Physiology of theCirculatory System
2 components: Systemic & Pulmonary Circulation
A video to watch: https://www.youtube.com/watch?v=NJzJKvkWWDc
Pulmonary path to the lungs
• Releases CO2 in blood blood receives oxygen
2) Goes to pulmonary arteries
3) Smaller arteries
4) Arterioles
5) Pulmonary capillaries that surround alveolus
1) Start in right ventricle
10)left atrium
9)Pulmonary veins
Pulmonary path from the lungs
6)capillaries
7)venules
8)veins
Red blood cells exchange gases in the lungs
Gas Exchange
Release Co2 and receive O2
2
Systemic Pathwayoxygen to cells cells release
waste
9)right atrium
8)vena cava
1)left ventricle
2) aorta
7)veins
3)Smaller arteries
4)arterioles 6)venules
5)capillaries 5)capillaries
capillaries
Releases O2 receives CO2cells of organs

Blood Circulation1)Atria empties its blood into the ventricles
2)Ventricles push blood towards the body &lungs
- blood pressure is at its minimum: diastolic
Blood Pressure
- Pressure where blood is pushed against arteries
pressure- blood pressure maximum: ventricle systole
High Blood PressureAbnormal increase of pressure in
the artery walls- Could tear the heart and damage arteries- Could be temporarycauses: diet, stress, tobacco and alcohol
Coronary Bypass
Vein is removed from another part
of the body.
Result: blood bypasses around
blocked artery
Arterial Endoprosthesis
Small spring inserted in the arteries for blood circulation
Angioplasty: introduction through the groin or arm smaller than coronary bypass
