Renal system physiology
3B: If you want to learn more about the renal system, then urine the right place! (Pun aside, the kidneys are about more than just making urine). Every thirty minutes, your kidneys filter the entire blood supply in your body. Imagine a dirty pool filled with algae. Placing a filter in this pool will cause the algae to be flushed out, and after a time you’ll have a clean, crisp blue pool to enjoy. Just like the filter for a pool, our kidneys filter the blood and remove toxic wastes. These paired organs are key to maintaining electrolyte and water homeostasis in your body.

What homeschoolers say about Khan Academy
Homeschoolers widely appreciate Khan Academy for its extensive free resources covering a broad range of subjects and grade levels, including test prep and advanced topics. Many praise its clear video lessons and interactive exercises that allow self-paced learning. However, some families find the platform less structured and requiring significant parental oversight to ensure consistent progress. Additionally, while the content quality is generally high, a few users note that the presentation can feel dry or overly academic for younger learners. Overall, Khan Academy is valued for accessibility and depth but may need supplementation for a fully rounded homeschool curriculum.
