Can H2O pass through stomata?
Yes most gases do.
What process is when O2 and CO2 pass from the aveoli into the blood system?
External respiration. On the other hand, if the exchange occurs between the blood and tissues, then it's referred to as internal respiration.
If you pass a urine test can you pass a blood test?
yes
How do liquids and gases differ?
Liquids and gases can be categorized differently through many ways, specially through their partcile composition. Liquid particles are close together and pass pass each other easily. In the other hand, gas particles are well separated and have lots of free space to move at high speeds.
What gas can go through water?
Any gas that does not substantially dissolve in or react with water can pass through it. This group includes air (except for its carbon dioxide content), all the noble gases, and all the hydrocarbon gases.
Which blood vessel does blood oxygen pass through?
Oxygen and other gases pass through the capillaries.
What is the name of the air sacs that oxygen from the air to pass into your blood?
alveolus (alveoli)plural. it's purpose is to exchange gases between the air and the body.
What is so special about these blood vessels that's makes it easy for substances to pass in and out?
when blood is in vessel, the blood may be black.
How do you pass a drug test with blood?
Easy: DON'T DO DRUGS. Unless you have a prescription for it.
How can the respiratory system put oxygen into the blood and carbon dioxide out of the blood?
Oxygen and carbon dioxide are both gases, which makes them easier to pass through the cell. In addition, the site of trading the respiratory gases occur at alveoli, which has capillaries attached to it. The membranes in these regions are each one cell thick, which enables the respiratory gases to pass through easier. When the blood reaches the lungs, simple diffusions then take the carbon dioxide out of the cell and oxygenates the blood.
What materials pass from the mothers blood to the babies?
Gases, All small molecules (food, structural materials, minerals); hormones, and antibodies.
Oxygen and carbon dioxide pass back and forth between the alveoli and the blood through?
Oxygen and carbon dioxide easily pass back and forth between the alveoli and the blood through the capillaries.
Which blood vessels are so thin materials can pass in and out of them?
Capillaries, they have gaps between the cells so that red blood cells and nutrients can pass into the tissues to be used
What type of blood vessel lets gases and food move in and of the blood?
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.
Which vessels allow materials to pass between the body and blood cells?
capillaries
What passes through the thin walls of the capillaries?
Blood passes through the capillaries, which provide a passage way for the blood from the arteries to the veins. The tiny, thin walled capillaries also allow for the exchange of gases through the tissue. You can read more about capillaries at fi.edu
What special structures on some stems allow gases to pass through?
Lenticels allow gases to pass through them. Hope this helped. Gigi
