Which chamber of the heart pumps oxygenated blood to the body?
Right atrium
Right ventricle
Left atrium
Left ventricle
The heart of a newborn is located:
Higher and more horizontal than in adults
Lower and more vertical
In the same position as in adults
Closer to the diaphragm
What is the normal heart rate of a newborn?
60-80 bpm
120-160 bpm
80-100 bpm
160-200 bpm
Which structure closes functionally soon after birth?
Ductus arteriosus
Foramen ovale
Pulmonary artery
Coronary sinus
The foramen ovale connects:
Right ventricle and left ventricle
Right atrium and left atrium
Pulmonary artery and aorta
Superior and inferior vena cava
The fetal circulation bypasses the lungs mainly through:
Ductus arteriosus
Aortic arch
Pulmonary vein
Umbilical vein
The wall of the left ventricle is thicker because:
It pumps blood to the whole body
It receives blood from the lungs
It has more valves
It works less frequently
What is the average heart weight of a newborn?
20-25 g
30-40 g
10-15 g
50 g
The pulse in children is best palpated at the:
Brachial artery (infants)
Femoral artery
Radial artery
Carotid artery
Which of the following decreases as the child grows?
Heart rate
Blood pressure
Stroke volume
Cardiac output
In fetal circulation, oxygen-rich blood comes from:
Umbilical vein
Umbilical artery
Pulmonary vein
Ductus venosus
The normal blood pressure in a 5-year-old child is approximately:
80/40 mmHg
90/50 mmHg
100/60 mmHg
120/80 mmHg
In children, the apex beat is located at:
4th intercostal space, left midclavicular line
5th intercostal space
3rd intercostal space
2nd intercostal space
What causes the first heart sound (S1)?
Closure of atrioventricular valves (mitral and tricuspid)
Closure of semilunar valves
Opening of mitral valve
Atrial contraction
What causes the second heart sound (S2)?
Closure of aortic and pulmonary valves
Closure of mitral and tricuspid valves
Atrial contraction
Ventricular filling
Cardiac output in children depends mainly on:
Heart rate
Stroke volume
Blood viscosity
Venous return
The heart begins to beat in the embryo at about:
3rd week of intrauterine life
5th week
8th week
10th week
Which vessel carries deoxygenated blood from the fetus to the placenta?
Umbilical arteries
Umbilical vein
Ductus venosus
Inferior vena cava
Which of the following statements is TRUE about children's cardiovascular system?
Children have a higher metabolic rate and heart rate than adults
Stroke volume is higher than adults
Blood pressure is higher in infants
Heart sounds are less audible
The closure of the ductus arteriosus after birth is stimulated by:
Increase in oxygen concentration
Decrease in oxygen concentration
Decrease in heart rate
Increase in carbon dioxide
