type II alveolar cells
Your respiratory system becomes mature in last few weeks of the gestation. Premature babies get problem in respiration. They do not have surfactant in there respiratory system. You have yo give corticosteroid shots to mother, if you plan to deliver her prematurely.
Surfactant helps reduce surface tension within the alveoli, thus preventing each alveolus from callapsing as air moves in and out during respiration.
There is really no known body system that is referred to as the excretory system, but instead many other body systems contribute to the process: Respiratory, Alimentary, Integumentary, and Urinary systems are among the major ones. ..
The respiratory system
The respiratory system brings in air containing oxygen, and the oxygen is absorbed by the circulatory system. Capillaries surrounding the alveoli absorb inhaled oxygen into the blood.
The respiratory system is the system that handles breathing.
Circulatory system delivers blood (containing oxygen) to cells.
