The correct answer is "coarctation of the aorta". In coarctation of the aorta, there is an abnormal narrowing of the aorta, most commonly in the abdominal aorta, which compromises blood flow from going into the lower extremities. Patients with coarctation of the aorta most commonly presents with tachypnea as this is a high pressure congenital heart defect which makes breathing harder for the baby; diminished femoral pulses and poor lower body perfusion as the narrowing compromises blood flow. In physical examination, there will be a narrow ankle-brachial index, or the difference between the pulse pressures of the ankle (lower extremity) and the brachium (upper extremity).
Answer:
Electrons
Explanation:
According to the modern atomic theory, atoms are made-up of smaller subatomic particles in the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positively electrical charge and the neutrons have no charge. The electrons have a negative electrical charge and are able to move around the nucleus. An atom usually contains an equal number of positively charged protons and negatively charged electrons. This makes the atom itself electrically neutral. The electrons exist at different energy levels, called shells, around the nucleus where they revolve freely in a constant motion.
