Systems of the human body and their functions

The human body is composed of several systems whose function is to make it work in the appropriate way to guarantee our life. In the event that some functions are not carried out or are interrupted it can have consequences for health. The systems of the human body are composed of organs that converge in a general work and are also made up of the same tissues. Here 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 are classified as primary and secondary. The primary organs are the bone marrow and the thymus, which allow lymphocytes to mature, and the secondary organs are the lymph nodes and the spleen, where the cells mature to suppress organisms that try to threaten the body. 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 is made up of the skin, hair and nails and also acts as a protector. It is made up of the largest organ in 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, it also deals with the excretion process, such as sweat in order to eliminate toxins and reduce 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 lymph, a fluid that contains white blood cells and helps fight infection, and removes excess fluid from the tissues, returning it to the blood.

Muscular system

The muscular system”s function is to allow the body to move and shape it. 40% of the human body is made up of this system, additionally it is responsible for blood movements, it works as a support for the cardiovascular and digestive system, protects vital organs, maintains stability and posture.

Circulatory system

It is made up of 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 made up of the cardiovascular system, it is perhaps the system that should be taken care of the most, especially in order to keep the heart in good condition to avoid cardiovascular problems that compromise health. For this, it is necessary that you exercise, have a balanced diet and visit your doctor regularly.

Nervous system

The nervous system is made up of 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 proper interaction. It directs both voluntary actions and the movements that we make conscious as well as involuntary ones that include vital functions such as breathing.

Osseous system

Our body is made up of 206 bones, joined by ligaments, bone tissue, tendons and cartilage. 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.

Articular system

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

Endocrine system

The endocrine system is responsible for communication through 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 to regulate metabolism, sexual function and growth.
