muscle gaining secrets - muscle maximizer

The circuit, which means the heart, blood vessels and

lymphatics, together with the blood

body transport.

The system transports various substances around

in the organism, it is an important factor in the body

defense against infection and foreign substances,

it also acts as a heat distribution.

blood circuit

The circuit consists of blood vessels in various

sizes, as well as a muscle pump - the heart.

From heart kept blood into the arteries, which is

blood vessels with relatively thick walls.

The arteries divide into smaller and smaller

branches, so that the blood finally through small

arteries are distributed to all cells in the entire

body.

These small arteries, arterioles, and is called the

0.1 mm in diameter. They contain a layer of

smooth muscle gaining secrets inf0, which controls the blood vessel

diameter, and hence the blood pressure.

From the arterioles blood passes into a large

network of capillaries. These are very small,

less than 0.01 mm in diameter. In all tissues, there is a

large number of capillaries. We have calculated the

total length of the capillaries in the

human organism to be approx.

100.000 km (This is equivalent to a trip 2 1/2 times

around the earth). The inner surface is

approx. 5000 m2

or as a football field.

Capillary walls is only one cell layer thick.

This means that the liquid, dissolved substances and

gases exchanged easily between the blood and the

adjacent cells.

The blood is collected again after it has delivered oxygen

and nutrients in the small veins called venules,

which in turn is assembled into larger veins. The blood is sent

from here back to the heart through a few large

veins.

Other wall consists of a smooth inner exercises, a layer of

of muscles not under voluntary control

and an outer connective tissue layer. veins contain

valves, which ensure that the blood can flow only in

direction back toward the heart.
