Hon A&P Flashcards
Physiology
Study of the body functions.
Anatomy
Study of the body structure.
Movement
The organism’s, cell’s, or organelles’ ability to move substances.
Responsiveness
The ability to detect and to respond to internal and external stimuli.
Growth
Growth in size OR number of cells.
Reproduction
New cells OR organisms produced.
Respiration
Releasing energy from foods.
Digestion
Breakdown of macromolecules.
Absorption
Moving materials through membranes into bodily fluids.
Assimilation
Changing absorbed materials into other compounds to be used in the body.
Nutrients
Nutrients are foods, vitamins, and minerals. They are used for cellular respiration, building blocks, and regulating chemical reactions.
Circulation
Moving substances throughout the body.
Excretion
Removing metabolic wastes.
Water
Water is used for transport, temperature regulation, and metabolism. Requires an aqueous environment.
Heat
Necessary for metabolism, temperature or amount of heat determines the rate of the chemical reaction.
Pressure
A certain amount of force is required for breathing (air pressure) and for pumping blood (blood pressure).
Oxygen
Used for cellular respiration.
Homeostasis
Maintaining a stable internal environment.
Some body’s homeostatic mechanisms
Temperature, blood sugar, blood pressure, fluid levels, blood ion levels, and oxygen levels.
Negative Feedback
An internal change that causes a response that reverses the original response. Body temp, and most body feedback mechanisms are examples of negative feedback.
Oral
Mouth
Positive Feedback
Rare; a response that enhances the original stimulus. Childbirth, induced labor, and blood clotting are examples of positive feedback.
Cranial
Houses the brain
Orbital
Eye sockets
Middle Ear

Nasal
Nose
Vertebral Canal
Houses the spinal cord
Abdominal
Stomach, liver, pancreas, intestines, etc.

Upper chest area cavity
Mediastinum

Cardiovascular and lymphatic
Skeletal
Bones, ligaments, and cartilage. Specific function is for framework and protection.
Muscular
Skeletal muscles. Specific function is contraction for movement.
Neurons
Brain, spinal cord, sense organs, and nerves. Specific function is to sense changes, send messages, and determine responses.
Endocrine
Glands; specific function is to send chemical messages.
Cardiovascular
Heart, blood, and vessels; specific function is to circulate materials back to cells.
Digestive
GI tract, liver, gallbladder, and pancreas; specific function is to break down and absorb nutrients.
Lymphatic
Lymph fluid, vessels, and nodes; specific function is to carry body fluids back to blood.
Respiratory
Lungs, bronchi, and trachea; specific function is to bring oxygen into blood and take carbon dioxide out of blood.
Posterior
Toward the back of body
Urinary
Kidneys, ureters, bladder, and urethra; specific function is to remove waste and excess water.
Integumentary
Skin; specific function is to keep outside and inside apart.
Ovaries and Testicles
To produce the next generation.
Inferior
