The structure that is directly involved in gas exchange during respiration would be the alveoli. These are tiny sacs located in the lungs that enable oxygen and CO2 to move through the lungs and the bloodstream. Its main function is for gas exchange. It allows oxygen to diffuse into the blood for transport to tissues and remove carbon dioxide from it as well.
These are properties of water that occur due to the hydrogen bonding in water: cohesion, adhesion, surface tension, high polarity, high specific heat capacity and high heat of vapourization.
These properties makes water to be a unique universal solvent.
considering he surface area-to-volume ratio, what structure does surface area represent?
