TOPIC 1B: Digestion, Absorption, & Metabolism Flashcards
The process of taking food, drink or another substance into the body by swallowing or absorbing.
Ingestion
The process by which substances passes through the intestinal mucosa into the blood or lymph.
Absorption
The process by which food are broken down into smaller units to prepare nutrients for absorption.
Digestion
A set of processes through which absorbed nutrients are used by the body for energy to form and maintain body structures and functions.
Metabolism
Amount of energy required to maintain life sustaining activities for a specific period.
Basal Metabolism
A semi liquid
mixture produced by churning and mixing of food mass with gastric juice.
Chyme
The chemical altering effects of digestive secretions, gastric juices and enzymes of food.
Chemical Digestion
The crushing and twisting effect of teeth and peristalsis that divide food into smaller particles.
Mechanical Digestion
Stimulates mechanical and chemical digestion. Produces saliva.
Mouth
Facilitates movement of food during mastication and assisting swallowing.
Mouth
Facilitated in eating and speaking.
Mouth
On the part of a mechanical digestion, the teeth plays a vital role of…
Tearing and Pulverizing Food
Assist in guiding food into chewing position bringing the pulverized food into the esophagus.
Tongue
It consists of taste buds for sensations of sweet, bitter, salty, and sour taste.
Tongue
It is where chemical and mechanical digestion took place to prepare nutrients for absorption.
Stomach
Where foods are hold for partial digestion. It produces gastric juice that provide acidity assisting effective functions of the enzyme.
Stomach
Muscular action tearing food into smaller particles through the help of gastric juices takes place.
Stomach
Creation of chyme is accomplished and kept in the…
Stomach
Main site of nutrient digestion and absorption.
Small Intestine
Breaks down food from the stomach and absorbs nutrients from the food.
Small Intestine
Hormones are produced. The bile that is secreted in the liver and stored in the gallbladder acts an emulsifier of fats.
Small Intestine
Organ for the formation and elimination of feces.
Large Intestine
It absorb water and salts from the material that has not been digested as food.
Large Intestine
Responsible for final absorption of any available nutrients like water and minerals.
Large Intestine
Absorption of electrolytes, vitamins and water from waste substances.
