Glomerular Filtration Activity 1: Effect of Arteriole Diameter on Glomerular Filtration 1. Compare this data with your baseline data. How did increasing the afferent arteriole radius affect glomerular filtration rate? >>Increasing the afferent arteriole radius pushed the glomerular pressure‚ the glomerular filtration rate‚ and the volume of urine to be higher than the baseline data. Increasing the afferent arteriole radius increased the glomerular filtration rate. 2. Under

to an area of greater concentration (Campbell). To maintain the proper balance of salts and water in the aquatic environment fish‚ and all vertebrates‚ evolved to utilize a very specialized organ to solve this problem: The Glomerular/ Vertebrate Kidney (Washinton). In early evolving species‚ fish were beginning to live in freshwater systems after entire millennia of living in the oceans (Washington). This meant that their cells had a higher concentration of salts than the environment. According

osmolality constant. In humans the kidney plays a huge part in the osmoregulation of the body’s internal environment. Regulation of water in the human body is carried out through the excretion of waste urine from the body. Hormones which include: the antidiuretic hormone‚ aldosterone and angiotensin II are used in the body to help to increase the permeability of the collecting ducts found in the kidney. This further allows diffusing to occur easily‚ it also allows the kidney to be able to reabsorb water

There are countless tests that can be taken during a urinalysis that can help to show any abnormalities in the urine and rest of the body. The process of producing urine and removing toxins from the body occurs in the excretory system. The organs (kidneys‚ etc.) that are a part of this system are in charge of different aspects of urine production. When urine is being formed‚ there are three processes that must occur. The first step that occurs is filtration. In this step‚ diffusion occurs under high
