⭕️Lungs excrete carbon dioxide and water vapour formed during the process of respiration.

✔️✔️Skin

⭕️Skin removes urea, salts and excess water as sweat produced by sweat glands present in the skin.

⭕️Sweat is removed through tiny pores in the skin.

✔️✔️Large intestine

⭕️Large intestine removes the indigested food as faeces through the anus.

⭕️It is a storage area of waste material that waits for being eliminated.

✔️✔️Urinary system

⏹Excretion is the process by which waste products of metabolism and other non-useful materials are eliminated from an organism.

⏹Plants excrete through photosynthesis where oxygen is given as a waste product; and transpiration where excess water is getting rid.

⏹Waste products stored in leaves may also fall off.
