Answer

Formation of Foetus
First, it is important to understand that the development of a fetus is a complex process that occurs in stages. Here is the order in which the mentioned structures are formed:

Heart
- The heart is one of the first organs to form in a developing fetus. It starts to develop and beat as early as 3 weeks after conception.
- The heart is crucial for supplying oxygen and nutrients to the growing fetus, so its early formation is essential for the overall development of the baby.

Limbs and Digits
- Limbs and digits start to form around the 5th week of pregnancy. Initially, they appear as small buds that eventually grow and differentiate into arms, legs, fingers, and toes.
- The development of limbs and digits is important for the baby's mobility and interaction with the environment.

Eye Lids
- Eye lids typically start to form around the 11th week of pregnancy. Initially, they are fused shut to protect the developing eyes.
- As the fetus continues to grow, the eye lids separate and become functional, allowing the baby to blink and protect their eyes.

Hairs on Head
- Hair on the head is one of the last structures to form in a developing fetus. Hair follicles start to develop around the 14th week of pregnancy, but the hair itself may not be visible until much later in the pregnancy.
- Hair on the head serves various functions, including insulation and protection for the baby.
In conclusion, the heart is formed first in a growing fetus, followed by limbs and digits, eye lids, and finally hairs on the head. Each of these structures plays a vital role in the overall development and well-being of the baby.
