Glomerulus

large plasma solutes. For example, albumin is filtered out at this point, with only a tiny amount remaining in the subsequent glomerular filtrate. Because the afferent arteriole to the glomerulus is much larger than its efferent arteriole, fluid gets slowed down here quite a bit. The fluid that escapes the glomerulus through the efferent arteriole eventually goes to the renal vein. The rest of the glomerular filtrate is absorbed by the glomerular capsule directly adjacent to the…

. The urinary system is home of: two kidneys, two ureters, the bladder, the sphincter muscle, the nerves in the bladder and the urethra. The kidneys remove urea from the blood through, nephrons. Each nephron entails of glomerulus, and a renal tubule. The glomerulus is what filters the blood, the watery solution. Urea, together with water and other waste matters makes the urine then it passes through the nephrons and down the renal tubes of the kidneys. The ureters are narrow tubes that…

urine, with reference to the processes of ultrafiltration and selective reabsorption Ultrafiltration 1. Blood flows into the glomerulus from the afferent arteriole which is wider than the efferent arteriole which carries the blood away from the glomerulus. 2. This means that the blood in the capillaries is under increased pressure. 3. The blood pressure in the glomerulus is higher than in the Bowman’s capsule. 4. So fluid from the blood is pushed in the Bowman’s capsule. 5. Molecules with…

History of Organ Transplants The first organ transplants took place in 200 BC. A Chinese physician, Hua-Tuo, is said to have replaced diseased organs with healthy ones. He is also the first physician to use anaesthesia. Both of these are significant. Organs could be replaced and anaesthetics were available. Not much is recorded about organ transplants until the late 17th and early 18th centuries, when experiments with animal to human blood transfusions, skin grafts, and animal to human…

Urinary system Objective: to distinguish key microscopic components of the renal cortex and the Meduna. Also identify the structural components of the nephron. Describing the structures of the surface across which, filtration occurs. Also, identifying the proximal tubule, distal tubule and connecting duct. Name and identify the ureter, bladder and urethra Introduction: The urinary system consists of two kidneys. The urinary system performs many functions removing waste, products from the…

Acute renal failure is the sudden dysfunction or disease of the kidneys that can significantly impair renal function within the body. According to Huether and McCance (2012), renal failure is characterized by enough of a decline of renal function to require dialysis. Renal failure is after renal risk and injury, but prior to renal loss and end-stage kidney disease (Huether & McCance, 2012, p755). The dysfunctions the lead to acute kidney failure can be caused due to sudden renal injuries or by…

The kidneys are a pair of bean shaped organs that sit to each side of the vertebral column, with the left kidney situated slightly lower than the right. Remarkably, the pair of organs are able to process in the region of 1700 L of blood a day whilst only weighing approximately 113 – 170g (Porth, 2005). The blood is supplied to each kidney via a renal artery branching off from either side of the aorta (Martini, 2006), the renal artery then divides into segmental arteries that sub-divide into…

out from the kidneys and they are often referred to as water tablets. It works by eliminating water and salt from the body through urination. In the kidneys, salt and water are filtered out of the blood and into the tubules of the kidney to the Glomerulus (Waugh and Grant, 2014), making the filtered fluid into urine (Omudhome, 2014). The sodium, chloride and water that are filtered out of the blood is then reabsorbed back into the blood before being eliminated as urine (Omudhome, 2014).…

membrane decreases, thus decreasing the overall glomerular filtration rate (GFR) of the kidney and leading to complications associated with low GFR. Glomerulonephritis can be caused by primary or secondary glomerular injuries. Primary injury to the glomerulus include damage from immunologic responses, ischemia, free radicals, drugs, toxins, vascular disorders (BOOK REF). Secondary injuries to…

The body is the most important thing to humans than anything else. It is important to take care of the body from any harm. One thing that the body is capable of is maintaining pH levels and buffers. A pH is the power of hydrogen and buffers prevent extreme shifts in pH. The blood has a specific type of buffer that is maintained at pH level of 7.4. If the buffers shifts and levels of pH go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate…
