Respiratory System

Summary: The word respiration means breathing. In the respiratory system, the lungs are the main organs. It is a group that supplies the body with oxygen. The organs work together to convert air that is breathed in to oxygen for your blood. In order for the cells to function, the cells need oxygen. The respiratory system is the system for taking in oxygen and giving off carbon dioxide, but only land animals accomplish this by breathing. The respiratory system is made up of organs that help you breathe. The reason the respiratory system is important is because we could not live without air, breathing is something you need in your body. The way it works is when you inhale oxygen, it goes through the trachea, then follows through the baronial and ends at the alveoli.

Organs-

Trachea	Moves air in and out of lungs Bronchus	Sends equal amounts of air to each lung Lungs	Carry out work and supplies the body with oxygen and remove carbon dioxide Larynx 	Keeps airways open and produces sound Diaphragm	Controls amounts of air into lungs Pharynx	Allows passage of air to the lungs Epiglottis	Prevents food from entering the trachea when swallowing Vocabulary	Definition Respiration	The process in which oxygen and glucose undergo a complex series of chemical reactions inside cells; also known as cellular respiration. Cilia	Tiny hair-like extensions that move together in a sweeping motion. Pharynx	The throat; part of both the respiratory and digestive systems. Trachea	The windpipe; a passage through which air moves in the respiratory system. Bronchi	The passages that direct air into the lungs. Lung	An organ found in air-breathing vertebrates that exchanges oxygen and carbon dioxide with the blood. Alveoli	Tiny sacs of lung tissue specialized for the movement of gases between air in blood Diaphragm	A large muscle located at the bottom of a mammal’s ribs cage those functions in breathing. Larynx	The voice box; located in the top part of the trachea, underneath the epiglottis. Vocal Cords	Folds of connective tissue that stretch across the opening of the larynx and produce a person’s voice. Carbon Monoxide	A colorless, odorless gas produced when substances including tobacco are burned. Bronchitis	An irritation of the breathing passages in which the small passages become narrower than normal and may be clogged with mucus

Fun Facts: •	An average person can breathe about 13 pints every minute •	Everyday, you breathe 20,000 times.

Interesting Facts •	300 million alveoli may be found in a pair of human lungs. •	Fastest human speed is 120 miles per hour. •	In humans, the right lung slightly is bigger than the left •	The breathing rate is faster in children and women than in men.
