excretion of waste‚ and the production of hormones. Although the kidney performs all these functions‚ the renal disease Glomerulonephritis‚ also known as glomerular nephritis and abbreviated GN relates to the excretion of waste. With this disease‚ the part of your kidney which is called the renal corpuscle is damaged. The renal corpuscle consists of glomerular capillary endothelium‚ a basal lamina‚ and the epithelium of Bowman’s capsule. Kidney function can be lost within weeks or months with this disease

Question #5 Unlike their friend Jemima‚ the other patients have all experienced a drop in blood pressure (Hypotension) and have an elevated heart rate (125-135 bpm) Hypertension occurs when blood pressure drops below 90 mm Hg systolic or 60 mm Hg diastolic number. Due to the girls all consuming substances that affect their bodies to normally retain water‚ they have all suffered similar symptoms but to different degrees. Dehydration causes the volume of blood circulating through the body to decrease

Which solute(s) were able to pass through the 20 MWCO membrane? None of the solutes were able to pass through the 20 MWCO membrane. A possible reason to why none of the of these solutes were able to pass through was because the solutes could have been too big to be transported. According to your results

glomerulus is the different membrane areas within‚ each are important to glomerular filtration. The epithelial layer made of podocyte cells lines the Bowman capsule that form slit pores to prevent red blood cells and proteins from entering the filtrate‚ and the mesangium layer which help regulate the amount of blood flow through the glomerulus with a muscle like contractibility (Grossman & Mattson-Porth‚ p. 1002). Glomerular disease affects the function of the kidney. Depending on source‚ it may

student who participated in strenuous activities on a hot day without planning for proper hydration. In pronounced dehydration‚ hypotension can occur. How would this affect the glomerular filtration rate of the kidney? What actions by the juxtaglomerular apparatus would occur to restore GFR? The glomerular filtration rate would decrease with a decline in blood pressure. The juxtaglomerular apparatus participates in renal autoregulation and‚ when activated‚ increases GFR. The process involves the
