Which of the following best describes the relationship between the circulatory and respiratory systems?
Which of the following best describes the relationship between the circulatory and respiratory systems?
- Both systems independently regulate blood pressure and heart rate.
- The circulatory system removes carbon dioxide from the air, and the respiratory system transports it to the cells.
- The respiratory system delivers oxygen to the blood, which the circulatory system then transports to the body's cells. (correct)
- The circulatory system provides the structure for gas exchange, while the respiratory system transports gases.
During internal respiration, what process occurs?
During internal respiration, what process occurs?
- The exchange of gases between the air and the blood in the lungs.
- The oxygenation of blood within the heart chambers.
- The movement of air in and out of the lungs.
- The exchange of gases between the blood and the body's cells. (correct)
Arteriosclerosis reduces blood flow because:
Arteriosclerosis reduces blood flow because:
- it increases the number of red blood cells, which clog the arteries.
- it causes the blood to become too thick to flow easily.
- it hardens the arteries, narrowing the space for blood to flow. (correct)
- it weakens the heart muscle, reducing its ability to pump blood.

Study Notes
Circulatory System
- A group of organs and tissues that transports essential supplies to body cells while removing waste products.
- Also referred to as the cardiovascular system.
Respiratory System
- Moves oxygen and carbon dioxide between the air and the body.
Cell Respiration
- The process where the body's cells are nourished and energized.
- Formula: Oxygen + Food → Carbon dioxide + energy + water
Circulatory System Diseases
- Stroke: A blood clot blocking vessels in the brain.
- Heart Attack: Blockage of blood flow to the heart.
- Arteriosclerosis: Hardening of arteries, reducing blood flow.
- Leukemia: Cancer causing excessive abnormal white blood cells.
Respiration Types
- Internal Respiration: Gas exchange between blood and body cells.
- External Respiration: Oxygen and carbon dioxide exchange between blood and air in the lungs.
Respiratory System Diseases
- Asthma: A common chronic condition causing narrowing or blockage of respiratory system air passages.
- Bronchitis: Infected and swollen bronchi caused by a virus.
- Pneumonia: Lung infection that inflames alveoli, filling them with fluid.
Types of Blood Vessels
- Arteries: Carry oxygenated blood and nutrients from the heart to the body.
- Veins: Carry deoxygenated blood back to the heart.
- Capillaries: Deliver oxygen and nutrients to cells and remove carbon dioxide.
Components of Blood and Their Functions
- Red Blood Cells: Transport oxygen from the lungs to the rest of the body.
- White Blood Cells: Combat bacteria and viruses.
- Plasma: Creates substances to eliminate bacteria/viruses and prevent infections.
- Platelets: Facilitate blood clotting to stop bleeding.
Pathway of Air
- Air enters through the nose/mouth, proceeds to the pharynx, then the larynx, to the trachea, to the bronchial tubes, and finally to the alveoli.
Parts of the Respiratory System and Their Functions
- Larynx: Contains vocal cords.
- Trachea: The windpipe which directs air to the lungs.
- Lungs: Facilitate oxygen transfer to the blood and carbon dioxide removal.
- Bronchi: Main passageways for air entering the lungs.
- Alveoli: Tiny air sacs in the lungs where carbon dioxide is exchanged with oxygen.
- Diaphragm: A dome-shaped muscle separating the chest from the abdomen.
Ways to Care for the Circulatory System
- Decrease stress
- Eat healthily
- Exercise
- Avoid tobacco
Ways to Care for the Respiratory System
- Avoid polluted air
- Don’t use tobacco
- Wash hands and avoid touching nose/mouth
- Engage in physical activity
Impact of Exercise on Circulatory and Respiratory Systems
- Circulatory System: Heartbeat increases, and blood pumps more vigorously.
- Respiratory System: Breathing becomes harder, increasing the workload for the lungs.
