Task 3
Unit 5

Liz Bamber

Our bodies are constantly changing with the environment and the weather, the internal environment of our body must be kept the same for the internal process’s to take place regardless of the outside environment.

Homeo stands for ‘same’ and statis stands for ‘level’ so Homeostatis is where things are kept on the same level. Conditions within the body must be carefully controlled at all times to allow our bodies to function normally, this is called Homeostatis, it’s   responsible for sending and receiving messages though the nervous system, interpreting and responding appropriately to the body's demands.

These conditions include water content, ion content, heart rate, breathing rate, body temperature and blood glucose concentration. The thermoregulatory centre is the part of the brain that monitors and controls body temperature, It gathers information as nerve impulses from temperature receptors in

the brain, these are sensitive to the temperature of the blood flowing there and the skin - these are sensitive to skin temperature

The pancreas meanwhile monitors and controls blood glucose concentration. Negative feedback is a regulatory mechanism which is used to control it all. Negative systems require, receptors to detect change( although this isnt so good in elderly and children because receptors either arent yet produced or die, so therefore if the elderly or children suffer from a temperature change it can be a lot more dangerous and potentially lead to death), a control centre to receive the information and process the response, effectors to reverse the change and get back to the original ‘normal’ state.

Homeostatis mechanism for regulation of body temperature

The normal core body temperature of human beings is 37 degrees if this drops of increases sufficiently then homeostatis will take place and return it back to normal using negative feedback. The skin plays a massive role in homeostatis for the regulation of...
