Intro to Anatomy
Body systems
| Question | Answer |
|---|---|
| Describe Anatomy | The study of the structure of body parts and their relationships to one another. they can be felt, seen and examined. |
| Describe Physiology | Concerns the functioning of the body's structural machinery and how the parts of the body work. |
| What is Gross/Macroscopic Anatomy | Structures studied with out a microscope |
| What is Surface Anatomy | The study of morphology and markings of the surface of the body |
| What is Regional anatomy | It is concerned with a specific area of the body. |
| What is Microscopic Anatomy | The structures studied with a microscope. |
| Name in order of increasing complexity the levels of structural organisation. | Chemical Level (Atoms & Molecules)Cellular Level (Made up of Molecules)Tissue Level (Consists of simular types of cells)Organ Level (different types of Tissues)Organ System LevelOrganismal Level (Whole Body) |
| Describe the Integumentary System | Skin - keeps the organs from drying out Forms the external cover |
| Describe the Skeletal System | Bones - Protects and Supports the Body Organs |
| Describe the Muscular System | Creates movement by using bones to creat locomotion, maintains posture and produces heat. |
| Describe the Nervous System | Fast acting control system, responds to internal and external changes by activating appropriate muscles and glands. |
| Describe the Endocrine System | Glands Screte hormones that regulate processes like growth and reproduction. |
| Describe the Cardiovascular System | Blood Vessels transport blood that carries oxygen nutrients and waste. |
| Describe the Lymphatic System | Houses white blood cells involved in immunity. |
| Describe the Respiratory System | Lungs - Keeps blood constantly supplied with oxygen and removes carbon dioxide. |
| Describe the Digestive System | Breaks down food into absorable units that enter the blood for distribution to body cells |
| Describe the Urinary System | Eliminates nitrogens wastes from the body, regulates water electroyte and acid base balance from the blood. |
| Describe the Reproductive System | Over function is production of offspring. |
| Name the body systems | Integumentary Skeletal Muscular Nervous Endocrine Cardiovascular Lymphatic Respiratory Digestive Urinary Reproductive |
| What is Homeostatis | the body's ability to maintain a relatively stable state internally when there is continuous change on the outside. |
| Name the General Control Mechanisms | Stimulus - pickes up changes in VariablesReceptors - detect changes sends response via afferent pathway to Control CentreControl center sets "set point" sends message via efferent pathway.Effector picks up respose and feeds back to stimulus. |
| Positive Feedback | Control infrequent events eg damage to lining of blood vessel |
| Negative Feedback | Regular controls where output decreases or shuts off original stimulus and works "opposite"the initial change. eg heating system |
| Homeostatic Imbalance | most disease is regarded as disturbance of Homeostatic |
| Maintenance of boundaries | body keeps the outside via Integumentary system protected from the internal organs etc |
| Movement | Skeletal system propels the body Movement via the internal organs |
| Metabolism | Sum total of all chemical reactions |
| Excretion | Process of removing wastes from the body. |
| Survival needs of the body | Nutients, Oxygen, Water body Temp and Atmospheric preasure |
