Kehafunktsioone

Kehafunktsioone, meaning bodily functions, refers to the physiological processes that living organisms undertake to maintain life. These encompass a wide range of activities essential for survival and proper functioning.

Key bodily functions include respiration, the process of taking in oxygen and expelling carbon dioxide, which is crucial for cellular energy production. Digestion is another vital function, breaking down food into nutrients that the body can absorb and utilize. Circulation, driven by the heart, transports oxygen, nutrients, and waste products throughout the body. Excretion is the removal of metabolic waste products from the body, typically through the kidneys and intestines.

Other significant bodily functions involve the nervous system, which controls and coordinates bodily activities, and the endocrine system, which regulates processes through hormones. Growth, repair, and reproduction are also fundamental bodily functions that ensure the continuation of the species and the maintenance of tissues. Maintaining homeostasis, the stable internal environment of the body, is an overarching goal of all these functions, ensuring that conditions like temperature and pH remain within optimal ranges. Disruption of any of these core bodily functions can lead to illness or disease.
