173) a) upper lip from lower lip
The oral fissure is the horizontal opening that is present between the lipids through which one consumes food and it leads into the oral vestibular
174) a) Philtrum
The Phitrum is fold of mucous membrane and it helps in anchoring the tongue to the floor of the mouth. It is attached to the middle area of the upper lip and extends across the nasal spectrum.
175) Enamel – It is one of the major tissues that make up the tooth in humans. It covers the crown part.
176) (d) They are changed into non toxic compounds by a series of chemical reactions. The liver is the organ which is known for detoxification. As soon as one has a functioning and proper liver, it helps in detoxification process and remove the toxins.
177) b) They change chemically and are in the end products of the reaction
The enzymes are only catalyst and help in accelerating the reaction. It does not participate directly and neither appears at the end products of the reactions.
178) a) Gastric Inhibitory Peptide
The peptide is known to reduce the secretion of stomach acid and in an attempt to do, it helps in protecting the small intestine from the acid damage. It helps in reducing the rate at which food is moved through stomach and helps to restrict GI motility.
179) d) Amylase
Amylase is an enzyme which helps in catalyzing the hydrolysis of the starch into the sugars. It is found in the saliva and this starts the chemical digestion process
