Your skin, lungs, and kidneys are all part of the ________ , which removes waste from the body.A.) gallbladder
B.) enzyme process
C.) excretory system
D.) nervous system

Answers

Your skin, lungs, and kidneys are all part of the excretory system, which removes waste from the body.

What is the Excretory system?

The production of waste in the human body follows the production of energy from meals.
The body must get rid of the byproducts of the numerous chemical and physiological processes that are no longer required by the human body.

Excretion is also simple for simple species, such as unicellular organisms, and occurs through the expulsion of gases and water or through diffusion.
Excretion occurs inside human beings' complex bodies as a complex process through an organ system made up of various organs.
Our bodies digest and assimilate the nutrients we receive from a variety of sources.
Our bodies produce energy through the processes of digestion and metabolism, which aid in the absorption of nutrients.
Toxic chemicals are produced as a result of these chemical processes.
The body starts to distinguish between beneficial and harmful chemicals in an individual after metabolic responses.
We are well aware that toxins can accumulate and become hazardous, and the body excretes all metabolic wastes.
These harmful compounds will start to impact the body if they are stored there for an extended period of time.
Therefore, they must be regularly eliminated from the body.
Excretion ensures that the body periodically eliminates the poisonous compounds from the body.
