• Blood flow
• Oxygen-poor
• Water Flow

Which is the correct definition of the Circulatory system?

• The system fights disease so the body stays healthy.
• The system that circulates blood and oxygen through the body, consisting of the heart,blood vessels,and blood.
• Breaks down food into smaller pieces and absorbs those nutrients into the body.
• Provides shape and structure for the body.

What do Red-Blood cells do?

• Carry oxygen from the lungs to the body cells and  transport carbon dioxide from the cells back to the lungs
• keeps blood flowing in one direction to the heart and prevent blood from flowing backwards
• Collects  blood from the capillaries and drain it into the veins
• Bring nutriients to the cells and carries away waste materials.

The circulatory system works with the ___________ system to provide our body with oxygen.

• respiratory
• digestive
• muscular
• skeletal

What is pulmonary circulation?

• Blood travelling to and from the lungs
• Blood travelling to and from the body
• A blood clot in the lungs
• The vessel that brings blood to the lungs

Coronary arteries...

• supply the heart muscle cells with a supply of blood.

• supply the brain cells with a supply of blood.

• contain deoxygenated blood.

• when clogged, cause a stroke.

Which of the following does NOT assist in the return of venous blood to the heart?

• veins have one-way valves

• the contraction of skeletal muscles squeeze the vein

• veins have a larger diameter therefore can hold more blood

• the contraction of muscle layers in the veins keeps the blood flowing in the right direction

Which statement best describes how the circulatory system responds when the external environment is cold and body heat needs to be conserved?

• Vasoconstriction of the blood vessels near the surface of the skin reduces the amount of heat that is dissipated from the skin.

• Vasoconstriction of the blood vessels near the surface of the skin increases the amount of heat that is dissipated from the skin.

• Vasodilation of blood vessels near the surface of the skin reduces the amount of heat that is dissipated from the skin.

• Vasodilation of blood vessels near the surface of the skin increases the amount of heat dissipated from the skin.
