Blood pressure depends on cardiac output and vascular resistance.
It is usually measured in arteries.

Platelets adhere to damaged vessels and aggregate.
They also support coagulation reactions.

Arteries have thick elastic walls suited to higher pressure.
Their oxygen content depends on the circulation involved.

The left ventricle ejects blood into the aorta.
Its thick wall generates systemic pressure.

Hemoglobin binds oxygen in red blood cells.
It also contributes to carbon-dioxide transport and buffering.

Red blood cells contain hemoglobin.
Their biconcave shape supports gas exchange.
