what is gas exchange?
supplying blood cells with oxygen for reespiration and removing carbon dioxide from the blood. It occurs in the lungs.
1 of 9
what is the respiritory system?
the system of organs and structures in which gas exchange takes place.
2 of 9
what is ventilation?
inhaling and exhaling.
3 of 9
what is diffusion?
diffusion is the net movement of molecules down a concentration gradient to reach an equilibrium.Diffusion only takes place in gases or liquids where the particles are free to move. Diffusion is passive-doesnt need enery to take place. high-low
4 of 9
what is osmosis?
is the net movement of water molecules, across a partially permeable membrane. FRom a region of high concentration to an area of low concentration.
5 of 9
what is a hypotonic solution?
is a solution which is less concentrated than the cell
6 of 9
what is a hypertonic solution?
is a solution which is more concentrated than the cell
7 of 9
what is a isotonic solution?
a solution which has the same concentration as the cell
8 of 9
what is active transport?
allows cells to move substances from and area of high concentration. so substances move against the concentration gradient.
