Calyx is a term used in animal anatomy for some cuplike areas or structures. ... (in crinoids and ophiuroids the main part of the body where the viscera are located). [2]
The renal calyces (sg. calyx) are conduits in the kidney through which urine passes. The minor calyces form a cup-shaped drain around the apex of the renal pyramids.Urine formed in the kidney passes through a renal papilla at the apex into the minor calyx; four or five minor calyces converge to form a major calyx through which urine passes into the renal pelvis (which in turn drains urine out ...
Calyx (botany), the collective name for the sepals of a flower; Calyce, a genus of beetles; Calyx, a genus of sea sponges; Calyx of Held, a large synapse in the auditory brainstem structure; Eubela calyx, species of sea snail; Renal calyx, a chamber in the kidney that surrounds the apex of the renal pyramids
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
The calyx of Held is a part of the auditory system, connecting the globular bushy cells (GBCs) of the anteroventral cochlear nucleus to the principal neurons of the medial nucleus of the trapezoid body (MNTB).
Like the bony pelvis, the renal pelvis (/ ˈ r iː n əl ˈ p ɛ l v ɪ s /) gets its English name via Neo-Latin from the older Latin word pelvis, "basin", as in "wash basin". [4] In both cases the name reflects the shape of the structure, and in the case of the renal pelvis, it also reflects the function.
The lungs are the part of respiratory system which helps to maintain acid–base homeostasis by regulating carbon dioxide (CO 2) concentration in the blood. The respiratory system is the first line of defense when the body experiences and acid–base problem. It attempts to return the body pH to a value of 7.4 by controlling the respiratory rate.
A renal corpuscle (or Malpighian body [1]) is the blood-filtering component of the nephron of the kidney. It consists of a glomerulus - a tuft of capillaries composed of endothelial cells - and a glomerular capsule known as Bowman's capsule .
