Answer 1

ANSWER :

7) The spleen is located in the left upper hypochondriac region of the abdomen, perform some vital functions such as filters old and worn out RBCs (red blood cells), since it's also a lymphatic organs hence becomes a part of immune system and their lymphocytes fight with the foreign antigens. Hence option (c) is the correct answer.

8) Functions of the lymphatic system include transport of excess interstitial fluid to the blood vascular system via specific lymphatic vessels. Hence option (a) is the correct answer.

9) T-cells or lymphocytes are specific type of immune cells in adaptive immune system, that are mainly of three types; Cytotoxic T-cells, Helper T-cells, and Suppresser T-cells, and each of them functions specifically. Hence option (a) is the not the correct answer.

10) There are several lymph nodes are found in the body, where those found in the groin area are called as inguinal lymph nodes.

11) The inflammatory mechanism is the response of innate immune system of the body, that prevents the spread of the pathogens to the nearby tissues.
