Answer 6

fibrin

Question 7

Released by platelets along with calcium, the substance is necessary for secondary homeostasis.

Answer 7

Answer 8

folic acid.

Question 9

Under normal circumstances, this substance and prostacyclin block platelets from adhering to the cell membrane; it is also secreted by the endothelial cells

Answer 9

nitric oxide

Question 10

Under normal circumstances , this substance and nitric oxide block platelets from adhering to the cell membrane; its also secreted by the endothelial cells

Answer 10

prostacyclin

Question 11

A neurotransmitter released by platelets in the clotting process, that acts as a vasodilator

Answer 11

serotonin

Question 12

This enzyme mediates conversions of fibrinogen to fibrin through activation of the coagulation cascade. This process represents secondary hemostasis

Answer 12

thrombin

Question 14

The most common (70-80%) and mildest form con willebrand disease. It follows an autosomal dominant inheritance pattern. The level of Von willebrand factor in the blood is reduced. It is often very mild and most cases go undiagnosed.

Answer 14

Type 1 von willebrand disease.

Question 15

This form of von willebrand disease that occurs in 15-20% of cases. It can be either autosomal dominant or recessive and four subtypes exist. The building blocks that make up the von willebrand factor are smaller than usual and break down easily . Bleeding is usually moderate or severe

Answer 15

Type 2 von willebrand disease

Question 16

This form of von willebrand disease follows and autosomal recessive inheritance pattern. Severe bleeding problems are seen with this type due to lack of measurable von willebrand factor and factor 8. It is the rarest form.

Answer 16
