If the human body were compared to a city, then the __________ would be the city's sewage treatment plant.?
A. urinary system
B. cardiovascular system
C. lymphatic system

E. epithelial system

Answer 1

Sara,

The best option for this question is A: the urinary system. This is the best option because the urinary system excretes waste from the human body. The remaining systems provide essential functions for our bodies, however their primary functions are not solely to excrete waste from the body.

Hope this helps you in your studies!

Answer 2

Sara,

 

It would be urinary system for following reasons:

 

1. It excretes waste and toxic products through urine, a liquid excretory material.

 

2. Prior to urine formation, the process of filtration retains essential nutrients and proteins in the body and ensures that body does not lose any useful molecules due to improper filtration.

 

cardiovascular system primarily supplies oxygen to body organs and tissues and collect carbon-di-oxide.

 

lymphatic system is involved in immune function.

 

nervous system is involved in neural  function and conduction of impulse.

 

There is no epithelial system, it is a cell layer involved in multiple functions.

 

Hope this helps.

Urinary system is the answer. This is the system that is involved in excretion of waste materials from the blood. It cleans the blood off the harmful and excess materials and stores the same in the urinary bladder awaiting removal.
