|---|---|
| Organelles | Subcellular structures with specific functions in a cell. |
| Cell | The smallest unit of life responsible for all life functions. |
| Nucleus | The organelle that stores genetic information. |
| Mitochondria | The organelle that produces chemical energy for the cell. |
| Ribosomes | The organelles that assemble proteins in the cell. |
| Tissues | Groups of cells that work together to perform specific functions in the body. |
| Excretion | The process of removing waste products and excess water from the body. |
| Positive Feedback | A process in which changes cause additional similar changes, leading to unstable conditions. ex: giving birth, blood clots, lactation |
| Negative Feedback | Mechanisms that restore the level of a biochemical in the environment to its normal range. ex: insulin decreases blood sugar |
| Homeostasis | The dynamic state in which the body's internal environment is maintained within a normal range. |
| Life | Living organisms respond to their surroundings, grow, reproduce, are responsive, move, and have metabolism. |
| Growth | The increase in cell number and size, resulting in an increase in body size. |
| Reproduction | The production of new cells and organisms. |
| Responsiveness | The reaction to a change inside or outside of the body. |
| Movement | The change in body position or location, as well as the motion of internal organs. |
| Metabolism | The sum of all chemical reactions in a living system, including energy and nutrient cycling. |
| Respiration | The process of acquiring energy by taking in oxygen and releasing carbon dioxide. |
| Digestion | The process of breaking down food into usable nutrients for absorption into the blood. |
| Circulation | The movement of chemicals and cells through the body fluids. |
| Water | The most abundant chemical in living systems, required for metabolic processes and organ function. |
| Cell Death | The process in which cells reach the end of their lifespan and undergo predetermined cell death. |
| Parietal Pleura | The serous membrane lining the cavity of the lungs. |
| Visceral Pleura | The serous membrane covering the surface of the lungs. |

| Lymphatic System | The system responsible for immune responses and fluid balance in the body. |
| Muscular System | The system of muscles enabling movement and generating heat. |
| Digestive System | The system responsible for breaking down food and absorbing nutrients. |
| Nervous System | The system controlling and coordinating body functions through electrical signals. |
| Respiratory System | The system responsible for oxygen intake and carbon dioxide removal. |
| Urinary System | The system responsible for filtering blood and eliminating waste through urine. |
| Cardiovascular System | The system responsible for transporting blood, nutrients, and oxygen throughout the body. |
| Reproductive System | The system responsible for producing offspring. |
| Abdominal Pelvic Regions | The regions of the abdomen and pelvis where specific organs are found. |
| Cavities in the Head | The cranial, frontal, oral, sphenoidal, nasal, and orbital cavities in the head. |
| Sections | The frontal, transverse, and sagittal sections used to divide the body for study. |
| Assimilation | the process of absorbing nutrients during digestion and distributing them to the body for growth and repair |
| Life and their Characteristics | Growth, reproduction, responsiveness, movement, metabolism, respiration, digestion, circulation, & excretion. |
| Centenarians characteristics | genetics, healthy lifestyle, positive outlook, social connections, adaptability, stress management, moderate diet, continued learning, regular physical activity, stress management, adaptability |
| Wrinkling and sagging skin | with aging the skin naturally becomes less elastic and drier, with less fat and collagen in the deeper layers. |
