Multiple Choice

Which of the following correctly describes the process of glomerular filtration?

It involves the selective reabsorption of water and solutes from the filtrate back into the blood.

It involves the secretion of waste products from the blood into the renal tubule.

It is the active transport of sodium ions from the filtrate into the renal tubule cells.

It is the process by which blood pressure forces water and solutes through the glomerular capillaries into Bowman's capsule.

Verified step by step guidance

Understand the location and function of the glomerulus in the kidney. The glomerulus is a network of capillaries located at the beginning of a nephron, and its primary function is filtration of blood.

Recognize the role of blood pressure in glomerular filtration. Blood pressure in the glomerular capillaries forces water and solutes out of the blood and into Bowman's capsule, forming the filtrate.

Differentiate glomerular filtration from other renal processes. Unlike selective reabsorption or secretion, glomerular filtration is a passive process driven by blood pressure, not active transport.

Identify the components of the filtrate. The filtrate includes water, ions, glucose, amino acids, and waste products, but excludes larger molecules like proteins and blood cells.

Clarify the pathway of the filtrate. After filtration, the filtrate moves through the renal tubule where selective reabsorption and secretion occur, further modifying its composition before excretion.
