You're welcome.

The kidney tubules are part of the urinary system, also known as the renal system. This system consists of the kidneys, ureters, urinary bladder, and urethra. The primary function of the urinary system is to remove waste products and excess water from the body in the form of urine.

To complete your chart, you need to determine which organ system each organ belongs to. Here's a step-by-step guide to help you find the answers:

1. Research each organ mentioned in your chart.
2. Identify the main function or purpose of each organ.
3. Refer to a reliable source such as a textbook or reputable website about human anatomy to find the organ system that each organ belongs to.
4. Fill in the chart accordingly, checking off the correct organ system for each organ.

Remember to use reliable sources and double-check the information to ensure accuracy. If you encounter difficulties with any specific questions on your chart, feel free to ask for help on those specific questions.
