During the developmental stages , in the embryo of all organisms there are particular layers called the germ layers or the embryonic layers
The embryonic layers usually differentiate in the gastrula stage ( it is a stage in the embryonic development)
Now these layers undergo organogenesis to form all our body organs including even our blood
Some organisms have just 2 embryonic layers —> Diploblastic
Organisms with 3 layers —-> Triploblastic
( The three layers are ectoderm , endoderm and mesoderm )
