Respiratory and Circulatory Systems working with other Organ Systems

Air enters the body through the nose, nasal passages, and then through the windpipe or trachea, which divides into two branches, called bronchial tubes or bronchi. The bronchi subdivide many times inside the lungs. forming the hair-like tubes called bronchioles. At the end of the bronchioles are tiny bubble-like structures called alveoli.

When you breathe in or inhale, the diaphragmri muscle contracts. When you breathe out or exhale, the diaphragm muscle relaxes. The diaphragm helps the air go in and out of the lungs.

Air first enters your lungs and then into the left part of your heart. It is then pumped by your heart into the bloodstream, all the way through your body. Once it reaches the cells, oxygen processes the nutrients to release energy. Carbon dioxide is the waste material given off during this process. The blood delivers carbon dioxide into the right portion of your heart, from which it is pumped to the lungs. Carbon dioxide leaves your body through the lungs when you exhale.

The heart is a hollow muscular organ, about the size of your fist, which is located in the center of your chest between the lungs. It is a double pump that pumps on the left and right sides. Each side is divided across into two chambers. The top chamber is called the atrium. The bottom chamber is called the ventricle. The valve acts as a one-way door, allowing blood to flow either forward into the next chamber, or out of the heart.

Heart rate or pulse is the number of times your heart beats in a minute

(BPM or beats per minute). When you are resting, your heart rate slows down, as your body does not need as much oxygen as it does when you exercise.

Cigarette smoking harms nearly every organ in the body, causing many illnesses and affecting health in general. The negative effects of smoking on the circulatory system include increased heart rate and blood pressure, coronary heart disease, arteriosclerosis, and vascular diseases. The respiratory diseases caused by smoking are chronic bronchitis, emphysema, asthma, cough, colds, tuberculosis, lung cancer, and other respiratory infections.

The best way to prevent diseases in the respiratory and circulatory systems is to have a healthy lifestyle, which includes balanced diet, regular exercise, adequate rest, proper hygiene, and avoiding vices such as cigarette smoking and alcohol drinking. Circulatory and respiratory disease can easily be detected with regular health check-up and physical screening.
