Alt Assignment- Circ and Resp

What is the primary function of the respiratory system?

• To circulate blood throughout the body

• To exchange gases between the body and the environment

• To digest food

• To produce hormones

Which part of the circulatory system is responsible for carrying oxygenated blood from the lungs to the heart?

• Arteries

• Veins

• Capillaries

• Pulmonary veins

Explain how the diaphragm contributes to the process of inhalation.

• It contracts and moves upward, increasing the pressure in the chest cavity.

• It relaxes and moves downward, decreasing the pressure in the chest cavity.

• It contracts and moves downward, decreasing the pressure in the chest cavity.

• It relaxes and moves upward, increasing the pressure in the chest cavity.

How do the respiratory and circulatory systems work together to maintain homeostasis in the body?

• By exchanging nutrients and waste products

• By regulating body temperature

• By delivering oxygen to cells and removing carbon dioxide

• By producing red blood cells

Which of the following best describes the role of hemoglobin in the circulatory system?

• It transports nutrients to cells.

• It carries oxygen from the lungs to the rest of the body.

• It helps in the digestion of food.

• It regulates blood pressure.

Describe the process of gas exchange in the alveoli.

• Oxygen diffuses from the alveoli into the blood, and carbon dioxide diffuses from the blood into the alveoli.

• Carbon dioxide diffuses from the alveoli into the blood, and oxygen diffuses from the blood into the alveoli.

• Oxygen and carbon dioxide are actively transported across the alveolar membrane.

• Oxygen is absorbed by the alveoli, and carbon dioxide is released into the blood.

Analyze how a blockage in the coronary arteries can affect the interaction between the respiratory and circulatory systems.

• It can lead to increased oxygen supply to the heart, improving overall function.

• It can cause a decrease in oxygen supply to the heart, leading to potential heart damage.

• It can enhance the efficiency of gas exchange in the lungs.

• It can increase the rate of blood flow to the lungs.

Evaluate the impact of high altitude on the interaction between the respiratory and circulatory systems.

• High altitude increases oxygen availability, reducing the need for increased breathing rate.

• High altitude decreases oxygen availability, requiring the body to increase breathing rate and red blood cell production.

• High altitude has no effect on the respiratory and circulatory systems.

• High altitude decreases carbon dioxide levels, leading to decreased breathing rate.
