Heart

These are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide, and other waste products to pass to and from our organ's cells.

Capillaries.

apex

pointed end of the heart

SA node (pacemaker) 1st

starts the sequence by causing the atrial muscles to contract.

5th

Purkinje fibers (causing it to contract)

The main components of the cardiac conduction system are the

SA node, AV node, bundle of His, bundle branches, and Purkinje fibers.

TRICUSPID/BICUSPID

Aorta

The largest artery in the body; it conducts freshly oxygenated blood from the heart to the tissues. LEFT VENTRICLE

Veins.

These are blood vessels that take blood back to the heart; this blood lacks oxygen (oxygen-poor) and is rich in waste products that are to be excreted or removed from the body. Veins become larger and larger as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.

Arteries.

They begin with the aorta, the large artery leaving the heart. Arteries carry oxygen-rich blood away from the heart to all of the body's tissues. They branch several times, becoming smaller and smaller as they carry blood farther from the heart.
