Circulatory System

consists of organs and fluids that transport materials across the body

artery/arteries

semi-elastic vessels that transport blood away from the heart

Vein

capillary/capillaries

smallest and most numerous of blood vessels

Pulmonary Circulation

Circult that provides body flow from the heart to the lungs

Systemic Circulation

circult that allows blood to flow from the heart to the rest of the body. excluding the lungs

Plasma

protein rich fluid that carries waste, gases, and nutrients.

Blood Pressure

The force of blood pushing against the walls of the blood vessels.

Aorta

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

Superior and Inferior Vena Cava

The two largest veins in the body.

Artierioles

Branch off/Small arteries.

Venules

Small veins.

Right and Left Atrium

The two upper chambers of the heart.

Right and Left Ventricles

The two lower chambers of the heart.

Valves

Is in between each atrium and ventricle to prevent the blood from flowing backwards

Red Blood Cells

Cells that transport oxygen molecules to every cell of the body and they get the color from hemoglobin

White Blood Cells

Cells that fight and destroy germs and illnesses in the body.

Platelets

Blood cells that help our blood to clot.

Hemoglobin

complex protein made up of four protein strands, plus iron-rich, hemegroups

Transport oxygen and carbon dioxide

Disease protection and healing

Regulate body temperature

Functions of the circulatory system

Oxygenated and Deoxygenated blood

2 types of blood

Oxygenated blood

type of blood that contains nutrients and oxygen and found in arteries

Deoxygenated blood

type of blood that is low in oxygen

Blood

it carries the materials throughout the body

Right atrium, Left atrium, Right Ventricle, Left Ventricle

These are the four chambers of heart

Atria

The receiving chambers of the heart, accepting blood from the body and the lungs

Ventricles

the pumping chambers of the heart moving blood to the lungs and into the body

coronary circulation

circuit that provides blood to the tissues of the heart
