Question

Which of the following identifies the structural hierarchy that makes up the pulmonary system in order of increasing complexity?

Answer 1

Answer:

B

Explanation:

Cells that have differentiated to perform a specific function make up a tissue, tissues of a specific function make up an organ, and organs that coordinate to perform one or more functions make up an organ system. Another organ system is the digestive system made up of organs such as the esophagus, ileum, and stomach. The organs are made up of many tissues types like the muscle tissue that is made of smooth muscle cells.

Answer 2

Answer:

B, lung cell, lung tissue, lung, pulmonary system

Explanation:

Lung cells are also called as pleural cells. Lung cells to form lung tissue which then forms the lung and lung and its function forms the pulmonary system. The complexity increases from cell to organ system.

Pulmonary system plays a major role in respiration. Lung cells once damaged are slow to regenerate. Alveoli are the sacs in the lungs that take up the oxygen from the inspirited air and then transfers it to the tissue.
