Food is moved through the digestive tract by a sequence of wave-like muscle contractions called peristalsis.

<h3>What is digestive tract?</h3>
  • The digestive system of the human body is made up of the gastrointestinal tract and additional digestive organs (the tongue, salivary glands, pancreas, liver, and gallbladder).
  • In order for food to be absorbed and incorporated into the body, it must first be broken down into smaller and smaller components during digestion.
  • Cephalic, gastric, and intestine phases make up the three stages of the digestive process.
  • Gastric gland secretions in reaction to the sight and smell of food start the initial stage of digestion, known as the cephalic phase.
<h3>What is peristalsis?</h3>
  • Peristalsis is the contraction of the muscles. is the contraction and relaxation of radially symmetric muscles that travels anterogradely down a tube in the form of a wave.
  • In the lining of the gut, a simultaneous contraction of the longitudinal muscle and relaxation of the circular muscle is followed by a coordinated contraction of involuntary circular muscles known as peristalsis.

vredina [299]

A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?

----------------------------------

4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.

---

Solve for "x":

If amount of compound A is 4x = 255

x = 255/4

------------------------------

Then amount of compound B is 5x = 5(255/4) = 318.75 ml
