Weekly Quiz Competition

Question 1
1 / -0

Identify the correct match between Set-I and Set-II.
Set-I Set-II
A) ECG I)Non invasive imaging
B) EEG II) Radiation
C) MRI III) Heart
D) X-ray IV) Blood serum
V) Brain

A
A- IV, B- I, C- V, D- II

B
A- I, B- V, C- III, D- II

C
A- V, B- I, C- IV, D- I

D
A- III, B- V, C- I, D- II

Solution

An electrocardiogram (ECG) is a test to measure the electrical activity of the heart. It indicates the working of the heart. It records the heart's rhythm and activity on a moving strip of paper. An electroencephalogram (EEG) is a test to measure the electrical activity of the brain. It indicates the working of the brain. The activity is seen as wavy lines on an EEG recording. A Magnetic Resonance Imaging (MRI) is a non-invasive imaging technology which is used to produce 3D anatomical images without the use of radiation. It is used for disease detection, diagnosis and treatment monitoring. An x-ray is a form of electromagnetic radiation that is used to take images of the human body without dissecting the body.
Thus, the correct answer is option D.
Question 2
1 / -0

The blood cells, which do not have a nucleus are:

A
Red blood cells

B
White blood cells

C
Blood platelets

D
None of these

Solution

The group of blood cells which are responsible for the transport of oxygen through the blood vessels, across the body are called red blood cells. These cells do not have a nucleus and other cell organelles inside them.
So, the correct answer is Red blood corpuscles.
Question 3
1 / -0

Maximum and minimum Erythrocyte Sedimentation Rate (ESR) is found in which of the following infections respectively?

A
Bacterial and worm

B
Worm and viral

C
Viral and bacterial

D
Viral and worm
Question 4
1 / -0

Mature human red blood cells (RBCs) do not contain __________.

A
Iron

B
Cytoplasm

C
Mitochondria

D
Haemoglobin

Solution

A mature RBC in mammals are devoid of nucleus and most organelles, including mitochondria so that almost the entire cell can be packed with hemoglobin for gaseous transport and becomes even more efficient as an oxygen carrier.
So, option C is the correct answer.
Question 5
1 / -0

Consider the following statements:
1. Arteries carry oxygenated blood from the heart to body tissues.
2. The pulmonary artery carries deoxygenated blood.
3. Veins carry deoxygenated blood from body tissues towards the heart.
4. Pulmonary vein carries oxygenated blood.
Which of the statements given above are correct?

A
1 and 2

B
1 , 2 and 3

C
2 , 3 and 4

D
All of the above
Question 6
1 / -0

ECG records

A
Electric current of the body

B
Potential differences

C
Pulse rate

D
Quantity of blood pumped per minute

Solution

Full form of ECG is electrocardiogram records. It is used to check the heart's rhythm and electrical activity. It can be used to detect the electrical signals produced by the heart each time it beats with the help of the sensors attached to the skin. So, the correct answer is 'Electric current'.
Question 7
1 / -0

What is the genotype of human blood group O?

A
$$I^A I^A$$

B
$$I^A I^B$$

C
$$ii$$

D
$$I^A i$$

Solution

A person with blood type O has neither the A nor the B allele. The genotype must be $$ii$$.
Thus the correct answer is option C.
Question 8
1 / -0

Which of the following statement is false?

A
Angina pectoris is the condition in which inadequate oxygen is supplied to the walls of the heart.

B
Blood pressure means speed of blood in each tubule of the body.

C
Closed circulatory system is commonly found in vertebrates.

D
Fishes have two chambered heart.

Solution

Blood pressure is the pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
The correct answer is option B.
Question 9
1 / -0

Which of the following labelled parts in the given figure is/are involved in the pH and ionic balance of the body fluids?

A
P and R

B
P, Q and S

C
Q only

D
P, R and S

Solution

The correct answer is D.
P) Reabsorption takes place mainly in the proximal convoluted tubule of the nephron . Nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration reenter the blood from the renal tubules.
R) DCT maintains pH and ionic balance in the blood by reabsorption of Na+ , water and HCO3 and selective secretion of H+, K+ and NH3.
S) Collecting duct plays a role in the maintenance of pH and ionic balance of blood by reabsorption of water, and selective secretion of H+ and K+ ions.
Question 10
1 / -0

Which one is correct regarding electrocardiogram(ECG)?

A
P-wave represents the electrical excitation of the ventricles

B
QRS complex represents repolarisation of the ventricles

C
T-wave represents repolarisation of the atria

D
By counting the time between two QRS complexes one can determine the pulse rate
