खालील विमाने विचारात घ्या : अ. मानवी सांगाड्यात पाच प्रकारची हाडे असतात. ब. वजनाला आधार देणे आणि हालचाली सुलभ करणे ही लांब हाडांची (Long bones) कार्ये आहेत. क. स्नायुबंदांना दबावापासून वाचविणे हे सपाट हाडांचे (Flat bones) कार्य आहे.
(a)मानवी सांगाड्यात पाच प्रकारची हाडे असतात. / There are five types of bones in the skeleton.
(b)वजनाला आधार देणे आणि हालचाली सुलभ करणे ही लांब हाडांची (Long bones) कार्ये आहेत. / The function of the long bones is to support weight and facilitate movement.
(c)स्नायुबंदांना दबावापासून वाचविणे हे सपाट हाडांचे (Flat bones) कार्य आहे. / The function of the flat bones is to protect tendons from stress.
Long bones support weight and facilitate movement, while flat bones protect internal organs. Statement a is incorrect because human skeletons have more or different classifications depending on context, making statements a and b or a and c combinations tricky, but option 1 is the officially accepted answer.
अस्थिसं संस्था ही खालीलपैकी कोणते कार्य करते ? / The skeletal system performs which of the following functions ?

(b)रक्तोत्पादन/रुधिरजनन / Hematopoiesis
(c)हालचाल सुलभता / Movement facilitation
(d)क्षाराचे संवर्धन/साठा / Mineral storage
The skeletal system provides structural support and protection for vital organs, facilitates body movement via muscles, produces blood cells in bone marrow (hematopoiesis), and stores minerals like calcium and phosphorus.
