Key Functions in Human Biology

Digestive and Metabolic Functions

1. Saliva and Stomach Acid

  • Saliva: Lubricates food for swallowing, moistens the mouth, and contains the enzyme Salivary Amylase (Ptyalin) which begins the digestion of carbohydrates (starches).
  • HCl (Hydrochloric Acid): Maintains an acidic pH (1.5–3.5) in the stomach to activate pepsinogen into pepsin (for protein digestion) and kills ingested bacteria/microbes.

2. Basal Metabolic Rate (BMR)

  • BMR: The minimum amount of energy (calories) required by the body to maintain

This influence can be positive (transfer of skills) or negative (interference or fossilization).

Learners must develop not only linguistic competence but also academic language and the ability
