Lung Diagram Functions

Match the following

• The opening of the nose that is lined with hair and mucus to trap particles.

• nares/nostrils

• Passageway in the back of the throat that is shared by air & food

• pharynx

• Connects nostrils to the pharynx, warms the air as it enters, and uses mucus to trap particles

• trachea

• Transports large quantities of air into the body

• oral cavity

• It has “C” shaped rings and is lined with mucus and cilia to trap particles.

• nasopharynx

Match the following

• Contains vocal cords where sound is produced

• vocal cords

• A flap that covers the trachea during swallowing to prevent food from entering the lungs

• epiglottis

• Opening to the trachea that is covered by the epiglottis during swallowing

• larynx

• Bands stretched across the larynx that vibrate to create sound

• glottis

Match the following

• Tubes made of cartilage & smooth muscles that enter the lungs

• bronchi

• Muscles between ribs.

• pleural membranes

• Surround the lungs & the lung cavity. It reduces friction during breathing.

• intercostal muscles

• Protects the heart & lungs

• rib

• Has 3 lobes and is used for breathing

• right lung

Match the following

• Small branches of the lungs that carry air to the alveoli

• bronchi

• Has 2 lobes & is used for breathing

• left lung

• Has 3 lobes and is used for breathing

• right lung

• Tubes made of cartilage & smooth muscles that enter the lungs

• bronchioles

• Flat muscle below the lungs that controls breathing

• diaphragm

Match the following

• Smallest blood vessels of the lungs that surround the alveoli for gas exchange

• pulmonary capillaries

• Small vein carrying oxygenated blood away from the alveoli and into the heart

• pulmonary venule

• Small artery containing deoxygenated blood and carries blood from the heart to the alveoli

• smooth muscle

• Cluster of alveoli at the end of a bronchiole where gas exchange occurs

• pulmonary arteriole

• Located in the respiratory tubes and provide structure and support

• alveolar sac

Match the following

• Small artery containing deoxygenated blood and carries blood from the heart to the alveoli

• pulmonary capillaries

• Smallest blood vessels of the lungs that surround the alveoli for gas exchange

• pulmonary venule

• Small vein carrying oxygenated blood away from the alveoli and into the heart

• pulmonary arteriole

• Small pouches of a single layer of epithelial cells that is surrounded by capillaries where gas exch

• alveoli

Match the following

• Coats the inner walls of the alveoli to reduce surface tension and make inflation & deflation easier

• carbon dioxide

• Blood that contains a large amount of oxygen but very little carbon dioxide

• oxygenated blood

• A gas that enters the lungs & capillaries. It is needed by cells for cellular respiration

• surfactant

• Blood that contains a large amount of carbon dioxide, but very little oxygen

• oxygen

• A gas (waste product of cellular respiration) that leaves the capillaries and is exhaled out

• deoxygenated blood
