Place the parts of the circulatory system in the correct order to describe the flow of oxygenated and deoxygenated blood in the human body.

deOxygenated blood, superior vena cava,right atrium, right ventricle, pulmonary artery, lungs

oxygenated blood, Lungs, Pulmonary veins, left atrium, left ventricle, aorta

D: The Sun and the planet attract each other with their gravitational forces.

B:The planet speeds by the Sun with a lot of momentum.

A: The planet continues to move forward due to momentum, while the Sun’s gravity pulls the planet back.

C: The planet moves along a closed orbital path around the Sun.

Explanation:

There are 8 planets in the solar system which revolve around the sun in an elliptical orbit with sun at one of its focii. The planets are bound in the orbits around the Sun due to gravitational pull.

The Sun being heavier, the planets speeds by it with a lot of momentum. As the planet continues move forward due to momentum, the sun pulls back them due to gravity. Then, the planets move along a closed orbital path around the sun.
