When two non-compatible blood types are mixed together, agglutination occurs. This is the clumping of red blood cells due to the interaction between antibodies in the recipient's plasma and antigens on the donor's red blood cells. This can lead to serious complications, including hemolysis and immune reactions, which disrupt normal blood flow and can damage organs. Other processes like platelet plug formation and coagulation may also be affected, but agglutination is the primary immediate response.
Yes, coagulation begins with vasoconstriction and the formation of a platelet plug at the site of injury. This is followed by activation of clotting factors leading to the formation of a stable fibrin clot to stop bleeding.

The four stages of hemostasis are vasoconstriction, formation of a platelet plug, blood clotting (coagulation), and clot retraction. These stages work together to stop bleeding when a blood vessel is injured.
The process of stopping bleeding is called hemostasis. It involves the constriction or narrowing of blood vessels, formation of a platelet plug to temporarily block the bleeding, and activation of the coagulation cascade to form a stable blood clot. This process is crucial for maintaining normal blood circulation and preventing excessive blood loss.
Thrombopoietin is the hormone that regulates platelet formation. It is produced primarily in the liver and kidneys and acts on bone marrow to stimulate the production of platelets.

The four stages of hemostasis are vasoconstriction, formation of a platelet plug, blood clotting (coagulation), and clot retraction. These stages work together to stop bleeding when a blood vessel is injured.
The process that causes bleeding to stop is called hemostasis. It involves three main steps: vascular spasm (constriction of blood vessels), platelet plug formation (where platelets adhere to the injury site and aggregate), and coagulation (the formation of a fibrin clot to stabilize the platelet plug). These mechanisms work together to prevent excessive blood loss and promote healing.
Hemostasis is when the blood is outside the body by way of an injury. The vessels constrict and cause clotting to stop the bleeding.

It involves the constriction or narrowing of blood vessels, formation of a platelet plug to temporarily block the bleeding, and activation of the coagulation cascade to form a stable blood clot.

Thrombopoietin is the hormone that regulates platelet formation. It is produced primarily in the liver and kidneys and acts on bone marrow to stimulate the production of platelets.
Because coagulation requires a combination of platelet activation, activation of coagulation cascade (by trauma or damaged endothelial walls), and in predisposed individuals, abnormalities in regulator proteins such as protein C and anti-thrombin
