   In other words, blood circulation is very important. A variety of things can affect blood circulation: blood vessel health, blood pressure, thyroid function, hydration, heart health, exercise, and ...

3. Circulatory system - Wikipedia

   en.wikipedia.org/wiki/Circulatory_system

   In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).

4. Hemodynamics - Wikipedia

   en.wikipedia.org/wiki/Hemodynamics

   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 being pumped out of the heart first enters the aorta, the largest artery of the body.

5. Local blood flow regulation - Wikipedia

   en.wikipedia.org/wiki/Local_blood_flow_regulation

   Pulmonary (lung) circulation undergoes hypoxic vasoconstriction, which is a unique mechanism of local regulation in that the blood vessels in this organ react to hypoxemia, or low levels of dissolved oxygen in blood, in the opposite way as the rest of the body. While tissues and organs tend to increase blood flow by vasodilating in response to ...

6. Blood - Wikipedia

   en.wikipedia.org/wiki/Blood

   Blood performs many important functions within the body, including: Supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells) Supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (e.g., blood lipids)) Removal of waste such as carbon dioxide, urea, and lactic ...

7. 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.

8. ABC (medicine) - Wikipedia

   en.wikipedia.org/wiki/ABC_(medicine)

   For this reason, maintaining circulation is vital to moving oxygen to the tissues and carbon dioxide out of the body. Airway, breathing, and circulation, therefore work in a cascade; if the patient's airway is blocked, breathing will not be possible, and oxygen cannot reach the lungs and be transported around the body in the blood, which will ...

9. Cardiorespiratory fitness - Wikipedia

   en.wikipedia.org/wiki/Cardiorespiratory_fitness

   The cardiovascular system responds to changing demands on the body by adjusting cardiac output, blood flow, and blood pressure. Cardiac output is defined as the product of heart rate and stroke volume which represents the volume of blood being pumped by the heart each minute. Cardiac output increases during physical activity due to an increase ...
