Verified step by step guidance

Understand that the kidneys play a crucial role in maintaining homeostasis, particularly in regulating blood volume and blood pressure.

Recognize that the kidneys filter blood through structures called nephrons, which remove waste products and excess substances from the bloodstream.

Learn that during the filtration process, the kidneys reabsorb water and essential electrolytes back into the bloodstream, which helps to control blood volume.

Acknowledge that the regulation of blood volume by the kidneys directly influences blood pressure, as increased blood volume can lead to higher blood pressure.

Note that the kidneys also release the enzyme renin, which is part of the renin-angiotensin-aldosterone system (RAAS), a hormone system that regulates blood pressure and fluid balance.
