Information coming for "The Human Body In Health & Disease" textbook 6th edition

Jo is overhydrated (see case Study number 2). This chapter states that overhydration can place a dangerously heavy burden on the heart. Explain how overhydration can tax the heart.

What could put a person at risk to become overhydrated?  List at least 2 ways and briefly discuss how the body can return back to homeostasis safely, or what treatment is available to that specific person at risk.

Answer 1

Overhydration leads to reduce performance because our blood has to soak up some of the excess water in an attempt to equalize our body's salanity .Then our cells begin to sweel, causing all sorts of distess, from gastic to all other symptomps that do nothing to make us faster.

If we drink lot much of water than needed out circulatory system becomes diluted with excess water, the concentration of electrolytes in our blood drops relative to the concentration of electrolyte in our cells.

In effort to maintain an equal balance of electrolyte between our blood and our cells ,water will seep into the cells from blood ,causing cells to sweel up.

And ,if this sweeling occurs in brain .we will experience increased intacranial pressure i.e our brain will get squeezed because the flat bones that make up skull dont provide much give.

Dependind on how much water a person drank in a period of time a person can experience a wide vareiety of symptoms.

Since the brain is the organ most susceptible to overhydration ,a change in behaviour is usually the first symptom of water intoxication. The patient may become confused ,drowsy , or inactive.

           As, you may know homeostasis is the maintenance of a stable environment within an organism, and maintaing a stable internal environment in a human means having to carefully regulate many parameters including glucose level in blood.There are two major ways that signals are sent throughout the body.The first is through nerves of the nervous system.Signals are sent as nerve impulses that travel throgh nerve cell called neuron.

These impulses are sent to the neurons, or specific target cells at a specific location of the body that the neuron extends to.Most of the human body users to regulate body temperature are sent through the nervous system.

The second way that signals can be sent throughout the circulaory system. These signals are transmitted by specific molecules called hormones which are signaling molecules that travel through the circulatory system..
