Question

respiratory and excretory system
tying your knowledge together...

1. describe how the respiratory and excretory system work with one another.
2. what other human body system works with these systems to ensure your body works correctly?

Explanation:

1. The respiratory system takes in oxygen and releases carbon dioxide. The excretory system (especially the kidneys) filters waste from the blood, including nitrogenous wastes. The respiratory system helps in removing carbon dioxide (a waste product) which is also a task related to excretion. The blood (which is part of the circulatory system that works with both) carries carbon dioxide from cells to the lungs (respiratory system) for exhalation and also carries waste to the excretory organs.
2. The circulatory system works with both. It transports oxygen (from the respiratory system) to cells and nutrients. It also transports waste (like carbon dioxide to the lungs and other wastes to the excretory system). The nervous system can regulate the functions of both systems (e.g., controlling breathing rate in the respiratory system and kidney function in the excretory system to some extent).

Answer:

1. The respiratory system excretes carbon dioxide (a waste) while the excretory system (like kidneys) filters other wastes. Blood (circulatory) links them, carrying waste to respective systems.
2. Circulatory system (transports substances for both), Nervous system (regulates functions).
