The retina detects light and the optical nerve sends the signal to the brain.
Hypothalamus
medulla oblogata
The adrenal and pituitary glands put out the hormones aldosterone and vasopressin, respectively, and these hormones control the way the kidneys (organs) maintain the correct levels of sodium and water in the body.
The medulla oblongata and the pons are the parts of the brain that control breathing. The medulla oblongata detects oxygen and carbon dioxide levels and controls the muscles in the heart, lungs, and diaphragm. The pons controls inhalation and exhalation speed.
The part of the brain that regulates water balance also regulates body temperature. This part of the brain is called the hypothalamus.
There is a part of the brain called the medulla oblongata which detects increased carbon dioxide levels in the blood and triggers the breathing reflex. Breathing then allows the excess carbon dioxide to escape by way of the lungs, as oxygen is acquired.
Hypoxemia (low oxygen levels in the blood) will affect the entire brain.
