Test: Cardiac Cycle (NCERT) - Question 1

What is the average cardiac output for a healthy individual?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 1

The average cardiac output of a healthy adult is 5000ml or 5 liters. This means that if the heart rate is 72 beats per minute and the stroke volume is 70ml, then around 5000ml of blood is pumped by each ventricle in one minute.

Test: Cardiac Cycle (NCERT) - Question 2

Which one of the following is a matching pair?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 2

During ventricular systole, the contraction of ventricular muscles causes the closure of bicuspid and tricuspid valves (AV valves), producing a low pitched 'lubb' sound. At the end of ventricular systole, semilunar valves close, producing the second heart sound, the 'dup'. Pulsation of the radial artery is due to rhythmic contraction and relaxation in the aorta. Initiation of the heart beat occurs in the SA node.

Test: Cardiac Cycle (NCERT) - Question 3

During ventricular systole:

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 3

Due to contraction of the ventricles (ventricular systole), the pressure inside the ventricles rises, that force open the semilunar valves of aorta and pulmonary artery so that the blood enters into these vessels. Oxygenated blood is pumped into the aorta from the left ventricle while deoxygenated blood is pumped into the pulmonary artery from the right ventricle.

Test: Cardiac Cycle (NCERT) - Question 4

During the arterial systole,

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 4

Ventricles are in relaxed phase during arterial systole. In arterial systole, simultaneous contraction of the auricles takes place and as a result, blood passes into the ventricles which are in relaxing phase.

Test: Cardiac Cycle (NCERT) - Question 5

Which one of the following statements is correct regarding blood pressure?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 5

Normal blood pressure is 120/80 mm Hg. Blood pressure of 190/110 mm Hg is regarded as high blood pressure. It leads to heart diseases and also affects vital organs like brain and kidney.

Test: Cardiac Cycle (NCERT) - Question 6

Consider the following statements each with one or two blanks.
(i) Left auriculoventricular aperture is guarded by (1) valve while right auriculoventricular aperture is guarded by (2) valve.
(ii) In man left auricle receives (3) blood by (4) pulmonary veins.
(iii) (5) ions play a significant role in clotting.
Which one of the following options, gives the correct fill-ups for the respective blank numbers from (1) to (5) in the statements?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 6

The correct fill-ups for the respective blank numbers are as follows:
1. bicuspid valve
2. tricuspid valve
3. oxygenated
4. four
5. calcium
Explanation:
(i) Left auriculoventricular aperture is guarded by the bicuspid valve while the right auriculoventricular aperture is guarded by the tricuspid valve. This means that the correct fill-ups for the blanks in statement (i) are (1) bicuspid valve and (2) tricuspid valve.
(ii) In man, the left auricle receives oxygenated blood by four pulmonary veins. Therefore, the correct fill-ups for the blanks in statement (ii) are (3) oxygenated and (4) four.
(iii) Calcium ions play a significant role in clotting. Thus, the correct fill-up for the blank in statement (iii) is (5) calcium.
Therefore, option B: (1) bicuspid valve, (2) tricuspid valve, (5) calcium is the correct answer.
Test: Cardiac Cycle (NCERT) - Question 7

Which of the following statement(s) regarding the cardiac system is/are correct?
(i) Human heart is an ectodermal derivative.
(ii) Mitral valve guards the opening between the right atrium and left ventricle.
(iii) SAN is located on the left upper corner of the right atrium.
(iv) Stroke x Heart rate = Cardiac output.

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 7

During a cardiac cycle, each ventricle pumps out approximately 70 mL of blood which is called stroke volume. The stroke volume multiplied by the number of heart beats per minute (heart rate) gives the cardiac output. Therefore, Cardiac output = Stroke × heart rate =70×72=5040 mL per minute i.e., 5 litres per minute.

Test: Cardiac Cycle (NCERT) - Question 8

The problem of electrical discontinuity caused in the normal heart by the connective tissue separating the atria from the ventricles is solved by?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 8

Correct option is A.
A-V node functions as a secondary pacemaker because when the wave of contraction originating from the sinoatrial node reaches the atrioventricular node (AV node – pace setter), the latter is stimulated and excitatory impulses are rapidly transmitted from it to all parts of the ventricles to contract simultaneously. The ventricles force blood through long system of arteries and hence must exert great pressure on the blood.

Test: Cardiac Cycle (NCERT) - Question 9

'X' is the rhythmic contraction and relaxation in the aorta and its main arteries. What is X?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 9

Pulse is the rhythmic contraction and relaxation in the aorta and its main aeteries. It is a regular jerk of an artery. It is same as the heart rate because an artery pulses every time the heart beats.

Test: Cardiac Cycle (NCERT) - Question 10

The figure given below three stages in the cardiac cycle

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 10

In figure (2), blood is entering into the right auricle through superior and inferior vena cava and blood is entering into left auricle through pulmonary vein. Figure (1) shows movement of blood from the auricles into the ventricles. Figure (2) shows movement of blood from the right ventricle into the pulmonary artery and from the left ventricle into aorta.

Test: Cardiac Cycle (NCERT) - Question 11

A red blood cell, entering the right side of the heart passes by or through the following structures.
1. Atrioventricular valves
2. Semilunar valves
3. Right atrium
4. Right ventricle
5. SAN
Which of the following options represents the correct sequence?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 11

Red blood cell (blood) will first meet SAN in the right atrium. Then from the right atrium it passes into right ventricle through atrio ventricular valve. From the right ventricle it enters into pulmonary artery through semilunar valve.

Test: Cardiac Cycle (NCERT) - Question 12

Consider the following four statements (i) - (iv) and select the correct option.
(i) SA node is natural pacemaker of heart.
(ii) Human heart has inter-auricular foramen.
(iii) Right atrioventricular valve is a semilunar valve.
(iv) Normal systolic and diastolic pressure of humans is 120 and 60 mm Hg respectively.

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 12

i. S-A node has a unique property of self-excitation, which enables it to act as the "pacemaker" of the heart.

ii. The two auricles are separated from each other by a partition, the interauricular septum. The septum has an oval, thin area called the fossa ovalis. It marks the position of an opening the foramen ovale, between the two auricles in the foetus.

iii. The right auricle opens into the right ventricle through a wide passage, the right auriculoventricular or A-V aperture. This aperture is guarded by a one-way valve called tricuspid valve.

iv. In a normal adult person, the average systolic/ diastolic pressure are 120*80 mm Hg.

So, the correct answer is 'i-T, ii-F, iii-F, iv-F'.

Test: Cardiac Cycle (NCERT) - Question 13

In the given figure the durations of the events of the cardiac cycle are given. Identify these events and select the correct option.

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 13

Duration of joint diastole is 0.4 sec, that of auricular systole is 0.1 sec and that of ventricular systole is 0.3 sec.

Test: Cardiac Cycle (NCERT) - Question 14

Right atrium receives blood from

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 14

Superior vena cava and inferior vena cava are the large veins. Superior vena cava brings deoxygenated blood from upper part of the body while inferior vena cava brings blood from lower part of the body into the right atrium of the heart.

Test: Cardiac Cycle (NCERT) - Question 15

What happens when the pacemaker becomes nonfunctional?

Detailed Solution for Test: Cardiac Cycle (NCERT) - Question 15

The SA node possesses a unique property of self-excitation, which enables it to act as the pacemaker of heart. It spontaneously generates a wave of contraction which spreads over both the auricles more or less simultaneously along the muscle fibres that fan out from the pacemaker. The pacemaker establishes the basic rhythm at which the heart beats. Thus, if the pacemaker becomes nonfunction, then the cardiac muscles do not undergo co-ordinated rhythmic movements.
