Digestion and Absorption in One Shot - NEET/Class 11th Boards
PW English Medium・2 minutes read
Human physiology covers various body systems, with the first chapter focusing on nutrition, the process of ingesting food for energy production through digestion and absorption. The text delves into the details of how ingestion, digestion, absorption, assimilation, and egestion work in human nutrition, highlighting the importance of enzymes, glands, organs like the stomach, liver, pancreas, and small intestine, and common issues like malnutrition, jaundice, and indigestion.
Insights
- Human physiology focuses on digestion, absorption, and nutrition, where ingested food is broken down into simpler forms for energy production.
- Teeth play a crucial role in digestion, with different types like incisors, canines, premolars, and molars serving distinct functions in chewing and grinding food.
- The pancreas is a vital organ in digestion, producing enzymes like lipase, amylase, and nucleases for breaking down lipids, starches, and nucleic acids.
- Absorption in the gut involves various mechanisms like simple diffusion, facilitated transport, and active transport for different nutrients, with the small intestine being the primary site for absorption.
