Oxygenated blood travels from the lungs through the pulmonary veins into the left side of heart, which pumps blood into the body. Good luck hope this helps ;)
Nucleus
collects oxygen
Yes. The blood passes through the lung tissues and gets oxygen.
The red cells in blood pick up the oxygen molecule from the lung surface cells and take it all over the body through the vascular system and depsoit it where needed
Carbon dioxide, Waste product, goes from the cell to the lungs. So the question is lung to the cell, not positive, but oxygen.
A red blood cell's job is to transport oxygen to lung tissue and get rid of waste such as carbon dioxide. It is adapted to its job as it has no nucleus and no liquids inside it, so there's more space for oxygen to be transported to lung tissue and for waste to be collected.
vains pass through the outer layer of the lung and the oxygen (being soluble) passes through and oxygenates the blood
The oxygen enters the body via the nose and mouth then travels down the trachea ( wind pipe ) then breaks into two bronchi (the bronchi splits the air into each lung) which then branches into lots of bronchioles which end in lots of alvioli.
In animals: The lungs... they inhale Oxygen, which then passes into the bloodstream, through tiny capillaries in the lung lining.Some blood flowing through the lung lining has excess carbon dioxide, which is passed through to the lungs and exhaled. In plants: carbon dioxide is absorbed through small openings called stomata. During the day photosynthesis uses it in combination with sunlight to produce energy. At night, without sunlight, the process is, sort-of, reversed, and the stomata release carbon-dioxide.
Both oxygen and carbon dioxide cross the thin lining of the alveolus. Oxygen crosses from inside the lung into the blood and carbon dioxide crosses from the blood into the lung to be exhaled.
Yes, 93 %. The only thing missing was "exchange of O2 and CO2 between" what and what ? For example, O2, transported via haemoglobin to the alveoli, gets transferred to the target [tissues] cells by passage (small molecules by diffusion) through the epithelial lining - which is generally one epithelial cell layer thick as found in the capillaries of the lung. Is the CO2 removal process similar or dissimilar to the O2 delivery system ?
not sure if this is what you are looking for, but alveoli are grape like clusters that absorb oxygen. Hope it helps!
a plura surrounds each lung, with a gap between the plura and the lung.
