cells of the body
The capillaries allow diffusion of nutrients, waste, and oxygen through their walls, which are one cell thick. This diffusion allows transportation of nutrients and waste materials throughout the body.
by covering alot of surface area the capillaries help absorb nutrients and transfer them into the blood
diffusion using capillaries and tissue fluid
Easy exchange of gases They can reach smaller parts Easy diffusion Easy blood flow Easy exchange of material.....
Pure diffusion ... everything flows from high concentration toward low. No energy is expended in these exchanges.
GLUT transporters allow glucose to move down its concentration gradient in the capillaries to the cells where it is needed.
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
wont allow gases to move though the plants cuticle
