What is the process of urination?

When smooth muscle in the wall of the bladder stretches, the micturition reflex (urination) is triggered. Urine produced in the kidneys travels down the ureters into the urinary bladder. The bladder expands like an elastic sac to hold more urine. As it reaches capacity, the process of micturition, or urination, begins.

What is the order of urine flow?

The renal system filters the plasma of blood and regulates blood volume by excreting excess water in the form of urine. Urine transport follows a path through the kidneys, ureters, bladder, and urethra, which are collectively known as the urinary tract.

What is reabsorption in urine formation?

In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood. … Thus, the glomerular filtrate becomes more concentrated, which is one of the steps in forming urine.

What is ultrafiltration How does it occur Class 10?

Ultrafiltration is the removal of fluid from a patient and is one of the functions of the kidneys that dialysis treatment replaces. Ultrafiltration occurs when fluid passes across a semipermeable membrane (a membrane that allows some substances to pass through but not others) due to a driving pressure.

What are the 4 steps of urine formation?

There are four basic processes in the formation of urine starting with plasma.Filtration.Reabsorption.Regulated reabsorption, in which hormones control the rate of transport of sodium and water depending on systemic conditions, takes place in the distal tubule and collecting duct.Secretion.Excretion.

What are the steps of urine formation class 10?

Urine is formed in three main steps- glomerular filtration, reabsorption and secretion. It comprises 95 % water and 5% wastes such as ions of sodium, potassium and calcium, and nitrogenous wastes such as creatinine, urea and ammonia. Osmoregulation is the process of maintaining homeostasis of the body.

Where is urine stored?

The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.

What are the 3 steps in urine formation?

Filtration, Reabsorption, Secretion: The Three Steps of Urine FormationThe Filtration Membrane Keeps Blood Cells and Large Proteins in the Bloodstream. … Reabsorption Moves Nutrients and Water Back into the Bloodstream. … Waste Ions and Hydrogen Ions Secreted from the Blood Complete the Formation of Urine.
