| Illustration of human lungs highlighting the canalicular stage of development, which occurs between weeks 16 and 26 of gestation. The image shows the trachea branching into bronchi and bronchioles, with a network of blue veins and red arteries. The lung tissue is depicted in a spongy texture, with alveolar sacs forming in the lower right section. This stage is critical for forming the respiratory bronchioles and future gas exchange regions. |
