The heart is a muscular organ about the size of a fist, located in the center of the chest, slightly to the left. It consists of four chambers. The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava. The right ventricle pumps this blood to the lungs via the pulmonary artery. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. Finally, the left ventricle, which has the thickest muscular wall, pumps oxygenated blood to the rest of the body through the aorta.
The heart contains four valves that ensure blood flows in the correct direction. The tricuspid valve controls blood flow from the right atrium to the right ventricle. The pulmonary valve directs blood from the right ventricle into the pulmonary artery. The mitral valve regulates flow from the left atrium to the left ventricle. The aortic valve controls blood flow from the left ventricle into the aorta. The complete blood flow cycle is: from the body to right atrium, to right ventricle, to lungs, to left atrium, to left ventricle, and back to the body.
The liver is the largest internal organ in the human body, weighing about one and a half kilograms. It's located in the upper right portion of the abdomen, beneath the diaphragm. The liver has two main lobes: the right lobe and the left lobe. It performs numerous vital functions including metabolizing nutrients from food, producing bile for fat digestion, filtering toxins from the blood, storing vitamins and minerals, and synthesizing blood proteins. The gallbladder, which stores bile produced by the liver, is attached to the underside of the liver. The liver receives blood from two sources: the hepatic artery and the portal vein, while the hepatic vein carries blood away from the liver.
To summarize what we've learned: The heart features four chambers and four valves that ensure proper blood circulation. The left side handles oxygen-rich blood, while the right side processes deoxygenated blood. The liver, our largest internal organ, has two primary lobes and performs hundreds of vital functions including metabolism, detoxification, protein synthesis, and bile production. Both these organs work in harmony to maintain homeostasis and are absolutely essential for survival.
