Kidney

Renal physiology (Latin rēnēs, "kidneys") is the study of the physiology of the kidney.
Renal physiology is the study of kidney function.

Reabsorption

reabsorbedtubular reabsorptionreabsorb
The major functions of these lining cells are the reabsorption of water and small molecules from the filtrate into the blood, and the secretion of wastes from the blood into the urine.
In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood.

Nephron

renal tubulenephronsrenal tubules
Much of renal physiology is studied at the level of the nephron, the smallest functional unit of the kidney.
These components function as the filtration unit and make up the renal corpuscle.

Ultrafiltration (renal)

ultrafiltrationglomerular filtratefiltered
Cells, proteins, and other large molecules are filtered out of the glomerulus by a process of ultrafiltration, leaving an ultrafiltrate that resembles plasma (except that the ultrafiltrate has negligible plasma proteins) to enter Bowman's space.
In renal physiology, ultrafiltration occurs at the barrier between the blood and the filtrate in the glomerular capsule (Bowman's capsule) in the kidneys.

Vasopressin

antidiuretic hormoneADHarginine vasopressin
The kidney is directed to excrete or retain sodium via the action of aldosterone, antidiuretic hormone (ADH, or vasopressin), atrial natriuretic peptide (ANP), and other hormones.
It then travels down the axon of that cell, which terminates in the posterior pituitary, and is released from vesicles into the circulation in response to extracellular fluid hypertonicity (hyperosmolality).

Renal glucose reabsorption

glucose reabsorptionGlucosereabsorption of glucose in the kidney
Renal glucose reabsorption is the part of kidney (renal) physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine.

Renal urea handling

cycling of and excretion of urea by the kidneysUrea
Renal urea handling is the part of renal physiology that deals with the reabsorption and secretion of urea.

Renal oligopeptide reabsorption

Oligopeptides
Renal oligopeptide reabsorption is the part of renal physiology that deals with the retrieval of filtered oligopeptides, preventing them from disappearing from the body through the urine.

Renal protein reabsorption

proteins
Renal protein reabsorption is the part of renal physiology that deals with the retrieval of filtered proteins, preventing them from disappearing from the body through the urine.

Bowman's capsule

Bowman capsuleBowman's spaceParietal epithelial cell
This is performed at the microscopic level by many hundreds of thousands of filtration units called renal corpuscles, each of which is composed of a glomerulus and a Bowman's capsule.
Measuring the glomerular filtration rate (GFR) is a diagnostic test of kidney function.

Renal sodium reabsorption

Renal reabsorption of sodium (Na + ) is a part of renal physiology.

Excretion

excretedexcretoryexcrete
Although the strictest sense of the word excretion with respect to the urinary system is urination itself, renal clearance is also conventionally called excretion (for example, in the set term fractional excretion of sodium).
The liver and kidneys clear many substances from the blood (for example, in renal excretion), and the cleared substances are then excreted from the body in the urine and feces.

Renal chloride reabsorption

Chloridecontrolled by the kidneys
Renal reabsorption of chloride (Cl − ) is a part of renal physiology, in order not to lose too much chloride in the urine.

Titratable acid

titratable acidity
See also titratable acid.
For example, in renal physiology, Titratable acid is a term to describe acids such as phosphoric acid, sulfuric acid which are involved in renal physiology.

Paracellular transport

The distinction has particular significance in renal physiology and intestinal physiology.

Renal function

glomerular filtration ratekidney functioncreatinine clearance
A global assessment of renal function is often ascertained by estimating the rate of filtration, called the glomerular filtration rate (GFR).
Renal function is an indication of the kidney's condition and its role in renal physiology.

Renal blood flow

renal plasma flowblood flow to the kidneykidney blood flow
In the physiology of the kidney, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time.

Carboxylate transporter

They are responsible for the reabsorption of filtered carboxylate in renal physiology, resulting in a 100% reabsorption in the proximal tubule.

Free water clearance

free water
In the physiology of the kidney, free water clearance (C H 2 O ) is the volume of blood plasma that is cleared of solute-free water per unit time.

Net acid excretion

In renal physiology, net acid excretion (NAE) is the net amount of acid excreted in the urine per unit time.

PAH clearance

Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function.

Creatinine

serum creatininenormal kidney functioncreatinin
A simple means of estimating renal function is to measure pH, blood urea nitrogen, creatinine, and basic electrolytes (including sodium, potassium, chloride, and bicarbonate).
Creatinine is removed from the blood chiefly by the kidneys, primarily by glomerular filtration, but also by proximal tubular secretion.
