A lymphatic organ that helps develop the immune system is the thymus gland. The main function of this soft, roughly triangular organ is training and development of T-lymphocytes or T cells, an extremely important type of white blood cell which defend the body from potentially deadly pathogens such as bacteria, viruses, and fungi. Correct answer: B
☄ Answer :

↦ Human health , population and environment are interelated on the basis of science and technological aspects developed by human beings. Health is broadly studied in medical science and many scientific achievements affect human health in positive as well as negative ways. Some inventions like x-ray , ultrasonography , computerized tomography ( CT ) scan and various other scientific technologies are widely used in diagnosis and treatment of different diseases. These new technologies are useful in tackling human diseases and health hazards. But the use of some technologies is harmful to human health and the environment as well. Experimentation of nuclear power , development of different weapons , production of pollutants etc can be taken as some of the adverse effects of science and technology on health and the environment.
Some of scientific technologies are useful in the conservation of the environment. Identification not environmental problems and evaluation of the environmental status have been easier due to the development of technologies. In this way , health , population and environment are interrelated on the basis of science and technological aspect.
Invention and experimentation not some science and technological objects sometimes cause massive destruction of people and environment. Nuclear bomb explosion by USA at Hiroshima ( on 6th August 1965 ) and Nagasaki ( on 9th August 1945 ) in Japan are eminent examples of brutal destructive effects caused by technological development on human and the earth. The radioactive effects of the explosion are still inhibiting natural development of life at the affected areas even after several decades.
Science and technological aspects have both positive and negative impacts on human health , population and environment. Hence , they are closely related with each other.

In the United States, the Food and Drug Administration's regulations prohibit any use of hormones in pork and poultry, so those industries do not use artificial or added hormones in the production process. Therefore, all pork and poultry is eligible to be labeled with “Raised without Hormones”.
