The cardiovascular system

The cardiovascular system includes the heart and blood vessels (arteries, capillaries and veins) which transport blood to various regions of the body. Blood is pumped under pressure from the heart through the arteries. On returning to the heart, via the veins, the blood flows through one-way valves and is assisted by the action of skeletal muscles, which apply pressure externally.
Systematic exercise programs can produce changes in the functioning of the cardiovascular system. The heart size can increase, the resting heart rate can be lowered, and venous return can be improved by better muscle tone and blood volume and red cell count increased.
Most dance classes do not focus on cardiovascular conditioning. High levels of cardiovascular fitness delay the onset of fatigue and improve recovery rates from vigorous exercise, and it is therefore in the dancer’s interest to undertake training which focuses on this component.

The respiratory system
http://www.bartleby.com/107/240.html
The respiratory system includes the trachea (windpipe), the bronchi, the bronchioles, and alveoli (air sacs) of the lungs. The rib cage houses the lungs. The primary muscles of respiration are the intercostals, the serratus and the diaphragm. Breathing occurs as a result of the changes of pressure within the rib cage.
At rest, inhalation is active and exhalation is passive. During heavy exercise, the exhalation phase becomes the more active. Some dance techniques focus on breath-initiated movement, where the exhalation and inhalation accompany a contraction and release or fall and recovery.
