The Arteries
Circle of Willis - also called
the cerebral arterial circle this
structure surrounds the
pituitary gland and optic
chiasma. It connects the
anterior and posterior blood
supply to the brain. It also
equalizes blood pressure in
the two brain regions and
provides alternate routes for
blood to reach the brain
tissue in case of blockage to
the carotid or vertebral
arteries.

- Are arteries that when
compressed can stop
blood flow into distal
tissues during
hemorrhage.

Lymphatic System



Lymph – Protein containing fluid transported
by lymphatic vessels.
Lymphatics – an elaborate system of drainage
vessels that collect the excess protein-containing
interstitial fluid and return it to the bloodstream.
Lymph Node – a small lyphoid organ that
filters lymph; they contain macrophages and
lymphocytes.

Spirometry
Tidal Volume – The amount of air that moves into then
out of the lungs during normal quiet breathing.
Vital Capacity – The total amount of exchangeable air in
the lungs. Or the total amount of air blown out during
one forced exhalation.
There are 3 factors which influence vital capacity:
1.) Age
2.) Sex
3.) height
