Animal nutrition focuses on the dietary needs of domesticatedanimals, primarily those in agriculture and food production. There are seven major classes of nutrients: carbohydrates, fats, fibre, minerals, protein, vitamin, and water.
The process by which food is broken down into simple chemical compounds that can be absorbed and used as nutrients or eliminated by the body.
Buccal cavity is the portion of the oral cavity bounded by the lips, cheeks, and gums. It also called vestibule of mouth.
Oesophagus is the part of the alimentary canal which connects the throat to the stomach. In humans and other vertebrates it is a muscular tube lined with mucous membrane.
Stomach is the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the oesophagus to the small intestine.
Small intestine is the part of the intestine that runs between the stomach and the large intestine.
Large intestine is the lower part of the bowels in which water is removed from digested food before it is passed out of the body as solid waste.
Anus is the opening at the end of the alimentary canal through which solid waste matter leaves the body.
Alimentary system is the whole passage along which food passes through the body from mouth to anus during digestion.
Digestive system is the system by which ingested food is acted upon by physical and chemical means to provide the body with absorbable nutrients and to excrete waste products.
Milk tooth is any of a set of early, temporary (deciduous) teeth in children or young mammals which fall out as the permanent teeth emerge (in children between the ages of about six and twelve).
A permanent tooth is a tooth in a mammal that replaces a temporary milk tooth and lasts for most of the mammal's life.
Ingestion is the the process of taking food, drink, or another substance into the body by swallowing or absorbing it.
Saliva is the watery liquid secreted into the mouth by glands, providing lubrication for chewing and swallowing, and aiding digestion.
Starch is an odourless, tasteless white substance occurring widely in plant tissue and obtained chiefly from cereals and potatoes. It is a polysaccharide which functions as a carbohydrate store and is an important constituent of the human diet.
Protein is any of a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.
Bile juice is a digestive juice made by the liver and stored in the gall bladder.
Gall bladder is the small sac-shaped organ beneath the liver, in which bile is stored after secretion by the liver and before release into the intestine.
Absorption is the movement of a substance, such as a liquid or solute, across a cell membrane by means of diffusion or osmosis.
Villi are minute projections arising from a mucous membrane, especially in the numerous vascular projections of the small intestine.
Assimilation is the combination of two processes to supply cells with nutrients.
Cud is partially digested food regurgitated from the first stomach of cattle and other ruminants to the mouth for a second chewing.
Rumination is The act or process of ruminating, or chewing the cud.
Ruminants are Any of various hoofed, usually horned mammals, such as cattle, sheep, and goats, that have an even number of toes. Ruminants have a stomach divided into four compartments and chew a cud consisting of regurgitated, partially digested food.
Cellulose an insoluble substance which is the main constituent of plant cell walls and of vegetable fibres such as cotton. It is a polysaccharide consisting of chains of glucose monomers.
Amoeba is a single celled independent organism.
Pseudopodia are temporary cytoplasmic projections of the cell membrane in certain unicellular organisms such as amoeba. Pseudopodia literally means false foot. That is because they are associated with the motion of the organism.
Food vacuole is a membrane-bound vacuole (as in an amoeba) in which ingested food is digested.
