Verified step by step guidance

Understand the context: The question is about the process in the kidneys that removes excess water and waste products from the blood.

Identify the key terms: Filtration, Reabsorption, Secretion, and Absorption are processes related to kidney function.

Define Filtration: Filtration is the process by which blood is filtered in the kidneys, specifically in the glomerulus, to remove waste products and excess substances.

Differentiate the processes: Filtration occurs in the glomerulus, Reabsorption involves the movement of substances from the renal tubules back into the blood, Secretion is the transfer of additional waste from the blood into the renal tubules, and Absorption generally refers to the uptake of substances into cells or tissues.

Conclude with the correct process: Filtration is the primary process by which the kidneys remove excess water and waste products from the blood, making it the correct answer.
