What Role Do The Kidneys Play In Water Regulation?
The kidneys are not only responsible for the elimination of harmful toxins from the body, but they are also responsible for regulating the balance of chemicals in the body. The two main kidneys are located in the back of the abdomen, positioned in the middle of the back on either side of the spine. The kidneys are there to perform important functions in the body, including the following:.
How does the kidney regulate water?
The kidney is an organ that acts as a filtration unit. It has the ability to filter out waste products from the body, while leaving in the water needed to keep functioning. If one has kidney disease, the kidney will lose its ability to filter out waste products..
What organs plays a role in water balance regulation?
The principal organs involved in water balance are the kidneys, the skin, the lungs, and the hypothalamus. The kidneys are responsible for controlling the amount of water in the body. If the water content is too high, the kidneys produce urine, which is a waste product of water, salt, and other toxins..
What is the role of the kidney in maintaining homeostasis?
Homeostasis is the ability or tendency of an organism to keep the body systems in balance. The kidney filters blood, balances its electrolytes, produces hormones, stores vitamins and minerals, and is involved in making red blood cells. A deficiency in the kidney causes fluid accumulation in the tissues, low blood pressure, fatigue, nausea, vomiting, bloating, loss of appetite, shortness of breath, frequent urination, dry skin, mental confusion, low blood sugar, low blood potassium, low blood calcium, low blood phosphorus, decreased ability to exercise, weight gain, slow wound healing, rash, dry eyes, hair loss, itchy skin, acidosis, and even death..
What is the function of the kidneys and maintaining homeostasis in the body?
The major function of the kidneys is to filter out the waste products from the blood and remove them via urination. The kidneys also maintain the equilibrium of chemicals in the body. These include ions like potassium, sodium, chloride, and hydrogen phosphates, as well as proteins and enzymes. The kidneys are responsible for regulating these chemicals, as well as the concentration of water in the blood. If the concentration of any of these chemicals becomes too high, they are excreted from the body..
How do the kidneys regulate electrolytes?
The kidneys regulate electrolytes (minerals like sodium and potassium that remain dissolved in the blood when in the right amounts) through a network of structures called nephrons. Each nephron consists of a renal corpuscle that filters blood and then transports the filtered blood to a renal tubule that is part of a larger network of tubules called the nephron loop. At the end of the nephron loop is the renal capsule. So blood is filtered by a renal corpuscle and then travels to a renal capsule where it is processed and eventually expelled from the body through the ureter. If a nephron is blocked at any point in this system, electrolytes can become imbalanced..
How does the kidney maintain water and electrolyte balance?
The kidney maintains water and electrolyte balance by controlling the amount of water that is excreted in urine. The kidney does not excrete sodium (Na). It removes excess water and salt (NaCl) if the blood becomes too concentrated (hypertonic) or retains water and sodium (NaCl) if the blood becomes too dilute (hypotonic). When the composition of the blood plasma becomes too concentrated, the kidney produces an antidiuretic hormone (ADH) which increases the permeability of the collecting duct to water. When the composition of the blood plasma becomes too dilute, the kidney produces a hormone called arginine vasopressin (AVP) which causes the collecting duct to become more permeable to water, thus passing more water into the urine. Thus the kidney adjust the volume of urine according to changes in the plasma composition..
How does our body regulate water?
Our body’s water balance is maintained by a hormone called vasopressin or antidiuretic hormone (ADH). When our body has a lot of water, ADH intake is increased and a signal is sent to the kidney to return more water to circulation. When ADH is not present in the blood stream, the kidney creates a large amount of ADH and the blood vessels in the kidneys are constricted. This causes the kidneys to hold more water and it is returned to circulation..
