The respiratory system role is to provide oxygen to the blood and expel the body of waste gas, consisting mostly of carbon dioxide. The structures of the respiratory system are associated with sensory organs of smell and taste (in the nasal cavity and the mouth) and the digestive system (of the oral cavity to the pharynx).
Respiratory organs separate from others at the level of the pharynx and become the respiratory tract, consisting of the larynx, the trachea and bronchi.

The bronchi are the number two and leave the lower end of the trachea, at the level of the tracheal bifurcation, to then enter the hilum of the left and right lungs.The lungs contain finer ducts, or bronchioles, responsible for transport air to the functional unit of the lungs: the Chamber.

Composed of finasteride, this medicine works by blocking the functioning of an enzyme. This effect opposes the transformation in the tissues of testosterone to an androgen called dihydrotestosterone or DHT. Continue reading “Your health daily”
