Human Circulatory System

What are the three types of blood vessels in the human body?

• arteries, veins and capillaries

• pulmonary, coronary, splenic

• veins, arterioles, lymphatics

• aorta, venules, sinusoids

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

• The main function of the heart in the circulatory system is to pump blood throughout the body.

• The heart has no function in the circulatory system

• The heart only regulates body temperature

• The main function of the heart is to produce red blood cells

How many chambers does the human heart have and what are their names?

• The human heart has 4 chambers: two atria (or atriums) and two ventricles.

• The human heart has 3 chambers: one atrium and two ventricles.

• The human heart has 5 chambers: three atria and two ventricles.

• The human heart has 6 chambers: four atria and two ventricles.

Describe the path that blood follows through the circulatory system, starting with the superior vena cava.

• vena cava superior - left atrium - right ventricle - aorta - pulmonary veins

• vena cava superior - right atrium - left ventricle - pulmonary artery - pulmonary veins

• vena cava superior - aorta - left atrium - right ventricle - pulmonary veins

• The blood follows the route vena cava superior - right atrium - right ventricle - pulmonary artery - pulmonary veins - left atrium - left ventricle - aorta.

What is the main function of the arteries in the circulatory system?

• Transport oxygenated blood from the rest of the body to the heart.

• Transport oxygenated blood from the heart to the rest of the body.

• Transport nutrients from the heart to the rest of the body.

• Transport deoxygenated blood from the body to the heart.

What type of blood does the pulmonary vein carry?

• Oxygenated blood

• Deoxygenated blood

• Blood type B

• Blood type AB

What is the function of the valves in the heart?

• The valves in the heart are responsible for the production of red blood cells

• The function of the valves in the heart is to control the blood flow and ensure that the blood flows in one direction through the chambers of the heart.

• The valves in the heart only serve to regulate the body's temperature

• The valves in the heart have no specific function

What is the name of the main artery that carries blood from the heart to the rest of the body?

• Vena cava

• Carotid artery

• Aorta

• Pulmonary artery

What happens in the blood capillaries?

• Capillary blood vessels have no function in the body

• Capillary blood vessels transport blood to the heart

• Exchange of nutrients, oxygen, and waste occurs between the blood and the body's tissues.

• Capillary blood vessels are responsible for the production of red blood cells

What is the function of red blood cells in the blood?

• Transport oxygen from the lungs to all cells of the body and carry carbon dioxide back to the lungs to be exhaled.

• Produce insulin to regulate the level of sugar in the blood

• Regulate blood pressure in the body

• Fight infections and diseases
