Q. No.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
Exchange of nutrients and gases between the blood and the cells always occurs:
1. by active transport
2. with the help of transport carrier proteins
3. at the arterial end of the capillary network
4. through the interstitial fluid
The nodal musculature of the heart has the capability to generate impulse:
| 1. | on stimulation by the sympathetic division of the autonomic nervous system |
| 2. | on stimulation by the parasympathetic division of the autonomic nervous system |
| 3. | on stimulation by the somatic neural division of the peripheral nervous system |
| 4. | without any external stimulus |

The functions of the lymphatic system do not include:
| 1. | The removal of interstitial fluid from tissues |
| 2. | Transport of factors needed for coagulation of blood |
| 3. | transport of nutrients and hormones |
| 4. | Absorption and transport of end products of fat digestion |
The activities of the human heart can be regulated through the autonomic nervous system by a special neural center located in:
| 1. | Medulla oblongata | 2. | Hypothalamus |
| 3. | Mid brain | 4. | Cerebrum |
To activate coagulation at the site of injury, certain factors that play an important role in coagulation, can be released by:
| 1. | Platelets and damaged tissue |
| 2. | Basophils and mast cells |
| 3. | Wall of the damaged vessel and basophils |
| 4. | Platelets and mast cells |

| Column I | Column II | ||
| A. | Mitral valve | a. | Allows blood flow from left atrium to left ventricle |
| B. | Papillary muscles | b. | Does not allow back opening of AV valves during ventricular systole |
| C. | AV node | c. | Ensure all chambers do not contract simultaneously |
| D. | Fibrous band between atrial and ventricular muscle mass | d. | Ensures atria contract before ventricles |

The first heart sound is heard during:
| 1. | beginning of ventricular systole |
| 2. | end of ventricular systole |
| 3. | atrial systole |
| 4. | ventricular ejection |
