The compound microscope was invented 40 years before Anton van Leeuwenhoek was born. He employed a simple microscope with lenses he invented around 1670.
Anton van Leeuwenhoek invented a method for making small spherical lenses that much increased magnification of microscopes.
No-one invented the human cell.
Actually Antonie Philips van Leeuwenhoek discovered cells in 1673. He called those cells as animalcules.He observed and described several of these life forms, including bacteria, before anyone else knew of their existence.
He used a microscope to look at blood
1676.
1670
The concept of cells was first proposed by Robert Hooke in 1665, who observed cellular structure in cork. However, the discovery of the actual human cell came much later. In the 19th century, several scientists including Matthias Schleiden and Theodor Schwann contributed to the development of the cell theory, which stated that all living organisms are composed of cells.
Antonie van Leeuwenhoek is likely the first person to observe a cell nucleus. To the best of my knowledge, no human has actually a seen an atomic nucleus. Cameras and microscopes aren't yet powerful enough to observe those.
In 1676 Van Leeuwenhoek found bacteria while viewing scrapings from human teeth, including his own. He called the bacteria that he saw in his microscope "animalcules".
Antony van Leeuwenhoek (1632-1723) discovered bacteria, free-living and parasitic microscopic protists, sperm cells, blood cells, microscopic nematodes and rotifers, and much more with the microscopes he made. He referred to these organisms as animalcules. His research, which was widely circulated, opened up an entire world of microscopic life to the awareness of scientists.

Human bodies were not 'invented'.
Leeuwenhoek's main discoveries are:the infusoria (protists in modern zoological classification), in 1674the bacteria, (e.g. large Selenomonads from the human mouth), in 1676the spermatozoa in 1677. Van Leeuwenhoek had troubles with Dutch theologists about his practice.the banded pattern of muscular fibers, in 1682
