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
