Effective Functions Of The Respiratory System

Effective Functions Of The Respiratory System

The respiratory system operates in the same capacity as the cardiovascular system in that they both supply oxygen to and expel carbon dioxide from the body.

Oxygen is vital because it provides the fuel for all the body's function. The respiratory system also removes toxic waste from the body, regulates the bodies temperature and ensures the stability of the blood's acid- alkaline balance.

Divided into upper and lower respiratory systems, the upper consist of the nose and throat; the lower refers to larynx, trachea,bronchi and lungs.

The inner surface area of the lungs is approximately thirty five times larger than the surface area of your skin. This huge surface allows the body to properly absorb oxygen and expel carbon dioxide.

Breathing begins in the nose, which alerts you to potentially toxic smells. The nose also warms and filters the air which enters the body, and in turn brings out or expels airborne germs which can get trapped in the mucous membranes.

The air passes through the throat and enters the trachea through the larynx. The trachea and bronchial tubes channels air into the lungs, and protect them from unwanted germs particles which become ensnared in their mucous membranes. Before inhalation begins, the air pressure inside the lungs is equal to the atmospheric pressure outside the body. When the diaphragm contracts to increase the volume of the lungs, the pressure inside the lungs drops and air rushes in until the pressure is equal again.

Exhalation begins when the respiratory muscles relax, the diaphragm pushes up towards the lungs and the surface tension of the lungs pulls inwards, decreasing lung volume and pushing air out.

Blood and air exchange oxygen and carbon dioxide through the membrane of the bronchial tubes, in the bronchioles, alveolar, ducts and alveoli. The blood now enriched with oxygen returns to the heart to be pumped through the rest of the body.

A lack of iron or lack of blood in the body causes insufficient oxygen to be transported to the cells, resulting in symptoms of lack of adequate breathe , weakness of the body, coughing and fatigue. That is why you need to nourish your respiratory system the needed supplement to keep your systems working effectively.
