The lining of the colon is different from the small intestine in that there exists a large number of mucous cells that do not secrete enzymes but rather mucous. The mucous helps protect the wall from the bacterial fermentation inside. About 1.5 L of liquid digestive contents, chyme, pass into the colon.
One important difference between communicable and non-communicable disease is that non-communicable diseases tend to be chronic, which means they last a long time and progress slowly. Communicable diseases are more likely to be acute, which means the disease develops quickly.
List of Non-communicable Diseases. An NCD or non-communicable disease is a disease that is not infectious and cannot be transferred to others. Some of these are diseases that progress slowly or cause chronic symptoms while others progress very rapidly.isk Factors of NCD: Some risk factors of non-communicable diseases include the environment, lifestyle or background such as the genetics, age, exposure to air pollution or gender of a person.
