A common symptom produced by myocardial ischemia is:

1. Hypertension

2. Vertigo

3. Angina

4. Hyperventilation

The steps of the cardiac cycle in sequence are...

1. isovolumic contraction, isovolumic relaxation, ejection, passive ventricular filling, active ventricular filling.

2. isovolumic relaxation, isovolumic contraction, ejection, passive ventricular filling, active ventricular filling.

3. isovolumic contraction, ejection, isovolumic relaxation, passive ventricular filling, active ventricular filling.

4. isovolumic contraction, ejection, isovolumic relaxation, active ventricular filling, passive ventricular filling

An individual who is blood type AB negative

1. can receive any blood type in moderate amounts

2. can receive any blood type in moderate amounts except that with the Rh antigen

3. can donate to all blood types in moderate amounts

4. can receive types A, B and AB but not type O

The first heart sound or the 'lubb' is produced:

1. Near the end of the atrial systole

2. Immediately after the start of the ventricular systole

3. Near the end of the ventricular systole

4. Immediately after the start of the ventricular diastole

The right atria of the human heart receive:

1. Oxygenated blood

2. Deoxygenated blood

3. Arterial blood

4. Venous blood

The following is the diagrammatic representation of standard ECG. Identify the correct statement :

1. P is caused by atrial repolarization

2. Q, when present, always shows myocardial ischemia

3. QRS complex is due to time taken by impulse from SA node to AV node

4. T is caused by ventricular repolarization

In the given section of the human heart which part ensures that atria contact prior to the ventricles ?

1. A

2. B

3. C

4. D

The second largest constituent of plasma is:

Factors that can initiate coagulation of blood can be released by:
I. Platelets in the blood
II. Tissues at the site of injury
III. Liver
1. I and II only
2. I and III only
3. II and III only
4. I, II and III

Interstitial fluid resembles plasma in the same distribution of:
