Webb1 BIOL 2222: BLOOD [CHAP.17/SECT.6] Normally, blood flows smoothly past the intact blood vessel lining (endothelium). But if a blood vessel wall breaks, a whole series of reactions is set in motion to accomplish hemostasis, which stops the bleeding (stasis=halting). Without this plug-the-hole defensive reaction, we would quickly bleed … WebbHemostatic forceps were used to carry out a thoracotomy on the left fourth intercostal area of the rats, and a thoracic retractor was used to expand the ribs and expose the left heart ventricle. The epicardium was opened up to find the left anterior descending (LAD) artery, and the blood vessel was ligated proximal to the LAD using a 6/0 ene suture to avoid the …

WebbWhat are the 4 steps of hemostasis? The mechanism of hemostasis can divide into four stages. 1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug." 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.

WebbThe development of a blood clot strengthens the platelet plug but isolates the platelet plug from the general circulation. Step 3: Coagulation. The formation of a blood clot is known as coagulation. The coagulation phase requires many biochemicals known as clotting factors or procoagulants. They are synthesized by the liver.
