Respiratory System

oxygen

• the act of expelling air from the lungs
• lowers blood pH. Our medulla sends a signal to breathe in response to a rise in this gas
• the act of exhaling air suddenly with a noise
• most _________ in the blood is carried bound to hemoglobin

nasal cavity

• specialized protein that carries oxygen on red blood cells
• the cavity behind the nose and above the roof of the mouth that filters air and moves mucous and inhaled contaminants outward and away form the lungs.
• the act of expelling air from the lungs
• a symptom consisting of the involuntary expulsion of air from the nose

bronchioles

• Two short branches located at the lower end of the trachea that carry air into the lungs.
• small tubes that branch off the bronchi that contain clusters of alveoli at each end.
• voice box; passageway for air moving from pharynx to trachea; contains vocal cords
• a flap of cartilage that covers the windpipe while swallowing

trachea

• the act of expelling air from the lungs
• The main air tube leading into the respiratory system. The trachea is made of alternating rings of cartilage and connective tissue.
• Lungs, bronchi, trachea, pharynx, larynx, epiglottis, nose
• the act of inhaling

larynx

• a symptom consisting of the involuntary expulsion of air from the nose
• the act of inhaling
• voice box; passageway for air moving from pharynx to trachea; contains vocal cords
• muscle that forms the thoracic floor, when it contracts it flattens and help lungs expand for inhalation

respiratory system

• system responsible for taking in oxygen and releasing carbon dioxide using the lungs
• lowers blood pH. Our medulla sends a signal to breathe in response to a rise in this gas
• a symptom consisting of the involuntary expulsion of air from the nose
• most _________ in the blood is carried bound to hemoglobin

hemoglobin

• most _________ in the blood is carried bound to hemoglobin
• The main air tube leading into the respiratory system. The trachea is made of alternating rings of cartilage and connective tissue.
• specialized protein that carries oxygen on red blood cells
• The process of breathing. One inhale and one exhale

Carbon dioxide

• lowers blood pH. Our medulla sends a signal to breathe in response to a rise in this gas
• voice box; passageway for air moving from pharynx to trachea; contains vocal cords
• Two short branches located at the lower end of the trachea that carry air into the lungs.
• the cavity behind the nose and above the roof of the mouth that filters air and moves mucous and inhaled contaminants outward and away form the lungs.

capillaries

• voice box; passageway for air moving from pharynx to trachea; contains vocal cords
• tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and the cells of the body
• most _________ in the blood is carried bound to hemoglobin
• The main air tube leading into the respiratory system. The trachea is made of alternating rings of cartilage and connective tissue.

organs of the respiratory system

• a symptom consisting of the involuntary expulsion of air from the nose
• muscle that forms the thoracic floor, when it contracts it flattens and help lungs expand for inhalation
• the cavity behind the nose and above the roof of the mouth that filters air and moves mucous and inhaled contaminants outward and away form the lungs.
• Lungs, bronchi, trachea, pharynx, larynx, epiglottis, nose
