TermDefinition
ATP Energy molecule created in the mitochondria, by aerobic respiration-using oxygen to breakdown glucose
Pulse Rate blood pressure in an artery that measures the rate of blood flow
HIV/AIDS weakens/destroys one's immune system; t cells/memory cells are dystroyed
Cellular Respiration the process of breaking down glucose to release energy, ATP
Neurons single unit of the nervous system that transmits nerve impulses
What is the purpose of adjacent neurons? cell communication
spinal cord reflexes
Negative Feedback balance of hormone in the body; if one hormone is secreted, another is inhibited
Lungs excretes CO2 and water vapor
What molecules help to digest these polymers? enzymes
Nutrients Carbohydrates, Proteins, Lipids, Water, Minerals, Vitamins... necessary for maintaining life, providing energy, repairing damage, growing
Purpose of villi in the small intestine? increase surface area to absorb nutrients into the bloodstream
Blood transport medium that carries gases, nutrients, hormones, minerals to various body parts
What happens to 02? CO2? Levels in the blood during physical activity? O2 is used by muscles, so demand for O2 increases, and more CO2 is created, thus more demand to remove it.

Metabolism the process by which your body converts what you eat and drink into energy
Function of the Circulatory System transportation of dissolved ans suspended materials throughout the body
Function of Respiratory system supply the body with oxygen and dispose of carbon dioxide
Function of Nervous system secretes chemical messengers (neurotransmitters) across synapse
Why must polymers be digested? They are too big to fit through the cell membrane
Microbes/ Pathogen microorganism, virus, bacteria, any foreign invaders
Cerebellum responsible for coordination and balance
Homeostasis balance; dynamic equilibrium; maintaining a constant internal environment despite a changing external environment
Validity of an experimentDiabet doing an experiment more times than one can improve/ disprove one's results. Repeating increases validity
