Urinary System Animation

The urinary system: kidneys, ureters, bladder, and urethra with expanded view of a nephron and the urine-filled space within a bladder. Urinary system: two kidneys, two ureters, one bladder, one urethra. Also called the excretory, genitourinary (GU), or urogenital (UG) system. Produces, stor...

Structures that affect circulation - kidneys, blood volume and venous tone

By: HWC, Views: 7677

• Kidneys regulate blood volume and blood osmolarity via salt and water reabsorption. • Increased reabsorption increases blood volume and venous return (and CO). • Decreased reabsorption increases urine production, which decreases blood volume and venous return (and CO). • Systemi...

Kidney Stones

By: Administrator, Views: 10505

Kidney stones (renal lithiasis, nephrolithiasis) are hard deposits made of minerals and salts that form inside your kidneys. Kidney stones have many causes and can affect any part of your urinary tract — from your kidneys to your bladder. Often, stones form when the urine becomes concentrate...

Purplish-brown, bean-shaped organs located behind abdominal cavity (retroperitoneal area) on either side of spine, between thoracic vertebrae and lumbar region.

• Kidneys regulate blood volume and blood osmolarity via salt and water reabsorption. • Increased reabsorption increases blood volume and venous return (and CO). • Decreased reabsorption Increases urine production, which decreases blood volume and venous return (and CO). • Systemi...

Angiotensin II - kidneys, adrenal glands and dehydration

By: HWC, Views: 7839

• Angiontensin II targets cells in the proximal convoluted tubule of the nephron. ■ The reabsorption of Na+ and Cl- ions sets up an osmotic gradient favoring the retention of water. • Decreases urine production and increases blood volume and pressure. • Angiontensin II targets zon...

Introduction to Cystic Fibrosis

By: Administrator, Views: 10681

Cystic fibrosis (CF) is a genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. Long-term issues include difficulty breathing and coughing up mucus as a result of frequent lung infections. Other signs and symptoms may include sinus infections, poor ...

ADH and the arterioles, kidneys, sweat glands and the Atrial natriuretic peptide (ANP)

By: HWC, Views: 7817

• ADH is also known as vasopressin. • Produced by hypothalmus and secreted by neurosecretory cells in posterior pituitary gland. • Responds to high blood osmotic pressure representing low amounts of water in the blood. • Binds to smooth muscle cells in walls of arterioles, stimulate...

Structures that affect circulation - venous return

By: HWC, Views: 7557

• Venous return directly affects cardiac output. • Increased venous return leads directly to greater cardiac output whereas decreased return contributes to decreased output. • Venous return depends on: • Blood volume regulation by the kidneys. • Venous tone. • Skeletal muscl...
