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.
