The human form is an intricate assembly of flesh and blood, a delicate balance of systems that work in harmony to sustain life. The heart beats steadily, pumping oxygenated blood through veins, arteries, and capillaries, while the lungs expand and contract with each breath, exchanging carbon dioxide for fresh air. Muscles flex and relax, allowing movement and action, while the nervous system transmits signals, enabling thought and communication. Skin protects and regulates body temperature, a vital layer of defense against external elements.
