Q

Third place the blood flows?

A

Pulmonary semilunar valve

Q

Fourth place the blood flows?

A

Pulmonary arteries

Q

Fifth place the blood flows?

A

After it goes through the capillary lungs it goes into the pulmonary veins

Q

Sixth place the blood flows?

A

Left atrium

Q

Seventh place the blood flows?

A

Bicuspid valve

Q

The last place the blood flows (eighth)?

A

Through the aortic semilunar valve
-Goes out the Brachiocephalic trunk, left common carotid artery, and left subclavian artery AND into the superior vena cava

Q

What does isovolumetric mean?

A

Equal volumes of blood are pumped to the pulmonary and systemic circuits
Iso = equal volume of blood

Q

Pulmonary circuit?

A

Low-pressure circulation

Q

Systemic circuit blood?

A

Higher resistance in the long pathways

Q

What causes a blockage in the heart? (5 causes)

A

Plaque
1. Fat
2. Cholesterol
3. Calcium
4.Waste products from cells
5. Fibrin (clotting agent)
