The heart. the heart pumps the blood.
That muscle is known as the heart.
It is necessary for blood to pump through your body because it keeps you alive. It sends the blood to your organs and keeps them from failing.
Through your veins or your arteries. Through your veins or your arteries.
The heart pumps blood through the body
the cardiovascular muscle No Heart
After being oxygenated in the lungs, the blood enters the left atrium via the pulmonary veins. The left ventricle pumps the oxygenated blood to the rest of the body via the ao…rta. Blood cells carry oxygen, and the liquid portion of the blood, called plasma, carries the nutrients needed by the cells to perform their life functions. As oxygen enters the body cells, carbon dioxide, as a waste product from cellular respiration, diffuses into the blood, which returns to the right atrium of the heart via the superior and and inferior vena cavae, and is pumped to the lungs to be oxygenated via the right ventricle. As blood travels through the body, nutrients from the plasma enter the cells, and cell waste products enter the plasma. The liver and the kidneys cleanse the plasma portion of the blood, and nutrients are replenished via the small intestine. The plasma portion of the blood also carries hormones throughout the body, which are secreted by endocrine glands into the blood.
yes it is. the blood travels through tubes in the body called vessels. there are 4 types of vessel but i can't be bothered listing them!!!the smallest is the capillary vessel
(Just guessing to the best of my ability.) Because without blood circulation your body would become stiff, and start to rot away. Basically, your body needs to pump blood so… all of your organs will continue to function and to keep your body from just stiffening up and becoming a chunk of dead meat.
