foundations of body
| Term | Definition |
|---|---|
| body cavities | where internal organs are housed |
| posterior (dorsal) | back or upper side, cranial and vertebral cavities |
| ventral | front of body, thoracic and abdominopelvic cavities |
| serous membrane | 2 types of two layered membranes |
| parietal | wallpaper, lines internal surface of bodywall |
| visceral | covers external surface of organ |
| serous cavity | space between parietal and visceral filled with serous fluid, reduces friction |
| pericardium | 2 layered serous membrane around heart, visceral peri, parietal peri, peri cavity (fluid) |
| pleura | 2 layered serous membrane around the lungs, parietal pleura, visceral pleura, pleural cavity |
| peritoneum | 2 layered serous membrane around abdominopelvic, parietal perit, visceral perit, peritoneal cavity |
| homeostasis components | receptors: detector control center: interpretor effector: changer |
| negative feedback | brings back to set points |
| positive feedback | boosts stimulus |
| Mediastinum | median space in the thoracic cavity |
| homeostasis process | recepter, control center, effector |
| avascular | without blood supply |
| mucus membrane | lines compartments that open to external environments |
| cutaneous membrane | know as skin |
| synovial membrane | lines some joints and secretes synovial fluid |
| Which feedback mechanism is responsible for stabilizing body systems? | negative feedback |
| What is the role of homeostasis in living organisms? | To maintain stable internal conditions |
| What is the primary focus of physiology within anatomy and physiology studies? | To examine how the body functions |
| Which research method involves the use of statistical analysis to assess data? | Quantitative research |
| Organ | A structure composed of two or more tissue types that performs a specific function |
| Tissue | Group of cells that work together to perform a specific function |
| Cell | The basic unit of life |
| Molecule | Two or more atoms bonded together |
| What is the main difference between the parietal and visceral layers of serous membranes? | Parietal lines the body wall, visceral covers organs |
| Which of the following layers of serous membranes covers the organs in the abdominal cavity? | Visceral peritoneum |
| Which level of organization represents the basic unit of life? | Cellular level |
| In which part of the body cavities are the lungs located? | Thoracic cavity |
