Digestive System
Breaks down food into nutrients
Muscular System
Helps the body move/maintains posture/produces heat
Skeletal System
Protect and support the body organs/stores minerals/provides a framework the muscles use to cause movement
Integumentary System
forms the body’s external coverings; helps to regulate body temperature
Urinary System
Rids the body of wastes/ regulates water balance of the blood
What are the Levels of organization ( from from smallest to largest)?
cells, tissue, organs, organ systems, organism
Biomedical Science
The application of science, especially biology and physiology, to clinical medicine.
Cause of Death
The Specific injury, trauma or disease that directly caused the victim’s eath
Mechanism of Death
What happens physiologically (inside the body) to result in death.
