C Correct answer
Explanation

A stethoscope requires a flexible tube to transmit sound waves from the chest piece to the earpieces. Rubber is the standard material due to its flexibility and acoustic properties.

Which of the following can be used to make a stethoscope at home?

  1. Rubber tube

  2. Balloon

  3. Funnel

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Steps to construct a stethoscope at home:

1) Take a funnel and put its small end at one end of the flexible tube. Push the funnel as far as u can into the tube.
2) Tape the funnel using suitable tape.
3) Inflate the balloon to stretch it out. Let the air out and then cut the neck of the ballon.
3) Stretch the remaining part of the balloon tightly over the open end of the funnel, and tape it. This creates the tympanic membrane for the stethoscope
4) Place the funnel end of the stethoscope on to the chest and end of the tube to the ear to listen to the heartbeat.
Hence rubber tube, balloon and funnel can be used to make a stethoscope at home.
So, the correct answer is 'All of the above'.

Raman went to the doctor. On which side of the chest will the doctor keep the stethoscope for hearing his heartbeat?

  1. Right side

  2. Middle

  3. Left side

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In humans, heart is present in the chest region. It is located between the lungs and above the diaphragm. The heart is made of auricles and ventricles. Ventricles are the pumping chambers of the heart. The right ventricles pump blood to the lungs and the left ventricles pump blood to the whole body. The heart is slightly tilted towards the left side and so a stronger heartbeat can be felt on left side. Hence the doctor will keep the stethoscope for hearing Raman's heartbeat on the left side of his chest.

Thus the correct answer is option C.

The movement in the vessels on the wrist is due to the 

  1. Beat

  2. Pulse

  3. Pulse rate

  4. Heartbeat
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This sequential event in the heart which is cyclically repeated is called the cardiac cycle. Each cardiac cycle consists of systole and diastole of both the atria and ventricles. Each cardiac cycle represents one heartbeat. The normal heart rate is about 72 beats per minute. The heart rate is same as pulse rate because the pumping action of the heart causes an increase in blood pressure in arteries. Hence the movement in the vessels on the wrist is due to the pulse.

So, the correct answer is 'Pulse'.

Shyam was cutting wood in the forest. A lion appeared from the bushes. What will happen to his heart beat?

  1. Remain same

  2. Increase

  3. Decrease

  4. Firsts decrease and then increase
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The body's reaction to fear is called the "fight or flight" response. The heart rate increases to pump more blood to the muscles and brain. The lungs take in air faster to supply  body with oxygen.

So, the correct answer is 'Increase'.

Assertion : Smaller the organism higher is the rate of metabolism per gram weight.

Reason : The heart rate of six month old baby is much higher than that of an old person.

  1. Both Assertion and Reason are true and Reason is a correct explanation of Assertion

  2. Both Assertion and Reason are true but Reason is not a correct explanation of Assertion

  3. Assertion is true but Reason is false

  4. Both Assertion and Reason are false

  5. Assertion is false but reason is true.

A Correct answer
Explanation

Smaller organisms have a higher surface-area-to-volume ratio, leading to faster heat loss and higher metabolic rates. The heart rate comparison is a valid physiological example of this trend.

The pulse rate per minute describes the

  1. Oxygenation rate

  2. Heartbeat

  3. Pulse

  4. Both B and C
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This sequential event in the heart which is cyclically repeated is called the cardiac cycle. Each cardiac cycle consists of systole and diastole of both the atria and ventricles. Each cardiac cycle represents one heartbeat. The normal heart rate is about 72 beats per minute. The heart rate is same as pulse rate because the pumping action of the heart causes an increase in blood pressure in arteries that leads to noticeable pulse. Hence the pulse rate per minute describes the heartbeat.

So, the correct answer is 'Heartbeat'.

The rhythmic beating of the heart is due to 

  1. The action of the muscles in the atria only

  2. The action of the muscles in the atria and ventricles

  3. The action of the muscles in the ventricles only

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The entire heart is made of cardiac muscles. A specialized cardiac musculature called the nodal tissue is also distributed in the heart i.e sino-atrial node (SAN- A patch of this tissue is present in the right upper corner of the right atrium )and atrioventricular node (AVN- mass of this tissue is seen in the lower left corner of the right atrium close to the atrioventricular septum). The nodal musculature has the ability to generate action potentials without any external stimuli, i.e., it is autoexcitable. Hence, the rhythmic beating of the heart is due to the action of muscles in the atria and ventricle.

So, the correct answer is 'The action of muscles on the atria and ventricles '.
