Nephron

Kidneys- The kidneys function to filter both toxins and additional not needed water. Kidneys have tons of nephrons which are tiny filters. A nephron is made up of two parts which are the glomerulus and the tubule. The glomerulus filters large molecules and blood cells from liquids and toxins. Then the filtered liquids and toxins go to the tubules. The tubule filters out more toxins missed from the glomerulus. It also gathers minerals and releases them back into the bloodstream. During the…

intro The purpose of this essay is to identify what symptoms may occur in a person or animal which is suffering from renal failure? And what are the options for treatment in both humans and animals as well as determining which method of treatment fits best for the situation. To understand renal failure an understanding of the renal system is necessary, although renal failure is mainly associated with the kidneys. The renal system consisting of the kidneys, bladder and urethra is responsible for…

The process can take place in three parts. • Filtration – This process happens in the entire nephron system. When blood goes through and into the capillary at the beginning of the nephron, small molecules, such as glucose, urea, ions and water are cleaned out and passed through the nephron tubule. The larger molecules such as blood proteins, cannot fit through the capillary wall as they are too big, therefore they stay in the bloodstream. • Reabsorption – When the small molecules are cleaned…

Experimentation: Background The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, behind the stomach, one on each side of the spine. Each kidney contains s system of tiny filters called nephron. A…

In a strictly operational sense, calcium balance is determined by the relationship between calcium intake and calcium absorption and excretion. The system is that relatively small changes in calcium absorption and excretion that can neutralize a high intake or compensate for a low one. Moreover the calcium absorption is an ingested calcium mixes with digestive juice calcium in the proximal small intestine from where it is absorbed by a process, which has an active saturable component and a…

Review of Case Study The case study we chose to research relates to kidney disease, the increased incidence of caries and periodontal disease. This case study patient is a 49 year old Caucasian female. She is healthy with the exception of having polycystic kidney disease. For this condition the patient does not take medications or receive any type of dialysis treatments. This patient has several missing teeth, large restorations on all posterior teeth, crowns and root canals. Currently she…

The hypothalamus in located in the brain. It is responsible for regulating body temperature, some metabolic processes and it is the main part that controls the autonomic nervous system. The hypothalamus is also in control of the production of many vital hormones that play a major role in maintaining the right standards for your body and chemical substances that help control different cells and organs. The hormones released from the hypothalamus control physiologic purposes, such as sleep, mood…

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…

Each nephron consists of small blood capillaries called glomerulus, and the renal tubule. Urea, and water forms urine as it passes through the nephrons and down the renal tubules of the kidney. The two ureters are narrow tubes that carries urine from the kidneys to the bladder, the bladder is an organ located in the lower abdomen…

excessive exertion, convulsions or anoxia of the muscle for several hours, large amounts of myoglobin are usually excreted.”(Huether & McCance, 2012, p. 1097) In acute renal failure myoglobin precipitates in the tubules obstructing the flow through the nephrons and causing injury. Damage to the myocyte causes an influx of sodium into the cell and cytosolic calcium accumulation due to direct injury to the cell. The high calcium concentration has a number of dangerous effects including the…
