I think for me the process of excretion with the process of defecation is by the process of excretion with the process of defecation. Therefore the defecation is the process of excretion by the process of defecation. Some says excretion is the process with the defecation process. That's why the organ contrast the process of excretion with the process of defecation.
The primary organ of excretion is the kidney. Kidneys filter waste products from the blood to produce urine, which is then excreted from the body.
The organ that excretes Urea compounds are the kidneys, BUT they do not excrete HEAT. No organ of the human body EXCRETES heat.
Excretion in living things is the process of removing waste products, such as carbon dioxide, urea, and excess water, from the body. These waste products are produced during metabolic processes and need to be eliminated to maintain homeostasis and prevent harmful buildup in the body. Organ systems like the lungs, kidneys, and skin play key roles in excretion in different organisms.
Feces is not considered to be a metabolic waste product because the digestive tract is open at both ends and technically, feces has never been inside the body. Feces does contain metabolic wastes, however, and the characteristic smell and color is caused by these metabolic wastes being broken down by the bacterial flora of the large intestine.
The kidney is the primary organ responsible for the formation and excretion of nitrogenous waste in the form of urine. It filters blood to remove waste products and excess substances, which are then concentrated and eliminated from the body in the form of urine.
The rectum is the organ that holds indigestible matter before defecation. Feces are expelled through the anus.
Kidneys
skin
Platypuses have a cloaca, which is used for both excretion and reproduction.
The skin is considered an organ of excretion because it sweats, getting rid of toxins and certain mineral salts.
Worms use their skins for excretion mostly.

The primary organ of excretion is the kidney. Kidneys filter waste products from the blood to produce urine, which is then excreted from the body.
The kidney is the main organ, that is responsible for the excretion of waste products. Other organs of excretion are your liver, lungs and skin.
