Q. No.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
I. Platelets in the blood
II. Tissues at the site of injury

Interstitial fluid resembles plasma in the same distribution of:
(1) Formed elements
(2) Proteins
(3) Minerals
(4) Enzymes
A tricuspid valve will prevent of blood flow from:
1 Right atrium to right ventricle
2. Right ventricle to right atrium
3. Left atrium to left ventricle
4. Left ventricle to left atrium
Purkinje fibers are:
(1) Intrinsic neural fibers in the ventricles
(2) Muscle fibers that interconnect SA node and AV node
(3) Muscle fibers that are distributed in the ventricular musculature
(4) Neural fibers that spread the impulse throughout the ventricular muscle mass
When the stroke volume of the ventricles is much less than the expected values, the heart is said to be:
(1) Fibrillating
(2) Blocked
(3) Arrested
(4) Failing
On a surface ECG, the end of ventricular systole is marked by:
(1) The end of the QRS complex
(2) The beginning of T wave
(3) The end of T wave
(4) The beginning of P wave
A normal blood pressure reading in a healthy adult human being would be:
I. 116/76 mm Hg
II. 150/80 mm Hg
III. 120/ 94 mm Hg
1. Only I
2. Both I and II
3. Both I and III
4. I, II and III
During the cardiac cycle, the AV valves close during:
1. Early ventricular systole
2. Late ventricular systole
3. Early ventricular diastole
4. Late ventricular diastole
A chronic condition in which the heart doesn’t pump blood as well as it should is called as:
1. Angina pectoris
2. Heart attack
3. Heart failure
4. Heart block
The cells that produce the smallest formed elements of the blood are called
1. erythroblasts
2. megakaryocytes
3. myeloblasts
4. thrombocytes
