What is the typical pH of gastric chyme when it enters the duodenum?
1) 1.0-2.0 (very acidic)
2) 2.0-4.0 (slightly acidic)
3) 4.0-6.0 (weakly acidic)
4) 6.0-8.0 (slightly alkaline)
E) 8.0-10.0 (alkaline)
Gastric chyme, which is the mixture of food and gastric juice, is highly acidic due to the presence of hydrochloric acid secreted by parietal cells. The pH typically ranges from 1.0 to 2.0 when it enters the duodenum. This acidity helps to denature proteins and provides the optimal environment for pepsin activity. Once in the duodenum, the chyme is neutralized by the secretion of bicarbonate from the pancreas and bile from the liver.

Prosthodontics
Answer: 4
Explanation:
It is usually not associated with a sore mouth: This
statement is true. Denture stomatitis can occur without
significant soreness, although some patients may experience discomfort. The
condition is often asymptomatic, especially in its early stages.
It is usually associated with wearing a denture at night:
This statement is true. Wearing dentures continuously,
especially at night, can create a favorable environment for the growth of
Candida species, which is a common cause of denture stomatitis.
It is more common in diabetes: This statement is true.
Individuals with diabetes are at a higher risk for infections, including
oral candidiasis, which can lead to denture stomatitis.
It is more common in men: This statement is not
true. Denture stomatitis is generally more prevalent in women,
particularly postmenopausal women, due to hormonal changes that can affect
oral mucosa and immune response.
