Choose one of the biological systems and explain the health implications of an enlarging child 32 m tall

Choose one of the biological systems and explain the health implications of an enlarging child 32 m tall?
Transpiration system: Your body generates heat according to its volume. But the rate of cooling depends on the area of your skin, since an important cooling mechanism is perspiration. As the water in your skin evaporates it helps keep you cool. Respiratory system: All the cells in your body require oxygen. The number of cells depends on volume, but the amount of oxygen processed by your respiratory system depends on the surface area of your lungs. Skeletal system: Your mass depends on volume, but he strength of your bones depends on area of their cross-section. what health problems are implied for one or more of the categories?

Transpiration system: We lose heat in proportion to our Surface Area to Volume Ratio meaning the bigger the volume the less heat is lost. This means a really big person wouldn't be able to be active without going hyperthermic. Respiration System: A big person would have bigger lungs to compensate and so the size of the person wouldn't affect the amount of oxygen the body can get. Skeletal System: If you're talking about a guy who's just really tall and not really fat then your bones wouldn't grow outwards meaning they'd be relatively thin and prone to snapping.
