The appendix, one of the most misunderstood organs, is responsible for initiating many defensive actions in the body. Its connection to the heart is through prompting the heart to speed up when blood flow is sluggish and to slow down when wounds compromise life force (because too much blood is being lost to sustain life).
The appendix and the heart generally function independently of one another. Their tasks are complementary, yet separate. Only when blood flow is compromised does the appendix initiate heart-related activity.
For people whose appendixes have been removed, these activities are not transferred to other organs or systems in the body (unlike other healing activities that are transferred, as mentioned in the post “How does the body heal when the appendix is removed?”).
