7 th Grade

The Respiratory System The system that exchanges oxygen and carbon dioxide You take 20 breaths per minute The lungs are very big organs but way relatively very little

The Respiratory System Two entrances— The nasal airway Nostrils or nares Nose hairs The nasal cavity Lined with mucous membranes Sinuses Secrete more mucous Make skull lighter The oral airway Mouth

The Respiratory System The Pharynx-known as the throat, around 5 inches long in an average adult Nasopharynx-superior part Oropharynx-middle part Laryngopharynx-inferior part The Larynx-known as the voice box Houses the vocal cords Adam’s Apple C-shaped strips of cartilage reinforce the structure

The Respiratory System Epiglottis-a flap of elastic cartilage, makes sure only air enters the larynx, forces food and liquids to travel down the esophagus Trachea-this is the windpipe, also has c-shaped cartilage for protection in the front.

The Respiratory System Right and Left Bronchi-the trachea breaks into two pathways, one to the right lung and one to the left lung. Bronchioles-The bronchi (think trunk of tree) fork into many different branches called bronchioles. Alveoli-The bronchioles continue to branch and eventually end at microscopic air sacs, gas is exchanged between the blood and these grape-like structures---there are at least 600 million alveoli in our lungs!!

The Respiratory System

Breathing Starts with a deep breath Mucous and Nose hairs filter the air Veins close to the skin in the nose warm the air The diaphragm-a narrow, dome-shaped muscle positioned immediately below the lungs contracts with a breath (flattens) The intercostal muscles-between each rib, the lower ribs push out just enough so air may fill up the lungs The lungs are literally “stuck” to the inside of the chest so they expand with the chest (two types of pleura) Gases move from high pressure to low pressure
