Verified step by step guidance

Step 1: Understand the role of sensory receptors in the body. Sensory receptors are specialized cells that detect specific types of stimuli and send signals to the nervous system for interpretation.

Step 2: Review the types of sensory receptors. Mechanoreceptors detect physical changes like pressure or stretch, photoreceptors detect light, thermoreceptors detect temperature changes, and chemoreceptors detect chemical changes in the environment.

Step 3: Focus on the problem's context: blood ion concentration. Blood ion concentration refers to the levels of ions like sodium, potassium, calcium, and hydrogen in the bloodstream, which are chemical stimuli.

Step 4: Identify the sensory receptor that responds to chemical stimuli. Chemoreceptors are specialized to detect changes in chemical composition, such as blood ion concentration, pH, and oxygen levels.

Step 5: Conclude that chemoreceptors are the correct type of sensory receptor for detecting changes in blood ion concentration, as they are specifically designed to monitor chemical changes in the body.
