RESPIRATORY SYSTEM
A complete, schematic view of the human respiratory system with their parts and functions. Latin:
systema respiratorium

The respiratory system (or ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood. COMMON RESPIRATORY DISORDERS

Disorders of the respiratory system can be classified into four general areas: Obstructive conditions (e.g., emphysema, bronchitis, asthma) Restrictive conditions (e.g., fibrosis, sarcoidosis, alveolar damage, pleural effusion) Vascular diseases (e.g., pulmonary edema, pulmonary embolism, pulmonary hypertension) Infectious, environmental and other "diseases" (e.g., pneumonia, tuberculosis, asbestosis, particulate pollutants): Coughing is of major importance, as it is the body's main method to remove dust, mucus, saliva, and other debris from the lungs. Inability to cough can lead to infection. Deep breathing exercises may help keep finer structures of the lungs clear from particulate matter, etc. Chronic Obstructive Pulmonary Disease (COPD) - Irritation of the lungs can lead to asthma, emphysema, and chronic bronchitis and people can develop two or three of these together. Chronic Bronchitis - Any irritant reaching the bronchi and bronchioles will stimulate an increased secretion of mucus. In chronic bronchitis the air passages become clogged with mucus, and this leads to a persistent cough. Emphysema - The delicate walls of the alveoli break down, reducing the gas exchange area of the lungs. The condition develops slowly and is seldom a direct cause of death. Asthma - Periodic constriction of the bronchi and bronchioles makes it more difficult to breathe. Pneumonia - An infection of the alveoli. It can be caused by many kinds of both bacteria and viruses. Tissue fluids accumulate in the alveoli reducing the surface area exposed to air. If enough alveoli are affected, the patient may need supplemental oxygen. REPRODUCTIVE SYSTEM

The reproductive system or genital system is a system of sex organs within an organism which work together for the purpose of reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring. COMMON AILMENTS OF REPRODUCTIVE SYSTEM

Proper care  must be observed to avoid ailments of the reproductive system. Some of the common ailments of the reproductive system are: Ailments of the Male Reproductive System
1.       Epididymitis  is characterized by swelling, pain and fever. It worsens by physical activities. 2.       Hydrocele may develop at any age. It causes little or no pain. It is the accumulation of a watery, light – yellow colored liquid in the scrotum. 3.       Orchitis is caused by injuries, tuberculosis or mumps. It is an inflammation of the testes. It may cause sterility. a.       Syphilis are painless sores. They disappear within a week. But if not treated, heart, brain or eye damage may result. b.      Gonorrhea is an infection of the urethra. Symptoms are itching of the urethra, burning sensation when urinating and thick yellow discharge. Ailments of the Female Reproductive System
