Verified step by step guidance

Understand the physiological changes during pregnancy: Pregnancy leads to increased blood volume and cardiac output, which affects kidney function and filtration rate.

Recall the role of the kidneys: The kidneys filter blood through structures called nephrons, which are responsible for maintaining fluid and electrolyte balance.

Analyze the filtration rate: During pregnancy, the increased blood volume and cardiac output result in an increased glomerular filtration rate (GFR). This is due to the higher demand for waste removal and fluid regulation.

Consider the number of nephrons: The number of nephrons in the kidneys is fixed from birth and does not change during pregnancy. Instead, the existing nephrons work more efficiently to accommodate the increased filtration demands.

Match the correct answer: Based on the physiological changes, the filtration rate increases, and the number of nephrons remains the same during pregnancy.
