Steven Spielberg returns to executive produce the long-awaited next installment of his groundbreaking Jurassic Park series, Jurassic World. Colin Trevorrow directs the epic action-adventure based on the novel âJurassic Parkâ by Michael Crichton.
The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. In air-breathing vertebrates like human beings, respiration takes place in the respiratory organs called lungs.
The lungs are a pair of organs in the chest that are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Air enters the body via the nose (preferably) or the mouth. The air enters the main windpipe, called the trachea, and continues en route to each lung via either the right or left bronchus (plural=bronchi). The lungs are separated into sections called lobes, two on the left and three on the right.
