Bio Chapter One
| Question | Answer |
|---|---|
| Anatomy | Study of the structural basis of body function |
| Physiology | Study of the functional relevance of human structure |
| Anatomy and physiology | Highly interdependent and complementary |
| Subatomic Particles: | protons, neutrons, and electrons that make up cells |
| Atom: | tiny particles that make up chemicals (hydrogen, carbon) |
| Molecule: | particles consisting of atoms joined together (water, glucose) |
| Macromolecule | large particles consisting of molecules (D N A, protein) |
| Organelle | functional part of a cell (mitochondrion, lysosome) |
| Cells | basic unit of structure and functions (muscle, nerve, or blood cell) |
| Tissue | layer or mass of cells with specific function (adipose tissue) |
| Organ | group of different tissues with a function (heart, kidney, stomach) |
| Organ System | group of organs with common function (digestive system) |
| Organism | composed of organ systems interacting (human) |
| (Skin , hair , nails ) Integumentary System: | Body covering, protection, body temperature regulation, sensory reception, production of Vitamin D |
| Skeletal System: | Support and movement, framework |
| Muscular System: | Support and movement, main source of body heat |
| Nervous System: Integration and coordination of organ | function through nerve impulses and neurotransmitters |
| Endocrine system: Integration and coordination of organ | through chemical messengers called hormones |
| Cardiovascular System: | Transportation |
| Lymphatic System: | defends body against infection |
| Digestive System: | breaks down food, absorbs digestion products |
| Respiratory System: | Moves air in and out of body, exchanges gases (oxygen and carbon dioxide) |
| Urinary System: | regulates electrolyte & water balance |
| Reproductive System: | produce new like organisms. |
| Homeostais | any self-regulating process by which biological systems tend to maintain stability |
| Negative Feedback and Stability | body activates mechanisms that reverse it |
| Positive Feedback | Produce unstable conditions |
| Axial | portion: head, neck, and trunk |
| Appendicular | portion: upper and lower limbs |
| double-layered consist of visceral and parietal | |
| Visceral layer: inner layer | |
| outer layer, | |
| Cavity | in between |
| pluera | lungs |
| pericardium | heart |
| visceral peritoneum | covers and closer to the abdominal organs |
| START AT SLIDE 33 |
