The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

Ciliated Pseudostratified Columnar Epithelium
The trachea (windpipe) is the large tube that delivers air to the bronchi from the upper respiratory tract. It warms and moisturizes the air and catches debris and microbes before entering the lungs. Lining the trachea are mucosal membranes comprised of epithelial cells, mucus-secreting goblet cells, and cilia. It is also traversed by a network of blood vessels and lymphatic vessels.
