Question

During human gestation, organogenesis occurs ______.

विकल्प

• in the first trimester

• in the second trimester

• in the third trimester

• during the blastocyst stage

Answer 1

During human gestation, organogenesis occurs in the first trimester.

Explanation:

• Organogenesis, the process of organ formation from the three germ layers, occurs primarily in the first trimester of human gestation.
• This period is crucial as all major organs begin to develop during this time.
• Organogenesis does not happen during the blastocyst stage nor later in the second or third trimester, which involve growth and maturation rather than initial organ formation.
