environment there are bound to be problems. The land organisms need to have water within their body that is able to be accessed when needed. A solution terrestrial organisms have developed is the loop of Henle in the kidneys. This is part of the nephron which makes a U-shape and is used to conserve and reabsorb water. Another solution to the problem of water loss is being nocturnal‚ which gives less water loss because of less heat. A second problem is gas exchange. Because oxygen is required‚ organisms

am going to explain the kidneys in more detail. The physiological overview involves the kidneys processing blood by eliminating any excess mineral salts‚ urea and water as this provides homeostasis and it enables the body to work effectively. The nephron (which is part of the kidneys) for example‚ is in charge of the reabsorption of amino acids‚ glucose‚ some chloride and sodium. It is composed of the Bowman’s capsule which is connected to a coiled tubule‚ which then moves into a hairpin loop called

trigger active transport mechanisms to allow the passage of those chemicals across the membrane. Some major examples of osmosis • Absorption of water by plant roots. • Re-absorption of water by the proximal and distal convoluted tubules of the nephron. • Re-absorption of tissue fluid into the venule ends of the blood capillaries. • Absorption of water by the alimentary canal — stomach‚ small intestine and the colon. Osmoregulation Osmoregulation is keeping the concentration of cell cytoplasm

The first part of digestion would be as soon as you use your sense of smell‚ which triggers your salivary glands to secrete saliva. Once you take your first bite‚ your saliva increases even more. You then break down the food by chewing. Even more saliva

Excretory system DEFINITION The excretory system is a passive biological system that removes excess‚ unnecessary materials from an organism‚ so as to help maintain homeostasis within the organism and prevent damage to the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and gaseous wastes‚ as urine and as a component of sweat and exhalation. As most healthy functioning organs produce metabolic and other wastes‚ the entire organism depends on
