When are a fetus lungs fully developed?

The development of lungs comprises of 5 distinct stages: The first and last stages, i.e. Embryonic and Alveolar stages are almost 5 weeks in duration (but alveolar stage continues after birth to childhood) and the middle 3 stages, i.e. Pseudoglandular, Canalicular and Terminal saccular stages are almost about 10 weeks in duration.

What is end stage small cell lung cancer? Physical changes during the final stages of lung cancer can be related to the tumor in the lungs, the spread of cancer to other parts of the body, or due to the terminal stages of cancer in general. By definition, the final stage of lung cancer implies that treatment options have been exhausted; a cure is not possible.

How do the lungs develop? In embryonic development, the lungs begin to develop as an outpouching of the foregut, a tube which goes on to form the upper part of the digestive system. When the lungs are formed the fetus is held in the fluid-filled amniotic sac and so they do not function to breathe.
