System where blood is not always contained within vessels; blood can be emptied into the body cavity for pickup

System where blood is always contained within vessels

Rapid gas exchange is possible because:

Which system type (closed or open) has a higher pressure

Absorbs O2 and releases CO2 at the lungs, then returns oxygenated blood to the heart

Circulates blood throughout the body to drop off fresh O2 and pick up used CO2, then returns to the heart

What is the function of platelets?

Makes up the majority of blood:

Responsible for fighting infection:

Blood cell type responsible for transporting O2 and CO2:

The cells that are the precursor to all other blood cells

Where do blood cells originate in the body?

The red, iron rich protein that makes O2 movement possible

Protein found on the cell membrane that recognizes friendly and foreign cells

Protein that free-floats in the plasma and destroys forgein antigens

The blood type that lacks both antigens; the universal donor

The blood type that lacks both antibodies; the universal recipient

A type of antigen that determines + or - blood type:

If the Rh antigen is present, the blood type has this sign:

Exposure of an Rh + blood type to Rh - blood types causes what to be made to attack the Rh - blood?

Cells within the heart that rhythmically generate contractions:

Term that describes the heart's ability to contract without input from the nervous system:

These blood cells have a nucleus:

Red blood cells have no nucleus, and therefore cannot undergo apoptosis. They are destroyed in the _______ by _______.

Old platelets are removed in these 2 organs:

In humans, hemoglobin bonds with O2 to move it through the system. Other animals use different _______ to move O2, causing variations in blood color.
