The body is made up of 11 systems that work together. New discoveries about how the body's systems function and work together continue to emerge almost daily. However, a very basic and fundamental understanding of the body's integrated working parts and organ systems has been in place for centuries.

The circulatory systemtransports oxygen and nutrients to all corners of the body. It also carries away carbon dioxide and other waste products. When people talk about this organ system, they’re usually talking about the cardiovascular system at large, which includes: 1. The heart 2. Blood 3. Blood vessels (arteries and veins) The circulatory system...
The lymphatic systemis the drainage system of the body. It plays an important role in your immunity, blood pressure regulation, digestion, and other functions. This organ system carries excess fluid, proteins, fats, bacteria, and other substances away from the cells and spaces between cells. It does this using: 1. Lymph vessels 2. Lymph nodes 3. Ly...
The respiratory system is responsible for breathing, which is the controlled movement of air in and out of the body (ventilation). It also moves oxygen and carbon dioxide into and out of the bloodstream (respiration). This organ system contains the following: 1. Lungs 2. Trachea(windpipe) 3. Airways of the respiratory tree One of the least understo...
The integumentary systemis unique because it is the largest and only single-organ system in the body. It protects the body from the external environment and helps regulate body temperature. The integumentary system is the skinand all the structures in it, including: 1. Sweat glands 2. Hair follicles 3. Nails 4. Nerves
The endocrine systemmostly regulates metabolism and uses the products of digestion. Along with the nervous system and immune system, it’s generally considered one of the most complicated systems in the body. This organ system includes all the glands that secrete hormones into the bloodstream, including: 1. Adrenal 2. Gonads (ovaries and testicles) ...
The gastrointestinal (GI) systemis sometimes referred to as the gut or the digestive system. It is responsible for breaking down foods into nutrients, which the body needs for energy, growth, and cell repair. This system includes all the organs that carry food from where it enters the body to where it exits, including the following: 1. Mouth 2. Eso...
The urinary system includes: 1. Kidneys 2. Ureters 3. Bladder 4. Urethra These organs work together to filter blood and remove toxins and waste from body tissues. The removal of excess fluid through this organ system also helps regulate blood pressure.
The musculoskeletal systemprovides the framework and the engine for our movement, posture, and physical abilities. This organ system includes: 1. The skeleton 2. All the muscles, tendons, and ligaments attached to the skeleton
The nervous systemis a network that makes it possible for different parts of the body to communicate with one another. Think of it as your body’s command station. All body processes, reactions, thoughts, and movements stem from this organ system. The nervous system is incredibly detailed and includes: The Central Nervous System 1. The brain 2. The ...
The immune systemhelps the body fight against infection and other diseases. All of its organs are borrowed from other organ systems. Because of the interplay between organs from various other systems, the immune system is one of the most complicated systems of all. The primary organs of the immune system include: 1. Lymph nodes 2. Bone marrow 3. Th...
Communication among organ systems is vital if they are to work together as a team. They must be able to respond to each other and change their responses as needed to keep the body in balance. Communication among organ systems is controlled mainly by the autonomic nervous system and the endocrine system.
- Skeletal system. The skeletal system is composed of bones and cartilages. There are two parts of the skeleton; axial and appendicular. The axial skeleton consists of the bones of the head and trunk.
- Muscular system. The muscular system consists of all the body muscles. There are three muscle types; smooth, cardiac and skeletal muscles. Smooth muscle is found within walls of blood vessels and hollow organs such as the stomach or intestines.
- Cardiovascular system. The cardiovascular system is comprised of the heart and the circulatory system of blood vessels. The heart is composed of four chambers; two atria and two ventricles.
- Respiratory system. The respiratory system consists of a series of organs; the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and lungs (alveoli).
