The blood leaving the kidneys have most of the waste products removed.
The kidneys do use some of the oxygen in the blood, but only a tiny amount, so the outflow is essentially clean arterial blood.
composition of blood entering kidneys are,
while the compositions of blood leaving kidneys are,
It enters by the renal arteries and leaves by the renal veins.
Blood leaving the left side of the heart is higher in oxygen than blood entering the right side.
filtering reabsorbing and removing
2 valves: pulmonary valve- blood leaving from the right ventricle passes through it towards the lungs; aortic valve- blood leaving from the left ventricle passes through it to the body (by way of the aorta)
the heart pumps the blood to different part of the body
They're both blood vessels. But unlike a artery which carries oxygenated blood away from the heart, the veins carry de-oxygenated blood back to the heart where it can exchange gases in the lungs later. Also, veins have valves (to prevent blood flowing backwards) where as arteries generally do not.
The arterial ligament in adults was once the arterial duct (ductus arteriosus) in the fetus. This is a connection between the pulmonary trunk, the large vessel leaving the right side of the heart that in an adult would be conducting deoxygenated blood to the lungs for some oxygen, and the aorta, the large vessel leaving the heart with the oxygenated blood for the rest of the body. Along with the ductus venosus, moving oxygenated blood from the mother/placenta directly to the large vein feeding the heart, and the foramen ovale connecting the two atria inside the heart, fetal blood flow from the heart mostly bypasses the lungs and goes right into general circulation. The primary reason for this is that the lungs are not being used to collect oxygen from the environment, as the placenta is exchanging oxygen from the mother's blood to the fetal blood.
After blood loss, the body will seek to compensate for the lack of blood by entering a state of Hypovolemic Shock. This is followed by the body releasing hormones that will constrict the blood vessels in an attempt to keep the blood in the body. Heart rate and respiratory rate will increase for a while. However, if action isn't taken, both respiratory and heart rate will begin to decrease.
if blood entering the heart gets mixed with blood leaving the heart the the blood leaving the heart will get poluted. the blood entering the heart is poluted when it enters the heart, the heart cleans it up; so when the blood leaves the heart it is clean so if it gets polluted the person may get sick and this leads to his/her death.

The blood entering from the lungs has a high oxygen content and the blood entering from the body is high in carbon dioxide.
Blood entering the heart from Superior vena cava and Inferior vena cava is "dirty". Bloold going through Pulmonary artery is 'dirty" and is "cleaned" (oxygenated) in the lungs. Blood entering the heart via pulmonary vein and leaving via aorta is clean.
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
Four main blood vessels enter/exit the heart: two veins and two arteries. Oxygenated blood enters the left ventricle through the pulmonary vein. This same blood is then pumped out of the left atrium via the aorta. Meanwhile, de-oxygenated blood enters the heart in the vena cava; before leaving through the pulmonary artery.
When talking about the right or flight response in regards to the the vasoconstriction of blood vessels entering and leaving the heart, the biological advantage is having your heart ready and your muscles ready for anything. As for the conversion of glycogen to glucose, this is referring to the energy your body uses.

As blood leaves the heart it travels through the arteries. The first one will be either the pulmonary artery (for blood leaving the right side of the heart) or the aorta (for blood leaving the left side of the heart).
