Review of the Organ System Excretory System Which system includes the following organs? • • • • kidneys skin lungs bladder Excretory System Name the organ system that: • removes wastes from the body such as urea and excess water Digestive System Which system includes the following organs? • • • • • • • • mouth esophagus stomach small intestine large intestine rectum liver gall bladder Digestive System Name the organ system that: • breaks down food into simpler molecules that can be used by the body chemical digestion • where food is broken down by chemicals in the body urea • a chemical produced when proteins are broken down in the body mechanical digestion • where food is physically broken down into smaller pieces by chewing Circulatory System Which system includes the following organs? • heart • blood • blood vessels Respiratory System Name the organ system that: • provides body with oxygen • removes carbon dioxide from body Respiratory System Which system includes the following organs? • trachea • bronchi • lungs Circulatory System Name the organ system that: • brings oxygen, nutrients, and hormones to cells • takes wastes away from cells • regulates body temperature Nervous System Which system includes the following organs? • Brain • Spinal cord • Nerves Nervous System Name the organ system that: • controls and coordinates the body • responds to stimuli inside and outside the body • controls the senses sensory neuron • a neuron that picks up stimuli from the environment and sends a nerve impulse toward the brain sensory neuron • The type of neurons stimulated when you hear a loud noise or touch something motor neurons • a neuron that carries an impulse to muscles telling them to contract or relax sensory neuron • a neuron that picks up stimuli from the environment and send a nerve impulse toward the brain interneurons • neurons found in the brain and spinal cord that carry impulses between sensory and motor neurons peripheral nervous system • the nerves that branch out from the central nervous system reflex • an automatic response that occurs without conscious control dendrite • the part of the neuron that carries impulses toward the cell body; receives impulses impulse • a message that a neuron carries relax • when a muscle returns to its original length motor neurons • the type of neurons used to jerk your arm in response to a noise contract • when a muscle gets shorter central nervous system • the brain and the spinal cord; the control center of the body axons • the part of the neuron that carries impulses away from the cell body; sends them to other neurons neurons • nerve cells; the basic unit of the nervous system The bicep relaxes. The tricep relaxes.
