Question 21

knonw as red blood cells. make up 40% on the blood. contain a value known as hematocrit

Answer 21

erythrocytes

Question 22

value within the erythrocyte that makes up 99.9% of all formed elements

Answer 22

hematocrit

Question 23

structure of the erythrocytes

Answer 23

biconcave disc

Question 24

what is the significance of the erythrocyte structure

Answer 24

allows passage through capillaries– due to rouleaux

Question 25

rouleaux allows for

Answer 25

erythrocytes to be squish and squeeze through capillaries– they are flexible
