| 1. | Severe jaundice affecting neurons |
| 2. | Generalized edema of the body |
| 3. | Hypertension and atherosclerosis |
| 4. | Hypoxia in actively metabolizing tissues |
Which of the following cells will not contain DNA?
| 1. | An enucleated ovum |
| 2. | A megakaryocyte |
| 3. | A neuron that is permanently in G0 phase |
| 4. | A mature human RBC |
Individuals with blood group ‘O’ are called as universal donors because:
| 1. | No antigens are present on the surface of their RBC |
| 2. | Both anti-A and anti-B antibodies are present in their plasma |
| 3. | The IO allele is recessive to both IA and IB alleles |
| 4. | It is the most common blood group and hence easily available |
A treatment for haemolytic disease of the newborn [erythroblastosis fetalis] can be:
| 1. | administering anti-Rh antibodies to the mother immediately after the delivery of the first child |
| 2. | administering anti-Rh antibodies to the new born immediately after birth |
| 3. | administering anti-Rh antibodies to the mother at 16 – 20 weeks of pregnancy |
| 4. | phototherapy |
Which of the following, if introduced into the blood, will induce coagulation at the site of its introduction?
| 1. | Heparin | 2. | Prothrombin |
| 3. | Thromboplastin | 4. | Fibrinogen |
A hormone like thyroxin will be secreted by the thyroid follicular cells:
| 1. | directly into the blood |
| 2. | into the lumen of the thyroid follicle |
| 3. | into the surrounding interstitial fluid |
| 4. | into a duct that carries the hormone to blood vessels |
All terrestrial vertebrates at least have:
| 1. | A complete double circulation |
| 2. | A three chambered heart |
| 3. | A sino atrial node |
| 4. | A renal portal system |
The human heart receives:
1. Venous blood
2. Oxygenated blood
3. Deoxygenated blood
4. Mixed blood
A ‘closed circulatory system’ is considered advantageous over an ‘open circulatory system’ mainly because:
| 1. | Hemoglobin pigment would be present that increases the efficiency of oxygen transport |
| 2. | The volume of blood circulated can be larger |
| 3. | It will be easy to get the blood oxygenated in the lungs |
| 4. | Blood flow to various organs can be precisely regulated |
Let us say a person has a resting cardiac output of 6000 ml and 20% of this cardiac output is received by the kidneys. What is his renal plasma flow?
1. 1200 ml/minute
2. 660 ml/minute
3. 540 ml/minute
4. 125 ml/minute
