Why water and dissolved substances leave the arterioles end of the capillary and enter the venule end?
Water and dissolved substances leave the arteriole end of the capillary due to hydrostatic pressure being higher than osmotic pressure and enter the venule of the capillary due to osmotic pressure being higher than hydrostatic pressure.
What happens to blood pressure when the smooth muscle of an arteriole contracts?
When the radius of the smooth muscle decreases the pressure increases. So the blood pressure becomes higher
Water and solutes flow form the arteriole end of the capillaries into the tissues due to what?
Hydrostatic pressure(inside capillary) is higher than osmotic pressure it re-enters the capillary on venule end because inside the hydrostatic pressure is now lessthan osmotic pressure drawing water back in
Is blood pressure higher in capillaries than in veins?
The blood is under low pressure once entering the capillary.
Explain why fires spread faster and are more intense at high temperatures?
At higher temp the moisture on land decreases which makes it easier for the land to catch on fire
When demand decreases and supply decreases what happens?
prices go higher
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
What happens to temperature in the troposphere?
The air temperature decreases as you go higher. On the average temperature decreases about 6.5 degrees Celsius for each kilometer.
What happens as the population decreases?
As a population decreases the death rate is higher or equal to the birthrate.
What happens to density at higher altitudes?
The density of air decreases at higher altitudes.
When you get higher what happens to air pressure?
Air pressure decreases as you go higher.
Is the capillary hydrostatic pressure always higher than the interstitial fluid hydrostatic pressure?
no
