excretory system includes the kidney and its functional unit‚ the nephron. The excretory activity of the kidney is modulated by specialized hormones that regulate the amount of absorption within the nephron. Kidneys 1 ). They are bean-shaped organs located on either side of the backbone at about the level of the stomach and liver. Blood enters the kidneys through renal arteries and leaves throughrenal veins. Tubes called ureters carry waste products from the kidneys to theurinary bladder for storage

What is Dehydration & What causes it? Water is essential to maintaining a state of good health. Considering the adult body is comprised of nearly 60% water‚ this explains why such organs as the brain‚ kidneys‚ and heart cannot function effectively when lacking enough water supplies. Excessive water loss in the body‚ or dehydration‚ then places the body in a position that can become not only uncomfortable but in severe cases life threatening. Upon gaining

Introduction: During this laboratory exercise will identify by the graph given which is isotonic‚ hypotonic‚ or hypertonic. The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs. The process of urine formation and adjustment of blood composition involves three

getting rid of waste (diffusion) and unwanted water from the blood. This process is naturally done by our kidneys. Some people‚ however‚ may have failed or damaged kidneys which cannot carry out the function properly‚ they may need dialysis. The human body relies on homeostasis to function properly‚ so the body constantly makes adjustments to keep balanced within its physiological limits. The kidneys in the urinary system are a major workhorse in keeping the body in balance. They regulate the ionic composition

briefly describe the kinds of homeostasis involved. In males and females‚ intracellular fluid has a greater proportion of total body water than does extracellular fluid. Give-and-take between the ICF and the ECF happens across plasma membranes by osmosis‚ diffusion‚ and carrier-mediated transport. The kinds of homeostasis involved are fluid Balance‚ electrolyte Balance‚ and Acid–Base Balance. Fluid balance is when the quantity of water we gain each day is equivalent to the amount we lose to the

Would you expect osmosis and diffusion to stop when substances are evenly distributed? Support your answer. If there is no concentration gradient (when the substances are evenly distributed) there will be NO osmosis or diffusion. There will be movement across the membrane‚ because the molecules are always moving. This movement will be in equlibrium. 5.) What type

The kidneys act as a filter to filter the waste products from the blood‚ the ureters are tubes that transport the main waste products (urine) from the kidneys to the bladder‚ where it is stored until it is excreted out of the body through the urethra.

The maintenance of normal volume and composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved. 2. Why does maintaining fluid balance in older people require a higher water intake than in a normal‚ healthy adult under age 40? 3. Why does potassium concentration rise in patients with acidosis

good faucet and rest assured it works. Essentially what you have here is a reverse osmosis water system. The way this works is it uses a high-pressure pump to increase the pressure on the salt side. The system uses this salt for purifying your water. Once the system forces the water through the purification process almost all the salt is left and you have purified water. Studies show that reverse osmosis is actually quite effective. It does a good job of removing dissolved salts‚ Lead‚ Mercury

Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline Water Ionizers While water ionizers are arguably the most popular source of ionized water‚ such water can be produced with the aid of a water distiller. A distiller will convert regular water into steam‚ condense it back into water
