There is no inferior process on any vertebrae, thoracic or not. There is an inferior articular facet. The inferior articular facet would articulate with the superior articular facet of the vertebrae just superior to it.
The xyphoid process is the inferior sternal bony landmark.
Hypertrophy refers to the increase of the size of an organ, which can often be detrimental. The inferior articular process is a part of the vertebrae, and as such hypertrophy in this location can be extremely dangerous.
Pulmonary Circulation
The inferior articular process or facet of the vertebra above.
In anatomical position, the hands are indeed inferior to the xiphoid process of the sternum.
The Xiphoid Process is part of the Sternum (breast bone). It is the inferior part to which the Costal Cartillage of the False Ribs attaches. The xyphoid process, which is the inferior portion of the sternum.
The xiphoid process is the most inferior portion of the sternum. The superior section is the manubrium, and the medial portion is the body.
The blood from the body tissues arrives at the heart in vessels called the inferior and superior Vena Cavas. It enters the right atrium of the heart and is pumped passed the tricuspid valve into the right ventricle. Then a second, delayed contraction, pushes the blood through another valve, the pulmonary semilunar valve into the pulmonary trunk. From here the blood moves through the left and right pulmonary arteries and enters the left and right lungs where gas exchange takes place. Carbon dioxide is dropped off and oxygen is picked up by the hemoglobin of the blood by a process known as diffusion. Then oxygenated blood moves through the pulmonary veins to the heart and enter into the left atrium. This completes the pulmonary circuit of the cardiovascular system.

There are many section in the heart, starting with: The Superior Vena Cava, where de-oxygenated blood flows in from the body. From there the blood flows into the Right Atrium, through the Tricuspid Valve and into the Right Ventricle. After the blood is in the Right Ventricle, the blood flows out of the heart through the Inferior Vena Cava and in to the lungs, where it can be oxygenated. Once oxygenated, the blood flows back into the heart through the Pulmonary Artery. From the Pulmonary Artery the blood flows into the Left Atrium, through the Mitral Valve and into the Left Ventricle. From there the blood flows through the Pulmonary Valve to the Aorta and out into the body. The process then starts over from there.
