What stage of development occurs when organs and critical body structures are formed?
Understand the Problem
The question is asking about the specific stage of development during which organs and critical body structures are formed. It presents multiple-choice options to identify which development stage corresponds to this process.
Answer
The process occurs during the embryonic stage, weeks 3-8.
The formation of organs and critical body structures occurs during the embryonic stage, specifically from weeks 3 to 8 of pregnancy. This phase is known as organogenesis.
Answer for screen readers
The formation of organs and critical body structures occurs during the embryonic stage, specifically from weeks 3 to 8 of pregnancy. This phase is known as organogenesis.
More Information
In human development, the embryonic stage is crucial as it is when most of the basic organ systems are formed, a process known as organogenesis. This sets the foundation for further development during pregnancy.
Tips
A common mistake is confusing the embryonic period with the fetal period, which follows after organ formation has begun.
