Question

note on composition of blood​

Answer 1

Answer:

Explanation:

Blood is a suspension of blood elements (erythrocytes, leukocytes, and platelets) in blood plasma. Blood elements can be separated from blood plasma using centrifugal force. Figure shows that the most descended are erythrocytes – the volume of erythrocytes in a sample of blood is called the hematocrit. Hematocrit values differ depending on sex – in men the values range about 44 ± 5 % of blood volume and in women about 39 ± 4 % of blood volume. Above the erythrocyte layer is found the white non-transparent layer composed of leukocytes and thrombocytes. This layer is called buffy coat (forms about 1 % of blood volume).
