Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell div
iragen [17]

The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.

The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:

  • Zygote: Fertilized ovum.
  • Blastocyst: Cluster of cells that is the result of the zygote going through cell division.
  • Embryo: Unborn human that is still developing, usually before the 8th week of gestation.
  • Fetus: Unborn human in development after the 8th week of gestation.

Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

Eric follows a vegetarian eating pattern, and he wants to know whether he needs to take any vitamin and mineral supplements. wha
Reil [10]

It would be most important for Eric to find out his <em>zinc, iron and vitamin B12 (or  riboflavin) levels, and ensure that he is obtaining adequate amounts of these vitamins and minerals through vegetarian sources </em>.

A vegetarian diet is typically low in zinc rich foods, since meat, shell fish and eggs are the most abundant sources of zinc. In order to ensure that he obtains sufficient zinc, Eric should make sure he consumes vegetarian zinc sources such as legumes, lentils, dairy, nuts and seeds on a daily basis.

Since iron and vitamin B12 are also difficult to obtain from vegetarian sources, Eric should consume iron rich foods such as spinach, kale, whole grains, broccoli, legumes,etc., on a daily basis. As for vitamin B12, daily supplementation of 2.4 μg is recommended for vegetarians. Alternatively, riboflavin fortified cereals and grains are also recommended to meet daily riboflavin requirements.
