GENERAL HISTOLOGY

Detailed explanation-1: -Visking tubing is a selectively permeable membrane, this means it has pores in it which allow small molecules through but not larger molecules. The apparatus used to model absorption in the small intestine can be set up like this.

Detailed explanation-2: -The Visking tubing of the model gut represents the wall of the small intestine.

Detailed explanation-3: -Visking tubing can be used to model diffusion in the body. Visking tubing is a selectively permeable membrane. It selects which molecules can pass through as it has pores of a certain size.

Detailed explanation-4: -Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated solution) in the Visking tubing across the membrane, increasing the volume of liquid in the Visking tubing, which forces liquid up the capillary tube.

Detailed explanation-5: -Dialysis tubing (sometimes referred to as Visking tubing) is a non-living, partially permeable membrane made from cellulose. It is sometimes used to model the process of digestion and absorption that occurs in the small intestine. More items
