How are the cells in the respiratory system helping with kicking a ball? Do some have specific jobs?

Respiratory epithelial cells line the respiratory tract from trachea to bronchi into bronchioles and alveolar sacs. The primary functions of the respiratory epithelium, depending on their origin, is to moisten, protect the airway tract from potential pathogens, infections and tissue injury, and facilitate gas exchange.

Parents. Organisms have been known to live without their parents. For example, most reptiles, specifically snakes and a few others, live their entire lives from the moment they are born without their parents. However, energy and water are ESSENTIAL for life!

Hope that helps!
