Ions of the heart

WebThe heart's primary function is to pump blood to all parts of the body, providing oxygen and nutrients to the cells and organs. Blood is pumped through a network of blood vessels, including arteries, veins, and capillaries. The heart also helps to remove waste products from the body, such as carbon dioxide. Webions rush into the cell through that patch. These ions spread out laterally inside the cell and can depolarize a neighboring patch of membrane, triggering the opening of voltage-gated sodium channels and causing the …
