Term | Definition |
---|---|
Osmosis | Osmosis is the movement of water molecules across a semi-permeable membrane from a region of high water concentration (or low solute concentration) to a region of low water concentration (or high solute concentration). |
Hypertonic | A solution pulling water away, shrinking cells, a reminder of imbalance. |
Isotonic | having equal tension |
Diffusion | The natural flow of particles, a quiet equalizer. |
Concentration Gradient | The invisible slope guiding molecules, from more to less, until balance is reached. |
Telemedicine / Telehealth | Healing at a distance — connecting lives through technology. |
Hormones | Messengers of the body, small but powerful, directing every rhythm of life. |
Metabolism | The fire within, breaking down and building up, sustaining every heartbeat. |
Cellular Respiration Equation | C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP — the formula of life’s energy. |
Reactant(s) | The beginning, the raw materials waiting to transform. |
Product(s) | The outcome, proof that change has taken place. |
Adenosine Triphosphate (ATP) | Life’s currency, powering every move, every breath, every thought. |
Diabetes Mellitus | when the body does not produce enough insulin, does not use insulin effectively, or both. |
Type 1 Diabetes | body's immune system mistakenly attacks and destroys the cells in the pancreas that produce insulin |
Type 2 Diabetes | does not produce enough insulin to regulate blood sugar levels. |
Gestational Diabetes | type of diabetes that develops during pregnancy in women who did not have diabetes before |
Hyperglycemia | Sugar in excess, threatening the body’s delicate balance. |
Hypoglycemia | The absence of sugar’s warmth, leaving weakness in its wake. |
Autoimmune Disorder | When the protector becomes the attacker — the body at war with itself. |
Organic Macromolecules / Biomolecules | essential organic compounds produced by living organisms, acting as the building blocks and functional components of life, including carbohydrates, lipids, nucleic acids, and proteins |
Carbohydrates | The quick spark of energy, the sweetness of life. |
Proteins | The builders and repairers, shaping every structure. |
Lipids | Silent reservoirs of energy, insulating and protecting. |
Nucleic Acids | The keepers of code, writing the story of life itself. |
Insulin | The key unlocking cells, allowing life to flow in. |
Glucose | Life’s simplest fuel, carried through every vein. |
Glucagon | The call to arms when sugar runs low — a signal for release. |
Negative Feedback Loop | The guardian of balance, bringing the body back to center. |
Positive Feedback Loop | The amplifier, pushing forward until a task is complete. |
Blood Glucose Meter (Glucometer) | the truth-teller, measuring life’s delicate balance. |
Continuous Glucose Monitor (CGM) | The silent watcher, guiding those who fight the sugar battle. |
Insulin Pump | A steady hand, delivering life drop by drop. |
Pancreas | The exocrine pancreas produces enzymes that help to digest food, particularly protein |
Alpha Cell | The releasers of glucagon, awakening the body in times of need. |
Beta Cell | The creators of insulin, unlocking life’s precious fuel. |
