Cardiovascular fitness is the ability of the heart, lungs and circulatory system to supply oxygen and nutrients to working muscles efficiently.
What is cardiovascular system?In order to maintain homeostasis in the cardiovascular system and provide adequate blood to the tissues, blood flow must be redirected continually to the tissues as they become more active. In a very real sense, the cardiovascular system engages in resource allocation, because there is not enough blood flow to distribute blood equally to all tissues simultaneously.
For example, when an individual is exercising, more blood will be directed to skeletal muscles, the heart, and the lungs. Following a meal, more blood is directed to the digestive system. Only the brain receives a more or less constant supply of blood whether you are active, resting, thinking, or engaged in any other activity.
Therefore, Cardiovascular fitness is the ability of the heart, lungs and circulatory system to supply oxygen and nutrients to working muscles efficiently.
