What else can I help you with?
What is the mechanism that allows oxygen to move from the alveolar into the pulmonary capillary blood?
Simple diffusion
What is a pulmonary arteriole?
A pulmonary arteriole is a small blood vessel that carries oxygen-poor blood from the right side of the heart to the lungs for oxygenation. These arterioles are part of the pulmonary circulation system that helps exchange carbon dioxide for oxygen in the blood.
What type of blood does a capillary usually carry oxgen rich or poor blood?
The pulmonary artery is the blood vessel that leads away from the heart (Artery=Away), toward the lungs. It is pumping blood to that lungs that just returned from the body (via the vena cava, into the right atrium). So the blood in the pulmonary artery has the lowest concentration of O2 and the highest concentration of CO2. It is just about to pick up lots of oxygen, once it gets to the lungs.

When blood within the pulmonary capillary network is oxygenated it travels to the heart via which structure?
It comes back through the pulmonary veins. Veins always carry blood TO the heart. This is the only case where veins are high in oxygen.
Where does an artery carry oxygen poor blood?
The pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood.
What is the exchange of gases between the alveolar air and pulmonary capilaary blood?
The exchange of gases between the alveolar air and pulmonary capillary blood is called pulmonary gas exchange. Oxygen diffuses from the alveoli into the capillaries, while carbon dioxide diffuses from the capillaries into the alveoli. This process is essential for the body to obtain oxygen and release carbon dioxide.
What way does oxygen move during pulmonary gas exchange?
During pulmonary gas exchange, oxygen moves from the alveoli in the lungs into the bloodstream. This process occurs due to the difference in partial pressure; oxygen has a higher concentration in the alveoli than in the deoxygenated blood in the pulmonary capillaries. As a result, oxygen diffuses across the alveolar-capillary membrane into the blood, where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
Which pulmonary blood vessels carry oxygen-rich blood?
The pulmonary veins carries oxygen rich blood from the lungs to the heart.
What does a pulmonary artery carry that a pulmonary vein doesn't?
The pulmonary artery carries oxygen-poor blood. The pulmonary vein carries oxygen-rich blood.
What is the type of transport that oxygen move from the alveoli into the pulmonary capillary blood?
Oxygen diffuses from the alveoli into the blood due to higher PO2 (partial pressure of oxygen) levels in the alveoli than in the blood.
Exchange of gases between alveolar air and pulmonary capillary blood?
Oxygen passes from the air sacs in the lungs to the blood in the capillaries, carbon dioxide passes the other way.
