Pathological Conditions of the Pulmonary Blood Vessels
The respiratory system’s key component is the lungs, which serve as the primary site for gas exchange. During respiration, the lungs continuously take in oxygen while removing carbon dioxide from the body. Proper blood supply is essential for optimal lung function, as it not only facilitates gas exchange but is also responsible for nourishing lung tissue. The close relationship between the lung vessels and the heart is crucial for the effective functioning of both the respiratory and circulatory systems. Understanding the blood supply to the lungs is vital for recognizing the importance of maintaining respiratory health. Diseases of the lung vessels can cause serious health issues that affect both breathing…

What are cerebral circulation disorders?
The proper blood supply to the brain is essential for human life. The brain’s circulation requires approximately 750-800 milliliters of blood per minute, which represents 15-20% of the total circulating blood. The brain is extremely sensitive to interruptions in blood supply; if this supply completely stops, severe disturbances in brain function can occur within five seconds. If the blood supply is interrupted for more than three minutes, it generally leads to permanent damage, while interruptions lasting longer than six minutes can result in irreversible brain damage, also known as brain death. Blood Supply to the Brain The brain’s blood supply is realized through bilateral carotid arteries and vertebral arteries, which…
