Structure of Gaseous Exchange Surfaces in Humans‚ Fish‚ Insects and Frogs Gaseous Exchange is a biological process where oxygen diffuses into the body or bloodstream and carbon dioxide diffuses out of the body or blood stream. This process is different for Humans‚ Fish. Frogs and Insects. Humans: In humans the gas exchange system is known as the Respiratory system. The respiratory surface is the Alveoli located on Bronchial tubes inside of the lungs. The average human adult has about 600 million

Gaseous exchange and transport Movement of chemicals in plants and animals -Chemicals that are being moved into the body‚ within the body or out of the body are gases‚ this movement is known as gaseous exchange. -The gases being moved in our out of the body need to move across the surface area of the body‚ in most cases a special surface area has been developed. -The surface that the gases cross is called the respiratory surface and the gases move across this surface by the process of diffusion

Ion Exchange Chromatography Discussion: The first exercise preformed in this lab was ion exchange chromatography. The purpose of this experiment is to separate molecules based on their differences in charge. Since it is based on charge the amino acids in the cation exchange column‚ if negatively charged‚ flow through the column first because they don’t want to bind to the sodium ions. The positively charged ions will elute last at the highest ph because they bind to the negatively charged beads
