Level of Organization

Models help understand internal body parts and functions.
Humans have many organ systems, including circulatory, respiratory, digestive, and excretory.
The heart is the circulatory system's central organ, acting as a pump to circulate blood.
Arteries carry oxygenated blood away from the heart, veins return deoxygenated blood.
Capillaries facilitate oxygen and nutrient exchange with cells.
Kidneys filter blood, removing waste and excess water.
Digestion breaks down food for nutrient absorption.
The brain controls organ functions.
Lungs facilitate breathing, taking in oxygen, and expelling carbon dioxide.

Organ Systems

Nervous System:
- Major Organs: Brain, spinal cord, nerves.
- Simple Function: Controls body activities, sending signals between brain and body parts.
Circulatory System:
- Major Organs: Heart, blood vessels (arteries, veins, capillaries).
- Simple Function: Transports blood, carrying oxygen, nutrients, and removing waste.
Respiratory System:
- Major Organs: Lungs, trachea, bronchi, diaphragm.
- Simple Function: Enables oxygen intake and carbon dioxide removal.
Digestive System:
- Major Organs: Mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, rectum, anus.
- Simple Function: Breaks down food, absorbs nutrients, eliminates waste.
Excretory System:
- Major Organs: Kidneys, bladder, ureters, urethra.
- Simple Function: Removes waste and excess substances from the body.
