The main systems of the body help the body move, think, protect itself, and function. Some of these systems, like the skeletal and muscular systems, work closely together to help the body work. The muscles are also an essential part of the circulatory system, as the heart muscle tissue makes the heart beat as it should.

TL; DR (too long; not read)

The body contains 11 important organized structures: the circulatory, respiratory, skeletal, muscular, digestive, hormonal, nervous, reproductive and integumentary systems, which include the skin, hair, nails, sweat and oil glands.

Frame and movement

The body's skeletal system, made up of bones, cartilage, tendons, and ligaments, provides physical support and helps protect the body's internal organs and give them structure to adhere to. The skeletal system forms the framework to which the muscles adhere and is a necessary part of movement.

The body muscles, consisting of the skeleton, visceral and heart, generate both voluntary and involuntary movements. Skeletal muscles help a person walk or run, smooth muscles, smooth muscles, or involuntary muscles, help contract hollow muscles, including the stomach, intestines, bladder, and uterus. The heart muscle, which only occurs in the heart, pumps the blood through the circulation.

Breathing, blood circulation and immune function

The circulatory system, which includes the heart, blood vessels, and arteries, distributes nutrients, hormones, and oxygen throughout the body. It also helps to expel solid wastes from the digestive system.

The lymphatic system helps keep diseases, toxins, and foreign proteins from affecting the body. The lymphatic system includes lymph nodes, lymph vessels, T cells, and B cells.

The respiratory system includes the lungs, windpipe, and nose, which collect oxygen from the air and remove carbon dioxide from the body.

Food consumption and fluid discharge

The digestive system breaks down food and turns it into energy for the body. The digestive system includes the mouth, esophagus, stomach, and large and small intestines.

The excretory system removes extra water, toxins, and cellular debris from the body. The excretory system includes the bladder, kidneys, ureters, and urethra.

Communication and reproduction

The central nervous system consists of the brain, spinal cord and nerves and transmits electrical impulses to the entire body. The nervous system produces thoughts, initiates voluntary and involuntary movements and chemically coordinates the processes of all other body systems.

The reproductive system creates new human life. Male organs include the penis, testicles, and seminal vesicles, and female organs include mammary glands, ovaries, fallopian tubes, uterus, and vagina.

Hormones - Chemical s

The endocrine system carries chemicals around the body from certain glandular secretions, including hormones. The endocrine system controls complex mental processes such as sexual drive and physical effects on the entire body, such as: B. increased heart rate or hair growth. The endocrine system includes organs such as the pituitary, adrenal, hypothalamus, thyroid, and pancreas.

Skin, hair, nails, sweat and oil glands

As the largest organ in the body, the skin is part of the integumental system, which also includes oil and sweat glands, nails and hair. The three-layer skin made up of the epidermis, dermis and subcutaneous tissue protects the internal tissue and organs of the body, retains body fluids and protects against infectious bacteria and viruses. The sweat and oil glands help the body maintain a life-sustaining body temperature and excrete waste through sweating. The hair protects the skin from ultraviolet radiation, while fingers and toenails protect against injuries and support the corresponding areas.
