Vasa14
- The vasa recta of the kidney, (vasa recta renis) are the straight arterioles, and the straight venules of the kidney, - a series of blood vessels in the blood supply of the kidney that enter the medulla as the straight arterioles, and leave the medulla to ascend to the cortex as the straight venules. (wikipedia.org)
- Whereas the peritubular capillaries surround the cortical parts of the tubules, the vasa recta go into the medulla and are closer to the loop of Henle, and leave to ascend to the cortex. (wikipedia.org)
- RBC sickling and congestion in the vasa recta leads to ischemia and associated impairment of solute reabsorption by the ascending limb of the loop of Henle and impairs urinary concentrating ability. (medscape.com)
- The renal medulla contains the vasa recta-that is, the capillaries that are derived from the efferent arterioles of the juxtamedullary glomeruli. (medscape.com)
- The low oxygen tension or relatively hypoxic, hypertonic, and acidotic environment of the inner medulla predisposes RBCs in the vasa recta to sickle, particularly in the settings of severe intravascular volume depletion. (medscape.com)

(pharmacy180.com)

Diuretics1
- Atrial natriuretic peptide, a neuropeptide, is the predominant salt-excreting stimulus along with decreases in angiotensin II and sympathetic activity resulting in decreased sodium resorption, thus producing a dilute urine (300 mOsm/kg) and abundant urine sodium (80 mEq/L). Loop diuretics may produce a similar picture even in the face of hypovolemia. (unboundmedicine.com)
