Systems of the human body and its functions

The human body is made up of several systems whose function is to make it work in the proper way to guarantee our life. In case some functions are not carried out or interrupted they can have health consequences. The systems of the human body are composed of organs that converge in a general work and are also shaped by the same tissues. In we show you what are the systems of the human body and their functions .

Immune system

Also known as the immune system, it is composed of lymphocytes, leukocytes, antibodies, among others. Additionally, it is made up of cells, tissues and organs that are distributed throughout the body and classified as primary and secondary. The primary organs are the bone marrow and the thymus, which allow the mature lymphocytes and secondary organs to be the lymph nodes and the spleen, where the cells mature to suppress the organisms that attempt to threaten the organism. Therefore the function of the immune system is to protect our body from any infection and sometimes this protection manifests itself with fever or inflammation.

Integumentary system

The integumentary system consists of skin, hair and nails and also acts as a protector. It is composed of the most extensive organ of the human body, which is the skin. The integumentary system has the function of separating our internal organs from the external environment, through the skin, and also deals with the excretion process, as in the case of sweating with the purpose of eliminating toxins and reducing body temperature.

Lymphatic system

Like the immune system, the lymphatic system plays an important role in protecting the body. The main function of the lymphatic system is to form and mobilize the lymph, a fluid that contains white blood cells and that allows to fight against infections. It also removes the excess of this fluid from the tissues, returning it to the blood.

Muscular system

The muscular system has the function of allowing the movement of the body and giving it shape. 40% of the human body is formed by this system, is also responsible for the displacement of blood, works as a support of the cardiovascular and digestive system, protects vital organs, maintains stability and posture.

Circulatory system

It is formed by the heart, arteries, veins and capillaries. The function of the circulatory system is to mobilize blood, oxygen, carbon dioxide, hormones and nutrients. This circulatory system is also composed of the cardiovascular system, is perhaps the system that should be taken care of more, especially in order to keep the heart in good condition to avoid cardiovascular problems that compromise health. For this you need to do exercises, have a balanced diet and visit your doctor regularly.

Nervous system

The nervous system is the brain and spinal cord, and is protected by the meninges and the peripheral nervous system that contains the cranial and spinal nerves. The main function of the nervous system is to understand and process, very quickly, external signals, maintaining control of the organs for an adequate interaction. It directs the voluntary actions as well as the movements that we make conscious, as well as the involuntary ones that include vital functions such as breathing.

Osseous system

Our body is made up of 206 bones, united by the ligaments, the bone tissue, the tendons and the cartilages. The bone system has the function of supporting the structure of our body and protecting it through the bones, it also intervenes in the formation of blood cells and in the reserve of calcium.

Joint system

This system works in conjunction with the bone system and is made up of the joints and ligaments, which are the structures that connect the bones to the cartilage and the teeth. Our body has more than 200 different joints, and they have different functions, some are in charge of the movement, others to maintain or maintain the union between them.

Endocrine system

The endocrine system is responsible for communication by means of the hormones that the body secretes. It is made up of the endocrine glands, which are the pituitary, the thyroid, the thymus, the pancreas and the adrenal glands. Hormones are released into the bloodstream to regulate specific functions of the body. Among the functions of the endocrine system are regulating metabolism, sexual function and growth.
