| A | B |
|---|
| Anatomy | Science that deals with the structure of the human body |
| Physiology | Science that deals with how the body functions |
| Gross Anatomy | Studying anatomy at a larger level, that which is visible to the human eye |
| Microscopic Anatomy | Studying of microscopic structures, such as the cells and tissue |
| Cytology | The study of cells |
| Histology | The study of tissues |
| 3 types of blood cells | Red, white & platelets. |
| Red Blood Cells | Carry oxygen |
| White Blood Cells | Defense |
| Platelets | Cause clotting |
| Tissues | A group of cells with similar structure and function |
| Metabolism | Sum total of all chemical reactions in the body |
| Differentiation | A property by which an undifferentiated cell changes into a differentiated cell |
| Undifferentiated Cell | Do not have a specific function, e.g. stem cells can form RBC, WBC and platelets |
| Differentiated Cell | Has a specific function, e.g. RBC, WBC, Platelets |
| Responsiveness | The ability to respond to both external and internal environment |
| Cells | The basic structural and functional units of life |
| Catabolism | Breakdown reaction. Process in which living cells break down subtances into simpler substances |
| Anabolism | Synthesis reaction. Simpler substances are combined to form more complex substances |
| Homeostasis | Maintaining a stable or constancy in the bodies internal environment |
| Negative feedback loops | The response reverses the stimulus. eg. Body temp. |
| Positive feedback loops | The response intensifies the stimulus. eg. Labor contractions |
| Serous membrane | Lines the body cavities |
| Viceral Layer of the serous membrane | Surrounds the organs |
| Parietal layer of the serous membrane | Outer wall, lines the body cavity |
| Pericardium | Serous membrane that surrounds the heart |
| Pleura | Serous membrane that surrounds the lungs |
| Peritonium | Serous membrane that surrounds the abdomino-pelvic organs |
