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
The urethral meatus is the opening through which vertebrates pass urine and semen. In males, the urethral meatus is located at the tip of the penis, while in females the urethral meatus is located in the folds of the labia. Occasionally, the urethral meatus can become damaged, injured or swollen, causing problems for the animal.Full Answer >
A normal human bladder can hold 1.5 to 2 cups of urine, which is the equivalent of 12 to 16 ounces. The kidneys produce 1 to 2 quarts of urine daily by filtering 120 to 150 quarts of blood.Full Answer >
In anatomy, the loop of Henle is a long portion of a minute tube that moves urine within an animal's kidneys. This structure is found in a number of different animals, including reptiles, birds and mammals. It recovers certain chemicals from the urine of these animals and produces a much more concentrated form of urine, preserving water. Loops of Henle are especially important for animals that live in dry climates.Full Answer >
Blood in the urine, also known as hematuria, occurs in 2.5 to 21 percent of individuals and is usually not a significant cause of alarm, according to the Urology Care Foundation. However, blood in the urine can also be a symptom of cancers, diseases, infections, injuries and urinary stones.Full Answer >
