The cardiovascular system consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygennutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the heartThere are two primary circulatory loops in the human bodythe pulmonary circulation loop and the systemic circulation loop Pulmonary circulation transports deoxygenated blood from the heart to the lungs, where the blood picks up oxygen and returns to the the heart. What chamber(s) of the heart support the pulmonary circulation loop?

The Right ventricle and the Left atrium.

Explanation:

The pulmonary circulation loop starts in the right ventricle, where the

deoxygenated blood is. From there, the blood goes through the pulmonary semilunar valves and into the pulmonary trunk. The pulmonary trunk divides into two arteries, the left, and right pulmonary arteries. These arteries conduct the deoxygenated blood to the capillaries in the lungs where we exchange the CO₂ for O₂. Then, the oxygenated blood goes to the pulmonary venules and the pulmonary vein. The pulmonary vein conducts the oxygenated blood from the lungs to the left atrium of the heart. Lastly, the blood goes to the left ventricle, where the systemic circulation starts.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
