It has gotten views and also has rating/5(). 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 certain organisms, these smaller substances are absorbed through the small intestine into the blood ion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and MeSH: D

Jennings. The subject is treated here from a zoological rather than a biochemical aspect and the emphasis is on feeding mechanisms and digestive systems ranging from those of protozoa to those of mammals.

Cited by: Digestion is the process of modifying and/or hydrolyzing feed and food polymers into molecules and elements that can be absorbed across the intestinal wall.

Understanding of the digestive physiology of fish is a field still in its by: tion (swallowing), and the digestion, absorption, and assimilation of those food elements that are of nutritive value; and terminates with defecation, or the excretion of the remaining ingested matter not capable of being absorbed or utilized as nourishment.

To perform these functions, the digestive tract of the animal is equipped withFile Size: 1MB. The digestive process whereby animals reduce their food into a form in which it is readily available to their tissues is basically the same throughout the animal kingdom and consists of the progressive hydrolysis of proteins, carbohydrates and fats into the simpler.

Certain arthropods feed exclusively on fluids. Some animals feed on food masses, and they usually have organs for seizing, chewing, and consuming food. Herbivores are animals that eat only plants, while carnivores are animals that eat only other animals.

Omnivores, which consume both plants and animals, are typified by humans. The Digestion and Assimilation of Fat in the Human Body: An Epitome of Laboratory Notes on Physiological and Chemical Experiments Bearing on this Subject Medical tracts ; 48, no.

The process of digestion is different in human, grass eating animals, amoeba, etc. Absorption: The process of passing of digested food into blood vessels in the intestine is called the absorption.

Assimilation: The conversion of absorbed food in complex substances such as proteins and vitamins required by body is called assimilation.

They must then be broken down into smaller ones by digestive enzymes - digestion, before they can be taken from the gut into the blood stream - absorption. The cells of the body can then use these small molecules - assimilation.

The indigestible waste products are eliminated from the body by the act of egestion (see diagram ). The digestion process in Ruminants begins by chewing and swallowing its food. Ruminants do not completely chew the food they eat, but just consume or gulp as much they can and then swallow the food.

This is actually an adaptation by which these animals have evolved to spend as little time as possible feeding so that they are not hunted down by. The digestive system varies from the lower organisms such as amoeba and paramecium when compared to other higher-order animals such as fishes, amphibians, humans etc.

Human Digestive System. One important aspect of nutrition in animals is the digestion of food. how the nutrition in animals functions.

Digestion occurs when the animal’s body gets busy breaking down the food. Two types of digestion exist in all animals: Mechanical digestion physically breaks down food into smaller and smaller pieces. It begins when an animal consumes the food and continues until the food.

When food is processed in a book and abomasum, it enters the intestines, and from them is excreted through the anus. In a calf, the digestion process is the same as in monogastric animals. Gastrointestinal tract. The digestive system of cows is arranged in such a way that after chewing food turns to the throat.

Nutrition in Animals. Nutrition in animals depends upon the feeding habits of the animals. The process of taking in food is called ingestion. The method of ingestion is different in different animals. For example-Bees and hummingbirds suck nectar from plants, python swallows its prey and cattle feed on grass.

Different feeding habits of animals. The digestive system uses mechanical and chemical methods to break food down into nutrient molecules that can be absorbed into the blood. Once in the blood, the food molecules are routed to every cell in the animal's body.

There are two types of animal body plans as well as two locations fordigestion to occur. Sac-like plans are found in many. Digestion is the breakdown of carbohydrates, proteins and fats into small soluble substances to be absorbed into the blood.

Amylase, proteases and lipases are enzymes that are important in digestion. Excellent account of feeding mechanisms in animals. Magee, D. and A. Dalley, II. Digestion and the structure and function of the gut. Assimilation in the digestive system is the process by which nutrients from foods are taken into the cells of the body after the food has been digested and absorbed, according to IvyRose Holistic.

There are four basic stages of the digestive system process. The first stage is ingestion, and it is the process by which food is taken into the body. Animal nutrition focuses on the dietary needs of animals primarily those in agriculture and food production. One of the most crucial programs for animals is ensuring that they have water, energy, protein, minerals and vitamins to maintain body weight.
