Question

Riolegy 226 Refer to pages 649 to 654 in your textbook to help you answer the following questions What is the first and most immediate response to breakage of a blood vesvel? How does this response help minimize blood loss? What stimulates thrombocytes to adhere to a broken blood vessel wall? When activated, thrombocytes respond in two different ways simultaneously, both of which increase the rate of platelet plug formation. State these two ways and platelet adhesion. deseribe how each contr/butes to further Change How Platelet Plug Formation is Heloed 2) If a platelet plug completely filled in clot necessary? the space in a broken blood vessel wall, why is formation of a blood What is meant by the clotting cascade? What type of molecule is a clotting factor? What is the stimulus for the intrinsic pathway, and where is this stimulus located? What is the stimulus for the extrinsic pathway, and where does this stimulus come from? In what kind of circumstance would both pathways be activated as the same time?

Answer 1

1. Fibrin clot formation / thrombogenesis
2. It leads to formation of clot at the point of breakage which prevents blood from leakage
3. Inflammatory cytokinesis are the key stimulants which activate the thrombogenic cycle.
4. A. Release of cytokinesis and other regulatory factors which being in more substance and input for adhesions.

B. Formation of plug, which acts as a barrier to leakage
