What vessels exchange materials with the extra cellular fluid and the blood?
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
What does the free exchange of ideas between scientific fields allow?
Valuable principals and approaches that have been laboriously gleened from one field to hasten the progress in another.
Why are air spaces near most of the stomata?
provides space for gas exchange, to allow CO2 in and O2 out.
What happen to air pressure when air is cooled?
The molecules of a gaseous form slow down, thus shrinking in volume. As you know, molecules/atoms are in constant motion, and with temperature fluctuations, they either slow down, and compress, or they increase in speed and expand. Ever notice that tires seem a bit flat in the winter? Or bridges have little gaps to allow room to expand in summer months, as well as for when they "shrink" in cooler temperatures the overall structure is not corrupted.
Which sediment will allow water to pass through most easily?
sediments made of larger particles will have larger spaces between them, and thus allow greater fluid flow.
What is the work of capillaries?
allow gaseous exchange
What is the work of the capillaries?
allow gaseous exchange
What duty do the lungs perform?
They allow gaseous exchange between the inhaled oxygen and the exhaled carbon dioxide.
Do stroma allow exchange of gases such as carbon dioxide and oxygen between the plant and the atmosphere?
No
What is the function of stomata in a leaf?
Stomata are small pores in the underside of leaves. The primary function is to allow gaseous exchange between the plant's internal tissues and the atmosphere. Oxygen and water vapour (byproducts of photosynthesis) are released from the open stomata into the atmosphere; carbon dioxide present in the atmosphere is allowed to enter the stoma (this is required for photosynthesis.
How are the lungs and the capillaries connected?
The lungs contain air sacs called alveoli which are surrounded by blood capillaries to allow gaseous exchange.
The epidermis of a herbaceous stem has small openings called that allow gas exchange between the tissues inside the stem and the atmosphere.?

How do euglena do cellular respiration?
Eugena does not breathe in the sense that animals do. However, it does perform photosynthesis, which helps allow for the exchange of gases. Also, the permeable membrane surrounding the euglena allows for gaseous exchange.
Does arteries allow for the exchange of gases between the blood and body cells?
capillaries
Allow the exchange of gases between the environment and the air spaces inside the leaf?
Stomata
What three methods allow exchange of molecules between cells and their surroundings?
Diffusion- Osmosis Endocytosis
What is avieoli?
they are tiny air sacs in the lungs that allow the exchange between oxygen and carbon dioxide.
