What is meant by double circulation and explain its importance from Chapter 18 of NCERT Solutions for Class 11 Biology? <\/strong><\/p>\n<p><span data-contrast=\"none\">The term &#8220;double circulation&#8221; refers to the fact that blood circulates twice in the heart. Double circulation is feasible because the heart is divided into four segments. This procedure aids in the detection and prevention of deoxygenated and oxygenated blood mixing. In this mechanism, oxygen is efficiently utilized. Students are encouraged to obtain the NCERT Solutions from our website to better comprehend this idea. These solutions are tailored to the CBSE Syllabus and Guidelines for the second term in order to enable students to master the term \u2013 II exam without anxiety.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559739&quot;:460,&quot;335559740&quot;:276}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:276}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:276}\"> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subject specialists have created NCERT Solutions for Class 11 Biology Chapter 18 Body Fluids and Circulation, which includes thorough solutions [&hellip;]<\/p>\n","protected":false},"author":7,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_yoast_wpseo_focuskw":"Free Solutions for Class 11 Biology Chapter\u00a018","_yoast_wpseo_title":"","_yoast_wpseo_metadesc":"Download Free PDF of NCERT Solutions for Class 11 Biology Chapter\u00a018 - Body Fluids and Circulation solved by Expert Teachers as per NCERT (CBSE) textbook guidelines.
