Title : Measuring the rate of oxygen uptake. Objectives : 1. To demonstrate the uptake of oxygen in respiration. 2. To measure the rate at which an organism respires. 3. To learn how to set up the apparatus for respirometers. Introduction : Respirometer A respirometer is a device that been used to measure the rate of respiration of a living organism. This can be measured by calculating the rate of exchange of oxygen and carbon dioxide. A simple respirometer designed to measure oxygen

Fryns syndrome is a rare congenital disorder that affects the development of the body and is characterized by coarse facial features‚ diaphragmatic hernia‚ pulmonary hypoplasia‚ distal digital hypoplasia‚ and other various associated anomalies.. There is a 25 percent risk of recurrence and the prevalence of Fryns is 0.7: 10‚000 births in France [2]. It affects 1:15‚000 live births [3]. J. P. Fryns first described Fryns syndrome in 1979. It was first described with two still born female siblings

Callum Bourke Describe the long term effects of exercise on the Muskoskeletal system and energy systems. (P3) Describe the long term effects of exercise on the cardiovascular and respiratory systems. (P4) Cardiovascular System Cardiac Hypertrophy The heart increases in size and volume; this allows more blood to enter the heart allowing a greater amount of oxygenated blood to be pumped to the working muscles. To withstand the large amount of blood‚ the left ventricle becomes thicker

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

Muscles‚ Joints and Body Temperature? After exercise‚ you’ll find your body experiences immediate and more gradual effects. The minute you start training‚ you’ll notice more frequent muscle contraction‚ raised body temperature and pulse‚ and deeper breathing known as tidal volume. Longer-term effects occur as the body adapts to regular exercise‚ including your heart getting larger‚ bones becoming denser and the vital capacity of your breath deepening. Bones‚ Joints and Muscles Immediate effects
