Explore the Circulatory System

What are the three main types of blood vessels?

• arteries, capillaries, blood cells

• veins, capillaries, plasma

• arteries, veins, lymphatics

• arteries, veins, capillaries

What is the function of arteries in the circulatory system?

• The function of arteries is to transport oxygenated blood from the heart to the rest of the body.

• To transport deoxygenated blood from the body to the heart.

• To filter blood and remove waste products.

• To regulate body temperature through blood flow.

How do veins differ from arteries?

• Veins have thicker walls than arteries.

• Veins carry oxygenated blood away from the heart.

• Veins differ from arteries in that they carry deoxygenated blood to the heart and have thinner walls with valves, while arteries carry oxygenated blood away from the heart and have thicker walls.

• Arteries have valves and carry deoxygenated blood to the heart.

What role do capillaries play in blood circulation?

• Capillaries are responsible for pumping blood throughout the body.

• Capillaries enable the exchange of substances between blood and tissues.

• Capillaries transport oxygen from the lungs to the heart.

• Capillaries store excess blood for emergencies.

Describe the process of blood circulation in the body.

• Oxygen is absorbed through the skin during circulation.

• Blood circulation is the process of blood being pumped from the heart to the body and back, involving oxygenation in the lungs.

• Blood circulation only occurs in the heart.

• Blood is filtered in the kidneys before circulation.

What is the path of blood flow starting from the heart?

• Heart → Aorta → Veins → Capillaries → Arteries → Right Atrium

• Heart → Aorta → Arteries → Arterioles → Capillaries → Venules → Veins → Superior/Inferior Vena Cavae → Right Atrium

• Heart → Arterioles → Veins → Superior Vena Cavae → Right Atrium

• Heart → Pulmonary Arteries → Lungs → Aorta → Capillaries

What are the main components of blood?

• Plasma, hormones, and enzymes.

• Muscle cells, nerve cells, and connective tissue.

• Red blood cells, white blood cells, platelets, and plasma.

• Red blood cells, white blood cells, and lymph nodes.

What is the function of red blood cells?

• To store nutrients and vitamins.

• To fight infections and diseases.

• To produce insulin for the body.

• To transport oxygen and carbon dioxide in the body.

What do white blood cells do in the body?

• White blood cells help defend the body against infections and foreign invaders.

• White blood cells are responsible for oxygen transport.

• White blood cells primarily aid in digestion.

• White blood cells produce hormones for growth.

What is plasma and what does it contain?

• Plasma is an ionized gas containing ions, electrons, and neutral particles.

• Plasma is a liquid that consists of water and minerals.

• Plasma is a solid containing only protons and neutrons.

• Plasma is a type of gas that contains only molecules and no charged particles.
