👉 Bird fluid, also known as air sac fluid, is a unique and essential component of avian physiology. Unlike typical bodily fluids, it is not produced by organs but rather derived from the extensive network of air sacs that permeate a bird's body. These air sacs, connected to the lungs and other parts of the respiratory system, allow for a continuous flow of air through the lungs, enhancing oxygen absorption. The fluid itself is essentially a clear, colorless substance that plays a crucial role in maintaining the health of the respiratory system and ensuring efficient gas exchange, which is vital for birds' high metabolic rates and sustained flight capabilities.
