Lungs: helps you breath and respiration. In humans the lungs occupy a large portion of the chest cavity from the collarbone down to the diaphragm, a dome-shaped sheet of muscle that walls off the chest cavity from the abdominal cavity. At birth the lungs are pink, but as a person ages, they become gray and mottled from tiny particles breathed in with the air. A person has two lungs in the body but he/she can survive with only one.

Liver: largest internal organ of the human body. The liver, which is part of the digestive system, performs more than 500 different functions, all of which are essential to life. Its essential functions include helping the body to digest fats, storing reserves of nutrients, filtering poisons and wastes from the blood, synthesizing a variety of proteins, and regulating the levels of many chemicals found in the bloodstream. The liver is unique among the body’s vital organs in that it can regenerate, or grow back, cells that have been destroyed by some short-term injury or disease. But if the liver is damaged repeatedly over a long period of time, it may undergo irreversible changes that permanently interfere with function.

Common Human Deceases

Diabetes, High Cholesterol, High Blood Pressure, Asthma, Osteoporosis, Cancer

Diabetes: Sugar decease is another problem in people. Body has sugar in the system. If more sugar goes in your body then it requires then person gets diabetic patient.

High Cholesterol: a complex alcohol constituent of all animal fats and oils. It can be activated to form vitamin D. Cholesterol is one of a group of compounds known as sterols and is related to such other sterols as the sex hormones and the hormones of the adrenal cortex.
A close relationship exists among levels of blood cholesterol in the body, those of other fats or lipids, and the development of atherosclerosis. In this disorder, plaques containing cholesterol are deposited on the walls of arteries, particularly those of small and medium size, reducing there inside diameter and the flow of blood. Clotting of blood, such as may occur in the coronary arteries to cause a heart attack, is most likely to develop at places where arterial walls are roughened by such plaques.

High Blood Pressure: Hypertension or High Blood Pressure, medical condition in which constricted arterial blood vessels increase the resistance to blood flow, causing an increase in blood pressure against vessel walls. The heart must work harder to pump blood through the narrowed arteries. If the condition persists, damage to the heart and blood vessels is likely, increasing the risk for stroke, heart attack, and kidney or heart failure. Often called the “silent killer,” hypertension usually causes no symptoms until it reaches a life-threatening stage.

Asthma: Asthma is a disease of the bronchial tubes, or airways of the lungs, characterized by tightening of these airways. It is a chronic condition; people with asthma live with it every day and for their whole lives.

Osteoporosis: bone condition characterized by a decrease in mass, resulting in bones that are more porous and more easily fractured than normal bones. Fractures of the wrist, spine, and hip are most common; however, all bones can be affected. White females are the most susceptible, but other risk factors include low calcium, inadequate physical activity, a family history of the disease. It is common to older people.
