Which of the following indicates the function of sodium bicarbonate secreted by the pancreas?

A. Sodium bicarbonate is a protease that digests carbohydrates.

B. Sodium bicarbonate stimulates the pyloric sphincter.

C. Sodium bicarbonate inhibits peristalsis.

D. Sodium bicarbonate neutralizes the acidity of chyme.

Answer Explanation:

Sodium bicarbonate neutralizes the acidity of chyme.

The pancreas secretes large amounts of sodium bicarbonate, which protects the duodenum by neutralizing the acid that comes from the stomach.

This compound helps neutralize stomach acid generated during the digestive process.

Choice A is incorrect because sodium bicarbonate is not a protease that digests carbohydrates.

Proteases are enzymes that break down proteins, while sodium bicarbonate is a chemical compound that helps neutralize stomach acid.

Choice B is incorrect because sodium bicarbonate does not stimulate the pyloric sphincter.

The pyloric sphincter is a ring of smooth muscle that separates the stomach from the duodenum and regulates the passage of partially digested food (chyme) into the small intestine.

Choice C is incorrect because sodium bicarbonate does not inhibit peristalsis.

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.

Therefore, the Correct Answer is D.

Q #1: Which of the following substances is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia?

A. Urea

B. Sebum

C. Water

D. Lysozymes

Answer Explanation

Urea is a substance that is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia.

When proteins are broken down, they produce ammonia, which is a highly toxic compound for the body.

Ammonia is then converted into urea and released out of the body through sweat glands.

Choice B.

Sebum is not correct because it is an oily substance secreted by sebaceous glands to lubricate and protect the skin, but it is not related to the breakdown of proteins or the formation of ammonia.

Choice C.

Water is not correct because while it is a component of sweat, it is not specifically related to the breakdown of proteins or the formation of ammonia.

Choice D.

Lysozymes are not correct because they are enzymes found in tears, saliva and other body fluids that have antibacterial properties, but they are not related to the breakdown of proteins or the formation of ammonia.
Q #2: The pleura is a connective tissue sheath that covers which of the following organs?  

A. Liver

B. Heart.

C. Spleen

D. Lung

Answer Explanation

The pleura is a double-layered serous membrane that covers each lung and lines the thoracic cage

The pleura is a vital part of the respiratory tract.

Its role is to cushion the lung and reduce any friction that may develop between the lung, rib cage, and chest cavity.

Each pleura (there are two) consists of a two-layered membrane that covers each lung.

The layers are separated by a small amount of viscous (thick) lubricant known as pleural fluid.

The pleura is comprised of two distinct layers: the visceral pleura and the parietal pleura.

The visceral pleura is the thin, slippery membrane that covers the surface of the lungs and dips into the areas separating the different lobes of the lungs (called the hilum).
Q #3: Which of the following summarizes a change that takes place as a solid turns to a liquid?  

A. Particles become less ordered.

B. Particles have a decrease in mobility.

C. Particles move closer together

D. Intermolecular forces between particles become stronger.

Answer Explanation

As a solid turns to a liquid, the particles become less ordered and more free to move around.

Choice B is not correct because particles have an increase in mobility as a solid turns to a liquid.

Choice C is not correct because particles move further apart as a solid turns to a liquid.

Choice D is not correct because intermolecular forces between particles become weaker as a solid turns to a liquid.
