• A. Thyroxin
• B. Adrenaline
• C. Pancreatin
• D. Gastrin

Answer 1

The correct option is B

Adrenaline

The correct option is B.

Explanation of the correct option:

1. The body releases the hormone adrenaline when you're furious, terrified, or enthusiastic.
2. The heart and lungs breathe more easily and quickly while you're under the effects of adrenaline.
3. It boosts blood pressure, sharpens your mind, makes your blood sugar levels higher in the blood to give you energy, and causes the blood vessels to send more blood to the brain and muscles.
4. The inner portion of an adrenal gland called the adrenal medulla regulates the hormones that start the flight or fight response.
5. Both epinephrine (adrenaline) and norepinephrine (noradrenaline), which have comparable roles, are the primary hormones released by the adrenal medulla.

Explanation of the incorrect options:

Option A:

1. T4 is another name for the thyroid hormone thyroxine.
2. The amount of T4 in your blood is determined by a T4 test.
3. Thyroid illness may be indicated by excessive or insufficient T4 levels.

Option C:

1. A collection of digestive enzymes is called pancreatin (proteins).
2. These enzymes are crucial for the digestion of fats, proteins, and carbohydrates and are typically generated by the pancreas.

Option D:

1. G cells in the duodenum and the pyloric antrum of the stomach create the linear peptide hormone known as gastrin.
2. The primary functions of the peptide hormone gastrin are to promote gastric mucosal development, gastric motility, and hydrochloric acid (HCl) secretion into the stomach.

Final answer: The hormone that increases the rate of heartbeat and blood pressure after shock in a person is adrenaline.
