| Question | Answer |
|---|---|
| cell | the building blocks of all plants and animals |
| single-cell organism | a microscopic organism made of one cell that is able to carry out all life processes |
| muli-cell organism | an organism that consist of more than one cell and use transport systems to carry out life processes |
| bacteria | unicellular organism (microscopic) |
| body systems | important systems that work together to maintain health and fitness |
| cardiovascular system | consist of the heart, blood vessels, and blood; transports nutrients and oxygen and removes gaseous waste from the body (also know as the circulatory system) |
| circulatory system | consist of the heart, blood vessels, and blood; transports nutrients and oxygen and removes gaseous waste from the body (also know as the cardiovascular system) |
| heart | muscular organ about the size of a fist that pumps blood to the body and lungs |
| right side of heart | recieves oxygen poor blood from the body and sends it to the lungs to receive oxygen |
| left side of heart | receives oxygen rich blood from the lungs and sends it to the body |
| blood vessels | carry blood from place to place |
| arteries | carry blood away from the heart |
| veins | carry blood to the heart |
| capillaries | narrow vessels that carry blood from arteries to veins |
| nervous system | body's control center that is made up of the brain and spinal cord |
| brain | control center made up of the cerebrum and brain stem |
| brain stem | lowest part of the brain that controls heartbeat, breathing, blood pressure, and muscles in the digestive system |
| muscular system | works with the skeletal system to allow movement |
| skeletal muscle | muscles that are attached to bones |
| cardiac muscle | muscles found in the heart |
| smooth muscle | muscles that make-up internal organs and blood vessels |
| tendon | tough cords that attach muscles to bones |
| skeletal system | the body's supporting frame made of bones; gives body shape, protects organs, works with muscles to allow movement |
| 206 | number of bones in the skeleton |
| joints | a place where 2 or more bones meet |
| immovable joints | bones fit together too tightly to move |
| partly movable joints | bones can moce only a little |
| movable joints | places where bones can move easily |
| bone marrow | tissue found inside bones responsible for making red and white blood cells |
| digestive system | breaks down food into simple substances that the body can use |
| mouth | the place where digestion begins |
| esophagus | muscular tube that transports food from the mouth to the stomach |
| stomach | stores food and produces gastric juices that break down into nutrients |
| liver | produces bile to help break down food and absorb fats |
| pancreas | produces insulin, which is used to move sugar from the blood into the body cells |
| small intestine | has finger like villi that absorb nutrients into your blood |
| large intestine | absorbs water and vitamins from the undigested food; stores the solid until it is eliminated |
| respiratory system | gets and uses oxygen in the body , removes carbon dioxide (waste) from the body |
| trachea | the tube that air travels down to the lungs |
| bronchial tubes | trachea splits in to these two tubes, one going to each lung |
| bronchioles | smaller tubes branching from the bronchial tubes |
| aveoli | tiny air sacs that exchage carbon dioxide for oxygen |
| lungs | one of the largest organs in your body; sponge like organs that expand and contract when you inhale and exhale; protected by the ribs |
| diaphragm | a dome-shaped muscle that works with your lungs to allow you to inhale and exhale |
