What else can I help you with?
Where chemicals pass between cells and blood?
The walls which allow substances to pass backwards and forwards between the blood and the cells are called capillaries. They are microscopic blood vessels have walls which are 'leaky' which allows substances to pass backwards and forwards. Narrow arteries and veins are connected by capillaries.
Why white blood cells pass through capillaries while red blood cells not?
Both red and white blood cells pass through the capillaries.
Are veins tiny blood vessels that allow substances to pass between the blood and body tissues?
No, capillaries are what allows substances to go from the walls of the small intestine into your cells. Veins are what carry the blood (with cells inside) to the heart to be oxygenated.
State two substances that pass into the blood?
Two substances that pass into the blood include oxygen and carbon dioxide. The blood carries fresh oxygen to the cells and tissues and removes waste materials.
What is the function of interstitial fluid?
Interstitial fluid is the liquid which surrounds the cells in the body. The function of intestitial fluid is to carry substances between the blood and the tissue cells. Substances passing out of the blood capillaries eg food,oxygen, pass through the interstitial fluid to reach the body cells. Substances produced by the cells eg carbon dioxide waste, pass through the tissue fluid to enter the blood capillaries. See: http://en.wikipedia.org/wiki/Interstitial_fluid

Tiny blood vessels that allows food oxygen and other substance to pass the cell?
capillaries
Which blood vessel does blood oxygen pass through?
Oxygen and other gases pass through the capillaries.
Does carbon dioxide pass into the blood?
Carbon dioxide passes into the blood at the capillaries of the systemic circulation. Then it is released at capillaries around the alveoli.
What vessels of the body are thin and small enough to allow materials to pass over the membrane?
Capillaries are the smallest blood vessels in the body and are thin enough to allow for the exchange of materials (such as nutrients, oxygen, and waste products) between blood and surrounding tissues. Their thin walls facilitate this exchange by allowing substances to pass through easily.
What is the body organ which oxygen passes through to capillaries?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Why do capillaries have spaces between endothelial cells?
Capillaries have spaces between endothelial cells to allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues. This structure, known as intercellular clefts, facilitates the transfer of substances through the capillary wall.
