claimDialysis is a medical procedure that uses a machine to perform some of the physiological functions of the kidneys for patients experiencing total kidney failure.
claimA human can live a normal life with only one functioning kidney.
measurementApproximately 20 percent of all plasma flowing into the kidneys leaves the capillaries and is collected in the capsules surrounding them.
claimThe kidneys function to clean the blood and maintain the body's fluid volume.
claimRenal failure can be caused by a malfunction of the cardiovascular system, such as the clogging of capillaries, which prevents the kidneys from performing their function.
claimThe brain regulates blood pressure by monitoring sensors in the body and signaling the cardiovascular system to slow the heart and open blood vessels, and signaling the kidneys to excrete fluid when pressure is too high.
claimAntidiuretic hormone (ADH) decreases the amount of water excreted by the kidneys to prevent dehydration and can increase blood pressure.
claimThe adrenal glands are small glands located near the kidneys that produce several hormones.
claimThe kidneys are the primary organs of the renal system and function to regulate the amount and composition of body fluids.
claimAldosterone, the major mineralocorticoid, modifies the kidneys' excretion of sodium, potassium, and hydrogen.
claimThe kidneys regulate plasma volume and composition by filtering plasma and returning appropriate amounts of fluid and substances back to the blood.
7 Major Organ Systems: Functions and Connections instituteofhumananatomy.com Nov 23, 2025 8 facts
claimEach human kidney contains approximately one million nephrons, which serve as the primary filtration units for removing waste, toxins, and excess substances from the blood.
claimAntidiuretic hormone (ADH) assists the kidneys in conserving water during states of dehydration.
claimThe kidneys maintain blood pH by balancing hydrogen and bicarbonate ions.
claimThe kidneys produce the hormone renin to help control blood pressure and the hormone erythropoietin to stimulate red blood cell production.
claimThe kidneys regulate blood volume and pressure by controlling the amount of water the body reabsorbs.
claimThe adrenal glands sit on top of each kidney and handle stress responses by producing cortisol and adrenaline to prepare the body for fight-or-flight situations.
claimThe adrenal glands are small, triangular structures located on top of each kidney, consisting of a yellowish outer cortex and a darker inner medulla.
claimThe kidneys interact with the circulatory system by filtering the blood supplied by the circulatory system and producing hormones that influence both the circulatory and endocrine systems.

claimNephrons within the kidneys filter blood passing through the glomerulus (a web of capillaries), which then passes through tubules and collecting ducts to form urine.
claimThe kidneys are paired, bean-shaped organs placed retroperitoneally that receive a rich blood supply via the renal artery.
claimThe urinary system is a body drainage system comprised of organs that produce and excrete urine, specifically the kidneys, ureters, urinary bladder, and urethra.
claimBlood filtrate passes through a series of tubules and collecting ducts within the kidneys to form urine.
claimUreters are tubes of smooth muscle that convey urine from the kidneys to the urinary bladder.
claimNephrons within the kidneys filter blood that passes through their web of capillaries, known as the glomerulus.
claimUrine is conveyed from the kidneys to the urinary bladder via the ureters, which are tubes of smooth muscle.

claimVital organs are defined as organs that are necessary for human survival, including the brain, heart, kidney, lungs, and liver.
claimHumans can survive with only one of several paired organs, such as the lungs or kidneys.
claimPaired organs in the human body, which have one on each side, include the lungs, kidneys, eyes, ears, and reproductive organs such as testicles and ovaries.
claimThe brain, heart, kidney, lungs, and liver are examples of vital organs.
referenceThe urinary system includes internal organs such as the kidneys and bladder, and external genitals such as the penis.
Life, Intelligence, and Consciousness: A Functional Perspective longnow.org Aug 27, 2025 2 facts
claimBiological functions, such as the kidney's role in filtering urea, are computable functions in the mathematical sense defined by Alan Turing, which implies that these functions are multiply realizable.
claimCochlear implants can be considered to be reproducing in the context of the 'technosphere' because their numbers increase over time, similar to how a kidney cannot reproduce in isolation but requires a larger living system.

Is There a Male Brain and a Female Brain? | Child & Family Blog childandfamilyblog.com 2 facts
claimResearch indicates that there are far more similarities between female and male brains than there are differences, and brains are more comparable to organs like the heart and kidney than to reproductive organs.
measurementWhile the average size of women's and men's brains differs by 11%, the size of other human organs differs by larger percentages: hearts by 17%, lungs by 23%, livers by 14%, pancreases by 18%, kidneys by 19%, and thyroids by 25%, with all these organs being larger in men.
