Final answer:
Items in the blood that are not filtered in the glomerulus of the kidney nephron travel through the efferent arteriole. Filtration involves the movement of water and solutes from blood under pressure into Bowman's capsule and then into the proximal convoluted tubule. Option c is the correct answer.
Step-by-step explanation:
Filtration in the kidneys involves blood from the afferent arteriole flowing through the glomerular capillaries under pressure, leading to water and solutes being filtered into Bowman's capsule. This filtration process includes various substances such as water, salts, nutrients, and wastes like urea, which then pass into the proximal convoluted tubule of the nephron. Blood components not filtered in the glomerulus will travel via the efferent arteriole.
The nephron is the functional unit of the kidney, consisting of a glomerulus and a renal tubule. The glomerulus is a network of capillaries where blood filtration occurs, and upon exiting the glomerulus, the blood travels through the efferent arteriole. This efferent arteriole eventually forms a secondary capillary network around the more distal parts of the nephron, such as the peritubular capillaries and vasa recta.
Given the options in the question and based on the filtration process within the kidneys, the correct choice for where items in the blood that are not filtered will travel from the glomerulus to is the efferent arteriole (Option C).
