Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.

The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.

Goshia [24]

Answer:

The correct answer is 327.78.

Explanation:

A mortality rate refers to the determination of the rate of the occurrences of deaths in a given population in the course of a particular time period. The formula for finding the mortality rate is:  

Deaths taking place in a given time duration / the size of the populace among which the deaths have taken place × 10ⁿ

The given population of the country is 250 million

The number of individuals died due to a certain disease is 819450

Thus, the mortality rate per 100000 can be calculated as:  

819450 / 250000000 × 100000 = 327.78 deaths per 100,000 people.
