The blood goes through the heart in the correct direction because there are a number of one-way valves in the heart chambers that blood can only pass through in the correct direction.
NO
Valves open and close to control the flow of blood in a one-way direction through your heart. These valves prevent the backflow of blood and ensure that it travels in the correct sequence through the heart chambers.
valves
Valves, allown blood through in one direction when the pressure builds up but close when pressure is applied in the opposite direction.
valves
Valves.
One directional valves keep blood in the heart flowing in the right direction. There are three valves: biscupid valve, semilunar valve and tricuspid valve. These open to let the blood flow through then close to prevent the blood flowing back in the wrong direction making the heart less efficient.
The change in direction of blood flow typically occurs at the level of the heart, which pumps oxygenated blood to the rest of the body through arteries and receives deoxygenated blood back through veins. The specific altitude at which changes in blood flow may occur can vary depending on factors such as oxygen levels, exertion, and individual health.
it depends on the type of blood vessel if we say of veins so movement is in upward direction if we say about arteries so movement is downward.
