Histology Art for the Circulatory System (Colored Pencils)

The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart. Here are some prominent tissues found in the circulatory system.

  1. Heart. Your heart is at the center of your circulatory system. It is an organ about the size of your fist that pumps blood through your body. It is made up of multiple layers of tissue. This system is a network of blood vessels, such as arteries, veins, and capillaries, that carries blood to and from all areas of your body. Also, your heart’s electrical system controls the rate and rhythm of your heartbeat. A healthy heart supplies your body with the right amount of blood at the rate needed to work well. If disease or injury weakens your heart, your body’s organs will not receive enough blood to work normally.

  2. Vena cava. A large vein that carries blood to the heart from other areas of the body. The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.

  3. Artery. Arteries are elastic, muscular tubes. These blood vessels operate at a high pressure to help transport oxygen-rich blood away from the heart and deliver oxygen, nutrients, and hormones throughout the body. Arteries branch repeatedly to form microscopic arteries, known as arterioles, to distribute blood into capillary beds. Capillaries are blood vessels that carry blood to the body’s organs at a microscopic level.
