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 |
