Study Notes

The text explains the journey of food in the digestive system, starting from the mouth where digestion begins with the breakdown of carbohydrates.
Chewing helps increase the surface area of the food for better chemical reactions, and saliva from salivary glands contains enzymes like amylase to start breaking down carbohydrates.
Swallowing food involves passing it through the pharynx to the esophagus, where peristaltic movements help move the food towards the stomach.
In the stomach, food is mixed with gastric juices containing hydrochloric acid (HCl) for protein digestion, with pepsin breaking down proteins into smaller molecules.
The partially digested food (chyme) then moves to the small intestine, where further digestion occurs with the help of pancreatic enzymes and bile produced by the liver to emulsify fats.
The small intestine is divided into the duodenum, jejunum, and ileum, with the absorption of nutrients mainly happening in the jejunum.
In the large intestine, water and minerals are absorbed, and the remaining waste forms into feces for elimination through the rectum.
