  2. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    The circulation of lymph takes much longer than that of blood [7] and, unlike the closed (blood) circulatory system, the lymphatic system is an open system. Some sources describe it as a secondary circulatory system. The circulatory system can be affected by many cardiovascular diseases.

  3. 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.

    Diagram of the circulatory system. SVC/IVC - Superior/Inferior vena cava, The heart is the driver of the circulatory system, pumping blood through rhythmic contraction and relaxation. The rate of blood flow out of the heart (often expressed in L/min) is known as the cardiac output (CO).

    Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. [1] Blood is composed of blood cells suspended in blood plasma.

  8. 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 ...

    General diagram of a portal venous system, for example, this occurs in the hypophyseal portal system between the hypothalamus and the anterior pituitary gland.. In the circulatory system of vertebrates, a portal venous system occurs when a capillary bed pools into another capillary bed through veins, without first going through the heart.
