Question 7

Total volumes of blood in average adult is

Answer 7

6 Liter, or 7% to 8% of the body weight

Question 8

Circulating blood is divided as fallow:

Answer 8

45% red, white blood cell, platelets
55% plasma
Plasma = (55% of total blood)
Buffy coat = leukocytes & platelets ( 1% of total blood)
Erythrocytes( 45% of total blood)

Question 9

Buffy coat

Answer 9

Leukocytes & platelets

Question 10

Erythrocytes

Answer 10

Red blood cell

Question 11

Plasma referring the whole element of whole blood that is suspend in it

Answer 11

90% the composition plasma is water
10% is soil able vial chemical protein, carbon hydrate, vitamin, hormone, enzyme, salts, sugar, fats,

Plasma is main contain of blood and consist mostly of water, with proteins,ions, nutrients, and wastes mixed in.
It has gases

Question 12

Hematopoiesis mean

Answer 12

Question 13

Hematopoiesis begin In

Answer 13

Question 16

Oxygen is transported in The chemical combination with

Answer 16

in The chemical combination with hemoglobin (HB)

Question 17

The concentration of Hb in the blood is a measurement of capacity

Answer 17

to carry oxygen

Question 18

To combine with and transport oxygen, hb molecuolesd must have certain combination of

Answer 18

Heme ( contains iron) and globin.

Question 19

The red blood cell(RBC) begin as a nucleated cell within the

Answer 19

Bone marrow

Question 20

As the cell matures in the bone marrow, its diameter

Answer 20

Decreases, and the nucleus becomes denser and smaller, and is finally released from the cell (extruded) to become a biconcave disk.

Question 21

RBC have a total life span of about

Answer 21

120 days

Question 22

Bone marrow release new cells into the

Answer 22

Circulatory system every day

Question 23

RBC formation and destructive process

Answer 23

New red cells are formed in the boned marrow
Cells released into the circulating blood.
As the cells wear out, the reticuloendothelial system breaks them down.
Protein from these cells goes into protein storage pool, which can be used again in bone marrow to produce new cells.
Irons from these cells is recycled into an iron storage pool to be reused in the bone marrow to produce new cells.
Waste products are excreted in the form of bile in urine and feces.
