Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small intestine into the cell, then into the blood. The pedicels increase the surface area of the cells enabling efficient ultrafiltration.. Podocytes secrete and maintain the basement Distal Convoluted Tubule. This digital textbook provides comprehensive, system-specific text as well as high-resolution, annotated images along with chapter-specific glossary of terms and learning objectives.
Histology. Excretion of Hydrogen (H +) Ions. The convoluted distal tubule projects into the cortex. The kidney in general and the proximal and distal tubules in particular, grow large from the onset of diabetes with the proximal tubule accounting for the greatest share of growth (116, 510, 511, 571). Both parts of the distal tubule are composed of simple cuboidal epithelium, similar in morphology to the proximal tubule. The glomerulus (plural 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. Even though it is short, it plays a key role in regulating extracellular fluid volume and electrolyte homeostasis. Histology. The medullary interstitium is the tissue surrounding the loop of Henle in the medulla.
The proximal convoluted tubule avidly reabsorbs filtered glucose into the peritubular capillaries so that it is all reabsorbed by the end of the proximal tubule. The foot processes known as pedicels that extend from the podocytes wrap themselves around the capillaries of the glomerulus to form the filtration slits. The capsule and tubule are connected and are composed of The urethra (from Greek ourthr) is a tube that connects the urinary bladder to the urinary meatus for the removal of urine from the body of both females and males. Distal Convoluted Tubule. The medullary interstitium is the tissue surrounding the loop of Henle in the medulla. The mechanism for glucose reabsorption was described in Chapter 7.4. The first stage of the RAAS is the release of the enzyme renin.Renin released from granular cells of the renal juxtaglomerular apparatus (JGA) in response to one of three factors:. The nephron is the minute or microscopic structural and functional unit of the kidney.It is composed of a renal corpuscle and a renal tubule.The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule.The renal tubule extends from the capsule. Liver Histology. The foot processes known as pedicels that extend from the podocytes wrap themselves around the capillaries of the glomerulus to form the filtration slits. The proximal convoluted tubule (PCT) has a high capacity for reabsorption, hence it has specialised features to aid with this.It is lined with simple cuboidal epithelial cells which have a brush border to increase surface area on the apical side. Dont forget to learn the detailed histological features of kidney corpuscles with description. Structure. The distal convoluted tubule (DCT) is a short nephron segment, interposed between the macula densa and collecting duct.

This article will discuss both forms of bone ossification, and will consider the clinical relevance of this important physiological process. Bone ossification is the formation of new bone, which begins as an embryo and continues until early adulthood. They can be distinguished from the vasa recta by the absence of blood, and they can be distinguished from the thick ascending limb by the thickness of the epithelium. They can be distinguished from the vasa recta by the absence of blood, and they can be distinguished from the thick ascending limb by the thickness of the epithelium.
