(B) Near the buccal cavity
(C) Near the heart
(D) Outside the coelom

Answer 1

Hint: Kidney is the main excretory organ that removes the liquid metabolic waste product in the body as the urine. Every kidney has around millions of the small filters called nephrons. It is called the unit of the kidney. Humans are the ureotelic organisms.

Complete Answer:
- The kidneys are a couple of bean-formed organs on either side of your spine, underneath your ribs and behind your stomach. It is located outside the body cavity or the coelom. Every kidney is around in length, generally the size of a huge clench hand.
- The kidneys' main responsibility is to purify your blood. They eliminate wastes, control the body's liquid balance, and keep the correct degrees of electrolytes.
- The entirety of the blood in your body goes through them a few times each day. Blood comes into the kidney, metabolic wastes get eliminated, and salt, water, and minerals are balanced, if necessary.
- The shifted blood returns into the body. Wastes get transformed into the urine, which gathers in the kidney's pelvis - a pipe formed structure that channels down a cylinder called the ureter to the bladder. And it is discharged to the external environment through the urethra.

Thus the option (D) is correct.

Note: When the kidney fails to function, it is kidney failure. It is mainly due to the high blood pressure, high blood sugar level, any possible damage to the kidney’s filter or the kidney stone. The kidney failure is found by taking the blood test. If there is more creatinine level in the blood then it is the symptoms of the kidney failure.
