Human digestion is as follows
Alimentary canal :
The digestive system from Oesophagus to the anus is called alimentary canal. It's about 9 m long!
It constitutes following organs namely :
a. Buccal cavity
b. Oesophagus
c. Stomach
d. Small intestine
e. Large intestine
f. Rectum
g. Anus.
Function of the above given respectively :
a. Buccal cavity :
Human take in food through mouth. where which salivary enzymes breaks down starch into sugar.
b. Role of Oesophagus :
It allows passage of food from Buccal cavity to the stomach.
c. Role of Stomach :
Here HCL, mucus and several digestive enzymes mixed with food. Where which HCL males food acidic fit enzymes to action.
d. Role of Small intestine :
This tube has three main divisoms namely - Duodenum, jejunum and ileum. Duodenum is responsible for mixing bile and pancreatic juice with food. Jejunum is middle part going only in man.
Total absorption takes place in the ileum. This ileum has villi on the surface. This villi increases area for absorption. The villi have blood vessels, digested food passes villi to there and enters the blood stream. Which then transfer to liver and then to the heart ♥ .
e. Role of large intestine, anus and rectum :
Food from small intestine moves there. Here the most of water and salt be removed from the waste by absorbtion. This intestine all the passage of faecal matter through the anus.
Digestion in Amoeba is like
Amoeba engulfs tiny particles of food with the help of its false feet called Pseudopodia. This process is called circumvallation. The Pseudopodia close to form a small cavity called food vacuole. Here the enzymes help the breakdown of food into simpler and soluble molecules. This then get absorbed and assimilated and residue is thrown out through the contractile vacuole, as Amoeba has no anus. so it can excrete from any part .
The main similarities between them is that all follows the steps of ingestion, digestion, egestion.
