Term | Definition |
Major Function of Excretory System | Removes wastes (excess water, salts, ammonia, carbon dioxide and urea) from the body. |
Major Organs in the Excretory System | Kidneys, Urinary Bladder, Skin, Rectum, Anus, Lungs and Liver. |
Kidney, Urinary Bladder, and Skin | Clean, stores and removes liquid wastes |
Rectum/Anus | stores/removes waste |
Lungs | Removes carbon dioxide |
Liver | filters toxins from blood, produces bile. |
Excretion | process which removes waste from the body |
Perspiration | sweat...rids the body of salts/water; helps to regulate body temperature |
Excretory system works with other Systems | to clean blood of waste products that are produces by other systems. |
Major functions of Nervous System | Sends and receives information about the body's activities and monitors and responds to changes in the environment. |
Major Organs of Nervous System | Central and Peripheral Nervous System |
Central Nervous System consists of | Brain, Spinal Cord, and Nerve cells. |
Brain | part of central nervous system and controls most functions in the body. It consists of the cerebrum, cerebellum, and Medulla Oblongata. |
Cerebrum | Interprets input from the senses, controls the movement of skeletal muscles; carries out complex mental processes. |
Cerebellum | Coordinates the actions of the muscles; helps maintain balanace. |
Medulla Oblongata | controls involuntary actions |
Spinal Cord | links the brain and most of the nerves. |
Nerve Cells | allow for feeling |
Peripheral Nervous System | made of sensory organs. Sensory receptors detect changes in our environment. |
Neurons | nerve cell that is specialized to receive and conduct electrical impulses. |
Dendrite | short branched extensions of the cell that receive information |
Axon | elongated extensions of a neuron that carry impulses away from the cell body. |
Synapse | information from one neuron flows to another neuron across one of these. |
Nervous System and other systems | All of your tissues and organs receive instructions from the nervous system. |
Nerve impulse | nerve to spinal cord to brain |
reflexes | automatic response to certain stimuli |
