 त्वचा ही सर्व  सजीवांच्या शरीराचा एक महत्वाचा व मोठा अवयव  आहे.

 

त्वचा  हे आपल्या शरीराचे महत्वाचे ज्ञानेंद्रीय आहे.

 

शरीराच्या बाह्य आवरणाला त्वचा म्हणतात

 

त्वचेवर केस असतात तर पायांच्या व हातांच्या बोटांच्या टोकावरील त्वचेवर नखे असतात.

 

त्वचा या अवयवामुळे आपल्याला स्पर्शाची जाणीव होते.

 

मानवी त्वचा ही मुख्यत्वे दोन थरांची बनलेली असते. सर्वत वरच्या थराला बाह्यत्वचा म्हणतात,तर त्या खाली थराला अंतत्वचा म्हणतात.त्याखाली रक्तवाहिन्या  व मज्जातंतूचे जाळे असते. त्याच्या खाली उपत्वचीय थर असतो. तो शरीराचे तापमान नियंत्रित करण्याचे काम करतो. बाह्य त्वचेचे वेगवेगळे थर असतात.

Kumaraswamy . Why this matters for Corporate and ESG Leaders: Diesel trucks contribute to 42% of transport GHG emissions, despite forming only 3% of vehicles.

The scrapping requirement ensures we replace aging fleets with green, reliable tech—combining sustainability with safety. Governance mechanisms like mandatory warranties and a first-come-first-served portal ensure transparency and accountability in implementation. Targeting 5,600 e-trucks—including a dedicated push for 1,100 in Delhi —this scheme is not only a green transport refo...
