The answer is reflexes. Reflexes are usually involuntary muscle movements that happen almost instantaneously in response to stimuli. A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain. It is a survival mechanism evolved by the body used in the objective to escape danger.
DNA in prokaryotes frees in the cytoplasm, while in eukaryotes (like humans) DNA is in the nucleus.
Human DNA is found in the cells that make up your tissues and organs: nerve cells, liver cells (liver), skin cells ... They are extremely numerous, more than 50 000 billion and have very diversified functions! Most of our cells are microscopic (20 to 30 micrometers) and contain an even smaller nucleus structure.
Each nucleus contains the genetic material of the cell, the chromosomes.
Mitochondrial DNA can also be found in mitochondria, but mitochondria are much smaller than nuclear DNA.

Answer:
The most important are the lungs, more precisely the alveoli.
Explanation:
Alveoli are structures of the lungs where gas exchange occurs. They allow oxygen from the air to pass into blood. Oxygen diffuses through the walls of alveoli into the capillaries that surround it. Oxygen is then bonded with the iron in red blood cells and travels to the heart. The heart then sends the oxygenated blood out to all the cells in the body.
