sistema Cardiovascular

1- A respeito do desenho acima, que representa o coração de um mamífero, é INCORRETO afirmar que:

• artéria pulmonar que leva o sangue do coração para o pulmão

• a veia cava inferior que traz o sangue do corpo para o coração

• artéria cava superior que leva o sangue do coração para o corpo

• artéria aorta que leva o sangue do coração para o corpo.

Which blood vessels connect the heart and lungs?

• Pulmonary Artery

• Pulmonary Vein

• Aorta

• Superior vena cava

• Inferior vena cava

Which system permits blood to circulate and transports nutrients around the body?

• Nervous

• Respiratory

• Circulatory

• Digestive

Which of these orders the heart's chambers correctly? (hint: which way does blood flow?)

• Right atrium > Right ventricle > Left atrium > Left ventricle

• Right atrium > Left ventricle > Left atrium > Right ventricle

• Right atrium > Left atrium > Right ventricle > Left ventricle

• Right ventricle > Left ventricle > Right atrium > Left atrium

• No order, blood flows randomly

Why do the pulmonary artery and vein each have two branches?

• One carries blood TO the heart, and one carries blood AWAY FROM the heart.

• The vessels are too large to curve properly, so they must branch to reach the lungs.

• There are two lungs, and each has one pulmonary artery and one vein connected to it.

• Redundancy; if one vessel breaks or becomes blocked, the other can do its job.

___ takes place when blood travels from the heart, through the lungs, and back to the heart.

• pulmonary circulation

• systemic circulation
