The heart.
Brain :)
blood that picked up oxygen in the lungs enters the left atrium through the pulmonary veins. From there, it flows down to the left ventricles, where it is pumped out of the heart right through the systemic artery, the aroae, to all the body parts.
An organ called the blood, circulated by the circulatory system.
The heart is the organ responsible for pumping blood throughout the body. It consists of four chambers that work together to circulate oxygen and nutrients to all the tissues and organs via the bloodstream.
The heart is the life-sustaining organ of the human body, responsible for pumping blood throughout the circulatory system to deliver oxygen and nutrients to all parts of the body. Without the heart functioning properly, the body would not receive the necessary blood flow to sustain life.

The heart is the organ that supplies blood and oxygen to all parts of the body.
veins are important because they carry de-oxygenated blood from all parts of the body back to the heart , which sends blood to the lungs which then returns to the heart so that oxygen can be carried in the blood to all parts of the body. ( the body uses it in cellular respiration)
heart is a pumping organ of body whcih pumps oxygenated blood from lungs to the body part and dexoygenated blood from different body parts to lungs

Your brain sends singles to your body and your heart sends blood through your body
The heart is the pumping organ of the body, responsible for circulating blood throughout the cardiovascular system. It works by contracting and relaxing to pump blood to all parts of the body, delivering oxygen and nutrients while removing waste products.
With each heartbeat of your heart, blood is sent to all parts of our body carrying oxygen and nutrients to every cell. The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again. The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. By: Shiela Mae Aloot
