organ development

Organ development, or organogenesis, is the process by which different organs form in the body during early development. It begins with a fertilized egg dividing into many cells, which then differentiate into specific types of tissues. These tissues organize into distinct structures that mature into functional organs like the heart, lungs, and kidneys. Development involves complex signaling and genetic instructions that guide cells to grow, move, and connect properly. This coordinated process ensures organs develop in the right place, size, and timing, enabling the embryo's body to function effectively after birth.
