this structure regulates heart rate locally.
the SA node (or the pace maker)
this part of the blood is 90% water
the plasma
this vessel brings blood back to the heart from the lungs
pulmonary veins
This system works with the cardiovascular system to deliver nutrients to the body
the digestive system
The protective lining that surrounds the heart
the pericardium
These areas make up each of the two upper cavities of the heart
the atria
this part of the blood is responsible for stopping blood loss and clotting
the platelets
These tiny blood vessels connecting arteries to veins and carry oxygen and nutrients to individual cells throughout the body.
the capillaries
this system filters the blood and removes wastes, keeping a person healthy.
the urinary system
this muscular tissue that makes up the wall of the heart
the myocardium
each of the two lower cavities of the heart
the ventricles
This is a colorless fluid containing white blood cells, which bathes the tissues and drains into the veins
the lymph
These large blood vessels deliver oxygen-rich blood from the heart to the tissues of the body
the arteries
this organ is the primary filter for your blood in the urinary system
the kidney
this is a red protein responsible for transporting oxygen in the blood of vertebrates; contains iron
hemoglobin
The specialized structures work to ensure blood only flows in one direction through the heart
the valves
this is the cellular component of blood that helps defend the body against infection
the white blood cells
these tubes of the body, carrying in most cases oxygen-depleted blood toward the heart.
the veins

the lungs
this is a visual representation of your heart beat.
an echocardiogram (EKG)

this is the less technical term for erythrocyte; most abundant formed portion of blood, carry oxygen
the red blood cells
this is the largest blood vessel in your body. all blood leaves the heart through this.
the aorta
This system works together with your heart to make sure your cells have the oxygen they need.
the respiratory system
This is the result of plaque build up and stiffening of the arteries.
