What we have learnt
- The human digestive system processes food through mechanical and chemical means, emphasizing the role of enzymes.
- The heart and blood vessels work together in a sophisticated circulatory system, ensuring efficient transport of oxygen and nutrients.
- The immune system employs various defenses against pathogens, including physical barriers and specialized cells.
Key Concepts
- -- Mechanical Digestion
- The physical process of breaking down food into smaller pieces to facilitate enzyme action.
- -- Chemical Digestion
- The enzymatic breakdown of macromolecules into absorbable units such as carbohydrates, proteins, and lipids.
- -- Homeostasis
- The maintenance of a stable internal environment, regulated through various feedback mechanisms.
- -- Antibody Production
- The process by which B cells produce antibodies upon exposure to antigens to neutralize pathogens.
- -- Sliding Filament Theory
- The mechanism of muscle contraction, where actin and myosin filaments slide past each other within the sarcomere.
