Imagine two iguanas are in a fight and one iguana gets a cut. This cut leads to a loss of blood resulting in a drop in blood pressure, which could be life-threatening if not corrected. As a result, blood pressure sensors in the heart and some arteries detect the drop in pressure and send signals to the brain. Next, the brain stimulates the release of certain hormones into the blood. The result is that the heart beats more rapidly and raises the blood pressure of the injured iguana back to normal (or to the set point). This is an example of

Summarise the passage to 150 words ANIMAL doctors? Why, that may sound like something out of a child’s storybook. Yet it is a fact that many animals are quite successful when it comes to treating their ailments. And they do this in ways that frequently prove to be more effective than those used by man. Yes, animals have been endowed with an instinctive ability to treat themselves when they have certain afflictions.Archibald Rutledge, a writer and naturalist, recalls that when he was a plantation boy he kept many wild animals as pets, one of them being a little white-tailed deer. One day he found that his pet had torn a nasty gash in its side on a barbed-wire fence. To help heal the wound, he cleansed it and carefully bandaged it.However, the deer seemed to know better what to do about this than did its human friend. The fawn pulled the bandage off, carefully licked the hair away from the injured area and then exposed it fully to the fresh air and sunlight. What happened? In a short…
