Circulatory System 2 Flashcards
What are white blood cells
Involved in immune system, warriors, attack bacteria u
What are platelets
Involved in blood clotting, stop bleeding
What are red blood cells
Carry oxygen
What 3 types of suspended cells are contained in plasma
Red blood cells (erythrocytes)
White blood cells (leukocytes)
Platelets
What percentage of water does plasma contain and what are the other bits
90% dissolved substances, mostly protein
What is the percentage is plasma of total blood volume
55%
How much are red blood cells of total blood volume? What is the percentage of cells in blood
45% and 99%
What is hemoglobin ( carried by red blood cells)
An iron containing proteins that binds about 97% of all oxygen in body
Is oxygen soluble in water
Not very - it needs a carrier like hemoglobin to travel around the bloodstream
How does the shape - name it - affect oxygen exchange
Discotic - doughnut with no hole - increases surface area
Type A
Protein A and antibodies to protein B receive A, AB, d
Type B
Protein B and antibodies to protein B receive B, AB,D
Type AB
Both proteins so a universal receptor because of its lack of antibodies will not attack - A, B, AB, O
Type O
No proteins and both antibodies - universal donor - because it’s lack of proteins will not be attacked
What do white blood cells do
Defend against external organisms, clean up dead cells and tissue debris that could accumulate and lead to damage
