Explain Cardiorespiratory System?
Write 1-2 paragraphs explaining the anatomy of the cardiorespiratory system and how blood flows through the heart and to the lungs and how oxygen is acquired and how carbon dioxide is released as waste.

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.
