differents betwwen pulmonary system and systemic system
The pulmonary system and systemic system are two separate but interconnected systems within the human body that work together to facilitate gas exchange and deliver oxygen to all cells in the body. However, there are some key differences between the two systems:
1. Pulmonary System:
- The pulmonary system is responsible for transporting oxygen from the air to the bloodstream and removing carbon dioxide from the bloodstream to be exhaled.
- It includes the lungs, bronchi, bronchioles, and alveoli.
- The primary function of the pulmonary system is ventilation (breathing) and gas exchange.
- It helps maintain the acid-base balance in the body by regulating the levels of carbon dioxide and oxygen in the blood.
- Blood is pumped from the heart to the lungs via the pulmonary arteries, where it becomes oxygenated, and then returns to the heart via the pulmonary veins.
2. Systemic System:
- The systemic system is responsible for delivering oxygenated blood to all cells in the body and removing waste products from these cells.
- It includes the heart, arteries, veins, and capillaries.
- The primary function of the systemic system is to deliver oxygen and nutrients to cells and remove carbon dioxide and waste products.
- It helps maintain blood pressure and circulation throughout the body.
- Blood is pumped from the heart to the rest of the body via the systemic arteries and returns to the heart via the systemic veins.
Overall, the pulmonary system is responsible for gas exchange and maintaining the body's oxygen and carbon dioxide levels, while the systemic system is responsible for delivering oxygenated blood to all cells in the body and removing waste products. Both systems work together to ensure the body's cells receive the necessary nutrients and oxygen for optimal functioning.
