Cardiovascular System

What is the circulatory System?

• The body's energy producing system

• The body's system of nerves

• The body's support and movement system

• The body's transporting system

All is true for double circulations, but that it

• occur in all vertebrates

• occur only in mammals

• is composed of pulmonary circulation

• is composed of systematic circulation

Oxygenated blood

• leaves from left side of the heart

• leaves from right side of the heart

• does not leave the lungs

• enters the lungs from the heart

Pulmonary circulation links

• blood from pulmonary arteries to pulmonary veins

• blood from pulmonary veins to pulmonary arteries

• blood from lungs to heart

• blood in closed circulation system

Systematic circulation

• carry blood to the left side of the heart

• carry blood to the right side of the heart

• carry oxygenated blood from lungs to heart

• carry red oxygenated blood

All veins carry deoxygenated blood except

• pulmonary vein

• hepatic vein

• hepatic portal vein

• renal vein

In open circulatory system, blood is pumped through

• sinuses to large vessels

• large vessels to sinuses

• cavities to organs

• spaces to large vessels

The passage of blood from left atrium to body is

• left atrium-left ventricle-aorta-body

• left atrium-right ventricle-aorta-body

• left atrium-left ventricle-pulmonary artery-body

• left atrium-left ventricle-pulmonary vein-body

The pathway of single circulation is

• heart- body- gills- heart

• heart- gills -body -heart

• heart- body- gills -body- heart

• body -heart -gills -heart

In single circulation, the heart pumps

• Oxygenated blood

• Deoxygenated blood

• mixed blood

• blood-nutrients
