Answer: A buffer is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases. Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis. Because all biological processes are dependent on pH, cells and organisms must maintain a specific and constant pH in order to keep their enzymes in the optimum state of protonation. This system provides the maximum buffering capacity near pH 6.86 (the pKa of H2PO4- ). Several substances serve as buffers in the body, including cell and plasma proteins, hemoglobin, phosphates, bicarbonate ions, and carbonic acid. The bicarbonate buffer is the primary buffering system of the IF surrounding the cells in tissues throughout the body.

Aortic aneurysm occurs when a circulating clot moves through the heart to the lungs, blocking an artery supplying blood to the lungs.
<h3>What is Aortic aneurysm?</h3>
- A balloon-like protrusion known as an aortic aneurysm develops in the large artery known as the aorta, which carries blood from the heart through the chest and body.
- The strain of blood pumping can tear the layers of the artery wall, enabling blood to seep in between them. Aortic aneurysms can rupture or dissect.
- The following are symptoms and warning signs of an aortic aneurysm rupture: Back or abdominal pain that comes on suddenly, is quite strong, and lasts for a long time, reduced blood pressure, fast heartbeat
- A ruptured aneurysm can be hazardous and typically fatal if there is significant internal bleeding. 8 out of 10 persons with a rupture either pass away before they reach the hospital or are not successful surgical candidates.
