Human Physiology
| Term | Definition |
|---|---|
| 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. |
| Vaccine | weakened/dead virus given to prepare one's immune system, by creating antibodies against that specific virus if infected in the future |
| Antibodies | a blood protein, produced to counteract a specific antigen |
| Allergy | an overreaction to a normally harmless protein |
| T-cells | memory cells; WBC that "remembers" a specific antigen, and if infected later in life, will not allow you to get sick a second time |
| High Blood Pressure | caused by factors such as, overweight, age, smoking, stress, genetics |
| Path of air from the atmosphere into lungs | nose, pharynx, trachea, bronchi, bronchioles, alveoli |
| Receptor molecules | receive the chemical message from the adjacent cell; shape must fit |
| Diabetes | the inability of the pancreas to release insulin/glucagon to regulate blood sugar levels Validity of an experiment doing an experiment more times than one can improve/ disprove one's results. Repeating increases validity |
| Kidneys | filters the blood to reabsorb the good and get rid of the bad (urine) |
| Cytoplasm | responsible for cell metabolism and transportation w/cell |
| 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 |
