which organ forms in the third trimester? kidneys ears lungs heart
Answer
Brief Explanations:
- Kidneys start to form earlier in fetal development.
- Ears also begin their development well before the third trimester.
- The heart is one of the first organs to form in embryonic development.
- Lungs undergo significant development and maturation in the third trimester. Surfactant production (important for lung function - preventing alveoli from collapsing) ramps up, and the lung tissue continues to develop to prepare for breathing air at birth.
