digestive systemWhat is digestion?

Digestion is the process of decomposing ingested foods into simple components that can be absorbed by the body to build and nourish cells and to get the energy needed for daily activities. It is accomplished by the secretions of various organs involved in digestion and motility (the activity of gastrointestinal system muscles of mixing and pushing food to the end of the digestive tract).

Absorption is the passage of nutrients, salts and water of the intestine into the blood or lymph through the gastrointestinal system epithelium.

Main components of the digestive system:

Mouth – Digestion starts in the mouth as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.
Throat – Throat makes the connection with the esophagus or swallowing tube.
Esophagus – His role is to carry food, liquids, and saliva from the mouth to the stomach.
Stomach – The stomach secretes acid and enzymes that digest food. The stomach muscles contract periodically, churning food to enhance digestion.
Small Intestine – The vast majority of digestive processes occur in the small intestine, among which the most important processes are:
– Decomposing fats into fatty acids
– Decomposition of complex carbohydrates into glucose
– Breakdown of peptide chains of proteins and transformation into simple amino acids
– Absorption of amino acids, fatty acids and glucose into the blood
Colon (Large Intestine) – His role is to absorb the remaining water and electrolytes from indigestible food matter; to accept and stores food remains that were not digested in the small intestine and to eliminate feces from the body.
