| 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. |
