Question
Which of the following is an organ of the excretory system?
- Urinary bladder
- Ureters
- Kidney
- All of these
Hint:
The excretory system is responsible for removing waste material from the body.
The correct answer is: All of these
- All of the above-mentioned options are a part of the excretory system.
- The body needs to have a system that ensures the proper removal of waste substances. This function is carried out by the excretory system.
- It consists of the kidneys, ureter, urinary bladder, and urethra.
- Kidneys, being the main organ ensure the removal of all waste substances from the blood and form urine. They also maintain the osmotic balance of the body.
- The ureter is a long tube-like structure, which connects the kidneys to the urinary bladder. The urine passes through the ureter to the urinary bladder.
- The urinary bladder is a pouch-like organ in the lower abdomen. It stores the urine for a decent amount of time till it is passed out.
- The urethra is a small opening in this system through which the urine or the waste material is passed out of the body.
The urinary bladder has sensors that direct the brain to empty itself when the pressure rises.
