Question

the excretory system disposes of waste material, like excess liquid and heat energy, from the body. when we talk about the excretory system, were usually referring to the urinary system, which gets rid of liquid waste, or urine. the main organs involved in the excretory system are the kidneys. however, the lungs and the skin are also part of the excretory system because they also dispose of bodily wastes. the respiratory system excretes carbon dioxide, and sweat is excreted through the skin. the process of sweating gets rid of excess heat from the body since the body cools down as the sweat evaporates.

the respiratory system is part of the excretory system because it
choose one option
a disposes of bodily wastes.
b excretes liquid waste dioxide.
c excretes sweat through the skin.
d involves the kidneys.

Explanation:

The text states that the lungs (part of the respiratory system) are part of the excretory system because they dispose of bodily wastes (excrete carbon dioxide). Option A aligns with this as it mentions disposing of bodily wastes. Option B is incorrect as carbon dioxide is a gas, not liquid waste. Option C is about the skin, not the respiratory system. Option D is about the kidneys which are related to the urinary system (a part of the excretory system but not the reason the respiratory system is part of the excretory system).

Answer:

A. disposes of bodily wastes.
