  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 .

  3. Cardiac cycle - Wikipedia

    en.wikipedia.org/wiki/Cardiac_cycle

    Circulation is split into pulmonary circulation—during which the right ventricle pumps oxygen-depleted blood to the lungs through the pulmonary trunk and arteries; or the systemic circulation—in which the left ventricle pumps/ejects newly oxygenated blood throughout the body via the aorta and all other arteries.

  4. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs. In the lungs the blood is oxygenated and returned to the left atrium to complete the circuit. [1]

  5. Coronary circulation - Wikipedia

    en.wikipedia.org/wiki/Coronary_circulation

    Coronary circulation is the circulation of blood in the arteries and veins that supply the heart muscle (myocardium). Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated.

  6. Hemodynamics - Wikipedia

    Blood then returns to the left side of the heart where it begins the process again. In a normal circulatory system, the volume of blood returning to the heart each minute is approximately equal to the volume that is pumped out each minute (the cardiac output). [12]

  7. Coagulation - Wikipedia

    en.wikipedia.org/wiki/Coagulation

    Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The process of coagulation involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of ...

    Although deep-space travel is a far-future application, the team notes that changing the mechanical properties of human blood cells could help optimize blood circulation for pharmaceutical means ...

  9. Blood vessel - Wikipedia

    en.wikipedia.org/wiki/Blood_vessel

    Blood is 92% water by weight and the rest of blood is composed of protein, nutrients, electrolytes, wastes, and dissolved gases. Depending on the health of an individual, the blood viscosity can vary (i.e., anemia causing relatively lower concentrations of protein, high blood pressure an increase in dissolved salts or lipids, etc.).
