The Urinary System is important in Anatomy and Physiology because it builds foundational knowledge of Introduction to Urinary System and related concepts needed for further study. The renal system plays an important role in homeostasis and its function is to filter approximately 200 litres of fluid each day and allow excretion of toxins and metabolic waste while keeping essential substances in the blood, supporting electrolyte balance. This article examines the external and internal anatomy of the kidneys, and discusses the process of urine production and homeostasis of blood volume and pressure through examination of nephron Renal system, in humans, organ system that includes the kidneys, where urine is produced, and the ureters, bladder, and urethra for the passage, storage, and voiding of urine. View detailed illustrations of the kidneys, bladder, and other urinary system structures. Three principal functions of the nephron are filtration, reabsorption, and secretion. This allows for exchange of chemical messengers between the different cell types. The kidneys form urine, and the ureters carry the urine away from kidneys to the urinary bladder, where it is stored until it is expelled during urination. Today we're talking about the anatomy of your urinary system, and how your kidneys filter metabolic waste and balance salt and water concentrations in the blood. Although parts of the renal tubules are named proximal and distal, in a cross-section of the kidney, the tubules are placed close together and in contact with each other and the glomerulus.

Control of extracellular fluid volume (ECF) and regulation of renal NaCl excretion To maintain ECF volume, the body monitors the volume of this compartment and, in response to changes, signals the kidneys to make appropriate adjustments in NaCl excretion. The kidney has a variety of tools that it can employ in order to compensate for different acid-base disturbances. Having more RBCs allows the blood to transport more oxygen. Urinary System Function Regulates RBC Production If oxygen levels in the blood are low, the kidneys release erythropoietin, a hormone that stimulates the hemocytoblasts (stem cells in the bone marrow) to increase red blood cell formation. Reabsorption and secretion by the kidney tubules Activity 1 – Introduction to the Urinary System Anatomy Use the information shown in this YouTube video about the urinary system to complete this laboratory activity on the Urinary System. Special attention is given to the cell types and structural aspect of the nephron, the functional unit of the kidney. Learning the anatomy of the kidney is essential when trying to under how disease processes a A counter current multiplier system is an arrangement by which the high medullary interstitial concentration of solute is maintained, giving the kidney the ability to concentrate urine. In this video, Dr Mike explains what components of filtrate get "reabsorbed" back into the body and what components of blood get "secreted" into the tubules Kidneys also maintain an acid-base balance by secreting excess H + ions. The male kidney is typically a bit larger than the female kidney. In humans and placental mammals, it consists of the kidneys, ureters, bladder, and the urethra. The urinary system, also known as the urinary tract or renal system, is a part of the excretory system of vertebrates.
