Human Body-Science
The skeletal, respiratory, and nervous system
| Term | Definition |
|---|---|
| function of respiratory system | to bring oxygen into the body, and to remove carbon dioxide and water |
| gas exchange in alveoli | oxygen diffuses out of alveoli into the blood, carbon dioxide diffuses out of blood and into alveoli to be released by the lungs |
| how does breathing work? | the diaphragm pushes down and relaxes, allowing for more or less room, letting you breathe |
| breathing vs respiration | breathing is the process inhaling and exhaling gases between the cells and environment, respiration is a chemical process that takes place inside the cell that exchanges carbon dioxide and oxegen |
| function of temporal lobe | managing your emotions, processing information from your senses, storing and retrieving memories, and understanding language. |
| function of frontal lobe | voluntary movement, expressive language and higher level thinking, (last to develop) |
| function of parietal lobe | sense of touch and assembles input from your other senses into a form you can use |
| function of occipital lobe | visual perception, color, form and motion |
| how does the nervous system work | neurons transmit signals throughout your body, carrying info from your brain, allowing for a reaction to your environment, moving, feeling, thinking, etc |
| CNS vs PNS | The Central Nervous System contains your brain and spinal cord and communicates with the body. the Parietal Nervous System is nerves and neurons communicating with the rest of the body. |
| how neurons send signals from brain to action | neurons send neurotransmitters across a tiny space in order to send signals from the brain allowing for actions. |
| Long bone | long bone-femur/humerus, supportive |
| function of the skeletal system | provides support for the body, protects internal organs from damage, produces red and white blood cells |
| Ball and socket joint | ball+socket joint-shoulder+hip-wide range of motion |
| levels of organization in body | cell, tissue, organ, organ system, organism |
| cell body | basic building block of all living things |
| tissue | a group of connective cells that have a similar function |
| organ | structure that contains two or more different tissues that work together to do the same job (epithelial, muscle, nervous and connective tissues |
| organ system | a group of organs that work together to carry out a complex function (digestive system, nervous system etc). |
| organism | any living thing that functions as an individual |
| Short bone | short bone-small movements, ankle/wrist |
| irregular bone | irregular bone-fill extra space, vertebrae/pelvis/mandable |
| flat bone | flat bone-protects helps w movements scapula/ribs/sternum |
| hinge joint | hinge joint-elbow+knee-low range of motion |
| gliding joint-bones slide over each other-wrist and ankle | gliding joint-bones slide over each other-wrist and ankle |
