How does the pulmonary circulation differ from the systemic circulation?
It does not serve the metabolic needs of the body tissues.
What tissue is primarily associated with pulmonary circulation?
Lung tissue
What is the main function of the pulmonary circulation in regards to blood?
Brings blood into close contact with the alveoli to exchange carbon dioxide with oxygen
The arteries of the pulmonary circulation are structurally like what blood vessels?
Veins
The arteries of pulmonary circulation create what type of pressure in the lungs?
Create a low-pressure bed in the lungs
The healthy artertial pressure in the systemic circulation is what?
120/80
The pressure in the pulmonary artery is about what?
24/8
The bronchial arteries provide what to the lungs?
Functional blood
The bronchial arteries diverge from what portion of the descending aorta?
Thoracic aorta
Pumonary circulation begins with what artery? (Hint: also a trunk)
Pulmonary trunk
The pulmonary trunk leaves which ventricle?
Right ventricle
The pulmonary trunk divides into what 2 sets of arteries?
1. Left pulmonary arteries
2. Right pulmonary arteries
The right and left pulmonary arteries go into which organ?
The lungs
After entering the lungs, the right and left pulmonary arteries subdivide into which set of arteries?
Lobar arteries
How many lobar arteries are there on the right side?
3 on the right side
How many lobar arteries are there on the left side?
2 on the left side
The lobar arteries branch extensively in the lungs to form what type of blood vessel?
Arterioles
The arterioles terminate where?
In the capillary networks surrounding the alveolar sacs
Respiratory gases diffuse across at which 2 locations?
1. Walls of alveoli
2. Pulmonary capillaries
The pulmonary capillary beds are drained by what blood vessels?
Venules
The venules converge to form larger veins and finally what 4 veins?
The four pulmonary veins
How many pulmonary veins leave each lung?
2 pulmonary veins leave each lung
The 4 pulmonary veins return to which chamber of the heart?
Left atrium
