Exercise 12

The normal composition of feces includes all of the following except:

A. Bacteria

B. Blood

C. Electrolytes

D. Water

Step 1 of 2

The waste product of the digestive process is called feces and it is also known as stool.

• The digestion starts in the mouth and stops in the small intestine.

• Large intestine reabsorbs the water and nutrients in the undigested material and the bowel movement occurs through the anus.

• Feces vary in size, color and texture.

• Normal feces comprises of bacteria, electrolyte and water.

o Bacteria like streptococci, coli bacteria are present in intestine for degradation purpose. They are excreted in feces also.

o Electrolytes are present in the ingested foods and also in digested wastes.

o Water is the normal composition of feces.

Therefore, normal composition of feces does not contain “blood”. Hence, the correct answer is option.
