food groups are: 1. Bread‚ cereals and potatoes: ( carbohydrate‚ calcium and iron‚ B vitamins and dietary fibre) - Carbohydrate is needed to provide energy. Starchy carbohydrates are broken down and converted to glucose which is either stored as glycogen in the liver and muscles or is circulated in the bloodstream where it can enter cells and be used as energy. - Dietary fibre is not absorbed but passes through the gastrointestinal tract‚ helping to keep it healthy before being excreted. - Calcium

Increased muscular activity results in a decreased partial pressure of oxygen‚ an increased partial pressure of carbon dioxide‚ a reduced PH‚ and an increased temperature. Consequently as much as 73% of the oxygen picked up by haemoglobin in the lungs is released in skeletal muscles during periods of physical exercise. Utilisation When we inhale air‚ oxygen is transported to the lungs and can be utilised by the body to stay alive. Oxygen is used to produce ATP for energy “the principle energy

The Great Metabolic Race Organisms are constantly undergoing various chemical reactions and pathways that enable for them to maintain life. These pathways are part of metabolism‚ involving catabolism (break down of organic nutrients for extraction of useful) and anabolism (energy dependent conversion of small precursor molecules in complex molecules); some of which are energy coupled to provide energy efficiency. This intermediate coupling is due to the “energy currency” within the body‚ known as

INTROduction TO THE HUMAN BODY 1. Define anatomy and physiology While anatomy provides us with a static image of the body architecture‚ physiology reveals the body’s dynamic and animated workings. Physiology often focuses on events at the cellular or molecular level. A. Anatomy – studies the structure of the body parts and their relationship to one another. i. Developmental – concerns structural changes that in the body occur throughout the lifespan. Embryology studies the developmental changes
