Question

draw any one accessory excretory organ that you
have studied?​

Answer 1

One accessory excretory organ is the SKIN.

But how does it help in excretion?

• In our body, kidney is the main organ of excretion which helps us to excrete out majority of the the toxins by-products and drugs in the blood.

• However, skin also acts as an important accessory organ in excreting out a number of substances.

• Majority of heavy metals like arsenic and mercury are excreted out through the skin.
