Pleura Definition
The pleura is a thin membrane that lines the inside of the chest cavity and covers the lungs. It helps keep the lungs moist and allows them to slide easily over each other as you breathe.
Lungs
are a pair of organs in the chest that help you breathe. They take in oxygen from the air and put it into your bloodstream. They also take carbon dioxide out of your bloodstream and put it into the air.
The Function of Pleural Fluid
The pleural fluid is a thick, lubricating fluid that coats the inside of the chest cavity and the lungs. It helps to reduce friction between the lungs and the chest wall and helps the lungs to expand and contract as you breathe. The pleural fluid also contains white blood cells and other proteins that help to fight infection.
Structure of Lungs
The lungs are two spongy organs in the chest that are responsible for taking in oxygen from the air and releasing carbon dioxide. The left lung is smaller than the right lung because the heart takes up space on the left side of the chest. The lungs are divided into lobes, and each lobe is divided into smaller segments. The lungs are surrounded by a thin membrane called the pleura. The pleura line the lungs and the inside of the chest wall.
Steps Involved in Respiration
The process of respiration begins with the inhalation of oxygen from the air into the lungs. The oxygen then transported by the blood to the cells of the body where it used to produce energy. The waste product of this process is carbon dioxide which is then exhaled from the body.
