Respiratory System

• Respiration


  in order to metabolize, organisms use basic mechanisms like diffusion to inhale oxygen and expel carbon dioxide
• 2 types of respiratory system in animals

  1. Aerobic
  2. Anaerobic
• Aerobic Respiration


  uses oxygen to produce energy from food
• Gas Exhange of Animals


  1. Skin System
  2. Gills System
  3. Tracheal System
  4. Lung System
• Skin System


  animals such as amphibians who dwell in damp environment breathe in oxygen through their moist body surface
• Gills System


  used by animals such as fishes take in dissolved oxygen from water
• Tracheal System


  the trachea used by animals such as insects to enable gas exchange
• Lung System


  inside the cavities of terrestial animals, lungs are a pair of organs separated into small chambers packed with capillaries
• Functions of Respiratory System


  1. Facilitate the exchange of gases between between air and blood.
  2. Supply oxygen to blood and the entire body.
  3. Remove and dispose Co2 away from the body.
• Parts of the Respiratory System


  1. Mouth and Nose
  2. Pharynx
  3. Larynx
  4. Trachea
  5. Bronchi
  6. Lungs
  7. Alveoli
• Mouth and Nose


  the opening where air enters into the respiratory system.
• Pharynx


  the tube that brings air into the trachea
• Larynx


  the part of the respiratory system that produces sounds
• Trachea


  it connects larynx and bronchi. it contains epiglottis that covers the larynx
• Bronchi


  it connects and brings air inside the lungs
• Lungs


  it contains alveoli where exchange of carbon dioxide and oxygen takes place
• Alveoli


  where exchange of gases takes place (oxygen is distributed in the body while carbon dioxide is released outside the body)
• Respiratory System of Plants


  1. Cellular Respiration
  2. Roots
  3. Stem
  4. Stomata
  5. Guard Cell
• Cellular Respiration 


  the process through which organisms convert glucose into a form that may be used by cells for energy.
• Roots 


  it carries oxygen from the air, water and nutrients
• Stem


  used as passageway for the air, water, and nutrients to pass through
• Stomata


  It is the opening into the leaf that allows oxygen and carbon dioxide to diffuse
• Guard Cell 


  it regulates the transpiration happening in the stomata
• Photosynthesis


  1. The root absorbs water and minerals from the soil
  2. Water and minerals travel inside the plants.
  3. Chloroplasts trap sunlight.
  4. Oxygen is released outside the guard cell and stomata.
  5. Carbon Dioxide enters the guard cell and stomata.
  6. Sugar were released outside the plant.
• Cellular Respiration


  1. The roots absorb water and nutrients from the soil.
  2. Water and minerals travel inside the plants.
  3. Oxygen goes inside the guard cell and stomata.
  4. Carbon Dioxide goes outside the guard cell and stomata.
  5. Sugar travels inside the plant.
