Answer:
They don't have hearts or even an arterial system (veins, arteries). They have an "air system" which is a set of open tubes running through the body from openings on the body called spiracles. It's highly efficient for very small living creatures; it is used by a lot of insects. The problem with it for larger animals is that there is nothing to force higher rates of oxygen when necessary to parts of the body so the system is limited by movement (think of sharks who cannot stop and just float - they don't force water past the gills, their movement forces water through the gills. If the shark stops, he stops breathing -- BAD!) Faster movement can cause faster oxygen flow, to a limit, then the air ceases to flow (turbulence has set in) and oxygen deprivation sets in. {Yay us, boo mosquito.}

Is the mammalian heart a two sided muscular pump?
Yes- the mammalian heart is a big muscle that has a right and a left side, each with two small chambers: the ventricle and the atrium. Each chamber of the heart pumps at a slightly different time, but each atrioventricular pair pumps closer together than to the other two, leading to to the rhythmic two-pump sound you can hear through your chest.
What is the hollow muscular organ that pumps blood through the body?
Your Heart is an organ that pumps blood through your body.
What are between the chambers of the heart?
pumps
What are the downstairs chambers of a heart?
The downstairs chambers of the heart are the right and left ventricles. These muscular chambers are responsible for pumping blood out of the heart: the right ventricle sends deoxygenated blood to the lungs for oxygenation, while the left ventricle pumps oxygenated blood to the rest of the body. Their strong muscular walls are essential for generating the pressure needed to propel blood effectively.
What pumps the blood out of the heart?
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)
What are actual pumps of the heart?
The pumps inside the heart are four chambers that work together to pump blood to your lungs and your body. There are two upper chambers called atria and two lower larger chambers called ventricles.
What lower chambers of the heart that pumps blood out of the organ?
Ventricles
What are the lower chambers of the heart that pumps blood out of the organ?
Ventricles
What are the lower hambers of the heart?
The lower chambers of the heart are called the ventricles. There are two ventricles: the right ventricle, which pumps deoxygenated blood to the lungs for oxygenation, and the left ventricle, which pumps oxygenated blood to the rest of the body. Both ventricles have thicker muscular walls compared to the upper chambers (atria) to effectively handle the pressure required for blood circulation.
What is collecting the chambers of the heart?
The heart has 4 chambers. The "collecting chamber of the heart", or the atria , is the two chambers that are located above the other two chambers. It carries the responsibility in helping to pump the blood out of the chambers and making sure no blood pumps back in.
Which organ pumps blood?
The heart pumps blood through the rest of the body.
Is a heart symmetrical?
The human heart is not perfectly symmetrical. It has a distinct shape with the left side being larger and more muscular than the right side, as it pumps blood to the entire body, while the right side primarily pumps blood to the lungs. Additionally, the heart's chambers and valves are arranged in a specific configuration that contributes to its asymmetrical appearance.
