Respiratory System

consists of specific organs responsible for supplying the blood with oxygen and expelling carbon dioxide

serves as the main entry / exit for air where it is warmed, filtered and humidified to get rid of foreign substances; it has two openings, the nostrils (or nares)

a muscular tube found behind the mouth and nasal cavity which serves as the passageway for air and food

it is formed by several cartilages whose function is to connect the pharynx and trachea and for the production of sound and speech

a flap of tissue that acts as a protective barrier for the lungs

made up of rings of cartilage making it flexible enough to keep the passageway open for air; Its cilia push mucus and dust particles and bacteria toward the throat

tinier branches of the main bronchi going to the air sacs

thin-walled bulbs referred to as the sites of respiration

main organs of the respiratory system which are large, elastic, spongy sacs

a dome-shaped muscle separating the chest from the abdomen that aids in respiration

tissue that acts as a protective barrier for the lungs.

two tubes that conducts air into the lungs: the left bronchus which is narrower, longer and less straight than the right bronchus.

thin membrane covering the lungs

process of using oxygen to break down sugar in food producing energy in cells and releasing carbon dioxide as a waste product.

exchange of oxygen and carbon dioxide between the air and the blood within the lungs.

formed by several cartilages whose function is to connect the pharynx and trachea and for the production of sound and speech.

dome-shaped muscle separating the chest from the abdomen that aids in respiration

specific organs responsible for supplying the blood with oxygen and expelling carbon dioxide.

inhaling or taking in oxygen, and exhaling or releasing carbon dioxide out of the lungs

breathing center of the brain that regulates the breathing rate

exchange of oxygen and carbon dioxide between the blood and the body cells.
