Class 11 biology ch 14 notes
Breathing - Exchange of gases
Respiration - Catabolic process
Physico chemical process and Breathing is a part of respiration.
Respiration are of 3 types.
a)Breathing
b)Exchange of gases at lungs level
c)Exchange of gases at tissue level.
Alveoli + blood - 1st physiological respiration
Blood + cell - 2nd cellular respiration
Aerobic respiration- presence of oxygen.
Anaerobic respiration- absence of oxygen.
E.g. Yeast,muscle cell.
Direct - Amoeba ,Sponges.
Indirect - all reptiles,amphibian.
Vestibule - Initial portion of vasal cavity.
