In determining hematocrit, if the length of erythrocytes in the capillary tube is 45 millimiters and the length of total blood is 95, what is the hematocrit?

47%

Explanation:

The hematocrit measures the volume of erythrocytes compared to the total blood volume. It's calculated as the ratio of the length of erythrocytes in the capillary tube to the length of total blood. It's expressed in percentage, so we have to multiply the ratio by 100%.

 x 100 %

Hematocrit = 47%

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
