They are part of the cardiovascular system.
pulmonary vein and systemic veins
The Right Atrium of the heart receives blood from the systemic veins.
True.
carry deoxygenated blood to the heart
In pulmonary arteries, PO2 is around 40 mmHg and PCO2 is around 46 mmHg. In pulmonary veins, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic arteries, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic veins, PO2 is around 40 mmHg and PCO2 is around 46 mmHg.
The right atrium.
There are four main types of veins that pigs and humans have in common. These include the pulmonary, systemic, deep, and superficial veins.
The veins carry blood to the heart from the lungs and the body.
The systemic arteriole, then the capillaries, the venule, the vein, the vena cava, the heart, the pulmonary artery, the pulmonary arterioles, capillaries, the pulmonary veins, the heart, into the aorta, and back into the artery.
FROM THE LUNGS Ans 2: Veins have valves that cause one-way flow of blood. Muscular contraction squeezes the veins and causes the veins to pump blood back towards the heart.
Systemic Circulation
yes - it means that they store/hold a lot of blood.
