Can a Deceased Person’s Soul Live On in the Recipient of His Heart?

Questions about whether a deceased person’s soul can live on in the recipient of his heart, whether 1 Corinthians 15:44 confirms that babies in the womb have a soul, why bodies are important, how to explain the soul to a child, and how the spirit relates to the soul.   Could the stories about recipients of donated hearts acting like the donors mean that if a person dies and his heart is donated to someone else, his soul lives on in the recipient? Does 1 Corinthians 15:44 confirm that babies in the womb have a soul when it says that if there is a natural body, there is also a spiritual body? In light of your article “The Invisible Man,” why are bodies important? How would you explain the existence of a soul to a child or someone who has never heard of this idea? How does a person’s spirit relate to his soul?
