Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels. [6] Xylem also contains two other type of cells: parenchyma and fibers. [7] Xylem can be found: in vascular bundles, present in non-woody plants and non-woody parts of woody plants
Anatomical terminology. [ edit on Wikidata] The renal circulation supplies the blood to the kidneys via the renal arteries, left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output. [ 1]
A vessel element or vessel member (also called a xylem vessel) [ 1] is one of the cell types found in xylem, the water conducting tissue of plants. Vessel elements are found in most angiosperms ( flowering plants) but absent from most gymnosperms such as conifers. Vessel elements are the main feature distinguishing the "hardwood" of angiosperms ...
Kidney. In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organs [ 1] that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. [ 2][ 3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres ( 41⁄2 inches) in ...
Function. Diagram outlining movement of ions in nephron, with the collecting ducts on the right. The collecting duct system is the final component of the kidney to influence the body's electrolyte and fluid balance. In humans, the system accounts for 4–5% of the kidney's reabsorption of sodium and 5% of the kidney's reabsorption of water.
Before reaching the hilus of the kidney, each artery divides into four or five branches. The anterior branches (the upper, middle, lower and apical segmental arteries) lie between the renal vein and ureter, the vein being in front, the ureter behind. The posterior branches, which are fewer in number and include the posterior segmental artery ...
Lumen (anatomy) Cross section of the gut. The lumen is the space in the middle also known as the volume. Normal histology of the breast, with lumen annotated at bottom right. In biology, a lumen ( pl.: lumina) is the inside space of a tubular structure, such as an artery or intestine. [ 1] It comes from Latin lumen 'an opening'. It can refer to:
Latin. corpusculum renis. FMA. 15625. Anatomical terminology. [ edit on Wikidata] 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.
