D. Thymus
1. Located in the upper chest, behind the sternum
2. Above the heart and below the thyroid gland
E. Bone marrow
1. Found within the cavities of bones (e.g. femur, pelvis, sternum)
2. Produces and releases lymphocytes into the blood
F. Tonsils
1. Positioned at the back of the throat
2. One on each side of the throat (known as palatine tonsils)
