How Does Blood flow to the Heart?
As the heartbeats, it pumps blood through a circulatory system, called the circulatory system. Arteries are elastic, muscular tubes that carry blood to all parts of the body.
Blood is essential. In addition to transporting oxygen from the lungs and nutrients to the tissues, it also removes body waste, including carbon dioxide, from the tissues. This is necessary to maintain good health and to promote good health in all parts of the body.
There are three main types of blood vessels:
Blood vessels. They start with the aorta, the main artery from the heart. Arteries carry oxygen-rich blood from the heart to all tissues. They branch out several times, becoming thinner and thinner as they move blood from the heart to the organs.
Capillaries.
These are small blood vessels that connect the arteries and veins. Their thin walls allow oxygen, nutrients, carbon dioxide, and other debris to enter and return to the cells of our organ.
Arteries.
These are the blood vessels that return blood to the heart; this blood is low in oxygen and rich in waste products to be excreted or excreted from the body. The arteries become larger and bigger as they get closer to the heart. The superior vena cava is the main artery that carries blood from the head and arms to the heart, and the inferior vena cava carries blood from the abdomen and legs to the heart.
