What is the significance of the aorta?

• It is the largest artery in the body, carrying oxygenated blood from the heart to the rest of the body.

• It is responsible for filtering blood before it enters the heart.

• It is the main vein that returns deoxygenated blood to the heart.

• It regulates blood pressure by constricting and dilating.

What does the right side of the heart do?

• Receives blood from the lungs and pumps it to the body.

• Receives blood from the body and pumps it to the lungs.

• Pumps oxygenated blood to the body.

• Filters blood before it enters the lungs.

What is systemic circulation?

• The part of the cardiovascular system that carries oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart.

• The process by which blood is filtered in the kidneys.

• The circulation of blood between the heart and the lungs.

• The movement of blood through the heart only.

What is the Right Ventricle?

• A chamber of the heart that pumps deoxygenated blood to the lungs.

• A chamber of the heart that pumps oxygenated blood to the body.

• A valve that regulates blood flow between the heart and lungs.

• A part of the brain that controls heart rate.

What is the function of capillaries?

• Capillaries are responsible for transporting blood away from the heart.

• Capillaries are tiny blood vessels where the exchange of oxygen, carbon dioxide, nutrients, and waste occurs between blood and tissues.

• Capillaries are large vessels that store blood for later use.

• Capillaries are involved in the production of red blood cells.

What is the role of veins in the cardiovascular system?

• Veins are blood vessels that carry blood back to the heart.

• Veins are responsible for pumping blood away from the heart.

• Veins are the main site for gas exchange in the body.

• Veins are involved in the production of red blood cells.

What is the role of the left side of the heart?

• It receives deoxygenated blood from the body and pumps it to the lungs.

• It receives oxygenated blood from the lungs and pumps it around the body.

• It regulates blood pressure throughout the circulatory system.

• It stores blood before it is pumped to the heart.

What is the pulmonary circulation?

• The part of the cardiovascular system that carries deoxygenated blood from the heart to the lungs and returns oxygenated blood back to the heart.

• The process of oxygenating blood in the heart before it is pumped to the body.

• The circulation of blood that only occurs in the left side of the heart.

• The movement of blood through the digestive system to supply nutrients.

What organ is responsible for pumping blood throughout the body?

• The heart

• The lungs

• The liver

• The kidneys

How does blood flow in the cardiovascular system?

• Blood flows from areas of low pressure to areas of high pressure.

• Blood flows in a circular motion regardless of pressure.

• Blood flows from areas of high pressure to areas of low pressure.

• Blood flows only when the heart is contracting.
