Capillaries
The smallest vessels in the circulatory system that are located within the tissues of the body, they transfer blood from the arteries, through the tissues to drop of nutrients and pick up waste and back to the veins.

How it is possible to bypass capillary by shunting blood directly from arteriole to venules?
this is possible because there are alternate branches that bypass capillary beds.
What system are capillaries in?
The circulatory system, responsible for distributing nutrients in blood through the entire body. Capillaries are the smallest blood-carrying "tube" in the body.
Please note that every system in the human body is directly related to one or more other systems. Capillaries also work with the Respiratory system in which they carry oxygen and carbon dioxide to trade with cells.
it will be too low
Why is there a large amount of blood capillaries in lungs digestive system and muscles?
There are many capillaries in your lungs, digestive system and muscles because each of these locations require blood to be transfered to individual cells snd capillaries are the smallest vessels that can do this.
In your lungs capillaries connect to the alveoli and enable gas exchange within the body.
In your digestive system capillaries enables food to be passed through the walls of the intestines.
In your muscles capillaries deliver a fresh supply of oxygen to each cell and remove any bi-products enabling you to move sufficiently.
Capillaries exchange food, oxygen, and carbon dioxide.
How does the structure of the capillaries help diffusion occur fast enough to keep you alive?
The structure of capillaries help diffusion occur fast enough to keep you alive by the nutrients and gases occurs in these specialized blood vessels which are between arteries and veins.
Convolute means making a story complex and hard to follow.
What is the role of the cells that line the capillaries of the brain?
The cells lining the brain's tiny blood vessels (capillaries) are specifically designed to prevent many substances from passing into brain tissue.
false
membranes and osmosis pressures
Why do substances tend to leave the bloodstream at the arterial end of the capillary?
to ignorant to answer
What is the function of the capillaries in the dermis?
Every cell in your body has a capillary run by it. This capillary delivers nutrients and oxygen and removes waste and carbon dioxide.
Why must capillary be so thin?
Capillery walls need to be thin so oxygen, nutrients and otherthings including hormones can diffuse into cells, also thin capilleries are needed for waste products such as carbon dioxide and urea to diffuse out of cells.
What is the usage of capillary viscometer?
A Capilliary Viscometer measures the speed at which a lquid can be forced through a narrow tube (a capillary). Thicker liquids (high viscosity like treacle) will take a lot longer to squeeze through the tube than a thin liquid (like white spirit). If you take a fluid (liquid) like blood it could be put through a Viscometer like this to see if your blood was too thick or thin. Also it could be used to check if your engine oil met up to spec.

What happen to the speed of blood as it flows through the capillaries?
This isn't a definite answer but blood probably goes slower when it travels through capillaries, this is probably because it is basically being filtered.
