The body sense organs

We use our eyes as a sense organ for vision. By using our eyes we are able to see and differentiate sizes, colors and shapes of various organisms and hence we can learn about them.

We use ears for hearing receptors are sensitive to sound variations. This proves how your ears are very important organs in scientific studies because they are used to identify and differentiate sounds of various living organisms.

We use nose for smell in order to identify and distinguish between various things.

We use tongue to taste various things. By use of tongue, we can differentiate various tastes and be able to discover the type of the taste concerned. For example, one can differentiate salt from sugar solutions by just tasting using the tongue.

We can use the skin as a sense organ to detect heat, temperature, pressure and even pain. For example, during a hot day you feel hot while during cold days you feel cold.

Measurements: When carrying out biological investigation measurements like mass, time, temperature, and length are unavoidable.
