CIRCULATORY  SYSTEM

Is an organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The study of the blood flow is called hemodynamics


TYPES OF DISEASES
-ARRHYTHMIA/DYSRHYTHMIA: Abnormal heart rates and rhythms all have special names like ventricular tachycardia, fibrillation, but generically are termed arrhythmias or dysrhythmia, meaning “no rhythm” and “abnormal rhythm.
-ISCHEMIA: Sometimes the heart muscle is not getting enough blood flow, more importantly, the oxygen the blood carries is insufficient to sustain muscle which has a very high metabolic rate, and oxygen demand.
-ANGINA PECTORIS: Literally, “pain in the chest.” But, this is a special kind of pain associated with the heart and is distinctive as “crushing, vise-like”, and often accompanied by shortness of breath, fatigue and nausea. 
-ATHEROESCLOROSIS: Literally, “hardening of the fatty stuff.” High fat diets can lead to formation of fatty plaques lining blood vessels. These fatty areas can become calcified and hard leading to arteriosclerosis, hardening of the arteries. When blood vessels become less stretchable, blood pressure rises and can result in heart and kidney damage and strokes. 


CAUSES WHY THEY APPEAR?
These ones depende on the type of disease you have, for example, if you have anemia:  condition in which the red blood cells (erythrocytes) are reduced in number or volume or are deficient in hemoglobin, their oxygen-carrying pigment. The most noticeable outward symptom of anemia is usually pallor of the skin, mucous membranes, and nail beds. 
Because of the symphtoms you will notice the type of circulatory system disease you have.


HOW TO TREAT THEM?
Follow a healthy diet, be physically active, maintain a healthy weight...


HOW TO AVOID THEM?
By doing exercise, quit smoking, control acohol, stay away from stress, take proper rest.

If the muscles around your knee, for example, get weak, you may be more likely to injure that knee. Strong muscles also help you keep your balance, so you are less likely to slip or fall.

DIGESTIVE SYSTEM The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract. TYPES OF DISEASES: 1. GASTROESOPHAGEAL REFLUX DISEASE (GERD): happens when stomach acids are allowed to back up and flow into the esophagus. TREATMENTS: Antacids that neutralize stomach acid, medications to reduce acid production, medications that block acid production and heal the esophagus, etc. HOW TO AVOID IT: Lose weight, avoid foods known to cause reflux, don't lie down after eating... 2. DIVERTICULITIS: happens when the small pouches lining the large intestine become infected and inflamed. TREATMENTS: Medicines such as antibiotics and pain relievers, changes in diet, starting with a clear-liquid or bland diet that is low in fiber until the pain goes away, then increasing the amount of fiber, etc. HOS TO A...

RESPIRATORY SYSTEM I s a biological system consisting of specific organs and structures used for the process of respiration in an  organism. TYPES OF DISEASES: -PNEUMOCONIOSIS: an abnormal condition of dust in the lungs -CYSTIC FIBROSIS:  an inheritable disease tahat affects not only the lungs but other systems producing mucous suchs as the digestive system EMPHYSEMA: Chronic Obstructive Pulmonary Disease, of wich emphysemia is one of, results in progressive destruction of the air sacs in the lungs and loss of respiratory membrane for oxygen exchange. -PULMONOLOGIST: a physician specializing in diseases of the lungs.  -ENDOTRACHEAL INTUBATION: consists of passing a special air-tube into the trachea so oxygen can be reliably supplied directly to the lungs without risk of inhaling vomit from the stomach. CAUSES OF WHY WE HAVE RESPIRATORY DISEASES Asthma, Chronic Obstructive Pulmonary Disease, Chronic bronchitis, Emphysema, Acute bronchitis... HOW TO TREAT THEM? Gargl...
