Summary: Diving mammals use 5 techniques: 1. Change blood flow -send blood primary to the lung and heart -seal blood flow to the muscle goes to zero -tissues switch to anaerobic metabolism 2. Heart rate decreases -reduce oxygen demand in the heart 3. Blood composition changes (long term) -2x blood per unit mass -More blood goes to cells per unit volume 4. Exhale before dive -Help solve nitrogen problem (no bends) -No exchange takes place because air goes to the trachea and bronchi 5. ...

  -tissues switch to anaerobic metabolism
2. Heart rate decreases 
  -reduce oxygen demand in the heart
3. Blood composition changes (long term) 
  -2x blood per unit mass
  -More blood goes to cells per unit volume
4. Exhale before dive 
  -Help solve nitrogen problem (no bends)
  -No exchange takes place because air goes to the trachea and bronchi
5. Receptors sense presence of water 
  -Prevent breathing, no open mouth under water.
