Dear Journal,
This is my journal for this week. The topic that we tackled was about the excretory system.
I learned that excretion is the process by which metabolic wastes like nitrogenous compounds are eliminated by the body. I have read also some things about the exretory system. I knewed that the reason the principal excretory organs are not the intestines is that the vast majority of the contents of the stool was never in the body in the first place. The gastrointestinal tract is actually outside the body per se.However, a small portion of the fecal matter contains actual waste material from the inside of the body. This is primarily the bile, which is formed in the liver, passes into the gallbladder, and thence into the intestines via the bile duct. The importance of the excretory system is that waste, if not disposed of, would poison the body.
We must take good care of our exretory system.
