Oral Cavity

**** to get in oral cavity —> jokers cut: corner of mouth to ear; grab mandible and pull from maxilla

** cut through thorasic cavity w midline insistion and cont. to abdominal pelvic cavity then lift up flap so you dont hit viscera —> genital area and cut across and cut up the side and do other side

  • pallets - hard and soft

    • stop nasal and oral cavitys from merging and creates a food bolus

  • pharynx - back of throat

  • 5 senses of taste: salty, sweet, sour, bitter, umami

  • esophogus: food

  • trachea: air; ridged; location = front

    • epiglotis - covers trachea while swallowing

  • dentition - collection of teeth

  • salavary glands - make saliva

    • mastication to make a food bolus

  • diaphram - seperates thoracic cavity from abdominal-pelvic cavity

Respiratory System

  • Purpose - oxygen and carbon dioxide exchange for respiration

  1. nose (more protection and filteration)

  2. down the trachea

  3. bronchi

  4. bronchioles

  5. aveoli

  • in aveoli theres gas exchange; diffusion (high to low concentration)

  • breathing done by movement of muscles (diaphram)

  1. diaphram goes up

  2. lung pressure is up

  3. volume decreases (boils law)

  • asthma

  • Pulmonologist

Heart

***Cut oracle to oracle

  • nestled in lungs for protection

  • membrane - pera cardium

Blood through heart! (1 min heart)

  • Blood comes into the right atrium from the body

  • moves into the right ventricle and is pushed into the pulmonary arteries in the lungs.

  • the blood travels back to the heart through the pulmonary veins into the left atrium,

  • to the left ventricle and out to the body's tissues through the aorta.
