The Arteries

The Circle of Willis

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.

lymphatic system
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
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
