Study of structure and shape of body and parts
Anatomy
reverse
Study of how the body and its parts work and function
Physiology

Integumentary Skin Skeletal Muscular Nervous Endochrine Cardiocvascular Lymphatic Respiratory Digestive Urinary Reproductive
Organ System
reverse
forms the external body covering protects deeper tissue from injury helps regulate body temperature loacation of cutaneous receptors sweat and oil glands
Integumentary Skin
reverse
protects and supports body organisms provides muscle attachment for movement site of blood cell formation stores minerals
Skeletal system
reverse
produces movement maintains posture produces heat
Muscular System
reverse
fast acting system responds to internal and external change activates muscles and glands
Nervous System
reverse
slow acting systems secretes regulatory hormones growth reproduction metablolism
Endocrine System
reverse
transports materials in body via blood pumped by heart oxygen, carbon, dioxide, nutrients, wastes
Cardiovascular System
reverse
returns fluids to blood vessels cleanses the blood involved in immunity
Lymphatic system
reverse
keeps blood supplied with oxygen removes carbon dioxide
Respiratory system
reverse
breaks down food allows for nutrient absorption into blood eliminates indigestible material
Digestive System
reverse
eliminates nitrogenous wastes maintains acid base balance regulates water and electrolytes
Urinary System
reverse
produces offspring testes produce sperm Ovaries produce eggs
Reproductive System
reverse
Maintain boundaries Movement Responsiveness Digestion metabolism Excretion Reproduction Growth
Functions for Life
reverse
Internal environment is different from external integumentary system keeps fluid in bacteria out protects agains sun heat and chemicals
Maintain Boundaries
reverse
locomotion walking swimming facial expression movement of substances food and waste through alimentary canal blood urine
Movement
reverse
ability to sense changes and react
Responsiveness
reverse
break down and absorption of nutrients
Digestion
reverse
all chemical reactoins in body breakdown complex molecules to smaller build smaller to larger produce energy make body structures
Metabolism
reverse
removing wastes produced during metabolic reactions and digestion primarily removed in urine and feces
Excretion
