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.

Your capillaries are AMAZINGLY thing,
when you start to bleed or graze your knee, even if you get a paper cut then that means one of your cappillaries has burst.
If excess tissue fluid does not return to the capillary where does it go?
Your mom who is in my bedroom ;)
The capillary bed that surrounds the descending and ascending loop of Henle is called the?
Is drained by an efferent arteriole.
Which are 2 waste product found in capillaries?
Carbon dioxide is one of them, i am uncertain about the other.
The capillaries inside bowman's capsules are the?
the capillaries inside the Bowman's capsules are called the?
How are arterioles capillaries and venules related?
Arterioles are the small arteries that lead into the capillaries, which connect to cells in the body. Venules are the small veins that the capillaries flow back into, leaving the cells.
Why must capillaries have a greater surface area to volume ratio compared to arteries?
Capillaries are tiny blood vessels. They need to have a greater surface area to volume ratio because they need to diffuse oxygen quicker.
When intestinal walls are overstimulated making it different for waste to pass thin is called?
Diverticulitis
diffusion
Why do capillaries have such thin walls?
Capillaries have thin walls to optimise the level of diffusion of oxygen and other nutrients in the blood stream to the surrounding cells.
Contrast the direction of movement of oxygen in lung capillaries and other capillaries in the body?
the direction of movement of oxygen from the air you breathe and to dispose of excess.
Does blood move more rapidly or less rapidly after it flows from the capillaries into a vein?
more rapidly, in the capillaries the blood cells flow in "single file". In the veins, multiple cells are allowed to pass at once
Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.
What is secrete into capillaries that run through each endocrine glands?
They are known as the exocrine or duct glands
What is the is the job capillaries?
A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active. For example, muscle tissues and the kidneys have a greater amount of capillary networks than do connective tissues.
The pulmonary vein carries OXYGENATED blood from the lungs, where it has become oxygenated, to the atrium of the heart
What are the features of a capillary cell that makes it good at its job?
Thin cell wall - facilitates permeability of gases and blood. High surface-to-volume ratio
