Your baby’s circulatory system moves blood throughout her body, carrying oxygen, nutrients, and gases to her organs and tissues. Before birth, the umbilical cord acts as your baby’s circulatory system; it gathers all she needs from her mother’s placenta and then removes waste.
When the umbilical cord is cut, your baby breathes her first few breaths of air, and that starts her independent circulation. From that moment on, with each heartbeat, her circulatory system carries blood from her heart to the billions of cells in her body.
Your baby’s circulatory system depends on three body systems working together: cardiovascular (heart), pulmonary (lungs), and systemic (arteries, veins, and vessels). Her blood circulates through two loops in her body, from her heart to her lungs and back again. Her heart is the key actor, as it sorts and pumps her blood.
Good blood flow affects every organ in your baby’s body and every aspect of her health. Exercise, stretching, breathing exercises, physical connection through massage, good sleep, fresh air, and wholesome food help keep her circulatory system strong and vibrant.
Circulatory issues for babies up to three years old are rare. Therefore, there are no common childhood illnesses to list under this system.
