Vedclass · Answer

(D) The Thymus gland is a lobular structure located between the lungs behind the sternum on the ventral side of the aorta,which is in the upper part of the thorax ($i$ is correct).It is a bilobed structure,not four-lobed ($ii$ is incorrect).It is a prominent gland at birth but gradually atrophies with age,meaning it does not remain active throughout life ($iii$ is incorrect).Due to its atrophy in adults,it is often referred to as a temporary gland ($iv$ is correct).The Thymus plays a major role in the development of the immune system by secreting thymosins,which promote the differentiation of $T$-lymphocytes,providing cell-mediated immunity,not humoral immunity ($v$ is incorrect).Therefore,only statements $i$ and $iv$ are correct. However,based on the provided options,the most appropriate choice reflecting the anatomical location and the temporary nature of the gland is $D$.
