Which of the following is true regarding pulmonary circulation?
The system functions with an increased arterial pressure to circulate
through the distal parts of the body.
It is the larger of the two circulatory systems.
It is a low-pressure system that allows for improved gas exchange.
It consists of the left side of the heart, the aorta, and its branches. -
Correct Answer-It is a low-pressure system that allows for improved
gas exchange.
Explanation:
The pulmonary circulation consists of the right heart and the
pulmonary artery, capillaries, and veins. It is the smaller of the
systems and functions at a lower pressure to assist with gas exchange.
Which sequence is the correct pathway for blood flow through the
heart?
left atrium - bicuspid valve - left ventricle - pulmonary artery - lungs -
pulmonary vein - right atrium - tricuspid valve - right ventricle - aorta
right atrium - tricuspid valve - right ventricle - pulmonary artery -
lungs - pulmonary vein - left atrium - mitral valve - left ventricle -
aorta
right atrium - bicuspid valve - right ventricle - pulmonary artery -
lungs - pulmonary vein - left atrium - tricuspid valve - left ventricle -
aorta
left atrium - tricuspid valve - left ventricle - pulmonary artery - lungs -
pulmonary vein - right atrium - mitral valve - right ventricle - aorta -
Correct Answer-right atrium - tricuspid valve - right ventricle -
pulmonary artery - lungs - pulmonary vein - left atrium - mitral valve
- left ventricle - aorta
Explanation:

The correct pathway for blood flow through the heart is the right
atrium - tricuspid valve - right ventricle - pulmonary artery - lungs -
pulmonary vein - left atrium - mitral valve - left ventricle - aorta.
Which of the following blood flow patterns reduces friction, allowing
the blood layers to slide smoothly over one another?
Axially
Laminar
Turbulent
Crosswise - Correct Answer-Laminar
Explanation:
Laminar blood flow reduces friction by allowing the blood layers to
slide smoothly over one another, with the axial layer having the most
rapid rate of flow. Axially, crosswise, and turbulent blood flow would
result in increased friction. In turbulent flow, the laminar stream is
disrupted and the flow becomes mixed, moving radially (crosswise)
and axially (lengthwise).

heart?
left atrium - bicuspid valve - left ventricle - pulmonary artery - lungs -
pulmonary vein - right atrium - tricuspid valve - right ventricle - aorta

Correct Answer-
A client has had an acute myocardial infarction (MI). The brother of
the client has a history of angina. The client asks how he will know if
his brother's pain is angina or if the brother is actually having an MI.
