protein because in the lab manual it says that a trace amount of albumin in Max’s urine is normal. 3. If ADH levels increase‚ water reabsorption by the DCT/collecting ducts increases and the resulting urine excreted is concentrated. 4. Max’s ADH levels are the highest immediately after exercise. The reason for this is because the color of his urine is dark yellow. According to the lab manual‚ concentrated urine can be observed with a darker

This project is based on ‘The Excretory System’. It has vital information such: What it is‚ the functions‚ what makes it up‚ the importance of the system in physical activity and what happens if the system does not work. It contains diagrams‚ pictures and even interesting facts. Enjoy! Acknowlegement We would like to thank the Lord for providing us with the ability to put together this project. We would like to our parents for helping us to gather and put all this information together
Premium Kidney Urine Urinary bladder
The kidney is made up of nephrons‚ which are a kidney’s functional units. These nephrons collect fluid filtered from the blood. The kidney connects to the renal artery‚ renal‚ vein‚ and ureter. Purified blood leaves the kidney using the renal vein‚ urine leaves using a ureter and the renal artery carries blood from the aorta to the kidney. The nephron has a cup-shaped nephric capsule that surrounds a cluster of capillaries called the glomerulus. A good deal of fluid from the blood filters into the

Measure the potassium iodide. Weigh out approximately 2 g of solid KI. This amount is a large excess over that which is needed. 3. Oxidize the iodide ion with hypochlorite ion. Using a graduated cylinder‚ transfer 25 mL of the dilute bleach into an Erlenmeyer flask. Add the KI and about 25 mL of distilled water. Swirl to dissolve the KI. Working in a fume hood and slowly with swirling‚ add approximately 2 mL of 3 M HCl. The solution should be a dark yellow to redbrown from

describes how much of a particular substance there is in a specific volume of solution. □ A dilute solution has only a little of the substance in a lot of water. □ A concentrated solution has a lot of the substance in less water. If we take 100cm3 beakers of dilute acid and concentrated acid‚ there will be fewer acid particles in the beaker of dilute acid than in the beaker with concentrated acid‚ even though the volumes of the two solutions are the same. In chemistry‚ we count particles

As the pressure increased‚ the urine volume increased proportionally. 3. Increased blood pressure can be a result of increased blood volume. For this reason‚ an increase in urine volume would stabilize blood volume. 4. If you close the one way valve‚ pressure will increase in the Bowman’s capsule and filtration rate will decrease. 5. With increased pressure and the valve closed‚ the filtration rate decreased but the glomerular pressure stayed the same. Urine output was zero. Activity 3: 1

Erik Lipka Mrs. Van Mierlo English 101 05 21 February 2013 The Effects of Dehydration and Hydration Water is a necessity in our world today but especially involving the health of human beings. Water is so important to human life that we would not survive without it because people become dehydrated when an insufficient supply of fluids are consumed in a day. “Human survival is dependent on water -- water has been ranked by experts as second only to oxygen as essential for life” (“Health Benefits
