The brain is dependent on the lungs because the lungs are responsible for providing oxygen to the brain. The brain requires oxygen to function properly and to carry out its various functions, including thinking, learning, and controlling the body. Without oxygen, the brain would not be able to function properly and could lead to serious health problems.
The lungs work to take in oxygen from the air and transport it to the blood circulation system, where it is then carried to the brain and other parts of the body. The heart then pumps the oxygenated blood throughout the body, including the brain. Without this constant supply of oxygen, the brain would not be able to function properly, leading to symptoms such as dizziness, fatigue, and confusion.
So, the brain is dependent on the lungs to provide the oxygen it needs to function properly, and without this constant supply, the brain would not be able to function normally.
