(e) stiegeon
Answers
a. INGESTION
b DIGESTION
c.ABSORPTION
d ASSIMILATION
e.EGESTION
SHORT NOTES:
a. INGESTION
It is the process by which the food particles enter the mouth. During ingestion the food enters the digestive tract via mouth and buccal cavity.
b DIGESTION
The breakdown of complex food macromolecules into simpler absorbable form is called digestion. Digestion of food occurs in mouth, stomach and small intestine. The breakdown of particles is aided by the enzymes secreted by the digestive glands into the digestive tract.
c.ABSORPTION
The process by which the digested food particles is absorbed in the intestinal epithelium is called absorption. They reach the circulating blood stream. Absorption of food materials occur mainly in the ileum part of small intestine.
d ASSIMILATION
The process by which the digested particles reach the tissue of target from the blood stream is called assimilation. These assimilated particles are required for the metabolism of tissues.
e.EGESTION
The undigested particles and the remnants of digestion are excreted out of the body by egestion. The waste particles moves to rectum and released as feces through anus.
Unscramble the following to form terms related to steps of digestion and write a short note on it.
- (a) gesintion ⟹ Ingestion
- (b) tidigones ⟹ Digestion
- (c) ptiabosron ⟹ Absorption
- (d) milaassitoin ⟹ Assimilation
- (e) stiegeon ⟹ Egestion
━━━━━━━━━━━━━━━━━━━━━━━━━
Short note on the terms which are related to Amoeba:-
★ Ingestion
⟹ The engulfing of the food when it comes in contact with its cell surface is called Ingestion.
★ Digestion
⟹ Digestion is a process in which complex and large components of food are broken down into their respective simpler and smaller forms.
★ Absorption
⟹ Inside the food vacuole, complex food breaks into small soluble molecules readily observed by the cytoplasm. This process is called Absorption.
★ Assimilation
⟹ When the absorbed food is moved further by Amoeba to drive energy for growth is called Assimilation.
★ Egestion
⟹ The process of throwing out undigested food is called Egestion.
