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
