    Peristalsis

    Wave-like muscular contractions that move food through the digestive tract.

    Enzymes

    Proteins that speed up chemical reactions in the body, like breaking down food during digestion.

    Amylase

    An enzyme found in saliva that breaks down carbohydrates into sugars.

    Study Notes

    Anatomy of the Digestive System

    • Mouth: Chews food and mixes it with amylase, initiating carbohydrate breakdown.
    • Esophagus: Peristalsis moves bolus (chewed food) to the stomach.
    • Stomach: Bolus mixes with gastric juices to form chyme.
    • Small Intestine: Pancreatic enzymes and bile break down food; villi absorb nutrients.
    • Large Intestine: Absorbs water and electrolytes; fiber moves the waste.
    • Rectum/Anus: Stores and eliminates waste.

    Key Digestive Terms

    • Peristalsis: Wave-like muscular movement pushing food through the digestive tract.
    • Enzymes: Proteins that speed up chemical reactions, like breaking down food.
    • Amylase: Enzyme that breaks down carbohydrates into sugars.
    • Bolus: Chewed, softened food ready for swallowing.
    • Nutrients: Substances in food that provide energy and support bodily functions.
    • Microbiome: Trillions of microorganisms living in the body, aiding digestion.
    • Bile: Liver-produced fluid, stored in the gallbladder, aiding fat breakdown.

    Caloric Content of Food

    • Calories: Measure of energy provided by food.
    • Carbohydrates: Main nutrient source for calories.

    Photosynthesis

    • Photosynthesis: Plants use sunlight, water, and CO2 to produce glucose (food) and release oxygen.
    • Light Absorption: Chlorophyll absorbs sunlight.
    • Water Absorption: Roots absorb water from soil.
    • Oxygen Production: Water is split into oxygen and hydrogen.
    • Glucose Formation: Sunlight, water, and CO2 are used to create glucose.
    • Oxygen Release: Oxygen is a byproduct of photosynthesis.

    Circular Economy

    • Circular Economy: Focuses on reducing material use through reuse, recycling, repairing, and reducing.

    Big Bang Theory

    • Big Bang Theory: A scientific theory proposing the universe originated from a massive explosion.

    Environmental Factors

    • Abiotic Factors: Non-living components of an environment (sunlight, water, temperature, soil).
    • Biotic Factors: Living components of an environment (plants, animals, microorganisms).

    Chemical Hazard Symbols

    • Triangle Symbol: Indicates a hazard; exposure can cause injury.
    • Octagon Symbol: Indicates potentially dangerous contents.
    • Caution: Temporary injury possible; death with extreme exposure.
    • Danger: Temporary or permanent injury or death possible.
    • Extreme Danger: Very low exposure can cause injury or death.

    States of Matter

    • Solid: Tightly packed particles vibrating in place, fixed shape and volume.
    • Liquid: Less tightly packed particles, able to flow, fixed volume but no fixed shape.
    • Gas: Particles move freely, taking the shape and volume of their container.

    Biodiversity and Sustainability

    • Sustainability: Maintaining a balance in the environment.
    • Resource Disruptions: Disrupting resources makes life unsustainable.
    • Human Impact Example: Human impact on the Great Lakes shows the need for pollution reduction to protect ecosystems.

    Chemical Formulas

    • Water: H₂O
    • Carbon Dioxide: CO₂
    • Nitrogen Molecule: N₂
    • Oxygen: O₂
