The kidneys are the urine-forming organs of the body; they allow the body to remove toxins. Osmolarity in the loop of Henley s crucial for this function and is adaptive feature of mammalian and avian nephrons‚ which allow the kidneys to reabsorb more water through osmosis. The loop of Henley absorbs around 15% of the body’s filtered water is reabsorbed here dips into the medullar where there is a high concentration of NaCl‚ this creates a large vertical

Management of Fluid overload in Chronic Renal Failure (CRF) Chronic Renal Failure is a long term serious irreversible condition‚ described as the gradual loss of kidney function (McCarthy‚ et al 2009). The number of patients suffering from CRF in United Kingdom (UK) is rising rapidly. Ferenbach and Wood (2005‚ p.16) state that in UK‚ about 6000 people are commencing dialysis treatment per year. Fluid overload is a frequently observed finding in renal failure patients. About one third of the patients

Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

SENSE- is the ability to perceive stimuli. SENSATION (PERCEPTION)- is the conscious awareness of stimuli received by sensory receptors. GENERAL SENSES- are those with receptors distributed over a large part of the body. SOMATIC SENSES- provides sensory information about the body and the environment. VISCERAL SENSES- are more specialized in structure and are localized to specific parts of the body such as pain and pressure. SPECIAL SENSES- are more specialized in structure such as smell

Homeostasis literally means “same state” and it refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed. The importance of this cannot be over-stressed‚ as it allows enzymes etc to be ‘fine-tuned’ to a particular set of conditions‚ and so to operate more efficiently. Much of the hormone system and autonomic nervous systems is dedicated to homeostasis‚ and their action is coordinated by the hypothalamus. In Module 2 we saw how

INTRODUCTION — In almost all cases‚ hyponatremia results from the intake (either oral or intravenous) and subsequent retention of water [1]. A water load will‚ in normal subjects‚ be rapidly excreted as the dilutional fall in plasma osmolality suppresses the release of antidiuretic hormone (ADH)‚ thereby allowing the excretion of a dilute urine. The maximum rate of water excretion on a regular diet is over 10 liters per day‚ thereby providing an enormous range of protection against the development
