Oxygenated blood is red, and turns blue as the blood delivers its oxygen to tissues. By the time it reaches the heart, it is in a state of lowered oxygen levels, and the heart pushes it to the lungs where it may reoxygenate.

What is the normal pH of blood?
arterial blood pH = 7.41 (outgoing from heart) venous blood pH = 7.36 (returning to heart)
When a person strains to lift a heavy object intrathoracic pressure increases What do you think will happen to the rate of venous blood returning to the heart during such lifting?
The Output (ml/min) of the Left Ventricle increases proportionally (approx.) to the Filling Pressure (that is, the pressure with which the blood returns to the heart), measured with respect to Intrathoracic Pressure. An increase in the latter will then produce a decrease in Cardiac Output, so the rate of blood returning to the heart decreases. That is in the short term. But just after the increase in intrathoracic pressure, the Baroreceptors in the thorax sense the drop in pressure difference and trigger a reflex to increase Heart Rate, in order to restore blood flow. So if the lifting is prolongated, the rate of blood returning to the heart finally comes back to normal level. The opposite reaction is produced when you inhale deeply and hold your breath.
Harry faints due to transient vascular shock Explain why he fainted?
blood vessels dilated causing blood to "pool" instead of returning to the heart, thus lowering blood pressure and blood oxygen level, resulting in fainting.
How does blood move in a human body?
Blood is moved throughout the body through veins and arteries. Veins carry the deoxygenated blood back to the heart so it can move through the chambers, go to the lungs and pick up oxygen. Then the arteries take over by pumping the blood back out to the entire body. Veins are bluish in color because of the lack of oxygen. Arteries are the pulse in the body because they must pump the oxygenated blood to the entire body to supply all organs and tissues with oxygen rich blood. Hope this helps A RN in NJ
Where does blood travel in your body?
The heart pumps blood through blood vessels. Blood vessels leaving the heart are called arteries, and the blood vessels returning to the heart are called veins. Connecting the arteries and veins are smaller blood vessels called capillaries.It's pumped around through tubes called veins and arteries by the heart.The circulatory system is basically a closed network of tubes. The heart muscles contract, which squeezes blood into the arteries. There are valves in arteries and veins to stop the blood flowing 'backwards' - and so, with each heartbeat, the blood is forced forwards through the circulatory system before returning to the heart to start again.
Is the Heart chamber is the first to receive blood returning to the heart from the lungs?
The left atrium is the chamber that receives oxygenated blood returning from the lungs.
Is Systolic blood pressure related to blood returning to your heart?
no
Where do the blood returning to heart travel in?
Veins
Blood returning from the body (systemic circulation) enters which chamber of the heart?
Blood returning from the body systemic circulation first enters which chamber of the heart?
Where does blood returning to the heart go?
When your blood comes back to your heart it goes into the right atrium.
How is blood different when returning to the heart?
when blood is returning to the heart quite oxygenated as the heart need constant supply of blood. but i am not sure about this so you way to use a range of other sources to get a more reliable awnser.
Blood that leaves the heart is bright red it travels through arteries and capillaries when it reaches the veins on its way back to the heart it is dark bluish-red explain why this change occurs?
because the oxygen leaves the blood
Blood leaves the heart is bright red. It travels through arteries and capillaries. When it reaches the veins on its way back to the heart it is dark bluish-red. Explain why this change occurs?
because the oxygen leaves the blood
What is the the heart chambers that collect blood returning to the heart called?
Blood returning from pulmonary circulation returns to the right atrium via the pulmonary vein. Blood returning from the systemic circulation returns to the right atrium via the Vena Cava.
