Vitamin A is also necessary for proper skeletal and teeth development.
Digestion breaks down the massive, complex molecules that make up many nutrients into their simplest, most soluble forms, allowing the body to absorb and utilize them. This process involves two primary forms of action: mechanical digestion and chemical (or enzymatic) digestion. Mechanical digestion is the physical chewing, mixing, and flow of food through the gastrointestinal tract. Chemical digestion is the process of breaking down the chemical bonds of complex nutrients using an enzyme to catalyze the hydrolysis.
Fats, carbs, and proteins are the three main categories of nutrients that require digestion. Before absorption, the majority of the fat in meals is hydrolyzed into glycerol, free fatty acids (FFAs), and some monoglycerides and diglycerides. Complex carbs are broken down into simple sugars like glucose, galactose, and fructose. Protein molecules are hydrolyzed into single amino acid units and certain dipeptides. As dietary nutrients are digested, they are carried through the digestive tract via contractions of the gastrointestinal tract's muscular walls.
The process of digestion and absorption begins when food enters the mouth and finishes with the elimination of waste products and undigested food particles in the stool. Digestion and absorption begin in the mouth with food mastication (chewing) and saliva formation. Digestion continues throughout the gastrointestinal tract, culminating in the expulsion of waste products and undigested food particles in the feces.
In all species, the mouth brings food into the body, initiates physical mastication, and mixes it with saliva. Saliva is produced in reaction to the sight and smell of food. It functions as a lubricant, making chewing and swallowing easier, and it also solubilizes the dietary components that excite the taste buds and add flavor to foods.
Saliva is crucial for evaporative cooling in dogs (but less so in cats). Unlike many ruminant and herbivorous species, which completely masticate their food, dogs and cats sometimes swallow big boluses of food with little or no chewing. However, there are significant differences between dogs and cats. Although domesticated dogs and cats have the same number of incisor and canine teeth (six incisors and two canines on both top and bottom jaws), the dog's mouth has more premolars and molars than the cat's.

The word "vitamin A" refers to numerous similar chemical substances known as retinol, retinal, and retinoic acid. Of these compounds, retinol is the most physiologically active. Vitamin A serves multiple purposes in the body, including eyesight, bone formation, reproduction, and epithelial tissue upkeep. The effect of vitamin A in vision is widely understood.
Rhodopsin, often known as visual purple, is formed when retinal mixes with a protein called opsin in the retina's rod cells. Rhodopsin is a light-sensitive pigment that helps the eye adjust to variations in light intensity. When exposed to light, rhodopsin breaks into retinal and opsin, with the energy released causing nerve signals to the optic nerve.
In the dark, rhodopsin can be recreated by combining fresh retinal and opsin proteins. During periods of vitamin A insufficiency, less retinal is available to replenish rhodopsin, causing the eye's rods to become more sensitive to light fluctuations, eventually leading to night blindness. Vitamin A is also required for the creation and maintenance of normal epithelial tissue. This tissue includes the skin, as well as the mucous membranes that line the respiratory and gastrointestinal passages. Vitamin A is thought to be important for cell proliferation and differentiation, as well as the creation of mucoproteins present in the mucus generated by some types of epithelial cells.
Mucous secretions from epithelial tissue protect the epithelium from bacterial invasion. In the absence of vitamin A, new epithelial cells beyond the squamous type do not differentiate into mature mucus-secreting cells, and normal epithelial cells are replaced by defective, stratified, keratinized cells. When epithelial tissue fails to function properly, it causes epithelial lesions and increases infection susceptibility.

Vitamin A is also necessary for proper skeletal and teeth development, as well as reproductive performance. The vitamin's role in bone formation appears to be associated with the activities of epithelial cartilage osteoclasts and osteoblasts, as well as cellular division and membrane maintenance via glycoprotein production. Experiments with laboratory animals have demonstrated that vitamin A is also required for male spermatogenesis and female estrous cycles.
Plant cells generate carotenoids, which are the source of all vitamin A. Carotenoids are dark red pigments that give many plants their distinctive deep yellow/orange hue. Vegetables rich in these chemicals include carrots and sweet potatoes. These pigments are also present in deep green plants, but their color is obscured by chlorophyll's deep green hue. When animals absorb carotenoids from plants, the enzyme B-carotene 15,15' dioxygenase in the intestinal mucosa transforms them to active vitamin A.
The active vitamin is then absorbed and stored, primarily in the liver. Although various carotenoids can provide vitamin A, beta-carotene is the most common in foods and has the highest biological activity. Although animal products lack carotenoids, they can supply active vitamin A when consumed. Fish liver oils have the largest concentrations, but other frequent foods including milk, liver, and egg yolk also contain vitamin A.
