LUNGS AND ITS STRUCTURE, BLOOD CIRCULATION IN THE LUNGS

Abstract

Human and animals living on land take in oxygen from the air using their respiratory organs and release carbon dioxide through their respiratory organs. The human respiratory system consists of the nasal cavity, larynx, trachea, bronchus and lungs. These are usually the airways that deliver oxygen to the alveoli of the lungs. This article provides information about the structure of the lungs and blood circulation in the lungs.
