Integumentary System This system consists of the skin, hair, nails, and sweat glands. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.

Similarly, the cardiovascular, integumentary (skin and associated structures), respiratory, and muscular systems work together to help the body maintain a stable internal temperature.

The main systems of the human body are:

• Circulatory system / Cardiovascular system:
• Digestive system and Excretory system:
• Endocrine system:
• Integumentary system / Exocrine system:
• Immune system and lymphatic system:
• Muscular system:
• Nervous system:
• Renal system and Urinary system.

• Lungs. The lungs work with the heart to oxygenate blood.
• Liver. The liver is the most important organ of the metabolic system.
• Kidneys.

“It makes sense that the liver could be a nexus of metabolic control,” Dr. Gillum said. “At some level it knows more than the brain does about energy availability, and whether you’re eating too many pears.” The liver also keeps track of time.

The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body.

The brain controls the heart directly through the sympathetic and parasympathetic branches of the autonomic nervous system, which consists of multi-synaptic pathways from myocardial cells back to peripheral ganglionic neurons and further to central preganglionic and premotor neurons.

But other muscles in the body are “involuntary”, which means you can’t control them. The heart is made of a special involuntary muscle called cardiac muscle, and this muscle is made up of cells called cardiomyocytes (which literally means “heart muscle cells” in Latin).

Dopamine influences mood, being involved in the control of emotions, movement, and the appearance of pleasure. Dopamine is also on the move, with Parkinson’s disease also characterized by a deficiency of this hormone. Short-term memory also feeds dopamine, synthesized from proteins.

Psychologists once maintained that emotions were purely mental expressions generated by the brain alone. We now know that this is not true — emotions have as much to do with the heart and body as they do with the brain. Of the bodily organs, the heart plays a particularly important role in our emotional experience.
