What Is The Function Of Your Kidneys – As a rule, each of us is born with two kidneys. They are located in the back of the body on each side of the spine, embedded under the ribs. Each kidney is about 12 inches long, 3 inches wide (8 cm), and 2 inches wide (5 cm) and each weighs 10 to 12 ounces (280 to 340 grams).
Polycystic kidney disease (PKD) affects both kidneys. The number of cysts detected by imaging increases with age and can range from a few to too many to count. The size of individual cysts increases as they grow and can range from the size of a pin to the size of a grapefruit.

What Is The Function Of Your Kidneys
On average, a PKD patient’s total kidney function (TKV) measured by MRI will increase about five percent per year even though your kidney function remains within normal limits for decades. Studies have shown that expansion of TKV to 1, 000 to 1, 500 mL (normal TKV: 250-350 mL) is associated with a greater risk for future kidney failure. Therefore, TKV is used as a surrogate marker of disease in clinical trials of new drug treatments for PKD.

Each of your kidneys contains about a million tiny filters called nephrons. Nephrons are made of thin blood vessels in a circular shape called a glomerulus which is connected to a series of tubules. Almost a quarter of your heart’s blood flow every second passes through the nephrons. Red blood cells, white blood cells, and large particles such as proteins do not normally pass through, staying in the glomerular blood vessels instead. The 180 liters (about 47 gallons) of water that pass through your kidney’s filters each day are water, electrolytes (sodium, potassium, calcium, and phosphorus) and other trace elements. Most of the water that passes through the glomerulus is changed and recycled when it passes through the tubules of the nephron. This leaves about two liters (a quart to a half gallon) of urine per day. The process of filtering and reabsorbing water around the nephron helps the normal kidney to manage electrolytes and regulate the blood pH within a certain concentration or range. Your kidneys also filter and remove waste products from your diet and your body’s metabolism every day.
Blood Urea Nitrogen (BUN) and creatinine are two waste products that are removed by the kidneys. In particular, creatinine is removed so well that kidney function can be estimated from the level of this substance in the blood. Your doctor can calculate how much kidney function you actually have using a blood test for creatinine. This can be used to calculate your estimated glomerular filtration rate (eGFR). Your EGFR tells your doctor what percentage of “normal” kidney function you have.
Your kidneys also make many important hormones and enzymes. One of these is renin, an enzyme that stimulates the production of other hormones such as angiotensin (helps control blood pressure) and aldosterone (helps manage salt and potassium). Another hormone made in the kidneys is erythropoietin, commonly called EPO. This hormone tells the bone marrow to make red blood cells. If your kidneys are removed during surgery or if they fail due to kidney disease, EPO is no longer produced, and you may bleed. A synthetic form of EPO is available that patients can take to correct their anemia. Kidneys also convert vitamin D into its active form, which helps the body absorb calcium from food. In this way, the kidneys help regulate the levels of calcium and phosphate in the blood and thus bone formation. Chronic kidney disease (CKD) is a gradual loss of kidney function, causing excess fluid, electrolytes, and waste products in your body. If you or a loved one has CKD, it is important to educate yourself so that you can:
Your kidneys filter excess water and waste from your blood, and remove them through your urine. Kidneys balance your body’s water, regulating blood chemistry (ie acid-base, sodium, phosphorus, potassium). regulate blood pressure, ensure bone health, and support overall heart and blood vessel function.
Kidney Function 101
Causes of chronic kidney disease include diabetes (the most common cause), high blood pressure, medications (NSAIDs, chemotherapy, contrast dyes), infections, poor heart disease, and frequent kidney injuries. , and autoimmune conditions.
Chronic kidney disease cannot be reversed and has a progressive decline (rate of change), which means it can get worse over time. Acute kidney injury develops suddenly and lasts a short time. It can be reversible or chronic.
Stage 5 CKD indicates that your kidneys are severely damaged and are functioning below 10-15%. People often feel depressed about their kidney disease at this stage, as their symptoms increase.
InterMed Consultants has been providing renowned kidney care in the Minneapolis area, and greater Minnesota, since 1979. Through new patient counseling and continuing education, we provide expert care for all your kidney needs. Kidneys lie in the retroperitoneal cavity behind the abdomen, and filter the blood to produce urine
Kidney Cleanse: Why You Should Speak To Your Doctor
They are located on the left and right sides of the retroperitoneal space, and adult humans are about 12 cm (4+ 1 ⁄2 inches) in length.
They receive blood from the paired ral arteries; blood drains into conjoined ral veins. Each kidney is connected to a ureter, a tube that carries urine out to the bladder.
Kidneys participate in the control of the volume of various fluids of the body, water osmolality, acid-base balance, various electrolyte concentrations, and elimination of toxins. Filtration occurs in the glomerulus: one-fifth of the blood volume that reaches the kidneys is filtered. Examples of reabsorbed substances are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of secreted substances are hydrogen, ammonium, potassium and uric acid. Nephron is the structural and functional part of the kidney. Each adult male kidney has about 1 million nephrons, while a rat kidney has only about 12,500 nephrons. Kidneys also function independently of nephrons. For example, they change what causes vitamin D and its active form, calcitriol; and synthesize the hormone erythropoietin and rin.
Chronic kidney disease (CKD) has been recognized as a leading public health problem worldwide. The global prevalence of CKD is 13.4%, and patients with kidney failure requiring renal replacement therapy are estimated to be between 5 and 7 million.
Chronic Kidney Disease (ckd)
Methods used to manage kidney disease include chemical and microscopic analysis of urine (urinalysis), measuring kidney function by calculating the estimated glomerular filtration rate (eGFR) using serum creatinine; and a kidney biopsy and CT scan to check for abnormalities. Kidney failure is treated with dialysis and kidney transplantation; One (or two in a row) of these is almost always used where the ral function drops below 15%. Renal cell carcinoma is often treated with nephrectomy.
Renal physiology is the study of kidney function. Nephrology is a medical specialty that deals with diseases of kidney function: these include CKD, nephritic and nephrotic syndromes, acute kidney injury, and pyelonephritis. Urology deals with kidney (and urinary tract) anatomy: these include cancer, ral cysts, kidney and urethral stones, and urinary tract obstruction.
The word “ral” is a word meaning “related to the kidney”, and its root is Frch or late Latin. While according to some opinions, “ral” should be replaced with “kidney” in scitific texts like “artery”, other experts support to preserve the use of “ral” as a proper term included in “ral artery”.

About Your Kidneys
In humans, the kidneys are high in the abdominal cavity, one on each side of the spine, and lie in a retroperitoneal position in the lower abdomen.
Abdominal asymmetry, caused by the condition of the liver, often results in the right kidney being slightly lower and smaller than the left, and placed slightly more centrally than the left kidney.
And the right hand is slightly lower. The right kidney sits below the diaphragm and behind the liver. The left kidney sits below the diaphragm and behind the spleen. Above each kidney is an adrenal gland. The upper part of the kidney is protected by the eleventh and twelfth ribs. Each kidney, along with its adrenal gland, is surrounded by two layers of fat: the periral fat between the ral fascia and the ral capsule and the pararal fat above the ral fascia.
The recess in the concave border is the ral hilum, where the ral artery enters the kidney and the ral vein and ureter exit. The kidney is surrounded by tough fibrous tissue, the ral capsule, which is itself surrounded by periral fat, ral fascia, and pararal fat. The anterior (front) surface of these tissues is the peritoneum, while the posterior (posterior) surface is the transversalis fascia.
Tips To Keep Your Kidneys Healthy
The upper lobe of the right kidney is adjacent to the liver. For the left kidney, it is next to the spleen. So they both come down to breathing.
