Autonomic Nervous system
- system of nerves that control involuntary functions

- specialized, impulse-conducting cells (composed of cell body, axon, dendrites)
- cord of nerve tissue extending through the spinal column
- something that causes an action (example-stimulus: hot stove, response: moving hand away from hot stove)
- exercise that increases the need for oxygen
anaerobic exercise examples
- exercise that builds muscles through tension
- two upper chambers on each side of the heart, receives blood from veins and forces blood into ventricles
- circulates in body to sustain life
- any of the vessels (arteries, veins, capillaries) through which the blood circulates
- relating to the heart
- organ (consisting of four chambers) that circulates blood, divided into four chambers (valves)
- flowing (such as the flow of blood throughout the body)
- contains blood's proteins, suspends blood cells
- transports blood from the heart to the lungs
red blood cells
- carries oxygen to your body
- regular throbbing of arteries caused by heart contractions
- located in the heart, left and right, pumps blood to the entire body
White blood cells
- fight off infections and diseases
- smallest blood cells to help form clots if you have an injury
- sheet-like muscle separating the chest from the abdominal cavity; creates suction to draw in air and expand lungs.
to breathe out
to breathe in
Larynx (voice box)
Voice box, Triangular shaped chamber below pharynx that contain vocal cords and Adam's Apple. Is covered by the Epiglottis when swallowing.
- two respiratory organs.
nasal passages (nasal cavity)
- helps with inhaling and exhaling of air through the nose.
- throat; collects incoming air from the nose and passes air to the trachea.
- inhaling and exhaling air, breathing.
- hollow spaces in the bones of the head, helps regulate temperature of air breathed in.
- A bitter, alkaline, yellow or greenish liquid, secreted by the liver, which aids in absorption and digestion, of fats.
- where solid waste exits through the body
- located near the small and large intestine, purpose unknown
- stores bile (yellow, green liquid from the liver)
- Involuntary muscular actions that moves food along during digestion.
- A disorder of carbohydrate metabolism characterized by inadequate production or use of insulin, resulting in high glucose levels in the blood and urine, excessive urination and persistent thirst, as well as other complications such as infection and blindness.
- organ in the mouth; functions include eating, tasting, speaking
- Digestive secretions of the stomach glands consisting chiefly of hydrochloric acid, mucin and enzymes.
- organ in the digestive system that stores and digests foods.
- The long, narrow, coiled section of the intestine that extends from the stomach to the beginning of the large intestine. Nutrients from food are absorbed into the bloodstream from the small intestine.
- secretes (releases) saliva
- watery fluid for tasting and swallowing food, chewing, keeping mouth moist
- straight section of the intestine, ending in the anus, stores solid waste
- about 6" long, located behind the stomach, secretes insulin
where digestion begins
- filters blood coming from the digestive tract, releases bile, helps take toxins (poisons) from chemicals in the body
- where stool (solid waste) accumulates
- The process by which food is converted into substances that can be absorbed and assimilated by the body.
- muscular passage connecting the mouth and the stomach, rhythmic motion

A living thing
: everything that surrounds an organism and influences it
any organism that makes it own food through photosynthesis
: living things in an ecosystem such as plants and animals
: an organism that gets it energy by eating other organisms
: an organism that gets its energy from breaking down decaying organic material into nutrients for an ecosystem; nature's recycler
