How does diffusion take place in digestive systems?

Answer 1

In mammals diffusion occurs at 2 places in the respiratory system. The first place it occurs is in the lungs. The carbon dioxide from the blood diffuses into the lungs and the oxygen in the lungs diffuses into the blood. The second place where diffusion occurs is at the cell. Carbon dioxide diffuses out of the cell and into the blood whereas oxygen diffuses into the cell from the blood. Glucose is also diffused from the capillary to the respiratory cells, since they need energy to function properly.

Remember that diffusion works in a certain way:

Molecules in a highly concentrated area will naturally diffuse into an area with lower concentrations of that particular substance, until eventually all of the molecules of that substance are evenly spread out within that area.

Answer 2

In the digestive system, absorption means the uptake of digested food into the blood. Diffusion is one way in which food can be absorbed into the blood. If the concentration of food is higher in the intestine than it is in the blood, food can diffuse down the concentration gradient into the blood. If the concentration of food is lower in the digestive system than in the blood then it cannot be absorbed by diffusion. The alternative process is active transport (or ctive uptake). This is the use of energy to 'pump' substances against their concentration gradient.

Answer 3

Diffusion and osmosis are very important as they determine the chemicals that enter and exit the cell. The diffusion and osmosis processes are very essential for the proper functioning of the cells.

Answer 4

Diffusion works by mixing particles with different penises.

Answer 5

Diffusion is how the nutrients are absorbed in the digestive system. The digestive system breaks down nutrients which then diffuse and are absorbed by the body.
