મોટાભાગના પ્રાણીઓમાં હૃદય એક સ્નાયુબદ્ધ અંગ છે. આ અંગ રુધિરાભિસરણ તંત્રની રક્તવાહિનીઓ દ્વારા લોહીને પમ્પ કરે છે. પમ્પ થયેલું લોહી શરીરમાં ઓક્સિજન અને પોષક તત્વોનું વહન કરે છે, જ્યારે કાર્બન ડાયોક્સાઇડ જેવા મેટાબોલિક કચરાને ફેફસામાં લઈ જાય છે. મનુષ્યોમાં, હૃદય લગભગ બંધ મુઠ્ઠી જેટલું હોય છે અને તે ફેફસાંની વચ્ચે, છાતીના મધ્ય ભાગમાં સ્થિત હોય છે.<br /><br />https://dai.ly/x8fp4g3<br />https://dai.ly/x8fp4g4<br />https://dai.ly/x8fp4g5<br /><br />https://www.youtube.com/channel/UCtfsUrX6JhKxSdtD3U04Xvw<br />https://www.youtube.com/watch?v=9v3MK6oTOeA&t=1s<br />https://www.youtube.com/watch?v=vxa6o_wrWnY<br />https://www.youtube.com/watch?v=T7mMcEYNKyQ<br />https://www.youtube.com/watch?v=BrakSGmQZB8&t=9s<br /><br />#Contact us<br /><br />Mobile : +917016525813<br />Whatsapp & Telegram : +919409077371<br />Email : hemangjoshi37a@gmail.com<br />Place a custom order on hjLabs.in : https://hjLabs.in<br />Please contribute your suggestions and corrections to support our efforts.<br />Thank you.<br />Buy us a coffee for $5 on PayPal ?<br />[](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=5JXC8VRCSUZWJ)<br /><br />----------------------------------------------------------------------------------------<br /><br />## Checkout Our Other Repositories:<br />https://github.com/hemangjoshi37a/pyPortMan<br />https://github.com/hemangjoshi37a/transformers_stock_prediction<br />https://github.com/hemangjoshi37a/TrendMaster<br />https://github.com/hemangjoshi37a/hjAlgos_notebooks<br />https://github.com/hemangjoshi37a/AutoCut<br />https://github.com/hemangjoshi37a/My_Projects<br />https://github.com/hemangjoshi37a/my_Arduino<br /><br /><br />## Checkout Our Other Products:<br />https://hjlabs.in/product/wifi-iot-led-display<br />https://hjlabs.in/product/swiboard-wifi-switch-board-iot-device<br />https://hjlabs.in/product/electric-bicycle<br />https://hjlabs.in/product/product-3d-design-with-solidworks/<br />https://hjlabs.in/product/automatic-wire-cutter-machine/<br />https://hjlabs.in/product/custom-algotrading-software-for-zerodha-and-angel-w-source-code/<br />https://play.google.com/store/apps/details?id=in.hjlabs.swiboard<br /><br />## Some Cool Arduino and ESP8266 (or NodeMCU) IoT projects:<br />https://github.com/hemangjoshi37a/my_Arduino/tree/master/IoT_LED_over_ESP8266_NodeMCU<br />https://github.com/hemangjoshi37a/my_Arduino/tree/master/ESP8266_NodeMCU_BasicOTA<br />https://github.com/hemangjoshi37a/my_Arduino/tree/master/IoT_CSV_SD<br />https://github.com/hemangjoshi37a/my_Arduino/tree/master/Honeywell_I2C_Datalogger<br />https://github.com/hemangjoshi37a/my_Arduino/tree/master/IoT_Load_Cell_using_ESP8266_NodeMC<br />https://github.com/hemangjoshi37a/my_Arduino/tree/master/IoT_SSD1306_ESP8266_NodeMCU<br /><br />## Some cool websites :<br />https://www.autoactionhub.com/<br />https://smn.hjlabs.in/<br />https://mangomuse.hjlabs.in/<br />https://aayurva.hjlabs.in/<br />https://ghcompare.hjlabs.in
