Respiratory and Circulatory Systems

Name one organ of the respiratory systems

• spleen

• liver

• stomach

• trachea

What is the main function of the circulatory system?

• Regulating body temperature

• Producing red blood cells

• Storing excess nutrients

• Transporting oxygen, and nutrients around the body.

Explain the process of gas exchange in the lungs.

• Gas exchange in the lungs occurs through the process of active transport, where oxygen is pumped into the blood and carbon dioxide is pumped out of the blood.

• Gas exchange in the lungs occurs through the process of filtration, where oxygen and carbon dioxide are separated based on their molecular size.

• Gas exchange in the lungs occurs through the process of osmosis, where oxygen and carbon dioxide move across a semi-permeable membrane.

• Gas exchange in the lungs occurs through the process of diffusion, where oxygen from the air in the alveoli diffuses into the blood in the capillaries, and carbon dioxide from the blood diffuses into the alveoli to be exhaled.

How does blood circulate in the body?

• Blood circulates through the lymphatic system

• The heart pumps blood through a network of blood vessels, including arteries, veins, and capillaries.

• Blood is circulated by the nervous system

• Blood circulates through the digestive system

Describe the respiration process.

• Respiration is the process of taking in oxygen and releasing carbon dioxide. It involves breathing, where oxygen is taken in through the nose or mouth and travels to the lungs. In the lungs, oxygen is transferred to the blood and carried to the cells in the body. At the cellular level, oxygen is used to produce energy, and carbon dioxide is produced as a waste product. The carbon dioxide is then carried back to the lungs and exhaled from the body.

• Respiration is the process of taking in water and releasing nitrogen.

• Respiration involves taking in carbon monoxide and releasing nitrogen.

• Respiration is the process of taking in carbon dioxide and releasing oxygen.

Name three parts of the circulatory system.

• brain, spinal cord, nerves

• kidneys, bladder, intestines

• heart, blood vessels, blood

• lungs, liver, stomach

Explain the connection between the circulatory and respiratory systems.

• The circulatory system and respiratory system work together to deliver oxygen to the body's cells and remove carbon dioxide.

• The respiratory system only removes carbon dioxide from the body

• The circulatory system only delivers nutrients to the body

• The circulatory system and respiratory system have no connection

What are the functions of the lungs in the respiratory system?

• To regulate blood sugar levels

• To produce red blood cells

• The functions of the lungs in the respiratory system are to facilitate gas exchange, remove waste gases, and regulate pH levels.

• To store excess water

What is the role of the heart in the circulatory system?

• The role of the heart in the circulatory system is to produce hormones

• The role of the heart in the circulatory system is to regulate body temperature

• The role of the heart in the circulatory system is to pump blood and circulate it throughout the body.

• The role of the heart in the circulatory system is to digest food

How does oxygen get into the bloodstream during gas exchange?

• Oxygen enters the bloodstream through the process of diffusion in the lungs.

• Oxygen is carried into the bloodstream by white blood cells

• Oxygen is absorbed through the skin into the bloodstream

• Oxygen is pumped directly into the bloodstream from the stomach
