Question

FROM THE LUNGS, BLOOD COMES BACK TO THE HEART. DESCRIBE THE PATH THIS BLOOD FOLLOWS UNTIL IT ENTERS THE AORTA.

Answer 1

Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body.

Answer 2

Answer:

Tricuspid valve  is the path of blood through the heart and lungs

Explanation:

Blood is also responsible for transiting the blood and nutrients. The blood reached right atrium and from here it reached the right ventricles with the help of tricuspid valve. When the ventricles are full it closes to stop blood from going back to the atrium.

The inferior and the superior vena cava let the blood enter through them. The heart left the blood with the help of pulmonary valve to the pulmonary artery and the blood reached the lungs.
