In "Rohit Sir’s" style, here is the high-impact summary of stomach digestion: The stomach is a J-shaped muscular bag where food is transformed into a semi-liquid paste called chyme. This happens through two main actions: Mechanical: The stomach walls churn and grind food, mixing it thoroughly with enzymes. Chemical: Gastric glands secrete HCl, which kills bacteria and activates Pepsin. Pepsin then begins the crucial task of breaking down proteins into smaller peptides. Mucus acts as a shield, protecting the stomach lining from the strong acid. Key takeaway: Digestion here is mainly about protein breakdown and disinfection.
