Select all statements that are true of the respiratory system. View Available Hint(s) Kahlia was given antibiotics and told to rest. Bored by spending all day resting, Kahlia decided to learn more about her respiratory system. Select all statements that are true of the respiratory system. The alveoli have a simple squamous epithelium to allow for diffusion of oxygen and carbon dioxide across the respiratory membrane. All structures of the conducting and respiratory zone are lined by a serous membrane. Mucus-secreting cells are found throughout the structures of the conducting and respiratory zone. Both the alveolar wall and capillary wall contribute to the respiratory membrane. All structures of the respiratory system have cilia to move mucus.

The statements true are:

-The alveoli have a simple squamous epithelium to allow for diffusion of oxygen and carbon dioxide across the respiratory membrane

The alveoli represent the smallest functional units of the respiratory system and they are formed by simple squamous epithelium

-Both the alveolar wall and capillary wall contribute to the respiratory membrane

The respiratory membrane is composed by the walls of alveoli and capillaries and both structures are made up of simple squamous epithelium

UVA radiation causes lesions or DNA damage to melanocytes, which are the skin cells that produce the skin pigment known as melanin. Melanin is a protective pigment in skin, blocking UV radiation from damaging DNA and potentially causing skin cancer.
