| Question | Answer |
|---|---|
| describe smooth muscle | involuntary muscle that are found in the intestines and in the bladder |
| type of muscles that you control | Skeletal/voluntary |
| involuntary muscles that are in your heart | cardiac |
| muscles that are used to move bones | Skeletal/voluntary |
| Describe villi | fingerlike projections that increase the surface area in the small intestine |
| body part that is involved in the ingestion of food | mouth |
| describe the stomach | a muscular bag that is used to break down food with enzymes |
| Describe the large intestine | a long tube that is used to absorb water from food |
| What are accessory organs | organs that are used to produce or store enzymes and chemicals that help break down food |
| Job of tendon | connect muscle to bone |
| Job of ligament | hold bones together |
| Job of bone marrow | Produce blood cells |
| flexible tissue that cushions the end of bones and acts as a shock absorber | cartilage |
| the blood vessels that carry blood to your heart | veins |
| cells that are used to fight off infection | White blood cells |
| liquid part of blood that carries blood cells and nutrients to cells and waste away from cells | plasma |
| blood vessels that carry blood away from the heart | arteries |
| blood vessels that allow materials to enter and leave the blood | Capillaries |
| blood cells that carry oxygen | Red blood cells |
| a muscle beneath your lungs that helps move gases in and out of your lungs | diaphragm |
| difference between bronchi and pharynx | Both carry gases in and out of the body, but pharynx also carries food and water to the digestive system |
| grapelike clusters that form the lungs and allow gases to enter/leave blood | alveoli |
| increases surface area for gases to diffuse into and out of blood | alveoli |
| chemical process—respiration or breathing? | respiration |
| burning food with oxygen to release energy | respiration |
| bring air into the lungs--respiration or breathing? | breathing (inhale) |
| Type of digestion: churning of food | Mechanical digestion |
| Type of digestion: adding of saliva in mouth | Chemical digestion |
| Type of digestion: chewing food | mechanical digestion |
| type of muscle used: heart pumping blood | Involuntary / cardiac |
| type of muscle used: walking | Voluntary/skeletal |
| type of muscle used: digestive system moving food | Involuntary/smooth |
| type of muscle used: holding a pencil | Voluntary/skeletal |
| Describe inhalation | ribs are out and up, chest cavity is large |
| Describe exhalation | chest cavity is small, diaphragm up/relaxed |
| Job of the digestive system | break food into small molecules so it can diffuse into the blood |
| Jobs of circulatory system | deliver food and oxygen to the cells of the body, carry carbon dioxide away from the cells of the body, fight infections, heal wounds, |
| Jobs of respiratory system | bring oxygen into the body and release carbon dioxide out of the body |
| Jobs of skeletal system | Make red blood cells, store minerals, provide structure and support, protect organs |
| Jobs of muscular system | Move bones, move internal organs, push materials through internal organs |
| Describe the 4 jobs of the digestive system in order | 1. ingestion brings food into the mouth 2. mechanical digestion breaks food into small pieces 3. enzymes chemically digest food into small enough molecules that can be 4. absorbed into the body cells by diffusion |
| Describe the pulmonary "loop" of the circulatory system | blood travels from the heart to the lungs, drops off CO2 and picks up O2, goes back to heart |
| describe the systemic "loop" of the circulatory system | blood travels from the heart to all of the systems of the body to deliver and pick up wastes, food, etc. and then comes back to the heart |
| What organs carry out mechanical digestion? | mouth & stomach mainly |
| What organs carry out chemical digestion? | mouth, stomach and small intestine |
| Job of platelets | help blood to clot |
| Describe how your body prevents choking | when you swallow, the epiglottis covers the trachea to prevent food or water from entering |
