What are the components of the cardiovascular system?
Blood, blood vessels & heart
1 of 15
What are the components of the blood?
Erythrocytes, Leukocytes, Platelets, Plasma
2 of 15
What are the components of blood vessels?
Arteries, arterioles, capillaries, venules & veins.
3 of 15
What are the principal blood types?
A,B,AB & O
4 of 15
What is responsible for the ABO types?
2 antigens and 2 antibodies
5 of 15
Who discovered the blood groups?
Karl Landsteiner
6 of 15
How can ABO blood types be determined?
Using anti-A and anti-B antibodies, whether or not agglutination occurs indicates ABO type. If blood is agglutinated by anti-A but not by anti-B, then only antigen A is present, so blood type A.
7 of 15
How are blood types inherited?
Through genes on chromosome 9
8 of 15
People with type A blood with produce which antibodies?
Anti-B antibodies.
9 of 15
What happens if B type blood is transfused into the system of someone with type A blood?
Their anti-B antibodies will recognised it as foreign and agglutinate the introduced red blood cells, resulting in cell death.
10 of 15
What is unique about type O blood?
It is a universal donor as it does not produce ABO antigens, so will not be rejected when given to others.
11 of 15
Can type O blood types receive all types of blood?
No, they can only receive type O blood themselves?
12 of 15
What is unique about type AB blood?
It is a universal receiver - they do not make any ABO antibodies and are universal receivers for transfusions, but their blood cannot be donated because they produce both antigens.
13 of 15
What is the path of blood flow?
DeOx blood enters RA, enters RV, enters pulmonary artery, oxygenation of blood in lungs, blood enters LA, enters LV via pulmonary veins, Ox blood pumped from LV to aorta. Oxygen leaves blood and enters tissues.
