Foetal

Foetal (or fetal) refers to anything pertaining to a fetus, which is the developmental stage of a mammal following the embryonic stage and before birth. In humans, the fetal stage begins at the end of the 8th week after fertilization and continues until birth.

Development

The fetal stage is characterized by significant growth and development. During this period, the fetus undergoes extensive organogenesis, where all major organs and systems are formed and begin to function. The central nervous system, cardiovascular system, and musculoskeletal system are among the critical systems that develop during this stage.

First Trimester

In the first trimester, the fetus grows from a single cell to a complex organism. By the end of the first trimester, the fetus has a recognizable human form, with the development of the brain, spinal cord, and heart.

Second Trimester

During the second trimester, the fetus continues to grow and develop. The skeletal system begins to harden, and the fetus starts to move. The skin becomes more opaque, and hair begins to grow.

Third Trimester

In the third trimester, the fetus undergoes rapid growth. The lungs mature, and the fetus gains weight. By the end of this trimester, the fetus is typically ready for birth.

Health and Monitoring

Monitoring fetal health is crucial for ensuring a healthy pregnancy. Common methods include ultrasound, amniocentesis, and non-stress tests. These tests help in assessing the growth, development, and well-being of the fetus.

Complications

Several complications can arise during the fetal stage, including fetal distress, intrauterine growth restriction, and congenital anomalies. Early detection and management of these conditions are essential for the health of both the fetus and the mother.
