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.
Answer by Dylanleeprice. Confidence votes 74. In mammals diffusion occurs at 2 places in the respiratory system. The first place it occurs is in the lungs. The carbon dioxide from the blood diffuses into the lungs and the oxygen in the lungs diffuses into the blood.The second place where diffusion occurs is at the cell.Carbon dioxide diffuses out of the cell and into the blood whereas oxygen diffuses into the cell from the blood.he first place it occurs is in the lungs. The carbon dioxide from the blood diffuses into the lungs and the oxygen in the lungs diffuses into the blood.
