Cardiorespiratory System

The Cardiorespiratory system is responsible for the following functions within the human body:

  • Moving oxygenated blood from the lungs to the body, while at the same time moving de-oxygenated blood from the body back to the lungs via the heart.
  • Distributing the key nutrients to the cells around the body at the required rate. This takes place during exercise or rest.
  • Removing metabolic waste products such as Carbon Dioxide, Lactic Acid and Urea.
  • Regulation of blood PH balance to control acidosis or alkalosis.
  • Transporting hormones and enzymes to regulate physiological and psychological functions.
  • Maintaining fluid volume to prevent dehydration.
  • Maintaining body temperature by absorbing and redistributing heat through blood flow to the skin.
  • Cardiorespiratory Change from Exercise
    Regularly performing cardiorespiratory exercise will increase overall exercise capacity and contribute towards preventing cardiovascular disease. There area many short and long term benefits that come from regular cardiorespiratory exercise, these include :

  • Increased Cardiovascular Capacity
  • Decreased Myocardial Oxygen Demand
  • Increased Cardiac Output
  • Improved Left Ventricular Ejection (out to the body)
  • Lower Resting Heart Rate
  • Lowered Blood Pressure
  • Improved Metabolic Pathways
  • Improved Digestion
  • And Much More…..
  • Regular exercise will also help with a number of psychological improvements. People who are more physically active are likely to have better cognitive functionality, reduced cardiovascular response to stress, improved self-image, feeling of well-being, better personal relationship and lower rates of depression. Self confidence and self esteem will also improve.

    Cardiorespiratory System and Exercise
    The cardiorespiratory system is responsible for maintaining homeostatis in the body. One of the biggest challenges to homeostatsis is exercise through an increase in the demand for oxygen. A heavy exercise session can increase demand for oxygen by up to 15 to 25 times above the resting level.

    The primary function of the cardiorespiratory system us to deliver oxygen and remove metabolic waste products. The body adapts to meet these increased demands by :

    Increasing blood flow by increasing cardiac output.

  • Redistributing blood volume
  • Cardiorespiratory System
  • The main function of the cardiorespiratory system is to deliver Oxygen from the heart and lungs to our working muscles while removing Carbon Dioxide .
