Human digestive system...!


¶¶¶ MOUTH ( teeth - chewing and grinding of food)
( tongue - rolling and tasting of food)

Salivary glands : secrete SALIVA AMYLASE < change="" starch="" into="" sugar="" />


¶¶¶ OESOPHAGUS ( takes food from mouth to oesophagus by PERISTALSIS movements { contraction n expansion of alimentary canal.}>>>)


¶¶¶ STOMACH. gastric juices


> pepsin - breaks down Protein
> HCl - makes medium acidic
> mucus - protects inner lining of stocmach


¶¶¶ SMALL INTESTINE. [ liver scretes bile]
[ pancreas sceretes pancreatic juice]


intestinal enzymes converts....* carbohydrates into glucose
* fats into fatty acids or glycerol
* protein into amino acid

¶¶¶ LARGE INTESTINE ( absorbs excess water )


¶¶¶ RECTUM ( temporary collection of waste)

¶¶¶ ANUS ( helps in egestion)

The Human Digestive System

The human digestive system is a complex network of organs and processes that are responsible for breaking down food into nutrients and waste products. The system includes several organs, including the mouth, esophagus, stomach, small intestine, large intestine, and anus.

Mouth and Esophagus

The digestive process begins in the mouth, where food is broken down by the teeth and saliva. The saliva contains digestive enzymes, which help to break down carbohydrates and other nutrients. The food is then swallowed and travels down the esophagus, a muscular tube that connects the mouth to the stomach.

Stomach

The stomach is a muscular sac that mixes the food with digestive juices, including hydrochloric acid and enzymes. This mixture, known as chyme, is then slowly released into the small intestine.

Small Intestine

The small intestine is a long, narrow tube that is about 20 feet long. It is responsible for the majority of nutrient absorption and contains several specialized structures, including the duodenum, jejunum, and ileum. The walls of the small intestine are lined with tiny finger-like projections called villi, which increase the surface area for absorption.

Large Intestine

The large intestine, also known as the colon, is a wider tube that is about 5 feet long. Its primary function is to absorb water and electrolytes from the remaining food matter, forming feces.

Anus

The anus is the opening at the end of the digestive tract, through which feces are expelled from the body during defecation.

Overall, the human digestive system is a complex and highly regulated process that is essential for the absorption of nutrients and elimination of waste products. Proper diet and lifestyle habits are important for maintaining digestive health and preventing digestive disorders.
