Respiratory System

• Respiratory System - to provide the body with a fresh supply of oxygen for cellular respiration and remove the waste product carbon dioxide
• Cell Type - Epithelial Tissue
• Nose

  • internal entry and exit point for air
• Pharynx

  • serves as a passage way for both air and food at the back of the throat
• Larynx

  • your “voicebox”, as air passes over your vocal chords, you speak
• Trachea

  • the “windpipe”, or what connects your pharynx to your lungs
  • a piece of skin, called the epiglottis, covers the trachea when you swallow, preventing food from entering
• Bronchi

  • the two large passageways that lead from the trachea to your lungs (one for each lung)
• The bronchi are further subdivided into bronchioles
• The further subdivisions lead to tiny air sacs called alveoli ; are in clusters, like grapes
• Capillaries surrounding each alveolus is where the exchange of gases with the blood occurs
• Lungs

  • contain the alveoli, bronchi and connective tissue
• The diaphragm is the muscle that causes you to breath

  hiccups are involuntary contractions of the diaphragm
