Ans 10:

Class : Class 8
i think heart is correct answer. please elaborate, how come kidney is right answer a

Ans 11:

Class : Class 6
I thinks it should be heart. As lungs are connected with the heart not kidney.

Ans 12:

Class : Class 6
lungs and spinal cords are part of nervous system so lungs and kidney are part of excretory system(lungs dispose co2 from body)

Ans 13:

Class : Class 5
Answer is D because both lungs n kidney are in Exetery system

Ans 14:

Class : Class 8
D because spinal cord helps brain to control the body.

Ans 15:

Class : Class 3
I think both kidneys and hearth are correct. beacause lungs are in respiratory,curculatory and excretory system as they help us to brathe ,make pure blood and also the blood goes from hearth then lungs and then all parts. Plese tell how hearth is wrone.

Ans 16:

Class : Class 5
I think it should be heart not kidney

Ans 17:

Class : Class 3
I think option a is also correct with option d as lungs are in curcularury system system too as the blood first goes to the lungs after the heath and then the body. Lungs also filter air and help us breathe so they are in excretory and resperatory system too. Plese tell how option a hearth is wrong .

Ans 18:

Class : Class 4
It will be kidney because lungs give out carbon dioxide as waste.Heart is the wrong answer........
