The diaphragm is a piece of muscle situated at the undersurface of the lungs. 11.  The intercostal muscles are situated between the ribs.

  at that place are two types of intercostal        muscles, i.e. the internal intercostal muscle and the external intercostal muscle. The            intercostal muscles contract and re! lax to befriend the breathing process. 12.  Each alveoulus has a very thin ring which is moist and contains a large network of blood         capillaries. B.   breathing mechanism 1.   The human breathing mechanism involves two fleshly processes, i.e.  brainchild            (inspiration) and exhalation (expiration) which perish alternately without stopping. 2.   Air from the outback(a) is taken into the lungs through the inhalation process. 3.   In contrast, air is expelled from the lungs through the exhalation...If you want to get a full essay, order it on our website: BestEssayCheap.com
