Circulatory Pathways: Pulmonary and Systemic Circulation

Pulmonary Circulation

Blood flow from heart to lungs and back.

Systemic Circulation

Blood flow from heart to body and back.

Right Atrium

Collects deoxygenated blood from the body.

Right Ventricle

Pumps deoxygenated blood to pulmonary trunk.

Pulmonary Trunk

Short vessel carrying blood to lungs.

Pulmonary Arteries

Transport oxygen-poor blood to lungs.

Pulmonary Capillaries

Site of gas exchange in lungs.

Pulmonary Veins

Carry oxygen-rich blood to left atrium.

Left Atrium

Receives oxygenated blood from pulmonary veins.

Left Ventricle

Pumps oxygenated blood into the aorta.

Aorta

Major artery distributing blood to body.

Coronary Circulation

Blood supply to heart muscle itself.

Coronary Occlusion

Blockage of coronary arteries, reducing blood flow.

Atherosclerotic Plaque

Build-up in arteries, leading to occlusion.

Thrombus

Blood clot that can obstruct blood flow.

Major Vessels

Key arteries and veins in circulation.

Oxygenation

Process of adding oxygen to blood.

Deoxygenated Blood

Blood low in oxygen, high in CO2.

Oxygenated Blood

Blood rich in oxygen, low in CO2.

Capillary Networks

Tiny blood vessels facilitating nutrient exchange.

Venous System

Returns deoxygenated blood to the heart.

Blood Flow Order

Sequence of blood movement through heart and lungs.
