Answer:
peristalsis.
Explanation:
When the food enters the esophagus, it is in the form of a bolus. During this esophageal stage of swallowing, there are rhythmic contractions and relaxation of the circular and longitudinal layers of the muscularis of the GI tract. It is called peristalsis. This pushes the bolus downwards. Peristalsis in the esophagus is controlled by the medulla oblongata.
As the food enters the stomach, waves of peristalsis pass over the stomach every 15 to 25 seconds. The peristaltic waves in the stomach start at its body and become more intense as they reach the antrum. It moves gastric contents from the body of the stomach down into the antrum, a process known as propulsion.
<span>The cytoskeleton is a
structure found in the cytoplasm that is composed of a web of proteins. It is a
network composed of protein microfilaments, intermediate
filaments, and microtubules. They can be found in all living organisms and are
responsible for giving them their distinct cell shapes and coherence.
Aside from
providing the cell shape, the cytoskeleton is also responsible for cell
movement, organelle movement, and cell division.</span>
<span>It plays a crucial role in
cell division because they provide the movement of chromosomes to the daughter
nucleus. The absence of these protein filaments would result to different
abnormalities and diseases in the genes. </span>
