Use the following choices to answer questions 31 – 35.
a.) salivary amylase b.) cholesterol c.) pharynx d.) cephalic e.) chyme
31.) |
Food in the stomach is squeezed and mixed with gastric juices, forming a semiliquid called. |
32.) |
_____ is an essential component of plasma membranes, can be modified to form bile salts and steroids such as sex hormones. |
33.) |
The _______ phase occurs before food enters the stomach and is triggered by aroma, sight, and thought. |
34.) |
The digestive function performed by ____________ is to start digestion of carbohydrates. |
35.) |
Deglutition is the function of the _________. |
31)The answer is chyme.
Relaxation or contraction of smooth muscle mixes stomach contents
and this partially digested food and juice mixture is called
chyme.
32) The answer is cholesterol.
Cholesterol plays role in synthesising steroid hormone like
aldosterone which are involved in osmotegulation .They are the
precursor to bile salts which helps in emulsification of fat and
their absorption.
33)The answer is cephalic phase which is initiated by
sight,aroma,thought or taste of food.
Neurological signals originate from cerebral cortex. And also from
the apetite centres in amygdala and hypothalamus.
34)Salivary amylase.
The salivary gland in the oral cavity secrete saliva that coats the
food particles. This saliva contains salivary amylase.
35) The answer is pharynx.
Deglutition is a mechanism by which food is pushed from oral cavity
into esophagus and then pushed to stomach. This movement is by
pushing called propulsion.
