    Diagram showing the circulatory system of the body. The circulatory system consists of the heart and blood vessels (arteries, veins and capillaries). The heart propels the circulation of the blood, which serves as a "transportation system" to transfer oxygen, fuel, nutrients, waste products, immune cells and signaling molecules (i.e. hormones ...

    en.wikipedia.org/wiki/Atrium_(heart)

    In most fish, the circulatory system is very simple: a two-chambered heart including one atrium and one ventricle. Among sharks, the heart consists of four parts arranged serially: blood flows into the most posterior part, the sinus venosus, and then to the atrium which moves it to the third part, the ventricle, before it reaches the conus ...

  6. Blood vessel - Wikipedia

    en.wikipedia.org/wiki/Blood_vessel

    The circulatory system uses the channel of blood vessels to deliver blood to all parts of the body. This is a result of the left and right sides of the heart working together to allow blood to flow continuously to the lungs and other parts of the body. Oxygen-poor blood enters the right side of the heart through two large veins.

  7. Vein - Wikipedia

    en.wikipedia.org/wiki/Vein

    In the circulatory system, blood first enters the venous system from capillary beds where arterial blood changes to venous blood. Large arteries such as the thoracic aorta, subclavian, femoral and popliteal arteries lie close to a single vein that drains the same region. Other arteries are often accompanied by a pair of veins held in a ...

  8. Heart - Wikipedia

    en.wikipedia.org/wiki/Heart

    The heart is a muscular organ found in most animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
