P5-explain the concept of homeostasis
P6- follows guidelines to interpret collected data for heart rate, breathing rate and temperature before and after a standard period of exercise Homeostasis
Conditions in the body have to be controlled with narrow limits. This is called homeostasis. These conditions include water content, ion content, body temperature and blood glucose concentration. The thermoregulatory centre is the part of the brain that monitors and controls body temperature. The pancreas meanwhile monitors and controls blood glucose concentration. It produces a hormone called insulin that reduces blood glucose levels.( Diabetes is a disease which can be caused by insufficient insulin.) For example: let’s say it’s cold. The brain lets out impulses to for us to shiver to warm ourselves up and let the veins enlarge, but if we are cold the veins become smaller to cool ourselves down while also letting off sweat and any excess water.

Exercise and Results
| Before Exercise| After Exercise |
Heart Rate per minute | 62| 124|
Breaths Per Minute| 11| 17|
Temperature Degrees C| 34.5| 37.2|

Heart Rate/ Pulse
The pulse can be taken on two pressure points. One on the neck this is called carotid artery, this sometimes quiet hard to find, so most people measure from the wrist, the Radial artery, with two fingers, as the thumb as a pulse but is uneven and can affect accuracy. A Adults range of pulse should be 60-80 bpm resting, children’s and babies pulse is much faster and rapid. With mine on the lower end of the scale, means I am quite fit. Peoples exceeding 80, should be careful of high blood pressure or lack of exercise leading to obesity. Smoking, unhealthy diet, stress and infection or fever can affect the heart rate, putting it in more strain. The average heart rate for 15-20 year olds is 122-163 bmp. Exercise causes the blood to pump faster, making our intake for oxygen more and temperature rise, which creates sweat. Mine is the lower...
