Human Lungs:
Respiration is powered by different strong structures in different species. In humans, the primary respiratory muscle that drives breathing is the stomach.conceivable.
Lung tissue can be affected by various diseases, including pneumonia and lung cancer. . Illnesses such as bronchitis can also affect the airways. Medical terms identified with lungs begin with pero , from Latin pulmonary lung as in pulmonology, or pneumonia "lung"as in pneumonia.
During embryonic improvement, the lungs begin to form as an outgrowth of the foregut, a tube that continues to form the upper part of a structure related to the stomach. While the lungs are forming, the baby is held in a fluid-filled amniotic sac and cannot break free. Too, blood is drained from the lungs via the ductus arteriosus During labor, in any case, air begins to pass through the lungs and the outflow tract closes to allow the lungs to begin breathing. The lungs are completely formed in early youth.
Humans have two lungs, a right lung and a left lung. They are located in the thoracic cavity of the chest. The right lung is larger than the left, which shares chest space with the heart. The lungs together weigh approximately 1.3 kilograms , with the right being heavier. The lungs are part of the lower respiratory tract, which begins in the trachea and branches into the bronchi and bronchioles, into which inhaled air enters through the conductive zone. The conducting zone ends at the terminal bronchioles.. This sac also divides each lung into sections called lobes. The right lung has three lobes and the left two. The lobes are further divided into bronchopulmonary segments and lobes.
