State three reflex action of the body.explain how the are in the same in all of them
Answers
Reflex actions are basically those actions which a person does unintentionally. The body does it, on its own, because that's how the natural defense mechanism works in a body.
Following are some examples of reflex actions:
1) Contraction of the pupils when exposed to light. This happens because the human eye is sensitive to direct light. Thus when exposed to harsh direct light the human eye has a self mechanism of closing itself, and the contraction of pupils as well.
2) Sneezing is also a reflex action on part of the nose when it gets irritated. Generally, the irritation is tracked and sneezing is a reflex of letting out all odd substances or trying to eliminate cause of irritation.
3) Lacrimal reflex is also a type of reflex related to the eyes. In this tears are produced to clear objects from the eye.
Whats common in all of them is that they all are defense mechanisms into something disturbing the senses or organs or the body itself.
