The Taq-i Kisrais a Sassanid-era Persian monument and the only visible remnant of the ancient city of Ctesiphon. It is the largest brick built arch in the world and located near the modern town of Salman Pak, Iraq.

Human kidney proximal tubule.
This is a SEM picture of a human proximal tubule, showing the tubular structure and projections extending over the tissue surface. The proximal tubule is the portion of the duct system of the nephron of the kidney which leads from Bowman’s capsule to the loop of Henle.
The kidney participates in whole-body homeostasis, regulating acid-base balance, electrolyte concentrations, extracellular fluid volume, and blood pressure. It accomplishes these homeostatic functions both independently and in concert with other organs, particularly those of the endocrine system. Various endocrine hormones coordinate these endocrine functions
Many of the kidney’s functions are accomplished by relatively simple mechanisms of filtration, reabsorption, and secretion, which take place in the nephron. Filtration, which takes place at the renal corpuscle, is the process by which cells and large proteins are filtered from the blood to make an ultrafiltrate that eventually becomes urine. Reabsorption, which takes place at the proximal tube, is the transport of molecules from this ultrafiltrate and into the blood. Secretion is the reverse process, in which molecules are transported in the opposite direction, from the blood into the urine.
