Multiple Choice

What is the primary role of nervous tissue in the heart?

To provide structural support to cardiac muscle cells

To produce hormones that control blood pressure

To regulate the heart's rate and coordinate contractions

To store oxygen for cardiac metabolism

Verified step by step guidance

Step 1: Understand the role of nervous tissue in the heart. Nervous tissue is responsible for transmitting electrical signals that regulate the heart's activity, including its rate and rhythm.

Step 2: Recognize that structural support for cardiac muscle cells is provided by connective tissue, not nervous tissue. This eliminates the first option.

Step 3: Note that hormone production related to blood pressure is primarily the role of endocrine organs like the adrenal glands, not nervous tissue. This eliminates the second option.

Step 4: Understand that oxygen storage for cardiac metabolism is not a function of nervous tissue. Oxygen is stored and transported by hemoglobin in red blood cells, not nervous tissue. This eliminates the fourth option.

Step 5: Conclude that the primary role of nervous tissue in the heart is to regulate the heart's rate and coordinate contractions, as it ensures the synchronized pumping action of the heart chambers.
