B7 Quiz - Circulation

Question 1 of 12

1

Humans - and all other mammals - have a double circulatory system which comprises two separate circuits.
What does it mean to say the human heart is a 'double pump?

Select one of the following:

  • Blood pumps through the heart twice during a complete journey around the body.

  • Blood moves around the body at two different speeds.

  • Blood is pumped twice before leaving the heart.

Explanation

Question 2 of 12

1

The blood in each 'circuit' is interchanged.

Select one of the following:

  • True
  • False

Explanation

Question 3 of 12

1

Choose the statements which are correct descriptions of arteries.

Select one or more of the following:

  • They carry blood towards the heart.

  • They have very thin walls (only one cell thick) to allow for maximum exchange of substances.

  • They have thick, muscular walls to withstand the high pressure of blood

  • They carry blood away from the heart.

  • They contain valves to prevent blood flowing backwards and 'pooling'.

Explanation

Question 4 of 12

1

Choose the correct order:

1. It is pumped to the lungs, via the pulmonary artery where it is oxygenated.
2. The left side of the heart pumps oxygenated blood from the lungs, through the aorta to the body tissues (excluding the lungs).
3. Blood returns to the left side of the heart, via the pulmonary vein and is pumped to the body tissues again.
4. Deoxygenated blood returns from the body tissues to the right side of the heart, via the vena cava.

Select one of the following:

  • 2, 4, 1, 3

  • 3, 2, 4, 1

  • 1, 2, 3, 4

  • 2, 1, 4, 3

Explanation

Question 5 of 12

1

The heart is mainly made from . The left ventricle of the heart has a muscle wall because it needs to pump blood further, and at a higher , around the body. The right ventricle is under pressure as it only needs to pump blood to the .

The heart needs a supply of oxygen and glucose for . The artery is a branch of the aorta which transports to the heart muscle itself.

A in one of the branches of the coronary artery can severely interrupt blood flow and is called a .

Question 6 of 12

1

Which of the four components of blood is being described?
The liquid part of blood. It transports nutrients (eg glucose), amino acids, antibodies and hormones to tissues that need them. It also transports waste substances: carbon dioxide and water to the lungs, and water and urea to the kidneys.

Select one of the following:

  • plasma

  • red blood cells

  • white blood cells

  • platelets

Explanation

Question 7 of 12

1

Which of the four components of blood is being described?
They transport oxygen, which is bound to haemoglobin.

Select one of the following:

  • red blood cells

  • white blood cells

  • platelets

  • plasma

Explanation

Question 8 of 12

1

Which of the four components of blood is being described?
They are part of the body’s immune system and fight infection.

Select one of the following:

  • red blood cells

  • white blood cells

  • platlets

  • plasma

Explanation

Question 9 of 12

1

Which of the four components of blood is being described?
They stick together when a blood vessel is damaged in order to help form a clot.

Select one of the following:

  • red blood cells

  • white blood cells

  • plasma

  • platelets

Explanation

Question 10 of 12

1

Red blood cells' lack of a nucleus is so they are smaller.

Select one of the following:

  • True
  • False

Explanation

Question 11 of 12

1

Red blood cells are a biconcave shape. This kind of shape (which is disc like) gives them an increased surface area for oxygen exchange.

Select one of the following:

  • True
  • False

Explanation

Question 12 of 12

1

By the time blood reaches the capillary beds from an , it is at high pressure and this forces blood out. The plasma leaves the capillary and becomes fluid. As the blood plasma moves through the capillary bed towards the vein, drops and stops plasma being squeezed out.

Tissue fluid acts as a bridge in the of chemicals between the capillaries and the cells of the tissue. Oxygen and diffuse from the blood into the tissue fluid and then into the cells. Carbon dioxide and diffuse from the cells into the tissue fluid, which back into the blood due to the pressure.
