Study Notes
Human Body Organization
- Cells are organized into tissues.
- Tissues are organized into organs.
- Organs are organized into systems.
- Systems work together to form an organism.
Necessary Life Functions
- Respiration: Taking in oxygen and releasing carbon dioxide.
- Digestion: Breaking down food into usable nutrients.
- Excretion: Removing waste products from the body.
- Movement: Locomotion, propulsion, and contractility.
- Responsiveness: Sensing and responding to changes in the environment.
- Metabolism: All chemical reactions in the body.
- Reproduction: Cellular and organismal reproduction.
- Growth: Increase in size of body parts or the entire organism.
Organ Systems
- Integumentary: Forms external covering, protects, and synthesizes vitamin D.
- Skeletal: Supports and protects organs and forms framework for muscles.
- Muscular: Movement and posture, produces heat.
- Cardiovascular: Transports nutrients and oxygen via the heart and blood vessels.
- Lymphatic: Removes fluid from tissues and returns to blood, houses immunity cells, disposes of debris.
- Respiratory: Takes in oxygen and removes carbon dioxide.
- Digestive: Breaks down food into absorbable units.
- Endocrine: Controls long-term processes like growth and fluid balance.
- Urinary: Removes metabolic wastes.
- Nervous: Fast-acting control system, responds to stimuli.
- Reproductive: Involved in reproduction.
Cellular Respiration and Energy
- Glucose and oxygen are used to produce energy in mitochondria.
- Carbon dioxide and water are waste products.
- ATP (adenosine triphosphate) stores energy for cellular activities.
- Body systems work together to provide food, oxygen, and remove waste.
