All vertebrate cardiovascular systems include a heart, a muscular pump that contracts to (i) ________ .blood through the blood vessels. The upper chamber of the heart is the atrium, and is where blood enters the muscle. The lower chamber is the ventricle. When the ventricle (ii) ________ , blood is forced from the heart via an artery. The aorta is the main artery leaving the heart and bringing nutrients and oxygen out to the other organs. The pulmonary artery returns the oxygen-(iii) ________ .blood to the heart so that it can be enriched with nutrients and sent back out into the body.

To propel is to cause something to move forward. The contraction of the heart muscle moves blood forward and out of the muscle. To pitch is to throw, which does not apply to liquid moved through a closed system. Influence and project should be eliminated. Project is similar to pitch as it refers to throwing or casting something out. The sense of force and forward motion is not evident.
To constrict is to squeeze from all sides. To compress is to press together to create a solid mass. To cinch is to circle something with a tight grip. Constricts is the correct choice as it refers to the pressure exerted to send blood out of the heart.
Depleted means seriously decreased or exhausted. Blood depleted of oxygen must be enriched. Squandered means wasted. The oxygen in the blood is not wasted; rather it is consumed by the body systems. Augmented is an antonym, which means added to. As the blood travels the circulatory system different organs and systems use the oxygen. By the time the blood returns to the heart, the oxygen has been depleted making it the best choice.
