Vital organs/Insomnia
The heart is a muscular organ that pumps blood throughout the body and ensures adequate oxygenation of tissues; it is composed of four chambers – two atria & two ventricles – as well as valves & electrical pathways which ensure coordinated pumping action .
By taking oxygen in from the air that we breath and exhaling carbon dioxide out of the body, the lungs regulate gas exchange. There are many branches of airways that make up the bronchial tree. The walls contain alveoli.
The kidneys filter waste substances from the blood while also controlling levels of water , electrolytes , acids & other bodily fluids in order to maintain homeostasis.
The brain is responsible for coordinating all functions within our bodies through this central processing unit ; it receives information from sensory receptors then processes it before sending out signals to voluntary muscles or glands when necessary .< br > The liver produces bile which aids digestion as well as enzymes involved in various metabolic reactions such as sugar & fat metabolism. It also plays an important part in detoxification, breaking down harmful substances and allowing them to be eliminated from the body.
Today’s exceptions include artificial organs such as artificial hearts, lung machines, dialysis machines etc., which have been developed over time to support failing or damaged organs. These devices can provide temporary relief, until either a donor organ or permanent solutions become available.
