Question

Proper difference between tube like and sac like digestion​

Answer 1

Explanation:

1. like the name suggests, the sac like digestive system is just a bag with one opening; the food gets in through that opening, gets digested, and the waste come out of the same opening

2. the tube like digestive system is literally a tube; it has 2 openings. food goes in from one opening, gets digested as it passes through the tube, and waste is excreted through the other opening.

3. it might be gross, but to visualize a sac like digestive system, imagine that you have no anus and you must eat and poop through your mouth. that basically sum up the sac like digestive system.

Answer 2

1. sac-like digestive system

• A sac-like digestive system has a single opening. Food travels into it through that, gets digested and excreta comes out of the same opening. For example, Platyhelminthes. This is also known as a digestive cavity.

1. Tube-like digestive system

• In a tube-like digestive system there are two openings. The food enters through one, gets digested and moves out of the other one in the form of excreta, after the digestion is done. Human beings have this type of a digestive system. this is also known as a digestive tract.
