Why are the contents of gastric juice so hostile to the exposed duodenal wall?

Biology

lesya692 [45]3 years ago

Gastric juice  is a thin strongly acidic (pH 1 - 3 ) almost colorless liquid secreted by the glands in the stomach lining. It is made acidic by one of its constituents namely hydrochloric acid. It is because of its acidic nature that gastric juice can be  so corrosive to the lining of the duodenum.

The integrity of the inner lining of the (mucosa) of the duodenum depends on a careful balance of the "aggressive" factors (such as acid) and "defensive" factors (such as mucus) which helps to protect the delicate surface lining.

Disruption of this balance caused by too much acid (or weakened defense ) can result in erosions or ulcers .

Helen [10]

slab pull

Explanation:

When the more dense crust dives into the asthenosphere, it continues to pull the rest of the crust with it. This is called slab pull.

The pulling effect of a subducting plate on the rest of the plate is known as slab pull.

  • In describing plate tectonics and movement of different plates, the term slab pull is frequently used.
  • It is used to illustrate the dragging of a plate mass on all its part.
  • A slab is a lithospheric plate.
  • At a subduction margin, colder plates will sink because they are more denser.
  • The whole mass of the plate moves down regardless of how rigid and brittle they are.

1. Suppose that a sample of beef broth initially contains
iren [92.7K]

From the calculations, the rate of growth of the culture is 2.88.

<h3>What is exponential growth problem?</h3>

We apply the exponential growth problem when there is an exponential increase.

Thus, we have; P =Poe^rt

P = amount at time t

Po = amount originally present

t = time taken

r = rate of growth

1.6 × 10^6 = 16e^4r

1.6 × 10^6/16 = e^4r

1.0 * 10^5 =  e^4r

ln 1.0 * 10^5 = ln e^4r

11.5 = 4r

r = 11.5/4

r = 2.88
