Anatomy Diagram of the Human Body

Human Body Anatomy IllustrationWhat is Anatomy?

Before you can understand an anatomy diagram of the human body systems, it is important to know a little about what exactly anatomy is.

Over the past few thousand years, most of mankind’s knowledge of the human body has come from dissections and examinations of dead bodies of humans and animals. The word ‘anatomy‘ is derived from the Greek language and literally means to separate apart; to cut open and cut up. Today, the term anatomy refers to the study of the structure of all living things. Anatomy is considered a branch of biology and medicine.

The Study of Anatomy Consists of Two Primary Types of Anatomy:

1. Gross Anatomy

Gross anatomy or macroscopic anatomy is the study of structures that can be seen with the naked human eye without the aid of any special equipment. Gross anatomy is less commonly referred to as topographical anatomy, regional anatomy, and anthropotomy. A muscle anatomy diagram of human body would be considered gross anatomy.

2. Microscopic Anatomy


Microscopic anatomy is the study of structures which can only be observed through a microscope. Today our knowledge of microscopic anatomy is greatly improved thanks to modern technology such as the X-ray, ultrasound, and magnetic resonance imaging (MRI). Branches of microscopic anatomy include histology, which is the study of tissues, and cytology, which is the study of cells.

What Kind of Anatomy Diagram of the Human Body Are You Looking for?

Since there are so many different systems and the human body is so complex, each anatomy diagram of the human body will be specialized by body system. The most obvious anatomy diagram of the human body is the integumentary system, composed of the skin, hair, and nails. In this case, any photo of a human being without clothes can serve as an anatomy diagram of the human body’s integumenatary system.

One of the more common anatomy diagrams is the human muscular system. If you are just starting to learn anatomy, looking for a starter muscle diagram of the human body will lead you to soon discover that there are superficial muscles, muscles visible on the outside of the body, and deep muscles, the muscles deeper inside the body which are covered by the more superficial muscles.

Integumentary System

The integumentary system gets its name from the Latin word integumentum, which means “to cover”. The integumenary system consists of your skin, hair, and nails, which serve to protect your body against the environment, excrete waste through sweating, regulate body temperature, and synthesize vitamin D.

Muscular System

The muscular system is composed not only of the striated skeletal muscles and their associated tendons that help move your body, but also the smooth muscles in your digestive tract and arteries as well as the cardiac muscle in your heart.

Circulatory System

The circulatory system is composed of the cardiovascular system, which distributes blood, and the lymphatic system (also part of immune system) which distributes water. Your body’s veins, venules, arteries, arterioles and capillaries make up the circulatory system that you would see on an anatomy diagram of the human body.

Respiratory System

The respiratory system consists of the lungs, airways, and muscles associated with breathing, such as the diaphragm.

Digestive System

The digestive system consists of the human gastrointestinal tract (stomach & intestines), the accessory organs (salivary glands, liver, gallbladder & pancreas) and structures leading from the mouth to the anus.

Nervous System

The nervous system consists of many subdivisions. The Central Nervous System (CNS) contains the brain and spinal cord. The peripheral nervous system consists of somatic (voluntary) and autonomic (involuntary) nervous systems. The autonomic nervous system can be further broken down into the sympathetic and parasympathetic nervous systems.

Skeletal System

The skeletal system provides structure and leverage for human movement. The skeletal system is made up of the 206 bones of the human body and the associated cartilages.

Immune System

The immune system may be the most complex system in the body, because it depends on parts of almost all the other systems of the body to function correctly. The immune system’s responsibility is to detect and destroy pathogens that invade the body, such as viruses, bacteria, fungi, worms and more.

Excretory System

The excretory system, including the urinary system, consists of various organs such as the skin, lungs, urinary bladder, urethra, ureter and kidneys. It is a passive anatomical system which removes unnecessary materials in the form of gases, liquids and solids (sometimes dangerous) from the human body which helps maintain homeostasis or balance and prevents damage to the body.

Reproductive System

The reproductive system consists of the internal and external sexual organs responsible for reproduction. Unlike most of the bodily systems listed previously, males and females have significantly different components to their reproductive systems.

Endocrine System

The endocrine system is made up of glands throughout the body which produce & secrete hormones in the blood stream. These hormones have many different affects all over the body, including within the brain.
