Structure of Cardiovascular
The blood
Blood Vessels
Arteries and vein of the face, head and neck
Lymphatic system
100

Thick membrane that encases the heart, which contracts and relaxes to force blood to move through out the system.

Pericardium

100

sticky, salty fluid that circulates through the body, bringing nourishment and oxygen to all parts of the body. 

Blood

100

Tubular, elastic, thick-walled branching vessels that carry oxygenated blood from the heart to all the tissues of the body.

Arteries

100

splits into the internal and external carotid arteries; supplies blood to the head, face and neck. 

Common Carotid Artery (CCA)

100

bean shaped structures that filter out bacteria and viruses from the lymph fluid.

Lymph Nodes

200
Thick muscular middle layer between pericardium and endocardium

Myocardium

200

AKA Red blood cells. Uses hemoglobin to transport oxygen. Hemoglobin attracts oxygen molecules.

Erythrocytes

200

Tubular, elastic, thin-walled branching vessels that carry deoxygenated blood from the capillaries in the tissues back to the heart and lungs for cleaning and to pick up oxygen.

Veins

200

Returns all blood from the head, face and neck to the heart. 

Internal Jugular Vein

200

A colorless fluid, rich in WBC that attack bacteria in the blood. 

Lymphatic Fluid 

300

Thin inner lining.

Endocardium

300

AKA White blood cells. Fight bacteria and other foreign substances. 

Leukocytes

300

Tiny, thin-walled vessels that connect the smaller arteries to venules. 

Capillaries

300

Branch of the External Carotid Artery; supplies blood to the back of the head and up the crown.

Occipital Artery

300

Lymphocyte-rich tissue that makes up the spleen, thymus, lymph nodes, tonsils and adenoids.

Lymphatic tissue
400

Upper chambers (2) of the heart

atrium

400

AKA blood platelets. These are responsible for clotting of blood.

Thrombocytes

400

Part of the arteries that are smaller and deliver blood to capillaries.

Arterioles

400

Branch of the ECA; supplies blood to the scalp, above and behind the ears. 

Posterior Auricular Artery

400

Thin tubes shaped like blood vessels that carry lymph fluids and WBC within the lymphatic system. 

Lymphatic vessels

500

Lower chambers (2) of the heart.

Ventricle

500

Fluid part of blood which red and white blood cells and blood platelets are suspended.

Plasma

500

Small-diameter blood vessels that receive blood back from the capillaries. 

Venules

500

Branch of ECA; branches into smaller arteries; supplies blood to sides and top of head 

Superficial Temporal Artery

500

Between cells, these closed ended capillaries drain extracellular fluid.

Lymphatic capillaries
