The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.
The respiratory system, which includes air passages, pulmonary vessels, the lungs and breathing muscles, aids the body in the exchange of gases between the air and blood, and between the blood and the body's billions of cells.

This image shows the intentional draining of a large suprachoroidal hemorrhage! This condition involves a bleed into the space between the choroid and sclera from a ruptured posterior ciliary artery. If sufficiently severe it may result in spilling of intraocular contents. It is a dreaded complication of cataract surgery, but extremely rare (0.04%) with modern surgical techniques. The visual prognosis of large bleeds such as this one is highly variable, and is dependent on the degree to which the vitreous and retina are affected.
