Nephrons: Function of the Various Segments of the Renal Tubule Proximal Convoluted Tubule (PCT). This is the first part of the renal tubule and it lies in the cortex of the kidney, close to the renal corpusle. Fluid that is filtered from the Bowman’s Capsule enters into the proximal tubule.

Urinary System Chapter 17 substances are transported out of the tubular fluid through the epithelium of the renal tubule, and into the interstitial fluid (the substances must first cross the cell membrane then to the inter. fluid). Then these substances diffuse into the peritubular capillaries. - Tubular reabsorption returns substances to the internal environment.

Protrusio acetabuli Protrusio acetabuli. Radswiki et al. Acetabular protrusio (also known as acetabular protrusion) is intrapelvic displacement of the acetabulum and femoral head, so that the femoral head projects medial to the ischioilial line. It should be differentiated from coxa profunda.

The Renal Tubule: Definition, Function & Terms Ultrafiltrate flows through the first part of the renal tubule, called the proximal convoluted tubule, which is a section of the renal tubule mainly located in the kidney's cortex that is responsible for the reabsorption of the majority of ultrafiltrate.The ultrafiltrate will then flow into the loop of Henle.he word 'proximal' in 'proximal convoluted tubule' implies it's near or attached to the renal corpuscle, and if you look at the image on your screen, you can also see how convoluted this duct is due to a bunch of twists and turns.

Decubitus Ulcer - staging, symptoms and treatment Decubitus Ulcer - staging, symptoms and treatment | Health Dictionary. Decubitus Ulcer - An erosion in the SKIN that results from the pressure of remaining in one position for an extended period of time, commonly called a bedsore or pressure sore. The extended pressure deprives the tissue of blood circulation, allowing cells to die and the tissue to break down.

Medical Student Curriculum: Hematuria DEFINITION. Hematuria is defined as the presence of red blood cells in the urine. When visible to the patient, it is termed gross hematuria and is usually alarming to patients. Microscopic hematuria is that detected by the dipstick method or microscopic examination of the urinary sediment.he source of red blood cells in the urine can be from anywhere in the urinary tract between the kidney glomerulus and the urethral meatus (Figure 2). Figure 2. Human urinary tract anatomy that is at risk when hematuria is found.

- 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.luid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. This is driven by sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells.

- Peritubular capillaries. In the renal system, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron.

Definitions &Translations It is termed reabsorption because the fluid and other substances that are reabsorbed from the bloodstream through the glomerulus into Bowman's capsule, which leads to the peritubular capillaries.his happens as a result of sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells. Thus, the glomerular filtrate becomes more concentrated, which is one of the steps in forming urine.

- TYPES OF HEMATURIA. There are two main types of hematuria: gross and microscopic. ●Gross hematuria – Gross hematuria means that you can see blood with the naked eye because the urine is pink, red, purplish-red, brownish-red, or tea-colored. If you see blood in your urine, you should call your healthcare provider.
