Bradykinin (BK) (from Greek brady-'slow' + -kinin, kīn(eîn) 'to move') is a peptide that promotes inflammation.It causes arterioles to dilate (enlarge) via the release of prostacyclin, nitric oxide, and endothelium-derived hyperpolarizing factor and makes veins constrict, via prostaglandin F2, thereby leading to leakage into capillary beds, due to the increased pressure in the capillaries.
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
De-oxygenated blood leaves the heart, goes to the lungs, and then enters back into the heart. [2] De-oxygenated blood leaves through the right ventricle through the pulmonary artery. [2] From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve) into the right ventricle.
For a healthy heart, the best breakfast is one that provides 20% to 30% of daily calorie intake, while wating either less or more may increase certain cardiometabolic risk factors in older adults.
Venous thrombosis can lead to pulmonary embolism when the migrated embolus becomes lodged in the lung. In people with a "shunt" (a connection between the pulmonary and systemic circulation), either in the heart or in the lung, a venous clot can also end up in the arteries and cause arterial embolism.
