Major Arteries & Veins

Pulmonary

Refers to circulation thats carryings oxygen poor blood from the right ventricle to the lungs.

Cornonary Arteries

Blood vessels that supply blood carrying oxygen and nutrients to the myocardium of the heart.

Pulmonary Vein

The vein that carries blood from the lungs to the heart. It is the only vein that carries oxygenated blood.

Hepatic Vein

The vein that carries blood away (drains) from the liver.

Carotid Artery

Refering to the common carotid artery supplies blood to the head and face.

Pulmonary Artery

The blood vessel that carries blood from the from the right ventricle to the lungs. It is the only artery that carries deoxygenated blood.

Cappillaries

The smallests (microscopic) of blood vessels (one cell layer thick) that are the site of gas, nutirent, and waste exchange between cells and the blood. They also connect arterioles to venules.

Internal Carotid Artery

Artery that supplies blood to the brain.

Inferior Vena Cava

Carries (drains) blood from the lower limbs of the body and empties in the right artium.

Vertebral Artery

Supplies blood to the spinal column and brain.

Great Saphenous Vein

The longest vein in the body. Sometimes used in bypass surgery.

Venules

The smallest of veins that receive blood from capillaries.

Right Atrium

Receives deoxygenated blood from the body via the superior and inferior vena cava.

Brachiocephalic

Artery or vein that services right arm, head, and shoulder.

Left Ventricle

Chamber that pumps oxygenated blood out to the body.

Veins

Blood vessels that carry blood back to the heart. Veins also have valves to prevent back flow.

Arterioles

Blood vessels that are smaller branches off of arteries.

External Iliac

Artery or vein that services the groin and lower leg.

Systemic

Refers to circulation that carries oxygen rich blood from the left ventricle to the body.

Portal System

System of veins that carry blood from the abdominal organs to the liver.

Subclavian Artery

Both a left and right, blood vessels that supply blood to the shoulders and upper limbs.

Left Atrium

Chamber that receives oxygenated blood from the pulmonary veins and pumps it into systemic circulation.

Superior Vena Cava

Carries (drains) blood from the head, neck, and upper limbs and empties in the right atrium.

Mesenteric arteries

originate on the aorta; superior under renal artery,

inferior under gonadal artery

What are the layers of veins and arteries

Tunica Intima
Tunica Media
Tunica Adventitia

Tunica Intima

The most inner layer of veins and arteries
Consist of squamous endothelium
smooth muscle
secrete vasocontrictor
secrete vasodialator

Tunica Media

Middle Layer
Consist of smooth muscle
Collagen
Elastic Tissue

Tunica Adventitia

Most Outer Layer
Has Loose Connective Tissue

Myocardium

Middle Layer of Heart Wall
Contains Muscle Tissue
Forms atria and ventricles
blood vessels
nerves

Endocardium

Inner layer of the heart
consist of simple squamous epithelium
areolar tissue

Parietal pericardium

Outer covering of the heart
Consist of fibrous tissue
