Circulatory System Quick Quiz

For blood to pass through the heart from the left

atrium to the left ventricle, it must first pass through

• an artery

• a valve

• a vein

• a capillary

Which statement most accurately describes the

human heart?

• It has two atria and one ventricle, and it pumps

  blood directly into veins.

• It has one atrium and one ventricle, and it is

  composed of cardiac muscle.

• It has one atrium and two ventricles, and it is

  composed of visceral muscle.

• It has two atria and two ventricles, and it

  pumps blood directly into arteries.

The human heart is separated into left and right

sides. This type of structure provides for the

• separation of oxygenated blood from

  deoxygenated blood

• prevention of blood clots in the ventricles

• pumping of blood directly into the atria from

  the ventricles

• circulation of blood in an open circulatory

  system

Which organ system in humans is most directly

involved in the transport of oxygen?

• digestive

• nervous

• excretory

• circulatory

Veins are blood vessels that

• deliver blood to the cells of the body

• contain striated muscle

• carry blood towards the heart

• readily exchange materials between the blood and body cell

Which transport vessel is correctly paired with its

usual function?

• lymph vessels – add blood toward the heart

• capillary – provides a site for the exchange of

  materials between the blood and body tissues

• artery – filters bacteria and dead cells from the

  lymph and the blood

• vein – produces white blood cells

Which function of human blood includes the other

three?

• transporting nutrients

• transporting oxygen

• maintaining homeostasis

• collecting wastes

Which part of the blood is correctly paired with its

function?

• red blood cells – fight infection

• plasma – transports wastes and hormones

• platelets – produce antibodies

• white blood cells – carry oxygen

What is a major difference between red blood cells

and white blood cells?

• Red blood cells contain hemoglobin, but white

  blood cells do not.

• Red blood cells can move, but white blood

  cells cannot.

• Red blood cells contain nuclei, but white blood

  cells do not.

• Red blood cells engulf foreign bacteria, but

  white blood cells do not.

The diagram below represents a microscopic view

of blood. Cell A protects the body by producing specific

chemicals in response to pathogens. Cell A is

• a red blood cell

• a bacteria cell

• an insulin-producing cell

• a white blood cell
