Circulatory Systems Quiz

What is a characteristic of open circulatory systems?

• High pressure

• Hemolymph as circulatory fluid

• Effective delivery of O2

• Blood vessels

Which component is NOT part of the basic components of a circulatory system?

• A muscular pump

• A circulatory fluid

• A nervous system

• A set of tubes

In closed circulatory systems, what is the primary circulatory fluid?

• Hemolymph

• Blood

• Lymph

• Interstitial fluid

Which type of blood vessel carries blood away from the heart?

• Arteries

• Capillaries

• Venules

• Veins

What is the function of the heart in the circulatory system?

• To filter blood

• To store blood

• To pump blood

• To oxygenate blood

What is correct in a single circulation?

• bony fishes, rays, sharks, and birds

• gill circulation, systemic circulation.

• It has a ventricle that goes to the gills, a vein that travels back to the heart from systemic circulation

• Pulmocutaneous
  circuit, systemic circulation

What is the difference between: Amphibians, Reptiles, and Birds/Mammals double circulation?

• Amphibians: lung and skin capillaries
  Reptiles: Lung capillaries

  Birds/Mammal: lung capillaries

• Amphibians: lung and skin capillaries
  Reptiles: skin capillaries

  Birds/Mammal: lung capillaries

• Amphibians: lung and skin capillaries
  Reptiles: Lung capillaries + right systemic aorta

  Birds/Mammal: lung capillaries

• Amphibians: lung and skin capillaries
  Reptiles: Lung capillaries + left systemic vein

  Birds/Mammal: lung capillaries

1. Contraction of the
_____ ____________
blood to the lungs.

Answer explanation

The correct answer is 'right ventricle' because it is the chamber of the heart responsible for contracting and pumping deoxygenated blood to the lungs for oxygenation.

2. In the lungs, the
blood loads O2 and
unloads CO2.

3. 3. O2-rich blood
   returns from lungs
   via ________
   to left atrium
   

Answer explanation

O2-rich blood returns from the lungs to the left atrium via the pulmonary veins. This is the correct pathway for oxygenated blood after gas exchange in the lungs.

4. O2-rich blood
flows into left
ventricle.
5. The ____ _______
pumps O2-rich blood out
through the _____ to the
heart muscle itself and
body tissues.

Answer explanation

The left ventricle pumps O2-rich blood out through the aorta, supplying oxygen to the heart muscle and body tissues. This is a key function of the heart's left ventricle.
