respiratory system

• Respiration


  the process of gas exchange—the release of carbon dioxide and the uptake of oxygen that occurs between RBCs and alveoli
• external respiration


  inhaling and exhaling
• internal respiration


  Exchange of gases between cells of the body and the blood
• oxygen and carbon dioxide


  needs for gas exchange to occur
• Alveoli


  the only part in the respiratory for gas exchange
• nasopharynx, oropharynx, laryngopharynx


  3 parts of the pharynx
• because of the hormone of testosterone


  why is the voice box of male protuding
• because the vocal cords are attached


  why is larynx called "voice box"
• uvula


  -soft tissue hanging from the middle of the soft palate

  -prevents food and liquid from going up your nose
• nasal cavity


  hollow space behind the nose
• nasal septum


  partition separating the right and left nasal cavities
• Cilia


  -hair in the nose that trap particles before getting into the lungs
• olfactory receptors


  nerve endings that act as the receptors for the sense of smell
• Conchae


  create turbulence in the air to trap particulate matter in mucus
• sinus


  Cavity within a bone, filled with air and lined with mucous membrane
• frontal bone, sphenoid bone, ethmoid bone, maxillary bone

  4 sinuses
• ethmoid sinus


  sinus located near the eye
• frontal sinus


  sinus located between eyebrows
• sphenoid sinus


  sinus located near the ears
• maxillary sinus


  sinus located near cheekbone
• rheumatic heart disease


  sickness that happens if you dont help tonsilitis to heal
• tonsillectomy


  surgical removal of the tonsils
• Heimlich maneuver


  procedure that removes food or other obstacles from a choking person's airway
• Trachea


  windpipe
• nasopharynx


  superior region behind nasal cavity
• oropharynx


  middle region behind mouth
• ciliated mucus


  -hair in the trachea

  -move the particles trapped in the mucus out of the nose

  -moves up if we inhale
• holus


  where lung is attached
• Emphysema


  too much water vapor in lungs leading to ruptured alveoli
• pleura or peritoneum


  double-layered membrane surrounding each lung that protect and cushion the lungd
• Diffusion


  Movement of molecules from an area of higher concentration to an area of lower concentration.
• right atrium


  Receives deoxygenated blood from the body
• right ventricle


  pumps deoxygenated blood to the lungs
• left atrium


  receives oxygenated blood from the lungs
• left ventricle


  pumps oxygenated blood to the body
• 2


  number of lobes in the lung left side?
• 3


  number of lobes in the right left side?
• Diaphgram


  muscle at the base of the abdominal cavity; contracting = inhalation
• Inhalation


  -lungs raise, diaphragm contracts

  -great pressure outside and low pressure inside
• Exhalation


  -lungs contracts, diaphragm raises

  -great pressure inside and low pressure outside
