Human Anatomy and Physiology : V. Circulatory System Part-I

A pacemaker uses low-energy electrical pulses to prompt the heart to beat at a normal rate. It can also monitor breathing, blood temperature, and other factors to adjust the heart rate accordingly.

Pacemakers are usually implanted in the chest, often under the skin near the collarbone. There are different types of pacemakers, including single-chamber, dual-chamber, and biventricular pacemakers, each designed to address specific heart rhythm problems.

Blood is one of the most important components of life. Almost any animal that possesses a circulatory system has blood. From an evolutionary perspective, blood was speculated to have risen from a type of cell that was responsible for phagocytosis and nutrition. Billions of years later, blood and the circulatory system have drastically helped the evolution of more complex lifeforms. There are many cellular structures in the composition of blood. When a sample of blood is spun in a centrifuge machine, they separate into the following constituents: Plasma, buffy coat, and erythrocytes.
