They can make incoming air warm and moist, in order to protect the delicate cells of the inner respiratory passages.But, the diaphragm is not alone.
Tiny hairs, called cilia, along your air passages move in a sweeping motion to keep the passages clean. The bronchioles end in tiny balloon-like air sacs called alveoli. The left lung is smaller than the right due to the location of the The organs described above work as a functional unit within the respiratory system.

Biology is brought to you with support from the. The first is the series of conducting tubes that carry air from the atmosphere towards the lungs. In humans and other mammals, there is an extensive, highly vascularized The primary function of the respiratory system is gas exchange. This can lead to health problems like Cells in your trachea and bronchial tubes make mucus that keeps air passages moist and helps keep things like dust, bacteria and viruses, and Mucus can bring up things that reach deeper into your lungs. Air is taken in through the mouth and nose. The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. Respiratory system definition, the system by which oxygen is taken into the body and an exchange of oxygen and carbon dioxide takes place; in mammals the system includes the nasal passages, pharynx, trachea, bronchi, and lungs. The viruses usually establish contact with the cells of the nose, which then produce a clear liquid to trap these microorganisms and expel them from the body. Multiple conditions can cause one or both of these problems. They also activate hormones and either remove or add to the substances circulating in the blood.
The nose is a structure of the face made of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity.

Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed, according to the American Lung Association. Respiratory system definition, the system by which oxygen is taken into the body and an exchange of oxygen and carbon dioxide takes place; in mammals the system includes the nasal passages, pharynx, trachea, bronchi, and lungs.
Lungs are made of spongy tissue containing many vascular tissues and much of the airway that appears after the trachea. Donate or volunteer today! Respiratory failure is the inability of the respiratory system to adequately supply fresh oxygen or remove carbon dioxide, resulting in low blood oxygen or high blood carbon dioxide levels, respectively. Asthma. A pleural membrane allows these paired organs to expand and contract with minimal friction. "American Medical Association: "Respiratory System: Basic Function.
Our respiratory system is a very precious piece of complex machinery designed for the easy usage of the air around us to provide free breathing and good health.
