Answer: E- The right ventricle.
Explanation: Deoxygenated blood with carbon dioxide and metabolic products collected from the tissues by the capillaries returns to the heart via the venous system and enters the right atrium of the heart. It is then pumped to the right ventricle, then transported to the lungs via the pulmonary artery for gaseous exchange, where oxygen is collected and carbon dioxide is dropped off.
This could be because star A is closer to Earth than star B is, making it appear brighter.
Blood is the fuel that keeps you going! Oxygenated blood is brought to organs and tissues via the arteries, while veins bring deoxygenated blood back to the heart to be replenished. The point is, without the respiratory system your blood would be useless.
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
