Circulatory System
Major Functions
- Transporting oxygen and removing carbon dioxide.
- Transporting nutrients and removing waste.
- Fighting disease.
- Regulating body temperature.
- Transporting hormones.

Heart- Pumps blood throughout the body.
Arteries- Vessels that transport blood from the heart.
Veins- Vessels that carry blood toward the heart.
Capillaries- A small blood vessel that connects an arteriole and a venule.

Components of Blood
Red Blood Cells- Circulate in blood and carry oxygen.
White Blood Cells- Fight infection.
Platelets-Cytoplasm fragment formed in the bone.
Plasma-Fluid portion of circulating blood.

The Path Blood Goes Through
-Enters the right side of the heart through vena cava.
-Goes through tricuspid valve.
-Enters the right ventricle.
-Pumped into the pulmonary vein.
-Gets oxygenated in the lungs.
-Enters the left side from the lungs.
-Goes through the bicuspid valve.
-Pumped out left ventricle into aorta.
-Branches off through all the arteries in the body.

How it works with other body systems
- Works with the Nervous System because Endothelial cells maintain the blood brain barrier.
- Works with the Skeletal System because the bones produce blood cells.
- Works with the Endocrine System because it secretes hormones into the circulatory system.
