Peritubular capillaries. In the renal system, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron. Peritubular capillaries surround the cortical parts of the proximal and distal tubules, while the ...
As with glucose, the transfer is at the proximal tubule, but in the opposite direction: from the peritubular capillaries to the lumen. At low levels, all the PAH is transferred, but at high levels, the transport maximum is reached, and the PAH takes longer to clear. In practice, the transport maximum is not all-or-nothing.
15624. Anatomical terminology. [edit on Wikidata] The glomerulus (pl.: glomeruli) is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons. The tuft is structurally supported by the mesangium (the space between the blood ...
The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. At this location, the glomerular parietal epithelial cells (PECs) lining bowman’s capsule abruptly transition to proximal tubule epithelial cells (PTECs). The proximal tubule can be further ...
Metanephrogenic blastema. Identifiers. Latin. tubulus contortus distalis. FMA. 17721. Anatomical terminology. [edit on Wikidata] The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting tubule.
By convention, outward force is defined as positive, and inward force is defined as negative. The solution to the equation is known as the net filtration or net fluid movement (J v). If positive, fluid will tend to leave the capillary (filtration). If negative, fluid will tend to enter the capillary (absorption). This equation has a number of ...
The renal medulla (Latin: medulla renis 'marrow of the kidney') is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to form the segmental arteries which then branch to form interlobar arteries.
Podocyte. Renal corpuscle structure Blood flows in the afferent arteriole at the top, and out the efferent arteriole at the bottom. Blood flows through the capillaries of the glomerulus, where it is filtered by pressure. The podocytes (green) are wrapped around the capillaries. Blood is filtered through the slit diaphragm (or filtration slit ...
