    respiratory system: lungs, diaphragm, trachea, bronchi, bronchioles, alveoli

    circulatory system (cardiovascular system): heart, arteries, veins, arterioles, venules, capillaries

    deoxygenated blood from heart to lungs through pulmonary artery, pumped by right ventricle

    oxygenated blood from lungs to heart into left atrium, through pulmonary vein, pressure from RV and LA

    as blood passes lungs, it passes through capillaries wrapped around alveoli which are highly vascular.

    oxygen from alveoli diffuse to blood

    carbon dioxide from blood to alveoli


    inspiration draws in oxygenated air for the body, expiration removes air with higher carbon dioxide concentration

    mechanisms for inspiration and expiration you can google it yourself

    I dont think you would gain much weight if any at all. If its only for a week. You could do an extra game or something else to make up the difference in calories burnt. If you are that bothered you could eat less calories. Eg if squash burns 300 less calories than running then eat 300 less calories that day. Personally I wouldnt worry about it. Changing your exercise routine is good as the body gets used to doing the same thing all the time.
