Het menselijk lichaam is een loom boek, een traag boek, er worden veel woorden gebruikt, maar weinig verteld. Het bezorgde mij weer een ongemakkelijk gevoel. Misschien is dat wel de bedoeling van de schrijver en dan verdient hij 5 sterren!

The primary purpose of the reproductive system is to produce new humans in the form of children and ensure their sexual development so that they can produce new humans too. It is composed of the gonads ( testicles and ovaries) which produce eggs and sperm cells ( gametes) and produce hormones necessary for proper sexual development. The rest of the glands and ducts of the reproductive system are responsible for the transportation and sustaining of the gametes and to nurture the offspring. [40] Frausto Da Silva, J. J.

The first part of the story is a series of character studies that are as boring to read as the wait for something to happen in war. They squabble. They joke. They are unlikable, pathetic, trying to be emotionally torn but coming across as self-important. They are, unfortunately, uninteresting.

The appendix is a narrow pouch attached to the lower abdominal cavity of the human body. It’s generally considered to be redundant in the function of the human body, however, in 2017 research conducted by Midwestern University suggested that the appendix may serve as a reservoir for several types of beneficial gut bacteria.
