The Amazing Human Excretory System

What are the main excretory organs in the human body?

1. Skin
2. Lungs
3. Large Intestine

Answer:

The main excretory organs in the human body are the skin, lungs, and large intestine.

The human excretory system plays a vital role in maintaining the body's internal environment. Let's explore the functions of each excretory organ:

Skin

The skin excretes sweat, which is made up of water, salts, and chemicals like urea. Sweat helps regulate body temperature and removes waste products from the body through pores on the skin.

Lungs

The lungs excrete carbon dioxide and water. During cellular respiration, the lungs remove carbon dioxide, a waste product of metabolism, and release it into the atmosphere. The exhalation of water vapor also helps eliminate waste from the body.

Large Intestine

The large intestine produces feces, which is then stored in the rectum before being excreted through the anus. Feces contain undigested food, bacteria, and other waste materials from the digestive process.
