Chapter 11 Pt. 2 (Final Exam Pt. 2) Flashcards
What are blood types?
how blood is categorized according to the presence of absence of certain molecules (mostly proteins) on the surface of a person’s red blood cells
What is agglutinate?
clumping of blood
What type of antigens are on type A blood? And what shape are they?
A antigens (which are circular)
What type of antigens are on type B blood? And what shape are they?
B antigens (which are cubical)
What type of antigens are on type AB blood? And what shape are they?
A and B antigens (both circular and cubical)

What is RH factor?
it’s presence or absence is a significant component of blood type
What does the name Rh come from?
the beginning of the name of the rhesus monkey, in which an Rh antigen was first discovered
What is hemolytic disease of the newborn?
a condition that is a result of anti-Rh anti-bodies destroying the fetus’s red blood cells causing the child to be stillborn or anemic at birth
What is a platelet plug?
is formed when platelets cling to cables of collagen, a protein fiber on the torn blood vessel surface
The process of clot formation:
(1)
(2) clotting factors convert an inactive blood protein to prothrombin activator
(3) prothrombin activator converts prothrombin to thrombin
(4) thrombin converts fibrinogen to fibrin
(5) the fibrin network traps red blood cells and platelets, forming a blood clot
(1) injured cells in the walls of the vessels and platelets release clotting factors

Without vitamin ___, clotting does not occur
K
What are our 2 sources of Vitamin K?
(1) diet
(2) bacteria living in our intestines
What is Hemophilia?
an inherited condition in which the affected person bleeds excessively owing to a fault in one of the genes involved in producing clotting factors
What is the difference between thrombus and embolus?
thrombus- a blood clot lodged in an unbroken blood vessel
embolus- a blood clot that drifts through the circulatory system
clots are normally dissolved by an enzyme called ________
plasmin
_______ is formed from an inactive protein, plasminogen
plasmin
