Heart
Blood vessels
Blood vessels
Arteries
Direction of blood flow: blood away from the heart
Thickness: Very Thick
Blood type: Oxygenated Blood except Pulmonary Arteries
Structure (In to Out): Endothelium , Smooth muscle( Thick) and connective tissue
Veins
Thickness: Not as thick as the arteries, thicker than the capillaries
Blood type: Oxygen poor blood
Structure: Endothelium, smooth muscle,connective tissues, valve
Direction of blood flow: Blood to the heart
Capillaries
Thickness
Narrow
Blood type:
Depends on the type
Direction of blood flow:

Blood
Heart
A hollow muscular organ that pumps blood throughout the body.
Cardiac muscle (involuntary)
Pumps the oxygenated blood to the body and deoxygenated to lungs.
4 chambers separated by the septum, the upper part is called the atria and the lower part is called the ventricle
4 Chambers
Right Ventricle
Send deoxygenated blood to lungs
Left Atrium receives the oxygenated blood from the lungs
