    the food we eat (mainly from carbohydrates and fats) a process called respiration. Respiration is the chemical process whereby energy is obtained from the body of a living organism with or without the use of oxygen. Energy is also essential in the body to enable breathing and take in oxygen. Carbohydrates are broken down into glucose which is soluble in blood (can dissolve in blood). Energy is also needed in the body to circulate blood and tissue fluid throughout the

    measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There is a direct relationship between oxygen consumption and Carbon

    photosynthetic organisms. If the world never had these organisms the world would be a desolate place. There would be no oxygen‚ atmosphere‚ or food. We inhale air unconsciously every day. By taking in air‚ we absorb oxygen and discharge carbon dioxide in the process of generating energy. It is a physiological phenomenon‚ called respiration. Most organisms on earth breathe. Then‚ how is oxygen generated and where does carbon dioxide go? The answer to this is plants. When we breath out carbon dioxide the

    and terrestrial environment. The Order Anura shows the extreme anatomical and physiological diversity. Many frogs use lungs to respire‚ bringing in air through their nares‚ mouth‚ into the trachea and then to the lungs for gas exchange and uptake of oxygen. The skin of many frogs is thin and extremely vascular to allow for gas exchange and thus can live in moist environments and secrete mucous from their skin to avoid desiccation. Cutaneous respiration

    the body deals with an increased workload‚ and any health issues that may affect this. Cardiovascular system This system is responsible for pumping blood and oxygen around the body. It is a network made up of blood vessels that transport carbon dioxide from the body to the lungs. The heart is an organ so needs a constant supply of oxygen. This is supplied by a separate network of blood vessels called the coronary system‚ made up of coronary veins and arteries. The heart is the size of a clenched
