Answer 1

1.E.all the above .lymph nodes filter lymph before returning fluid into blood , contains specialized cells for immune defense , are divided into compartments , have inner medulla and outer cortex.

2.B.thyroid is not a lyphoid organ. Lymphoid organs include spleen , thymus , tonsils , lymph nodes , Peyers patches etc.

3.D . dizziness.... signs of acute inflammation includes pain , redness , heat , swelling and loss of function . Dizziness is a sensation of spinning around .

B.B cells .. antibodies are secreted by B cells .

4.D all the above

5.E .digestive and respiratory ...it's serves in function of swallowing and pathway for movement of food.

6.E.all the above... respiratory system has all the given functions.

7. C.epiglottis , it's covers the opening of larynx.

8.A . diffusion....gases exchange in alveoli occurs by diffusion

9.A.air moves into the lungs ... inspiration occurs when intrapulmonary pressure is less than atmospheric pressure.

10 E.none of the above. Alveoli are surrounded by tiny blood vessels called capillaries.

11. E none of the above ...it is surrounded by c shaped cartilaginous rings , it is rigid , it is found anterior to esophagus.

12.D. all the above ..nasal conchae increases the surface area and provides the above functions.

13.A.ileum ,...longest portion of small intestine is ileum.

14.D. jejunum....bulk of chemical digestion and nutrient absorption occurs in jejunum.

15.D.microvilli ...interior of small intestine have finger like projections called microvilli.

16.D.longer than small intestine...except this remaining are true ..

17.B. cystic duct ...bile enters duodenum through common bile duct which is formed by merging of cystic and common hepatic duct.

18.D.ileum .. Peyers patches are found in ileum region

19.E. all the above...but majority of fat digestion occurs in the small intestine by pancreatic juices...hence when majority of absorption is asked answer becomes small intestine.
