true and false​

Answer 1

Answer:

Food digestion is the breakdown of large food particles into smaller absorbable nutrients needed for energy production, growth, and cellular repair. It begins with ingestion and ends with defecation. Digestion takes place in the gastrointestinal tract in two principal forms: mechanical and chemical. Mechanical digestion is the physical degradation of large food particles into smaller pieces that digestive enzymes can access through chemical digestion. Chemical digestion is the enzymatic cleavage of proteins, carbohydrates, and fats into tiny amino acids, sugars, and fatty acids. Once food enters the mouth, it mixes with saliva and gets chewed through the process of mastication. Saliva is rich in mucus and salivary enzymes, and together, with the effects of mastication, it creates a mass called a food bolus. The food bolus then travels down the esophagus via wave-like muscular contractions, called peristalsis, before it reaches the stomach.
