Through a series of intricate pathways, capillaries and tunnels, the vasa recta help the kidney produce concentrated urine. The vasa recta contain a group of capillaries and vessels located in the kidneys. Biologically, the vasa recta lay parallel to the loop of Henle, which facilitates the flow of blood into and out of the kidneys.
Each vasa recta in the kidneys has a small turn in the medulla that transports blood away at a slow rate. This regulation of blood is important for maintaining a countercurrent exchange between the vasa recta and the loop of Henle; these two components work together to process and filter blood to remove impurities before sending it elsewhere in the urinary system and throughout the body. The ability of the vasa recta to regulate blood is critical. This task is what triggers the kidneys to produce and excrete concentrated urine. According to the North Carolina Wesleyan College, the vasa recta, in addition to having a series of short and straight capillaries, contain a long, descending tube on the downward side. In this tunnel, calcium and urea are cleansed and reabsorbed into the bloodstream. In the process, water is produced and secreted from the walls of the vasa recta. That water, like blood, is cleansed and exported throughout the body.Learn More
Having a high protein count in urine can be the result of kidney disease or other chronic medical condition, or it may be something temporary, states American Kidney Fund. Healthy kidneys should not allow an excessive amount of protein into urine, according to WebMD.Full Answer >
Dark brown urine can be caused by eating too much aloe or rhubarb or too many fava beans, according to the Mayo Clinic. It can also be caused by medications and certain diseases of the kidneys or liver. Urinary tract infections can also turn the urine dark brown.Full Answer >
Antidiuretic hormone, typically called ADH, reduces the amount of urine production and can also release water from the kidneys back into the circulatory system. Osmoreceptors, a type of sensory neuron, measure the concentration of certain chemicals in a human's bloodstream, and if the concentrations are too high, ADH is released. ADH then connects to and opens kidney cell receptors to allow water to dilute the blood.Full Answer >
The cerebellar vermis plays a role in maintaining equilibrium and coordinating speech, eye and body movement, specifically along the extremities. In addition, the vermis, together with the fastigial nucleus and flocculonodular lobe, are said to be involved in emotional processes.Full Answer >
