Which organs are involved in elimination?

Answer 1

Excretory System OrgansOrgans that compose the excretory system are those involved in removal of wastes from the body. They include the kidneys, sweat glands, lungs, and rectum, but their primary organs are the kidneys.

A Broad Opinion That Includes Several Organ SystemsThere are several organ systems that are involved in the process of excretion; the pores of the skin that excrete oil and sweat, the lungs which excrete carbon dioxide, the rectum via the anal canal and anus that excretes feces, and the urinary tract which excretes urine via the urethra. An Opinion That Considers Only the Urinary SystemSome anatomists consider the kidneys as the only excretory organ. The filtration of wastes is conducted by nephrons in the renal cortex in special chambers called Bowman's capsules (There are about 1.25 million of them in each kidney) that create filtrate. After the body reabsorbs water, glucose, sodium, and other important products, the remainder is called urine and is collected in the renal medulla. It takes about 25 gallons of blood filtered by the kidneys to produce one day's worth of urine. That is a ratio of about 100 to 1.From here the remaining filtrate (urine) it enters the renal pelvis (a chamber) which leads to the ureters, the bladder, and finally the urethra which allows the urine to be excreted outside the body.
Kidneys, lungs, bowel, skin.

Since you've said organs, I'd have to include skin; however, keep in mind that, although it doesn't seem like it, but the skin is made of many glands and receptors (detectors) alongside other parts: the pores of the skin which excrete sweat produced by sweat glands can be considered the excretory parts.
