through the lungs and to be supplied with oxygen.

Systemic circulation-✔✔ Takes oxygenated blood from the heart to the
body and then back to the heart.

Cardiac circulation-✔✔ Blood circulation throughout the heart.

Atria-✔✔ Collecting chambers. Receives blood from lungs and body,
pump it into ventricles. Right side receives deoxygenated blood from the
body. Left side receives oxygenated blood from the lungs.

Ventricles-✔✔ Thick, muscular chambers that pump blood away from the
heart. Right side pumps deoxygenated blood to the lungs. Left side pumps
blood to the body.

Bicuspid valve-✔✔ Regulates flow between left atria and left ventricle.

Tricuspid valve-✔✔ Regulates flow between right atria and the right
ventricle.

Aortic valve-✔✔ Regulates flow from the left ventricle into the aorta.

Aorta-✔✔ Largest artery of the body. Carries blood from the heart to the
rest of the body.

Septum-✔✔ Muscular wall of the heart that divides it into two halves.

connective tissue and elastic fibers. Middle – smooth muscle and elastic
fibers. Inner – single layer of epithelial cells used to reduce friction.

known as venules. Contain the same three structural layers as arteries.
Layers are thinner and more flexible.

Capillaries-✔✔ Incredibly small blood vessels that connect the circulatory
system to body tissues. Site of nutrient, gas, and waste exchange. Are one
cell layer thick with an average diameter 8 μm. Small size allows for the
diffusion of nutrients, gas, and wastes.

Sinoatrial node-✔✔ The pacemaker, stimulates both atria by producing an
electrical impulse.

Atrioventricular node-✔✔ Transmits the impulse, causing the two
ventricles to contract.

Plasma-✔✔ Fluid portion of blood. Carries blood cells, nutrients, and
wastes. Clear fluid composed of water, dissolved substances, and proteins.
Has several functions

Red blood cells-✔✔ Erythrocytes. On average, people have between 4.5 –
5.5 million per milliliter of blood. Are specialized for oxygen transport.
Oxygen transport made possible by hemoglobin. Is 45% of our total
blood's volume.
