respritory, excertor, cardivascular, lymphatic, and digestiver systems
| Question | Answer |
|---|---|
| system that takes in O2 and releases Co2 and H2O | Repritory system |
| air passageway from the pharnyx to the lungs | trachea |
| the upper part of the throat | larnyx |
| the 2 tubes that direct air into lungs | bronchus |
| sac like organs that exchannge gases with blood | alveoli |
| tiny sacs of lung tissue specialized for moving gasses between air and the blood in the body | bronchi |
| the muscle beneath the lungs that work with te rib cage to move air into lungs | diaphragm |
| this gas is needed for respiration | oxygen |
| these are surronded by cappillaries which exchange gasses after air enters these | alveoli |
| these two gases pass from the blood into the alveoli | ? |
| this system collects waste products by cells and removes waste from the body | excretory system |
| this system carries blood and other neede substances to the cells abd carries waste products away from the cells | cardiovascular system |
| hollow muscular organ that pumps blood through blood vessls only | heart |
| tube through which urine is excreted from the body | urethra |
| blood vessels that carry blood away from the heart | arteries |
| the 2 major organs of the excretory system that remove urea and other waste from the blood | kidneys |
| narrow tubes that carries urine from the kidney to the bladder | ureters |
| the 2 lower chambers of the heaRT | ventricle |
| this is a small tube through which urine is excreted from the body | urethra |
| this is the process air is taken out of lungs | respritory system |
| these help maintain homestasis by regulating the amoubt of water in ur body | urea |
| organ that is connected to the ureters on the top and urethra on the bottom | urinary bladder |
| this type of cell is made mostly of hemoglobin and carries oxygen through the blood | redblood cells |
| this type of cells helps fight off disease | white blood cells |
| this system is a network of vein-like vessls that returns lost fluids to the blood stream | lymphatic system |
| this is the liquid part of the blood | plasma |
| these filter lymph to fight disease causing bacteria | lyphnods |
| this protein attaches to oxygen in red blood cells | hemoglobin |
| this is the fluid in the lymphatic system | lymph |
| these help clot blood | platelets |
| this type of blood is oxygen rich | oxygeneated blood |
| this type of blood is oxygen poor | deoxygenated blod |
| these two chambers pump blood out of the heart | ventricle |
| these two chambers receive blood into the heart | atrium |
| blood vessels that carry blood to the heart | veins |
| blood vessels that carry blood away from the heart | arteries |
| what are the 3 main functions of digestion system? | Digestion, absorption, and elimination |
| What is digestion? | The process by which your body breaks down food into small nutrient molecules. |
| Where does mechanical digestion occur? | In your mouth. |
| What is chemical digestion? | Chemicals produced by the body break foods into theis smaller chemical building blocks. |
| Where does most chemical digestion occur? | In the mouth |
| What is absorption? | Process by which nutrient molecules pass through the wall of your digestive system into your blood. |
| What small structure in the small intestine absorbs nutrients into the bloodstream? | villi |
| What is the esophagus? | A muscular tube that connects the mouth to the stomach. |
| What substance lines in the esophagus to help you swallow and the stomach for protection? | mucus |
| What is saliva and what roll does in play in your digestion? | The fluid releases when your mouth waters. |
| What is the epiglottis? | Seals of your windpipe. |
| Wht is the structure and fuction of the liver? | Largest organ in the body. The role is to produce bile for the digestive system> |
| What is the structure and fuction of the gallbladder? | stores bile |
| What is the structure and function of the pancreas? | A triangular organ that lies between the stomach and the first part of the small intestine. Produces enzymes that flow into small intestine and help break down starches, protiens and fats. |
| What is the structure and the function of the small intestine? | Part of the digestive system where chemical digestion takes place. |
| What is the structure and function of the large intestine? | Last section of the digestive system that contains bacteria that feed on materials passing through. |
