Blood starts on the SA node. When the atria are full, the electricity goes across either side to the left and right atria. It tells them to contract, pushing blood into the ventricles. The electricity then arrives at the AV nodes. Then it goes to the bundle of his, still in the ventricles. Here the electricity divides onto either side of the septum. The electricity goes through the Purkinje fibers, on the hearts wall. It spreads quickly through the ventricles, causing them to contract. This happens over and over, causing heart beats.
The blood enters the right atrium poor in oxygen, and then travels to the right ventricle and then through the aorta and arteries to the lungs to become oxygen rich and then through veins back to the section of the heart called the left atrium then to the left ventricle and out through arteries to the rest of the body to deliver the oxygen. Once delivered, it returns to the right atrium poor in oxygen to begin the cycle once more.
Oxygen-poor, or deoxyginated blood starts in the right atrium, goes through the right atrioventricular valve and enters the right ventricle. It then goes through the pulmonary valve into the pulmonary trunk. It then goes through pulmonary arteries to the lungs, enters the capillaries in the lungs to pick up oxygen, then returns to the heart through the pulmonary veins and into the left atrium. This is the path of de-oxygenated blood
Flowing electrons makes electricity (they flow from negative to positive. ). You need a circuit or a path for the electrons to move through, a power source like a battery or a generator, and something to use the electricity, like a light bulb...
Grounding is important, because it protects users of electricity from potentially fatal electrical shocks. This is accomplished through bolting, clamping or other effective mechanical means to provide an effective grounding path to the earth instead of through the user.
The path followed by the blood when it supplies and drains the heart muscle
the red blood cell will flow through your veins to your right atrium
Electricity takes the path of least resistance. When the electricity travels outside of the circuit, rather than through it, it is called a short circuit.
The path electricity takes is called a circuit.
The path electricity takes is called a circuit.
Path of Least Resistance.
The path of electricity is called a circuit.
Electricity takes the path of least resistance. Conductivity of a material has a larger impact than density does.
Electricity travels in the path of least resistance.
The electrical path is termed an electrical circuit.
a circuit
The path with the lowest resistance.
an incomplete circuit
the complete path that electricity can move through is called
