Answer:
A) areolar tissue soaks up excess fluid in an inflamed area
Explanation:
Areolar tissue is found around blood vessels, muscles, nerve bundles. Edema which is also a part of inflammation occurs when blood capillaries of blood vessels leak the fluid and is soaked by areolar tissue. So excess fluid in these tissue cause swelling of that part.
Edema is one type of defense reaction to the cell injury. With fluid white blood cells and defense proteins move in the area and counter the infectious agent of injury and helps in eliminating the injurious factor. So the correct answer is A.
The pH of stomach is important as it helps to induce the digestive enzyme called pepsin. The presence of HCL i.e., hydrochloric acids in stomach results in the pH of stomach to become acidic which range from 1.5 to 6.5 values.
<h3>What is the pH level of stomach?</h3>
When the bolus enters the stomach, it aids the release of gastric juice having enzymes, mucous and HCL.
The upper and lower parts of stomach have varying pH values. Upper part has a pH of 4−6.5, while the lower part is with a pH of 1.5−4.0 which is highly acidic due to HCL.
Thus, the relative pH of stomach is acidic ranging from value 1.5 to 6.5.
