Question

the human excretory system is made up of many organs working together to maintain homeostasis. which best describes how the organs that make up the excretory system function?
a. the kidneys, ureter, bladder, and urethra work together to filter and remove the waste products of metabolism.
b. the lungs, pharynx, larynx, trachea, and bronchi work together to exchange gas for the human body to breathe.
c. the heart and blood vessels work together to deliver blood and oxygen throughout the body and remove carbon dioxide.
d. the gastrointestinal tract, liver, pancreas, and gallbladder work together to break down food into nutrients for absorption.

Explanation:

To solve this, we analyze each option:

• Option A: The kidneys, ureter, bladder, and urethra are part of the excretory system. Their function is to filter and remove metabolic waste (like urea), which matches the excretory system's role.
• Option B: The organs listed (lungs, pharynx, etc.) are part of the respiratory system, not excretory.
• Option C: Heart and blood vessels are part of the circulatory system, not excretory.
• Option D: The organs listed (gastrointestinal tract, liver, etc.) are part of the digestive system, not excretory.

So, only Option A correctly describes the excretory system's organs and their function.

Answer:

A. The kidneys, ureter, bladder, and urethra work together to filter and remove the waste products of metabolism.
