Answer:
Combustion of a substance
Explanation:
Johann Becher in 1669 proposed that all the material are composed of the rocks, water and the oils present in the Earth.
When the material is burned, the oil present in the material which is responsible for the combustion. The oil is escaped into the atmosphere which is released through fire and flames are the signs that it is releasing.
In 1703, George Sthal renamed this combustible component called the "Phlogiston" which is taken from the Greek language to refer in flame.
Therefore, phlogiston is responsible for the combustion of a substance.
Temperature
The body must maintain a relatively constant temperature. If it gets too hot, the body employs vasodilation to cool down. This dilates the blood vessels, allowing more heat to escape from them through the skin.
Glucose
The body must regulate glucose levels to stay healthy. When glucose levels become too high, the body releases a hormone called insulin. When they become too low, the body converts the glycogen in the blood to glucose.
Toxins
Toxins in the blood can disrupt the body's homeostasis. Thus, it signals the urinary system to ensure that the toxins are excreted.
Blood Pressure
The body must maintain healthy levels of blood pressure. To do so, the brain sends signals to the heart to speed up or slow down according to the blood pressure.
pH
The lungs control the pH amount in the body. If pH levels become unbalanced, the lungs push more or less carbon dioxide out of the diaphragm. This can raise or lower pH levels in the body.
