Digestion
Digestion
The process of breaking down food into smaller molecules that can be absorbed by the body.
Anaerobic respiration
Anaerobic respiration
A type of respiration that occurs in the absence of oxygen and produces lactic acid as a byproduct.
Open system
Open system
A system that allows the exchange of both matter and energy with its surroundings.

Physical Activity and Body Changes
- Increased Body Temperature: Respiration (releasing energy) elevates body temperature.
- Elevated Heart Rate: Increased heart rate pumps more blood, delivering nutrients and oxygen needed for respiration.
- Deeper Breathing: More oxygen intake occurs for enhanced respiration.
- Muscle Soreness: Anaerobic respiration produces lactic acid, causing muscle ache.
- Shortness of Breath: Faster breathing, more oxygen intake.
- Sweating: Cools the body.
- Increased Blood Pressure: Delivers oxygen and nutrients to muscles and organs.
Systems
- System: An arrangement or class of objects or entities. Living things can also be considered as systems.
- Open System: Exchanges matter and energy.
- Examples: Open containers; human beings
- Closed System: Exchanges energy only.
- Examples: Closed containers. This transfer can be heat energy.
- Isolated System: Neither matter nor energy is exchanged.
- Example: The theoretical universe.
Emergent Properties
- Emergent Properties: Features arising from interacting parts of a system, not inherent to individual parts.
- Hierarchy: A ranking system based on status or authority within an organization.
- System Interactions: The ways components of a body's systems work together.
- Examples: Digestive, Cardiovascular, Respiratory Systems
- How nutrients and oxygen reach the bloodstream: The body depends on interconnected organ systems
Biological Molecules
- CHON: The four main elements in all living things: Carbon, Hydrogen, Oxygen, and Nitrogen.
