where is the thymus located in your body
Thymus In children, the thymus is pinkish-gray, soft, and lobulated on its surfaces. At birth it is about 4–6 cm long, 2.5–5 cm wide, and about 1 cm thick.[1] It is made up of two lobes that meet in upper midline, that stretch from below the thyroid in the neck to as low as the cartilage of the fourth rib.[1] It lies beneath the sternum, rests on the pericardium, and is separated from the aortic arch and great vessels by a layer of fascia. The left brachiocephalic vein may even be embedded within the thymus.[1] In the neck, it lies on the front and sides of the trachea, behind the sternohyoidei and sternothyreoidei.[1]
Jejunum The jejunum (/dʒɪˈdʒuːnəm/[2][3]) is the second part of the small intestine in humans and most higher vertebrates, including mammals, reptiles, and birds.
Thorax In humans and other hominids, the thorax is the chest region of the body between the neck and the abdomen, along with its internal organs and other contents. It is mostly protected and supported by the rib cage, spine, and shoulder girdle.
Vein Veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small.
