Question

a team of international researchers discovered a hidden sensory _________ located throughout the blood vessels and sweat glands.

organ
receptor
limit
system

Explanation:

Analyze the sentence context

The sentence describes a discovery of a "hidden sensory ________" located throughout blood vessels and sweat glands.

Evaluate the options

• organ: A self-contained group of tissues with a specific function. A sensory organ (like the eye or ear) is localized, not distributed "throughout" blood vessels and sweat glands.
• receptor: Sensory receptors (such as thermoreceptors or mechanoreceptors) are specialized structures or nerve endings distributed throughout tissues, including blood vessels and sweat glands, to detect stimuli.
• limit: Does not fit the biological context.
• system: A group of organs working together. While the somatosensory system includes these, the specific discovery of hidden sensory structures in these tissues refers to "receptors" (specifically, researchers discovered a network of sensory nerve endings/receptors).

Select the correct term

The term "sensory receptor" fits the biological description of structures distributed throughout blood vessels and sweat glands to detect physiological changes.

Answer:

• organ
• receptor (Correct answer)
• limit
• system
