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 is the first of the female Duggar children to be engaged; her older brother Josh is married with three children of his own. For Jill, being the first of her sisters to get married is really exciting, but also bittersweet as she'll have to move out of her parents' home in Arkansas.
