Question

Define the Human Heart. only in one word​

Answer 1

• The human heart is an organ that pumps blood through the veins of the circulatory system, providing oxygen and sustenance to tissues while also removing carbon dioxide and other pollutants.
• The human heart is positioned in the middle of the chest, somewhat to the left of the sternum (breastbone).
• It is housed in the pericardium, a double-walled sac that sits between your lungs, according to the Texas Heart Institute.
• The pericardium is a membrane that surrounds and protects the heart within the chest cavity.
• Pericardial fluid, which serves as a lubricant, separates the outside layer, the parietal pericardium, from the inner layer, the serous pericardium.
• The fluid lubricates the heart during contractions and movements of the diaphragm and lungs.
