The endocardium is the innermost layer of tissue that lines the chambers of the heart. Its cells are embryologically and biologically similar to the endothelial cells that line blood vessels. The endocardium also provides protection to the valves and heart chambers.
In 2002, there were five sisters living in the Duggar house: Jana, then 12; Jill, 11; Jessa, 10; Jinger, 9; and Joy-Anna, 5. In March 2003, Jim Bob met with âchurch eldersâ to discuss Joshâs behavior, and they decided Josh needed to enter a treatment program.
Jill handpicked her eight bridesmaids, which included her sister-in-law Anna, 25, and even her only niece Mackynzie, 5, as a flower girl. Derick, 26, used three Duggar boys as groomsmen, John-David, 25, Joseph, 20, and Jackson, 11. Derick even had little Michael, 3, (Josh and Anna's eldest son) serve as ring bearer. But Josh Duggar was not among them. Fans of the hit show may have missed the biggest sign of discord when Jill Duggar married Derick Dillard on June 21, 2014 at the Cross Church in Springdale Arkansas in front of almost 1,000 guests.
