Circulatory System Overview

Arteries carry blood from your heart to your lungs.

What carries blood from the upper part of the body to the heart?

What carries blood from the lower part of the body to the heart?

What is the straw-colored liquid in blood where other components float?

What is a special fluid primarily contained within the blood vessels?

What is the thin sac that surrounds your heart?

Which organ is often referred to as the 'most hardworking' organ?

What aids in the production of serous fluid secreted into the pericardial sac?

What determines blood type?

What is the largest blood vessel that delivers nutrients and hormones?

What collects oxygen-rich blood from the lungs and carries it to the heart?

What in the blood fights diseases and protects the body from infection?

What gathers at the site of injury to help the clotting process?

What directly covers your heart and roots of your great vessels?

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.
