Verified step by step guidance

Understand the function of the nephron: The nephron is the functional unit of the kidney, responsible for filtering blood and forming urine.

Identify the processes involved in urine formation: The main processes are glomerular filtration, tubular reabsorption, tubular secretion, and excretion.

Recognize the sequence of these processes: Glomerular filtration is the first step, followed by tubular reabsorption, tubular secretion, and finally excretion.

Define glomerular filtration: This process occurs in the glomerulus, where blood pressure forces water and solutes out of the blood and into the Bowman's capsule, forming the initial filtrate.

Differentiate glomerular filtration from other processes: Unlike tubular reabsorption and secretion, which involve the movement of substances between the filtrate and blood, glomerular filtration is solely about filtering blood to form the initial urine filtrate.
