What you need to know about the human respiratory system is a critical component of every CPR lesson. The basic steps for dealing with a cardiac arrest include recognizing the need for a defibrillator and the need for chest compressions. There are different aspects of the respiratory system, which include breathing, circulation, and elimination of carbon dioxide and carbon monoxide.
The primary function of the respiratory system is to provide oxygen into the body. Breathing is controlled by muscles in the throat, diaphragm, chest, and abdomen. The chest can also be moved up and down as a means of manipulating the airways. Blood can be drawn from the lungs to provide the body with an adequate supply of oxygen.
Each of the major organs of the body has its own mechanism of air and blood movement. The major organs of the respiratory system are the heart, lungs, diaphragm, and the lungs themselves. When oxygen becomes scarce in the body, blood can be supplied through the lungs.
In order to maintain sufficient blood flow throughout the body, the lungs must be able to carry more oxygen than carbon dioxide. This is accomplished through the process of exhalation and expiration. The human body is designed so that we expend a minimum amount of energy in this process. Exhalation is when air is expelled from the lungs and expiration is when the lungs expel all of the carbon dioxide.
The function of the diaphragm is to support the ribs during respiration. With the exception of the throat and the trachea, all of the major tissues in the body are found in the diaphragm. There are different types of diaphragms including the cervical diaphragm, the thoracic diaphragm, the abdominal diaphragm, and the intercostal diaphragm. The lungs are designed to accommodate more lung tissue than any other body part. It takes an average of four hours for a normal adult to exhale all of the lungs’ airway tissue. This process is enhanced during exercise or after strenuous physical activity.
The most important fact about the human respiratory system is that there is an equal distribution of cells in the body. In the case of the heart, blood clot forms in the aorta, which prevents blood from returning to the heart. In order to have blood flow back to the heart, a vascular bed is formed on the heart’s surface.
In the case of the lungs, oxygen combines with oxygen to form carbon dioxide and then with nitrogen to form carbon monoxide. An excellent way to remember this fact is that we use more oxygen than we consume. With this knowledge, it should be fairly easy to design a human respiratory system worksheet for your CPR lessons.
