In the mass on a spring system: The period of oscillation DOES depend on the mass according to the equation: T = 2*pi*sqrt(m/k) T = period pi = 3.14 m = mass k = spring constant (i.e. how stiff the spring is) It DOES NOT depend on the length of the spring (which is why you don't see it in the above equation).
Pulmonary gas exchange takes place in the lungs between the alveoli and the blood. It is also referred to as âexternal respirationâ as it involves the respiratory processes that have contact with the external environment.
The air we breathe contains oxygen and other gases. Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide.Your bloodstream then carries this waste gas back to the lungs where it is removed from the blood stream and then exhaled. Your lungs and respiratory system automatically perform this vital process, called gas exchange.In addition to gas exchange, your respiratory system performs other roles important to breathing.our lungs and respiratory system automatically perform this vital process, called gas exchange.
