What else can I help you with?
Which structures connect the arteries and veins?
a large network of capilleries.
Is the artery the same size as your vein?
Arteries and veins can be different sizes, because large arteries branch into smaller arteries, which branch into capillaries. These capillaries branch into small veins, which branch into large veins. So yes, they can be (and usually are) the same size if (I am surmising this) they are the same distance from the capillaries.
Is a capillary an artery?
No, capillaries are not arteries. Capillaries very tiny vessels where food, waste, and gasses are transferred between the cells and blood. Arteries are large to moderate sized vessels that deliver blood from the heart to the capillaries.
The difference between continuous capillaries and fenestrated capillaries?
Continous capillaries contain tight junctions and are less "leaky " than fenestrated capillaries. They only allow the movement of water and small ions, whereas fenestrated capillaries contain many fenestrae or pores and allow many molecules with the exception of medium and large proteins to pass
What nephron structures are involved with absorption?
The small and large intestines. The small intestine contains blood capillaries and lymph vessels.
How can capillaries allow gas exchange?
Capillaries have thin walls that allow for diffusion of gases such as oxygen and carbon dioxide between the blood in the capillary and surrounding tissues. The close proximity of capillaries to cells ensures efficient exchange of gases due to a short diffusion distance. Additionally, the high surface area of capillaries facilitates a large area for gas exchange to occur.
Why is capillaries narrow?
Capillaries are very small in size because they need to have a large surface area so they are able to transport blood all around the body. Blood cells must pass in single file through the capillaries as they are so small.
Fenestrated capillaries have?
Pores (fenestrae) through the cells that allows the passage of large molecules such as protiens.
What does hemangioma mean?
It is an abnormally large bed of capillaries. They are usually harmless but occassionally cancause problems if they are very large or located in a troublesome place.
Why capillaries very small in size?
Capillaries are very small in size because they need to have a large surface area so they are able to transport blood all around the body. Blood cells must pass in single file through the capillaries as they are so small.
Why the tissue fluid can escape from capillaries but the erythrocytes can not?
The escape of tissue fluid from the capillaries occurs through small gaps present in the walls of the capillaries.These gaps are quite big so as to allow the passage of fairly large molecules but are not large enough to allow the escape of erythrocytes.
Capillaries that have a incomplete lining are called?
continuous capillaries continuous capillaries
