the branch of science that deals with nutrients and nutrition, particularly in humans.
There are many kinds of nutrition :
Nutrients are elements in feed that are used by the animal for growth and production. Nutrients are normally divided into five categories: Water, protein, carbohydrates, minerals, and vitamins. Water is the main constituent of the body.
Heterotrophic nutrition​ :
Animals show heterotrophic nutrition, that is, they depend on other organisms for their food.​
Which took nutrition system : Removal of waste from the body:
The process and the organs which help in removing the following wastes from the body are enlisted below: -
WasteProcessOrgansCarbon-dioxideExhalationLungsUndigested foodEgestionAnus & Large IntestineUrineExcretionKidneySweatSweatingSweat Glands
Exhalation
It is the passive act of breathing out air that has been inhaled.
The diaphragm relaxes at this point and rises into the chest cavity.
The area of the chest cavity shrinks as a result of the intercostal muscles between the ribs relaxing.
After a while, the chest region shrinks, and the windpipe and nose eventually release carbon dioxide-rich air from the lungs.
Egestion
Food that hasn't been digested into waste must be removed from the organism's body during the procedure.
Discharged materials are undigested food and other toxic substances leftover from digestion.
The mouth or the anus are the primary routes for egestion. (Animals like jellyfish ingest food and expel waste through their mouths.)
Only animals undergo egestion.
Excretion
Excretion is the process by which organisms eliminate harmful substances and metabolic waste from their bodies.
By-products of both metabolic and non-metabolic processes include excretory products.
Animal waste is divided into two categories: metabolic waste and non-metabolic waste.
Sweating
Sweating is an involuntary action that is under the control of the autonomic nervous system.
This is a part of thermoregulation (regulation of body temperature) in the body.
Face, armpits, palms of hands, and soles of feet are certain common sweating areas.
Nutrition help different way:
18 nutrition method
1.Eggs
Eggs are incredibly nutrient-dense and high in protein and fat, which help you feel full.
In a 2020 studyTrusted Source that included 50 people with overweight or obesity, researchers found that eating eggs and buttered toast for breakfast — instead of cereal, milk, and orange juice — increased the participants’ feelings of fullness for the next 4 hours.
Similarly, another studyTrusted Source involving 48 adults found that those who ate a breakfast containing protein from eggs, as well as high fiber foods, reported greater satiety (fullness) than those who ate low fiber cereal and milk.
Leafy greens
Leafy greens such as kale, spinach, and collard greens pack fiber and nutrients that can help keep you satisfied and hydrated.
What’s more, leafy greens contain thylakoids, plant compounds that have been linkedTrusted Source with increased satiety and better appetite management.3. Fish
Fish is loaded with high quality protein, healthy fats, and other important nutrients. That combination keeps you feeling full and can helpTrusted Source you manage your weight.
What’s more, fish — and seafood in general — may supply a significant amount of iodine, which is necessary for maintainingTrusted Source thyroid function and metabolism.
4. Cruciferous vegetables
Like other vegetables, cruciferous vegetables such as broccoli, cauliflower, and cabbage are high in fiber and tend to be incredibly filling.
5. Chicken breast and some lean meats
6. Potatoes and other root vegetables
7. Beans and legumes
8. Soups
9. Cottage cheese
