Verified step by step guidance

Step 1: Begin by understanding the context of the question. Sensory receptors are specialized cells that detect stimuli such as light, sound, touch, taste, and smell. These receptors are distributed throughout the body but are concentrated in certain organs.

Step 2: Recall that sensory receptors in the skin are responsible for detecting touch, pressure, temperature, and pain. While the skin has many receptors, it does not account for 70% of all sensory receptors.

Step 3: Consider the tongue, which contains taste buds responsible for detecting taste. While the tongue has sensory receptors, it does not have the majority of sensory receptors in the body.

Step 4: Evaluate the ears, which house sensory receptors for hearing and balance. These receptors are important but do not make up 70% of all sensory receptors.

Step 5: Focus on the eyes, which contain photoreceptors (rods and cones) responsible for detecting light and enabling vision. The eyes are densely packed with sensory receptors, accounting for approximately 70% of all sensory receptors in the body.
