Which of the following are the requirements for blood clotting? Select all that apply.
|
Presence of platelets |
||
|
Von Willebrand Factor |
||
|
Thrombolysis |
||
|
Clotting factors |
Ans) Presence of platelets, Von Willebrand Factor, Clotting factors.
Explaination:
- Von Willebrand disease (VWD) is a genetic disorder caused by missing or defective von Willebrand factor (VWF), a clotting protein. VWF binds factor VIII, a key clotting protein, and platelets in blood vessel walls, which help form a platelet plug during the clotting process.
- Cells such as platelets & clotting factors help in clotting process.
- Thrombosis is a formation of blood clot but thrombolysis is dissolving of blood clots

Which of these lists the components of the conduction system in the heart in the correct order, from slowest to fastest? Select one: a. Purkinje fibers; AV node; SA node b. SA...
The primary role of platelets is to control blood clotting. When they encounter the exposed basement membrane (collagen fibers) of a damaged blood vessel or a newly forming fibrin clot, they change their shape from round to spiky and stick to the damaged area. At the same time, they begin to secrete serotonin and ATP, which accelerate similar changes in newly arriving platelets, leading to the rapid formation of a clot. The platelet response is regulated by protein phosphorylation. Significantly,...
Which of the following regarding platelet activation in homeostasis and thrombosis is not correct? a. Platelets adhere directly to subendothelial collagen via GPIa-IIa and GPVI, while binding of GPIb-IX-V is mediated via von Willebrand factor. b. The aggregating agent thromboxane A2 is formed from arachindonic acid liberated from platelet membrane phospholipids by the action of phospholipase A2. c. The aggregating agent ADP is released from the dense granules if activated platelets. d. The ADP receptors, the thromboxane A2 receptor, the...
Discuss the process of blood coagulation and clotting. What is the mechanism by which blood clots dissolve? Describe how antiplatelet agents, anticoagulants, low-molecular-weight heparins, thrombolytic agents, antihemophilic agents, and hemostatic agents affect blood clotting.

1. Which of the following information is accurate regarding hypertension? (Select all that apply.) a. It is an increase in blood pressure that is sustained over a long period of time b. It is a decrease in blood pressure that is sustained over a long period of time c. Increased resistance to arteries influence blood flow and can lead to hypertension d.

Question 35 Which statements are correct regarding platelets? Select all that apply Platelet formation is stimulated by the hormone thrombopoietin. O Platelets increase in the bone marrow. □ Platelets have a lifespan of less than 7 days. Platelets spend one-third of their lives in the spleen. Platelet adhesion results in the activation of the glycoprotein.
