To put a condom on, you will also want to move the foreskin gently back some while you roll the condom on, so that it can move comfortably inside the condom. If and when your foreskin moves inside a vagina, a mouth, a rectum, a hand -- whatever it is inside of -- that's when more of the tip of your penis will be exposed.
Thymus Gland. The thymus gland, despite containing glandular tissue and producing several hormones, is much more closely associated with the immune system than with the endocrine system. The thymus serves a vital role in the training and development of T-lymphocytes or T cells, an extremely important type of white blood cell.
Lymphocytes are concentrated in the lymph nodes. The spleen and the thymus are also lymphoid organs of the immune system. The tonsils are lymphoid organs that are also associated with the digestive system. Lymphoid tissues contain lymphocytes, and also contain other types of cells for support.he lymphatic system is part of the circulatory system and a vital part of the immune system, comprising a network of lymphatic vessels that carry a clear fluid called lymph (from Latin lympha meaning water) directionally towards the heart.
