Where does carbon dioxide exchange with oxygen?
they exchange in the aveoli and capillaries
How can capillaries allow gas exchange?
Large surface area + small radius for diffusion.
What substances make up the urine?
Urine consists of Urea, salts and other waste products that do not get reabsorbed into the blood capillaries. It also consists of water
Where are oxygen and carbon dioxide exchanged in the body?
The alveoli sacks have many capillaries and the exchange occurs. O2 from the lungs hits the blood and CO2 is just given off.
Why these pure substances come up into mixtures?
we will mix if the pure substance come up
Does the exchange of substances happen next to the blood capillaries?
this is a false statement blood capillaries do not exchange in diffrent part of your body
Why exchange of substances blood and cells take place through capillaries?
Capillaries have thin and permeable walls which allow the exchange of substances (such as nutrients, oxygen and CO2) to occur. This enables substances to dissociate throughout the entire body (as capillaries are present throughout the entire body).
What is the small blood vessel Small and thin and porous enough to exchange substances to tissue cell?
The circulatory system because the artery and the heart is their.
Which substances are exchanged between the blood in the capillaries and the air in the alveoli?
Oxygen, carbon dioxide, and water are the substances exchanged between the alveoli (air sacs) and the capillaries in the lungs.
The vessels that permit exchange of materials between the cells and the blood are termed?
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Which blood vessels are only ones small enough to exchange substances o the tissue cells?
Capillaries
What blood vessels allow the exchange of substances between the blood and the cells of the body?
Capillaries via osmosis
The two way exchange of substances between blood and body cells occurs only through?
capillaries
Capillaries exchange food oxygen and what?
They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.
How can substances move across capillaries?
Substances typically move across capillaries via diffusion.
What is the function of the capillaries in the respiratory system?
Capillaries are the connection between arterioles and venules. The capillaries job is to enable the exchange of oxygen, water, carbon-dioxide, chemical substances and various nutrients to between blood and the surrounding tissue.
What is the function of capallaries?
The capillaries serve as the bridge between arteries and veins where the exchange of chemical substances inside the body occurs.
