What else can I help you with?
How many layers of cells does oxygen diffuse through before it reaches a red blood cell?
Oxygen diffuses through two layers of cells: the alveolar epithelial cells lining the lung air sacs and the capillary endothelial cells before it reaches a red blood cell in the pulmonary capillaries.
What is a human lung cell eukaryote?
collects oxygen
Does the lung bring oxygen into the body?
Yes. The blood passes through the lung tissues and gets oxygen.
How does oxygen pass through a lung cell Diffusion?
Oxygen passes through lung cells primarily by diffusion, a process driven by the concentration gradient. When oxygen levels in the alveoli (air sacs in the lungs) are higher than in the blood, oxygen molecules move from the alveoli into the lung cells and then into the bloodstream. This movement occurs across the thin alveolar and capillary membranes, allowing oxygen to enter red blood cells for transport throughout the body. The efficiency of this process is enhanced by the large surface area of the alveoli and the thinness of the respiratory membranes.
What goes to the lungs then to the cell?
Carbon dioxide, Waste product, goes from the cell to the lungs. So the question is lung to the cell, not positive, but oxygen.
How is oxygen transported from the lungs to the body cell?
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
How does the heart pump blood to the lungs via the pulmonary artery to take up oxygen from the inspired air and at the same time releasing the waste product of 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.
What does a red blood cell have that enables it to perform its function optimally?
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.
Alveoli are very effective in promoting the rapid exchange of oxygen and carbon dioxide between blood circulating through the lung capillaries?
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 ?
The essential cell of the lung?
not sure if this is what you are looking for, but alveoli are grape like clusters that absorb oxygen. Hope it helps!
What is the plura lining the thoracic cavity?
a plura surrounds each lung, with a gap between the plura and the lung.
Parietal pleura is a serous membrane where?
the inner lining of the lung
