exchange

Explanation:

Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.

Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.

Answer:

The correct option is: a deficiency of dopamine in the substantia nigra.

Explanation:

The substantia nigra is the principal site involved in the physiopathology of Parkinson´s disease.

Cells from this area degenerate and die progressively causing important degeneration in the central nervous system. The cells that die -with no known reason- are those that produce dopamine and proportionate dopaminergic innervation to the encephalon. In fact, almost all the symptoms exhibited by patients with the disease can be explained by the lack of dopamine in the substantia nigra.

This area uses the neurotransmitter to communicate neurons from the base ganglia. Ganglia are responsible of modulating and modifying movements.

The nigrostriatal system participates in planning and automatic execution of learned movements. When the ganglia activity decreases, so it does the amount and velocity of movements, something typical of the disease.
