Option 2 : Kidney
- Human Excretory system is responsible for removing waste and to maintain salt-water balance in the body.
- During the normal metabolism of the body especially breaking down of protein nitrogenous waste is produced such as urea.
- Here kidney plays an important role in the purification of blood by removing the wastes. It removes the urea which is excreted out and blood goes back to the heart again.
- Excess water is flushed out in the form of urine but the kidney helps the body to retain the necessary amount of water.
- When normal kidney functioning is abrupt then the patient has to go through an external dialysis process to maintain blood purification and flush out toxic wastes.
- Lungs are the primary organ helping in the respiration process while the pancreas secretes insulin which helps to control body sugar
