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?

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
