The digestive tract of the frog is well vascularized because it aids in the absorption of nutrients.
The digestive tract of a frog is a hollow long tube that extends from the mouth to the anus which helps in the ingestion and digestion of food.
The digestive tract of frog has the following characteristics:
- alimentary canal of the frog is not long, that is, it is short.
- It has accessory organs of digestion such as liver, gall bladder and pancreas.
All the digested food substances are absorbed at the small intestine due to the presence of microvilli.
This microvilli is made up of a central core that is vascularized, that is, it contains artery, vein and lymphatic capillary.
Therefore, the vascularized microvilli of the small intestine of frog help in the absorption of nutrients.

Answer: Osmosis is the diffusion of water molecules, from a regions of higher concentration to a region of lower concentration, through a selectively permeable membrane. Osmosis is directly dependent upon the concentrations of the solutes : a dilute solution will contain a higher concentration of water molecules, while a concentrated solution contains a low concentration of water molecules. As, a result of this the level on more concentrated side will rise and cell will get swell. On the other hand the level on less concentrated side the cell will shrink. When concentration is the same on both the sides of the membrane , the movement of water molecules will be the same in both directions. At this point, the net exchange of water will become zero and there will be no changes in the liquid levels.
Osmosis is a natural phenomenon where molecules move from a lower concentration to a region with higher concentration. This occurs through water channel proteins called Aquaporins. This natural phenomenon can occur in cells which can cause shrinking or bursting.
