Answer

Formation of Urine

GLOMERULAR FILTRATION

The first step in urine formation is glomerular filtration. In this step, blood is filtered in the glomerulus of the nephron. The glomerulus is a network of capillaries surrounded by Bowman's capsule. The blood pressure forces the plasma and other small molecules out of the capillaries and into the Bowman's capsule. This filtrate contains water, ions, glucose, and waste products such as urea and creatinine.

TUBULAR REABSORPTION

The second step in urine formation is tubular reabsorption. In this step, the filtrate is transported through the tubules of the nephron. As the filtrate passes through each segment of the tubules, essential substances such as glucose and ions are reabsorbed into the blood. This process is important for maintaining the body's fluid and electrolyte balance.

TUBULAR SECRETION

The final step in urine formation is tubular secretion. In this step, waste products and excess ions are secreted from the blood into the tubules. This process helps to remove excess waste products such as urea and creatinine from the body.

CONCENTRATION OF URINE

After the urine is formed, it passes through the collecting ducts where it is further concentrated. This is done by reabsorbing water from the urine into the blood. The concentration of urine is controlled by the antidiuretic hormone (ADH), which is produced by the hypothalamus and released by the pituitary gland. ADH increases the permeability of the collecting ducts to water, allowing more water to be reabsorbed from the urine.

EXCRETION OF URINE

After the urine is concentrated, it is excreted from the body through the urethra. The amount and composition of urine excreted from the body is dependent on various factors such as fluid intake, diet, and physical activity. The kidneys play a crucial role in maintaining the body's fluid and electrolyte balance, and any dysfunction in the kidney can lead to various health problems.
