Human Body Systems
| Question | Answer |
|---|---|
| blood vessels that carry blood away from the heart | arteries |
| blood vessels that carry blood toward the heart | veins |
| tiny air sacs that exchange carbon dioxide for oxygen | alveoli |
| the large artery that carries oxygen-rich blood away from the heart | aorta |
| the large artery that carries oxygen-poor blood away from the heart to the lungs | pulmonary artery |
| the large vein that bring oxygen-rich blood toward the heart from the lungs | pulmonary vein |
| these tiny blood vessels connect arteries to veins | capillaries |
| the network of blood vessels that carry blood from the heart to the body cells and from the body back to the heart | Systemic Circulation |
| network of arteries and veins that supply all the cells of the heart blood | Coronary Circulation |
| network of blood vessels that carry blood back and forth from the heart to the lung; exchanges oxygen-poor blood for oxygen-rich blood | Pulmonary Circulation |
| the waste product created during cellular respiration | carbon dioxide |
| tiny hairlike structures that line the respiratory system to keep foreign objects from entering the pathway | cilia |
| tubelike passageway at the top of the throat that receives air, food, and liquids from the mouth or nose | pharynx |
| flap of tissue that keeps food and liquids from entering the respiratory system | epiglottis |
| these folds of tissue vibrate to make sound as air passes over them-vocal cards | larynx |
| largest vein in your body that returns blood from the lower part of your body to your heart | inferior vena cava |
| microscopic air sacs found at the end of the bronchioles where the exchange of carbon dioxide and oxygen take place | alveoli |
| large muscle that contracts and relaxes and moves air in and out of the lungs | diaphragm |
| the trachea branches into two narrower tubes called | bronchi |
| Made from capillaries and larger blood vessels that join and form veins | venules |
| the mechanical and chemical breakdown of food that your body can absorb and use | digestion |
| physical breakdown of food into smaller pieces through mashing, chewing, and grinding food | mechanical digestion |
| chemical reactions break down foods into small molecules | chemical digestion |
| Proteins that speed up the rate of chemical reaction during digestion | enzymes |
| enzyme that breaks down proteins | pepsin and papain |
| enzyme that breaks down fats | lipase |
| waves of contraction that move food through the digestive system | peristalsis |
| the first part of the small intestines that digest carbohydrates, fats, nucleic acids, and proteins | duodenum |
| enzyme produced in the pancreas that breaks down carbohydrates and neutralize stomach acids | amylase |
| stores bile until it is needed | gall bladder |
| produces bile the break down fats | liver |
| substances that breaks down fats; made in the liver | bile |
| produces amylase that breaks down carbohydrates | pancreas |
| collected in the duodenum to be used by the body | carbohydrates, nucleic acids, fats, and proteins |
| oxygen-poor blood from the body enters heart | right atrium |
| oxygen-poor blood leave the right ventricle to go to the lungs | pulmonary artery |
| oxygen-rich blood enters the heart | pulmonary vein |
| oxygen-rich blood enters the heart through the pulmonary vein | left atrium |
| oxygen-rich blood leaves the left atrium to go | left ventricle |
| enzyme that breaks down fat | bile |
| stores excess bile and recycles it | gall bladder |
| secretes enzymes to aid in digestion | pancreas |
| breaks down proteins into amino acids | pepsin and papain |
| makes bile to aid in digestion | liver |
| absorption of nutrients inside the small intestine s wall through the bloodstream using these finger-like structures | villi |
| absorbs remaining nutrients and water | large intestine |
| enzyme that breaks down carbohydreates | amylase |
| amylase is made in this organ | pancreas |
| chemical enzymes that break down bonds in food. Begins chemical digestion in the mouth | saliva |
| substance found in stomach to chemically digest food | hydrochloric acid |
| semi-digested food that leaves the stomach and enters the first part of the small intestines (duodenum) | Chyme |
