Internal Organs Of The Human Body Anatomical Chart
The human body is a complex organism comprised of various systems and organs that work together to keep us alive and functioning. One of the most important systems in our body is the internal organ system. This system is responsible for carrying out vital functions such as digestion, respiration, and circulation.
The Brain
The brain is the control center of the body. It is responsible for processing information from the senses and controlling our movements and emotions. The brain is divided into several regions, each with its own specific function. The cerebrum is responsible for thought and movement, the cerebellum controls coordination and balance, and the brainstem regulates basic functions such as breathing and heart rate.
The Heart
The heart is a vital organ that pumps blood throughout the body. It is divided into four chambers, the left and right atria and ventricles. The heart is responsible for delivering oxygen and nutrients to the body's tissues and removing waste products.
The Lungs
The lungs are responsible for breathing, which is the process of taking in oxygen and expelling carbon dioxide. The lungs are composed of a network of tubes and sacs that are surrounded by blood vessels. When we inhale, oxygen enters the lungs and is carried by the blood to the rest of the body. When we exhale, carbon dioxide is expelled from the body.
The Liver
The liver is the largest organ in the body and is responsible for detoxifying the blood, producing bile, and storing glucose. The liver is also involved in the metabolism of fats, proteins, and carbohydrates.
The Stomach
The stomach is responsible for breaking down food into smaller pieces and mixing it with digestive juices. The stomach is composed of several layers of muscle that contract and relax to move food through the digestive system.
The Intestines
The intestines are responsible for absorbing nutrients from the food we eat. The small intestine is where most of the absorption takes place, while the large intestine is responsible for absorbing water and electrolytes.
The Kidneys
The kidneys are responsible for filtering waste products from the blood and producing urine. The kidneys are composed of millions of tiny structures called nephrons, which filter the blood and remove waste products.
The Pancreas
The pancreas is responsible for producing digestive enzymes that break down carbohydrates, proteins, and fats. The pancreas also produces insulin, which is a hormone that regulates blood sugar levels.
The Spleen
The spleen is responsible for filtering blood and removing old red blood cells. The spleen also plays a role in the immune system by producing white blood cells that help fight infection.
The Bladder
The bladder is responsible for storing urine until it is expelled from the body. The bladder is composed of muscle tissue that contracts and relaxes to control the flow of urine.
The Reproductive Organs
The reproductive organs are responsible for producing and transporting sperm or eggs. In males, the testes produce sperm, while in females, the ovaries produce eggs. The sperm and eggs are transported through the reproductive system to the site of fertilization.
The Endocrine System
The endocrine system is a collection of glands that produce hormones. Hormones are chemical messengers that regulate various functions in the body, including growth, metabolism, and reproduction. The major glands of the endocrine system include the pituitary gland, thyroid gland, and adrenal glands.
The Immune System
The immune system is responsible for protecting the body against infection and disease. It is composed of various cells and tissues that work together to detect and destroy pathogens. The major components of the immune system include white blood cells, lymph nodes, and the spleen.
The Nervous System
The nervous system is responsible for transmitting signals between the brain and the rest of the body. It is composed of two major parts, the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes the nerves that connect the brain and spinal cord to the rest of the body.
The Muscular System
The muscular system is responsible for movement and maintaining posture. It is composed of three types of muscle tissue: skeletal, smooth, and cardiac. Skeletal muscles are responsible for voluntary movements, such as walking and lifting, while smooth and cardiac muscles are responsible for involuntary movements, such as digestion and heartbeats.
The Skeletal System
The skeletal system is responsible for providing support and protection for the body. It is composed of bones, cartilage, and ligaments. The skeletal system also plays a role in producing blood cells and storing minerals such as calcium and phosphorus.
The Respiratory System
The respiratory system is responsible for breathing and gas exchange. It is composed of the lungs, trachea, bronchi, and alveoli. When we inhale, oxygen enters the lungs and is carried by the blood to the rest of the body. When we exhale, carbon dioxide is expelled from the body.
The Cardiovascular System
The cardiovascular system is responsible for transporting blood throughout the body. It is composed of the heart, blood vessels, and blood. The heart pumps blood through the blood vessels, delivering oxygen and nutrients to the body's tissues and removing waste products.
The Digestive System
The digestive system is responsible for breaking down food into nutrients that can be absorbed by the body. It is composed of the mouth, esophagus, stomach, intestines, and accessory organs such as the liver and pancreas.
The Urinary System
The urinary system is responsible for removing waste products from the body. It is composed of the kidneys, ureters, bladder, and urethra. The kidneys filter waste products from the blood and produce urine, which is then transported to the bladder and expelled from the body through the urethra.
The Integumentary System
The integumentary system is responsible for protecting the body from external damage and maintaining homeostasis. It is composed of the skin, hair, nails, and sweat glands. The skin acts as a barrier against bacteria, viruses, and other harmful substances, while the sweat glands help regulate body temperature.
The Reproductive System
The reproductive system is responsible for producing and transporting sperm or eggs. In males, the testes produce sperm, while in females, the ovaries produce eggs. The sperm and eggs are transported through the reproductive system to the site of fertilization.

The endocrine system is a collection of glands that produce hormones. Hormones are chemical messengers that regulate various functions in the body, including growth, metabolism, and reproduction.
