Stop Breathing… or Die The earth’s atmosphere is a constantly moving body of gases that encircle our planet. This body of gases known as air is a mixture‚ not a chemical combination‚ of a number of gases; that is‚ each gas retains its own characteristic properties. It consists of about 78 percent nitrogen; 21 percent oxygen‚ and carries along with it water vapor‚ clouds‚ dust‚ smoke‚ soot‚ and a variety of chemical compounds. The remaining one percent contains all the other gases including carbon

of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths in 10 seconds

This it the reason why the pulse rate and breathing rate rapidly increases during exercise. Pulse rate increases when the blood rapidly gets pumped by the ventricles‚ causing the arteries to expand. As well as it is an indication that extra food and oxygen are being transferred throughout the body. Breathing rates increase due to the fact that during exercise‚ the demand for oxygen increases to help support the muscles and

Science: Abstract: This investigation is to show the raspatory and circulatory systems in deeper meaning. It also explains the reasons for why breathing and heart rate becomes higher during physical activity‚ and if there are any differences between female and males. This experiment shows the biological principles‚ and how to record and produce data of a quality standard. Introduction: Air goes into the alveoli when we breathe in. This lets the veins around the alveoli drop of their carbon dioxide

on the ocean floor so important? The discovery of no rocks older that 2 billion years old on the ocean floor proved the theory of seafloor spreading. 9. How do scientists explain the formation of underwater mountain ranges? Scientists believe seafloor spreading explains the formation of underwater mountain ranges. 10. How do scientists use sound waves to figure out the shape of the ocean floor? Scientists use sound waves to figure out the shape of the ocean floor because sound waves echo off

"Explain the concept of homeostasis with reference to the control of heart rate‚ breathing rate‚ body temperature and blood glucose levels" P5 Homeostasis is where the body keeps a constant internal environment. This involves all the metabolic processes taking place In the body as well as the blood‚ tissue fluid and all the contents in the body ’s cells. There are a range of variables from heart rate to the blood glucose levels that the body will take into account. Negative feedback will occur
