Study Notes
Open Circulatory System
- Organisms with open circulatory systems lack a true heart and capillaries.
- Blood remains within blood vessels, separate from body tissues.
- A heart pumps blood through a continuous circulation pattern.
Closed Circulatory System
- Blood stays within blood vessels.
- Blood is kept separate from body tissues.
- This system has a heart that pumps blood through a continuous circulation pattern.
Blood Vessels
- Tubes or channels that carry blood throughout our body.
Sickle Cell Disease
- Inherited blood disorder.
- Red blood cells become hard and sticky, forming a C-shaped cell instead of the healthy disc-shaped cell.
Arteries
- Carry blood from your heart to your lungs.
Superior Vena Cava
- Carries blood from the upper part of the body to the heart.
Inferior Vena Cava
- Carries blood from the lower part of the body to the heart.
Plasma
- Straw-colored liquid where other blood components float.
- Mostly water.
Blood
- Special fluid primarily contained within blood vessels.
Pericardium
- Thin sac that surrounds your heart.
- Protects and lubricates the heart and keeps it in place within the chest.
Heart
- The "most hardworking" organ.
- Aids in the production of serous fluid secreted into the pericardial sac.
Blood Type
- Determined by the presence or absence of certain antigens - substances that can trigger an immune response if foreign to the body.
Aorta
- Largest blood vessel.
- Delivers nutrients and hormones throughout the body.
Pulmonary Veins
- Collect oxygen-rich blood from your lungs and carry it to your heart.
White Blood Cells
- Fight diseases and protect the body from infection.
Platelets
- Gather at the site of injury and help the clotting process.
Epicardium
- Directly covers your heart and the roots of your great vessels.
- Also known as the epicardium.
