Respiratory System. Chris Donovan Joe Skworch Gary Resner. Bronchitis. Bronchitis is an inflammation of the lining of the bronchial tubes. The bronchi become infected and less air is able to flow to and from the lungs, and a heavy mucus is coughed up.
The nasal passage warms and adds moisture to the air you breathe.
The epiglottis is a flap that closes over the trachea during swallowing preventing choking.
The bronchi is a short tube that carries air from the trachea to each lung
The diaphragm is the muscles at the bottom of the chest cavity that enables breathing
The trachea is a tube that carries air from the nasal chamber to bronchi
The lung is the main organ of this system. Gas exchange occurs here.
The alveolus is and air sac where gas exchange occurs between your blood and the air you breath
Capillaries are blood vessels that surround the alveoli
Exhaling = When the diaphragm relaxes, the cavity inside your body gets smaller and your muscles squeeze your ribcage and your lungs begin to collapse as the air is pushed up and out of your body in an exhale, which reduces the air pressure in your lungs.
Inhaling = Inhaling begins when the diaphragm pulls down, and lowers the internal air pressure. When the air pressure is greater outside, you suck in the air in an inhale, which expands your lungs and increases the air pressure in your lungs.Inhaling & Exhaling
