Study Notes
External Respiration
- The process of gas exchange between the lungs and the blood.
Pulmonary Circulation
- The circulatory system that carries deoxygenated blood from the heart to the lungs and returns oxygenated blood back to the heart.
Intercostal Muscles
- Located between the ribs and are responsible for expanding and contracting the chest cavity, which is essential for breathing.
Gas Exchange
- Occurs in the alveoli, tiny air sacs in the lungs.
Respiratory System
- Primarily responsible for taking in oxygen and expelling carbon dioxide, which is essential for cellular respiration and life.
