Cellular Gas Exchange Vanessa Chong, Jess Hansen, Sally Snickenberger http://www.stemnet.nf.ca/~dpower/resp/exchange.htm
Cellular Respiration • Respiration: the breakdown of C6H12O6 by O2 • The process is carried out by individual cells • Every cell in the body is no more than 2 to 4 cells away from a capillary • Gas exchange takes place as a result of this process
Why is Gas Exchanged Needed? • Body tissues needs O2 -function: oxygen allows for cellular respiration within the body that provide energy (ATP) -dispose of CO2, a waste product of cellular respiration • Blood in the body responds to this need and exchange takes place between blood in capillaries + body cells
What Gas is Being Exchanged? • Opposite of the Gas Exchange that takes place in the lungs • CO2 in the body tissue is diffused into blood cells (based on concentration gradient) • O2 in the blood cells are diffused into body tissue (based on concentration gradient) • CO2 obtained from body tissue is disposed through exhalation • O2 is used to keep body issue alive + functioning http://people.eku.edu/ritchisong/301notes6.htm
Concentration Gradient • O2 and CO2 are diffused down concentration gradient • Basic Diffusion: Move from a high concentration to a low one
