Chapter 3.7 The circulatory system in animals

What is plasma?

• The upper chamber of the heart

• The liquid part of the blood or lymph

• The lower chambers of the heart

• The inside space of a body structure or organ

What is deoxygenated blood?

• The upper chamber of the heart

• The liquid part of the blood or lymph

• Blood that has a high concentration of oxygen and a low concentration of carbon dioxide

• Blood that has low concentration of oxygen and high concentration of carbon dioxide

What is an atrium?

• The upper chamber of the heart

• The lower chambers of the heart

• A small artery which takes blood from arteries to capillaries

• A small vein connecting capillaries to larger veins

What is an arteriole?

• The upper chamber of the heart

• The lower chambers of the heart

• A small artery which takes blood from arteries to capillaries

• A small vein connecting capillaries to larger veins

What is a venule?

• The upper chamber of the heart

• The lower chambers of the heart

• A small artery which takes blood from arteries to capillaries

• A small vein connecting capillaries to larger veins

What is an open circulatory system?

• Movement of fluid is not wholly confined to tubes

• Movement of fluid is completely confined to tubes

• Blood that has a high concentration of oxygen and a low concentration of carbon dioxide

• Blood that has low concentration of oxygen and high concentration of carbon dioxide

What is a closed circulatory system?

• Movement of fluid is not wholly confined to tubes

• Movement of fluid is completely confined to tubes

• Blood that has a high concentration of oxygen and a low concentration of carbon dioxide

• Blood that has low concentration of oxygen and high concentration of carbon dioxide

What is the function of plasma?

• Transport to all cells for metabolic processes e.g. aerobic respiration

• Transport to lungs for excretion from the body

• Transmit chemical messages to the organs to maintain a stable internal environment

• Transport to kidneys for excretion from the body

What is the function of red blood cells?

• Transport of oxygen to all cells for aerobic respiration

• Destroy bacteria and viruses that have invaded the body

• Contribute to the clotting of blood

• Transport to kidneys for excretion from the body

What is the function of white blood cells?

• Transport of oxygen to all cells for aerobic respiration

• Destroy bacteria and viruses that have invaded the body

• Contribute to the clotting of blood

• Transport to kidneys for excretion from the body
