Cardiorespiratory System

Which shows the correct sequence of blood flow in the heart?

• superior & inferior vena cava > right atrium > right ventricle > pulmonary veins > lungs > left atrium > pulmonary artery > left ventricle > aorta > body

• superior & inferior vena cava > right atrium > left ventricle > left atrium > pulmonary artery > lungs > pulmonary veins > right ventricle > aorta > body

• superior & inferior vena cava > right atrium > right ventricle > pulmonary artery > lungs > pulmonary veins > left ventricle > left atrium > aorta > body

• superior & inferior vena cava > left atrium > left ventricle > right atrium > pulmonary artery > lungs > pulmonary veins > right ventricle > aorta > body

The blood vessels that carry oxygen-rich blood from the heart to the body are

• Arteries

• Veins

• Capillaries

• Tubules

Besides delivering oxygen to your muscles, what is another important function of the cardiorespiratory system?

• Eliminating carbon dioxide from cells

• Obtaining nutrients from food

• Absorbing vitamins

• Eliminating carbon monoxide from cells

After picking up oxygen from the lungs and going back to the heart, the correct order of an oxygenated red blood cell traveling to a muscle from the heart is

• Vein, capillary, muscle

• Vein, artery, muscle

• Artery, capillary, muscle

• Artery, vein, muscle

Gas exchange between the blood and the outside occurs in which system?

• Respiratory

• Circulatory

• Lymphatic

• Integumentary

The respiratory system is responsible for

• Obtaining food and excreting waste

• Obtaining carbon dioxide and eliminating oxygen

• Obtaining white blood cells and removing red blood cells

• Obtaining oxygen and eliminating carbon dioxide

What body system consists of the lungs

• Respiratory

• Circulatory

• Muscular

• Skeletal

What is the main function of the respiratory system?

• to provide oxygen and remove carbon dioxide from the body

• to bring oxygen to the body

• to break down food and absorb nutrients

• to remove oxygen from the body and deliver carbon dioxide

Gathers oxygen from the environment and gets rid of carbon dioxide from the body.

• cardiovascular system

• respiratory system

• endocrine system

• lymphatic system

Which of the following describes how the cardiovascular system works with the respiratory system to provide oxygen to muscles?

• Respiratory system: inhalation of oxygen and exhalation of carbon dioxide. Alveoli/capillaries: site of gas exchange. Cardiovascular system: pumps blood and delivers oxygen to muscle cells.

• Cardiovascular system: inhalation of oxygen and exhalation of carbon dioxide. Alveoli/capillaries: site of gas exchange. Respiratory system: pumps blood and delivers oxygen to muscle cells.

• Respiratory system: inhalation of oxygen and exhalation of carbon dioxide. Trachea/capillaries: site of gas exchange. Cardiovascular system: pumps blood and delivers oxygen to muscle cells.

• Respiratory system: inhalation of oxygen and exhalation of carbon monoxide. Arteries/capillaries: site of gas exchange. Cardiovascular system: pumps blood and delivers oxygen to muscle cells.
