Name the TWO major blood vessels that carry blood to and from the lungs.

The pulmonary artery (carries blood from the heart to the lungs), and the pulmonary vein (carries blood from the lungs to the heart).

Veins carry to the heart, and arteries carry blood from/away from the heart.

Explanation:

The pulmonary artery carries (oxygenated/oxygen rich) blood from the heart to the lungs, while pulmonary veins carry (deoxygenated/oxygen poor) blood to the heart, from the lungs.

explanation:

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
