World of Biology on Instagram: "The evolution of the human heart! - We created this video showing the development of the human heart, starting from day 20, when the first primitive tube begins to beat. Over the following weeks, the heart loops, partitions, and rapidly grows more complex. By around day 70 (week 10), it has reached its fully developed four-chambered form, complete with visible blood vessels. This visualization highlights each stage leading to the final structure showing the aorta,

Biology on Instagram: "Prenatal development. The process by which a human life forms and grows inside the womb, unfolding in three main stages. The germinal stage (weeks 1–2) begins with fertilization, as the zygote travels to the uterus and implants itself. During the embryonic stage (weeks 3–8), the major organs and body structures begin to form—such as the brain, heart, and spinal cord—while the heart starts beating and facial features emerge. Finally, the fetal stage (week 9 to birth) is mar

Biology on Instagram: "Mitosis 🧬 The process of cell division where one parent cell creates two genetically identical daughter cells. The phases of mitosis are Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. These stages are followed by Cytokinesis, the physical splitting of the cell into two new cells. The stages of mitosis occur in a specific order to ensure proper , which is on the centromere of each chromosome. Why is it important? Mitosis is essential for growth, repair of dama

World of Biology on Instagram: "When Nature Needs a Helping Hand . . In rare cases, when the placenta does not detach naturally after childbirth, doctors may perform manual removal of the placenta. This involves carefully inserting a gloved hand into the uterus under anesthesia to separate and extract the placenta. The procedure helps prevent heavy bleeding (postpartum hemorrhage) and ensures no placental tissue is left behind, protecting the mother’s health. • • Video credit 📸 - Body talks 28
