Identify the functions of the CV system

• Platelets

  Plasma

  Red blood cells

  White blood cells

• Arteries

  Veins

  Capillaries

• Transport of blood

  Blood clotting

  Red blood cells

• Temperature regulation

  Transport of O2, glucose and CO2

  Blood clotting

Which blood vessel is responsible for gaseous exchange?

• Arteries

• Capillaries

• Veins

Which blood vessel has pocket valves to prevent back flow of blood

• Arteries

• Veins

• Capillaries

Describe the structure of the alveoli

• The membrane is one cell thick to allow for gaseous exchange

• The membrane is thick to prevent back flow of gasses during gaseous exchange

• The alveoli has a surface area and thick membrane

• Wide surface area and a one cell thick membrane to allow for gaseous exchange

The three blood vessels are:

• Blood transport

What is the name of the blood vessel that transports de-oxygenated blood from the heart to the lungs?

When a person inhales more frequently during exercise, is there a high or low concentration of oxygen in the alveoli?

• High

• Low

During exercise, where does vasoconstriction occur?

• Arteries leading to the working muscles

• Arteries leading to the vital organs, such as the brain

• Arteries leading to non-vital organs, such as the digestive system

What causes the lungs to inflate during inhalation?

• Intercostal muscles

• Diaphragm

• Ribs

• The mouth
