Role of Liver in Excretion:

The liver is responsible for the excretion of bilirubin, a waste product of red blood cells. The liver also produces bile, a substance that helps to digest fats. Bile is stored in the gallbladder and released into the small intestine to help digest food. The liver also helps to detoxify the body by breaking down harmful substances.

A Brief on What is Excretion

Excretion is the process of eliminating waste products from the body. The waste products are eliminated through the kidneys, bladder, and bowels.

Role of Kidney in Excretion

The kidneys are responsible for the excretion of urine, which is the waste product of metabolism. The kidneys filter the blood, removing toxins and other waste products. The urine is then transported to the bladder and stored until expelled through the urethra.

Other Excretory Organs of the Body

The urinary system includes the kidneys, ureters, bladder, and urethra. The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the ribcage, one on each side of the spine. The ureters are two thin tubes that run from the kidneys to the bladder. The bladder is a balloon-shaped organ that stores urine. The urethra is a thin tube that carries urine from the bladder to the outside of the body.

Role of Lungs in Excretion

The lungs play an important role in excretion, which is removing waste products from the body. The lungs excrete carbon dioxide, a waste product of metabolism, and water vapor, a by-product of cellular respiration. The lungs also excrete mucus, a sticky secretion that traps bacteria and other particles and helps to keep the airways clear.

Role of Skin in Excretion

The skin is the largest organ in the body, and it performs many important functions, including excretion. The skin excretes sweat, which helps to regulate the body’s temperature. The skin also excretes sebum, which helps to lubricate and protect the skin.

Importance of Other Excretory Organs

The other excretory organs play an important role in excreting wastes from the body. The kidneys are responsible for filtering wastes from the blood and excreting them in the urine. The liver also helps remove waste from the body by secreting bile into the digestive system. The bile helps break down fats and cholesterol in the food and excrete them in the feces.
