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.
âNon-communicable diseasesâ means which are not spread from one to another but affect health in large numbers causing public health issues. Eg. Ischaemic heart disease(Heart attacks) Diabetes mellitus; Hypertension; Accidents; Suicides; Etc.. Communicable diseases are prevented by good hygiene, good sanitation facilities and improving living standards.
