Sisäelimeen

Sisäelimeen is a Finnish term that translates to "internal organ" in English. It refers to any of the organs found within the body cavities of a vertebrate, enclosed by bones or membranes. These organs are vital for life and perform a wide range of physiological functions.

The major body cavities housing sisäelimeet include the thoracic cavity, the abdominal cavity, and the pelvic cavity. The thoracic cavity, protected by the rib cage, contains the heart and lungs. The abdominal cavity, located below the diaphragm, houses organs such as the stomach, intestines, liver, pancreas, spleen, and kidneys. The pelvic cavity, situated below the abdominal cavity, contains organs like the bladder, reproductive organs, and parts of the large intestine.

Each sisäelimeen has a specific role. The heart pumps blood throughout the body, while the lungs facilitate respiration. The digestive organs break down food and absorb nutrients. The kidneys filter waste products from the blood, and the liver performs numerous metabolic functions. The reproductive organs are responsible for reproduction.

The health and proper functioning of sisäelimeet are crucial for overall well-being. Diseases or injuries affecting these organs can have severe consequences. Medical conditions related to sisäelimeet are often diagnosed through various imaging techniques, laboratory tests, and physical examinations. Treatments vary depending on the specific organ and ailment and can include medication, surgery, or lifestyle changes. The study of internal organs is a fundamental part of anatomy and physiology, essential for understanding human and animal biology.
