Vital capacity: the maximum amount of air someone can expel from lungs after inhaling

Residual volume: the volume of air that’s remaining in the lungs after maximum exhalation

Minute volume: amount of gas exhaled or inhaled from a persons lungs within a minute

Normal tidal volume of gas moved in and out of the lungs per breath is 6 to 8 ml/kg

Volume of exhaled air after maximal inspiration is normally 60 to 70 ml/kg sometimes determined by size of thorax and lungs,

Oxygen diffuses from the bloodstream into the muscles and carbon dioxide diffuses into the blood from the muscles. 

Q2) When you inhale the intercostal muscles contract, expanding the ribcage, the diaphragm contracts, pulling downwards to increase the volume of the chest, pressure inside the chest is lowered and air is sucked into the lungs. 

When you exhale the intercostal muscles relax, the ribcage drops inwards and downwards, the diaphragm relaxes, moving back upwards, decreasing the volume of the chest, pressure inside the chest increasing the air is forced out. ]]> 2021-05-30 08:49:41 UTC https://padlet.com/ravindra_y_wsd/xqxdqikeqxcszsjy/wish/1571357024 https://padlet.com/ravindra_y_wsd/xqxdqikeqxcszsjy/wish/1571357144 Q1) during gas exchange oxygen moves from the lungs into the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This lets oxygen and carbon dioxide diffuse, or move freely, between the respiratory system and the bloodstream 
Q2) breathing occurs when the concentration or relaxation of muscles around the lungs changes the total volume of air within the air passages  (bronchi, bronchioles) inside the lungs.

Q2. breathing occurs when the contraction or relaxation of the muscles around the lungs changes the total volume of air within the air passages (bronchi, bronchioles) inside the lungs

Q3. Cardio-respiratory fitness (CRF) refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity while the cardio-respiratory system works together to get oxygen to the working muscles and removing carbon dioxide from the body, demanding for muscles to be supplied with more oxygen in order to contract and they produce more carbon dioxide as a waste product]]> 2021-05-30 08:51:41 UTC https://padlet.com/ravindra_y_wsd/xqxdqikeqxcszsjy/wish/1571359367 https://padlet.com/ravindra_y_wsd/xqxdqikeqxcszsjy/wish/1571360733 Oxygen goes into the alveoli a pocket like structure inside the lungs attached to the bronchi, which oxygen goes into the alveoli and then into the thin blood capillaries, while carbon dioxide goes out of the blood capillaries and out of the alveoli and lungs.

Jogging 3 km, as you run you’re muscles requires oxygen and glucose to contract and expand during the jog]]> 2021-05-30 08:53:02 UTC https://padlet.com/ravindra_y_wsd/xqxdqikeqxcszsjy/wish/1571360733 https://padlet.com/ravindra_y_wsd/xqxdqikeqxcszsjy/wish/1571365292 Oxygen from the alveoli goes into the blood vessel while the carbon dioxide from the capillaries goes into the alveoli which cause expiration in the lungs  the alveoli and capillaries are a one cell thick wall which means it is so thing air can go through it. ]]> 2021-05-30 08:58:02 UTC https://padlet.com/ravindra_y_wsd/xqxdqikeqxcszsjy/wish/1571365292
