O2 poor. Pulmonary veins carry O2 rich blood.
CO2 and O2
a pulmonary artieriole is part of the respiratory system. inside the respiratory system is an organ called alveoli and the alveoli are covered in a network of capillary. the job of the pulmonary arteriole is to carry deoxygenated blood into the capillary network.
Not always. The pulmonary artery and the pulmonary vein reverse the general roles of O2 rich and poor blood. The pulmonary artery carries O2 poor blood to the lungs and the pulmonary vein carries O2 rich blood back to the heart in order to be sent to the rest of the body.
Gasses are exchanged (CO2 is lost & O2 is gained).
The O2 Academy Leeds has a capacity of around 2,300 people.
Yes, in children also. The pulmonary veins carry oxygen rich blood from the lungs to the heart.
o2 poor blood
If I'm not wrong, the O2 is carried from your lungs by red blood cells, then is passed to the muscles which need it through the walls of the blood vessels, while they take CO2 from the muscles to bring it back to the lungs to expel. So... it occurs through the bloodstream and the walls of the blood vessels (capillary vessels etc.)
That depends on whether you are asking about the red blood cells themselves, or the blood as a whole. The fluid portion of the blood will have a O2 partial pressure around 20%, but the red blood cells will have an O2 partial pressure nearing 100%.
The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
The molecular formula of 'normal' oxygen is O2, indicating that it consists of two oxygen atoms chemically bonded together.
