Respiration

1. Respiration By Poppy Mumford and Immy Reynolds

2. Equation for respiration. • Glucose + Oxygen = Carbon Dioxide + Water + Energy • C6H12O6+6O2=6CO2+6H2O+Energy

3. Equation for photosynthesis. • Carbon dioxide+ Water+ Energy= Oxygen+ Glucose

5. How the Respiratory system works. • The respiratorysystem's function is to allow oxygen exchange through all parts of the body. The space between the alveoli and the capillaries, the anatomy or structure of the exchange system, and the precise physiological uses of the exchanged gases vary depending on organism. In humans and other mammals, for example, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs. • Other animals, such as insects, have respiratory systems with very simple anatomical features, and in amphibians even the skin plays a vital role in gas exchange. Plants also have respiratory systems but the directionality of gas exchange can be opposite to that in animals. The respiratory system in plants also includes anatomical features such as holes on the undersides of leaves known as stomata.

6. 14 interesting facts • Male lungs average 1060 grams, while female lungs average 930 grams. • They are the largest organ in the body and each lung is composed of smooth, shiny lobes. • An estimate Our lungs are about the size of a pair of footballs. • The surface area of the lungs is roughly the same size as a tennis court. • Male lungs weigh on average 1060 grams, while female lungs average 930 grams. • Each day an average person breathes about 25,000 times, and by the time a person reaches 70 years old, they will have taken at least 600 million breaths. • The lungs are the only organ in the body that can float on water. • In the course of a single day, 8,000 to 9,000 litres of breathed-in air meets 8,000 to 10,000 litres of blood pumped in by the heart through the pulmonary artery. • The lungs are the largest organ in the body and the only internal organ exposed to the external environment. • With each breath, a host of alien substances enter our bodies – including pollens, dust, viruses, bacteria and the constituents of the air in our homes and offices and factories, ranging from animal dander and tobacco smoke to radon and airborne lead. • New babies at rest breathe between 40 and 50 times per minute. By age five it decreases to around 25 times per minute. • At rest, an adult breathes about 14 to 16 times per minute. After exercise this can increase to over 60 times per minutes. • 90% of the lung is filled with air and only 10% is hard tissue.
