Biology - How the Kidneys Work - (Kidneys Part 1/3) #27

The video explains the kidneys' roles in filtering blood, removing waste like urea, and regulating ions and water. It details the processes of filtration and selective reabsorption in the nephrons. The video also covers how the hypothalamus and pituitary gland regulate water levels through ADH, maintaining balance via a negative feedback loop.

What happens to cells when there is too much or too little water in the body?

What is selective reabsorption in the kidneys?

Explain the concept of a negative feedback loop in the context of water regulation.
