Is blood transported through the alveolis?
No, blood does not travel through the alveoli. There is however a dense blood capillary network surrounding the alveoli.
Do veins have the ability to go through vasoconstriction and vasodilation?
Yes, the veins have the ability to go through the vasoconstriction and vasodilation. This also applies to the other elastic tubular channels like the capillary and the arteries.
How is blood supplied in the chest cavity?
Through capillary beds surrounding the walls and alvoli in the lungs; the 'cavity' contains no blood as it is gas filled
What is different about the capillary exchanges seen in a capillary with fenestrations and intercellular clefts and the exchanges seen in a capillary lacking those modifications?
Capillaries with fenestrations and intercellular clefts allow for different diffusion of substances depending on structural characteristics (and permeability) of the capillary. Fenestrated capillaries are found where absorption are a priority, such as the intestines or endocrine glands, or where filtration occurs, such as the kidneys. A fenestra is an oval pore covered (usually) by a delicate membrane, and is much more permeable than a plain plasma membrane. Intercellular clefts are gaps in the plasma membrane, or areas not joined tightly, and are another way substances can enter the cell. Almost all capillaries have these. Substances can diffuse directly through the plasma membranes of cells only if the substances are lipid-soluble (like the respiratory gases), and certain lipid-insoluble substances can enter or leave the blood by passing through the plasma membranes of endothelial cells within vesicles, by endo or exocytosis.
How does the capillary help substanances pass through it?
Slow flow speed in the capillary increases the efficiency of diffusion. In addition, the thin wall of the capillary helps substances to pass through efficiently.
What is the explanation for the process of capillary exchange?
Capillary exchange is the process by which substances, such as oxygen and nutrients, are exchanged between the blood in capillaries and the surrounding tissues. This occurs through diffusion, facilitated diffusion, and active transport. The exchange is driven by a concentration gradient and the movement of substances across the capillary wall is regulated by small pores called fenestrations and by the presence of transport proteins.
The movement of a gas into moist intercellular spaces through stomates is an adaptation for respiration in?
Plants.
What can squeeze themselves through capillary walls?
neutrophils
What is water forced through capillary walls by?
Osmosis
What is the movement of leukocytes through capillary walls?
diapedesis
Tiny vessels through which diffusion take place between the blood and the body tissues?
capillarycapillaries
What sentence could you use for the word capillary action?
Water is transferred from the roots to the leaves through the stem by capillary action.
