Final answer:
All the following are considered organs of excretion except the adrenal gland (Option A) They secrete hormones rather than waste products. Organs of excretion include the skin, liver, large intestine, and lungs.
Step-by-step explanation:
All the following are considered organs of excretion except a) the adrenal glands. Excretion is the process of removing wastes from the body.
- The skin excretes wastes through the production of sweat, which includes water, salts, and a small amount of urea.
- The liver plays a crucial role in excretion by breaking down substances and toxins in the blood and excreting them, such as bilirubin in bile.
- The large intestine is responsible for the excretion of solid waste after the digestion of food and extraction of water.
- The lungs excrete gaseous wastes, primarily carbon dioxide and water vapor from cellular respiration.
The adrenal glands are not traditionally considered part of the excretory system as their primary function is to secrete hormones like adrenaline and cortisol, not excrete waste products.
Hence, the correct answer is Option A.
