In a state of hypercapnia, the accumulation of carbon dioxide in the blood causes the pH of the blood to drop, leading to a state of respiratory acidosis.

It explains how these structures function together to maintain cardiovascular health. Key concepts like cardiac output, stroke volume, preload, and afterload are defined, with emphasis on their roles in the heart's mechanical and physiological processes.

Blood supply is primarily from the internal carotid and vertebral arteries, forming the circle of Willis for collateral circulation, while drainage occurs through dural sinuses into the jugular veins.
