1. How does the food change in consistency and form?
- Food changes in consistency and form through processes like chewing, mixing with saliva, digestion in the stomach, and enzymatic breakdown in the intestines.
2. How could the body absorb the nutrients from the foods we eat?
- The body absorbs nutrients in the small intestine, where digested food is broken into simpler forms like glucose, amino acids, and fatty acids. Tiny structures called villi and microvilli increase the surface area for absorption, allowing water-soluble nutrients to enter the bloodstream and fat-soluble nutrients to pass through the lymphatic system. These nutrients are then transported to support energy, growth, and tissue repair.
