Circulatory System Quiz

What is the main function of the circulatory system?

• Transporting essential substances throughout the body

• Digesting food

• Producing hormones

• Regulating body temperature

Name the four main components of the circulatory system.

• heart, blood vessels, blood, lymphatic system

• stomach

• brain

• lungs

What is the role of red blood cells in the circulatory system?

• Red blood cells produce antibodies in the circulatory system.

• Red blood cells carry oxygen and carbon dioxide in the circulatory system.

• Red blood cells regulate blood pressure in the circulatory system.

• Red blood cells transport nutrients in the circulatory system.

Explain the difference between arteries and veins.

• Arteries have valves, veins do not have valves.

• Arteries carry deoxygenated blood, veins carry oxygenated blood.

• Arteries carry oxygenated blood, veins carry deoxygenated blood.

• Arteries are thin-walled, veins are thick-walled.

What is the purpose of capillaries in the circulatory system?

• To produce hormones that control blood pressure

• To regulate body temperature by releasing heat

• To facilitate the exchange of oxygen, nutrients, and waste products between the blood and tissues.

• To store excess nutrients for future use

How does the heart pump blood throughout the body?

• By using telekinesis to move the blood

• Through a series of underground tunnels

• By sending text messages to the blood cells

• Through rhythmic contraction and relaxation of the heart chambers

Describe the pathway of blood flow through the heart.

• Superior and inferior vena cava -> Right atrium -> Tricuspid valve -> Right ventricle -> Pulmonary valve -> Pulmonary artery -> Lungs -> Pulmonary veins -> Left atrium -> Mitral valve -> Left ventricle -> Aortic valve -> Aorta

• Superior and inferior vena cava -> Left atrium -> Mitral valve -> Left ventricle -> Aortic valve -> Aorta -> Pulmonary valve -> Pulmonary artery -> Lungs -> Pulmonary veins -> Right atrium -> Tricuspid valve -> Right ventricle

• Inferior vena cava -> Right atrium -> Mitral valve -> Left ventricle -> Aortic valve -> Aorta -> Pulmonary valve -> Pulmonary artery -> Lungs -> Pulmonary veins -> Left atrium -> Tricuspid valve -> Right ventricle

• Superior vena cava -> Left atrium -> Tricuspid valve -> Right ventricle -> Pulmonary valve -> Pulmonary artery -> Lungs -> Pulmonary veins -> Right atrium -> Mitral valve -> Left ventricle -> Aortic valve -> Aorta

What is the significance of the pulmonary circulation in the circulatory system?

• Pulmonary circulation helps in digesting food.

• Pulmonary circulation is responsible for regulating body temperature.

• Pulmonary circulation is only important for the brain function.

• Pulmonary circulation is essential for oxygenating blood and ensuring proper oxygen supply to the body.

How does the lymphatic system work in conjunction with the circulatory system?

• The lymphatic system only transports red blood cells.

• The lymphatic system transports lymph containing white blood cells and filters it through lymph nodes before returning it to the circulatory system.

• The lymphatic system is not connected to the circulatory system.

• The lymphatic system transports oxygenated blood to the circulatory system.

What are some common disorders or diseases related to the circulatory system?

• asthma

• arthritis

• hypertension, coronary artery disease, heart failure, stroke, peripheral artery disease

• diabetes
