Question

5. Define the following terms.
a) Assimilation
b) Ingestion
c) Mastication
d) Egestion
e) Digestion
f) Peristalsis​

Answer 1

Answer:

Assimilation is the absorption and digestion of food or nutrients by the body or any biological system.

Ingestion is the process of taking food, drink, or another substance into the body by swallowing or absorbing it.

Mastication is chewing

Egestion the act or process of discharging undigested or waste material from a cell or organism specifically : defecation.

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

$\\\tt{\color{gold}{c)\:}}\color{silver}{Mastication\:}\color{aqua}{(चबाना)}$

Mastication is the process by which food is crushed and ground by teeth. It is the first step of digestion and it increases the surface area of food ro allow a more efficient breakdown by enzymes.

$\\\tt{\color{gold}{d)\:}}\color{silver}{Egestion\:}\color{aqua}{(उत्सर्जन)}$

The process by which undigested is eliminated from the body is called egestion.

$\\\tt{\color{gold}{e)\:}}\color{silver}{Digestion\:}\color{aqua}{(पाचन)}$

Digestion is the complex process of turning the food you eat into nutrients, which the body used for energy, growth and cell repair needed to survive. The digestion process also involves creating waste to be eliminated.

• Steps of Digestion

Their are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption and elimination of indigestible food.

$\\\tt{\color{gold}{f)\:}}\color{silver}{Peristalsis\:}\color{aqua}{(क्रमाकुंचन)}$

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. In the large intestine peristalsis helps water from undigested food absorbed into the blood stream.
