This Video Include :-
Body Fluids and Circulation
[00:00:00]: The video begins with a lecture on the topic of "Body Fluids and Circulation".
[00:00:06]: It is introduced as a lecture for students preparing for the NEET 2026 and 2027 exams.
[00:00:19]: The primary focus of the lecture is narrowed down to blood coagulation.
[00:03:09]: The definition of blood coagulation is explained as the process of stopping bleeding from a cut or damaged blood vessel.
[00:03:34]: The important role of Calcium ions in the coagulation process is highlighted.
[00:04:15]: The significance of Vitamin K in blood coagulation is discussed.
[00:05:29]: The presence of the natural anticoagulant heparin, which prevents blood from clotting inside the body, is mentioned.
[00:06:19]: The use of artificial anticoagulants like EDTA and Sodium Citrate in blood banks is explained.
[00:06:55]: The video begins to detail the three-step mechanism of coagulation that occurs when a blood vessel is damaged.
[00:08:33]: The first step is detailed, where damaged tissues and platelets release thromboplastin.
[00:09:14]: The second step is described: thromboplastin, along with calcium and other factors, activates the enzyme thrombokinase.
[00:11:29]: The third step is explained: thrombokinase converts inactive prothrombin into active thrombin.
[00:12:08]: The final stage of the process is shown, where thrombin converts fibrinogen into fibrin, which forms a clot.
[00:13:51]: The video briefly touches on the dangers of a clot forming inside the body, such as a stroke or heart attack.
[00:14:11]: The condition of hemophilia, where blood fails to clot, is mentioned.
