Answer 26

clotting

Question 27

buffy coat

Answer 27

concentration of all wbcs and platelets in a sample of blood

Question 28

hemostasis

Answer 28

- after a blood vessel is damaged, we have a vascular spasm, where blood vessels constrict to reduce blood loss - platelets plug formation occurs where platelets clump up and create a seal - in blood coagulation, a mesh forms around the plug and secure plug to the site, thus making the rbcs and platelets are trapped at the site creating a clot
