Ventilation is the process by which air moves in and out of the lungs.Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the gas in the alveoli and the blood in the capillaries in the lungs.
Explanation:
Función. Los ribosomas son responsables de la síntesis de proteínas, en un proceso conocido como traducción. La información necesaria para esa síntesis se encuentra en el ARN mensajero (ARNm), cuya secuencia de nucleótidos, determina la secuencia de aminoácidos de la proteína.
Steam radiators and hot water radiators are very similar, so much so that in many cases they are interchangeable. Many homes have been converted from steam to hot water heating systems (and vice versa) without having to change the actual radiators.
The most obvious difference between the two is that a hot water radiator is always equipped with two connections: hot water goes into the radiator on one side, and the cooled water leaves on the other. Steam radiators can have either one or two connectors: hot steam can enter on one side, and condensed water can leave either through the same pipe or through a pipe on the other side.
While it is certainly best to use a steam radiator for steam and a hot water radiator for water, in some cases a switch between the two will require only a few simple operations.

"The relationship between the amount of energy reaching an object (or portion of it) and the amount leaving it.
A good example of this is our earth receiving energy from the sun, and giving off energy into the near future." (From Wiktionary)
