In 100 mL of blood, what is the expected volume of plasma?
1. | 90 mL | 2. | 10 mL |
3. | 45 mL | 4. | 55 mL |
What is the percentage of proteins in plasma?
1. | 10% | 2. | 7% |
3. | 25% | 4. | 92% |
Identify the incorrectly matched pair:
1. | Plasma protein | – | 6 to 8 % |
2. | Formed elements | – | 55% of the blood |
3. | Hemoglobin | – | 12 to 16 gm in 100 ml of blood |
4. | Platelets | – | 150000 to 350000 mm-3 |
The colloid osmotic pressure in the human blood is largely due to:
1. | electrolytes | 2. | albumin |
3. | fibrinogen | 4. | globulins |
I: | Fibrinogens are needed for clotting or coagulation of blood. |
II: | Globulins, primarily, are involved in the defense mechanisms of the body. |
III: | The albumins help in osmotic balance. |
1. | Only I | 2. | Only I and III |
3. | Only II and III | 4. | I, II and III |
Formed elements and clotting factors are removed from the blood. The remaining fluid will be called as:
1. | Plasma | 2. | Lymph |
3. | Serum | 4. | Antiserum |
A person has a complete blood count done. Which of the following would not be normal?
1. total RBC count - 5.0 million /µL
2. total WBC count – 1500 /µL
3. total platelet count - 225,000 /µL
4. hemoglobin – 14.5 g / 100 ml
I: | lack both a nucleus and mitochondria organelles. |
II: | are much more common than leukocytes in the blood. |
III: | require dietary iron and vitamin B12 for normal production. |
IV: | have a circulating life span of about twelve months. |
I: | Red blood cells in humans have a nucleus. |
II: | Blood plasma contains fibrinogen which helps in clotting. |
Component (List I) | Function (List II) | ||
A. | Plasma | 1. | Transport of oxygen and carbon dioxide |
B. | Red Blood Cells (RBCs) | 2. | Clot formation |
C. | White Blood Cells (WBCs) | 3. | Regulation of blood volume and pressure |
D. | Platelets | 4. | Defense against pathogens |
