Important Topics for NCERT Biology Exemplar Solutions Class 11 Chapter 16 – Digestion and Absorption
Digestion is the method of breakage of large, unsolvable food molecules into smaller molecules for their absorption into the bloodstream. Digestion initiates in the mouth and endures as food travels through the small intestine.
Types of Digestion
Digestion is generally classified into two types:
- Mechanical Digestion: It comprises the breakage of large food molecules into smaller ones.
- Chemical Digestion: It consists of the breakdown of difficult food molecules into small ones in the existence of the digestive enzyme.
Absorption is the procedure of assimilating materials into the cells or across the tissues and organs through the method of diffusion or osmosis. Absorption happens in the small intestine.
The Alimentary Canal
The alimentary canal is the complete channel along which the consumed food is broken down into its elements and are absorbed for use by the body. When all the constituents of the gastrointestinal tract are stretched out, end to end, it unevenly calculates 30 feet or about 9 meters. The constituents are as follows:
- Oral cavity
- Small intestine
- Large intestine
Accessory Organs of the Digestive System
Besides the organs in the gastrointestinal tract, there are some additional organs and glands that are not directly a part of the digestive system but they offer critical functions that help in digestion, absorption or break down of food. These are named as the accessory organs of the digestive system.
Disorders of the Digestive System
Some of the disorders of the digestive system include:
- Stomach Flu
- Irritable Bowel Syndrome (IBS)
- Inflammatory Bowel Disease (IBD)
- Gluten Sensitivity and Celiac Disease
- Gastroesophageal Reflux Disease (GERD)
- Peptic Ulcer Disease (PUD) and Gastritis
The human digestive system contains the gastrointestinal tract in addition to the accessory organs of digestion. Digestion includes the breakdown of food into smaller and smaller constituents until they can be absorbed and integrated into the body.
