Exam 2 - Hematologic Concepts

Question 1

erythrocytes

Answer 1

• red blood cell
• their purpose is to transport O2 to the tissues using hemoglobin

Question 2

reticulocytes

Answer 2

• immature RBCs
• normal count is 1% of the total RBC count

Question 3

hemoglobin

Answer 3

• oxygen carrying protein
• contains iron and oxygen molecules

Question 4

normal hemoglobin for men

Answer 4

14-18

Question 5

normal hemoglobin for women

Answer 5

12-16

Question 6

erythropoiesis

Answer 6

• RBC production
• kidney senses hypoxia and releases the hormones erythropoietin, which stimulates RBC production in the bone marrow

Question 7

erythrocytes

Answer 7

• made up of protein and hemoglobin

Question 8

pulmonary gas exchange

Answer 8

• external respiration
• O2 is inhaled in from the atmosphere across the alveolar-capillary membrane
• O2 diffuses from the alveoli into the arterial pulmonary capillaries

Question 9

capillary gas exchange

Answer 9

• internal respiration
• when arterial blood reaches the tissues via the capillaries, gas exchange occurs again
• O2 is exchanged between the capillaries and the tissue cells that lie adjacent to the capillaries
