Question

question:
name the excretory organ responsible for converting ammonia and
filtering waste out of the body.

answer options:
select one of four
trachea
kidney
lung
heart

Explanation:

To solve this, we analyze each option:

• Trachea: Part of the respiratory system, not excretory.
• Kidney: Excretory organ that filters waste (like converting ammonia to urea) and removes it from the body.
• Lung: Excretes carbon dioxide (respiratory waste), not involved in converting ammonia or filtering typical metabolic waste like kidneys.
• Heart: Circulatory organ, not excretory.

So the kidney is the correct excretory organ for this function.

Answer:

B. Kidney (assuming the options are labeled as A. Trachea, B. Kidney, C. Lung, D. Heart; if labels differ, adjust but the correct option is the one with "Kidney")
