30 paź 2023 · The pulmonary veins are large valveless vessels that carry oxygen-rich blood from the lungs to the left atrium of the heart. These veins are unique in that, unlike other veins of the body which transport deoxygenated blood, the pulmonary veins carry oxygenated blood.
16 cze 2020 · As blood leaves the lungs through the pulmonary veins, the venous \(\text{P}_{\text{O}_2}\)= 100 mm Hg, whereas the venous \(\text{P}_{\text{CO}_2}\)= 40 mm Hg. As blood enters the systemic capillaries, the blood will lose oxygen and gain carbon dioxide because of the pressure difference of the tissues and blood.
Oxygenated hemoglobin is red, causing the overall appearance of bright red oxygenated blood, which returns to the heart through the pulmonary veins. Carbon dioxide is released in the opposite direction of oxygen, from the blood to the alveoli.
