What are the 12 organ system of the human body?
They are Integumentary System, Skeletal System, Muscular System, Nervous System, Endocrine System, Cardiovascular System, Lymphatic System, Respiratory System, Digestive System, Urinary System, and Reproductive System (Female and Male).
How many organ systems are there?
The human body systems
We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body.
Which of the 11 organ systems is the most important in humans?
While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The human nervous system is responsible for coordinating every movement and action your body makes.
Ten major systems include the skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and the reproductive system. Body functions are the physiological or psychological functions of body systems.
The sections below will look at the five vital organs in more detail.
Organ systems are groups of organs within the body that can be thought of as working together as a unit to carry out specific tasks or functions within the body. Dividing the human body into eleven organ systems is simply a way for the human mind to organize information about what parts do what.
These organ systems allow our human body to maintain and care for itself each and every day. These 11 major organ systems of our human body are the integumentary system (skin), skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems.
Body Systems, Functions, and Organs
|Body System||Primary Function|
|Endocrine system||communication within the body using hormones made by endocrine glands|
|Lymphatic system||return lymph to blood stream, aid immune responses, form white blood cells|
|Nervous system||sensing and processing information, controlling body activities|
Although most people have two kidneys, you only need one functioning kidney to live an active, healthy life. If you have only one kidney, it's important to protect it and keep it functioning well because you don't have a second one to take over if it fails.
Certain conditions, such as having HIV, actively spreading cancer, or severe infection would exclude organ donation. Having a serious condition like cancer, HIV, diabetes, kidney disease, or heart disease can prevent you from donating as a living donor.
The skin is the body's largest organ.
Brains can work 24 hours a day with no rest.
The skin is the most sensitive organ in our body which responds to touch, temperature etc. Skin is the largest organ of our body.
*MNEMONIC MONDAY* The 11 body systems can best be remembered by the acronym MURDERS LINC. Can you name them? Muscular, Urinary, Reproductive, Digestive, Endocrine, Respiratory, Skeletal ~ Lymphatic, Integumentary, Nervous, Central.

Grade 5 students study the human body, focusing on five major organ systems - the respiratory, circulatory, digestive, excretory, and nervous sytems. In studying the structure of organs, students will learn that all living tissues are composed of different kinds of cells.
Major organ systems of the human body
|Muscular||Provides movement, support, and heat production|
|Nervous||Collects, transfers, and processes information and directs short-term change in other organ systems|
|Reproductive||Produces gametes—sex cells—and sex hormones; ultimately produces offspring|
An organ system is a group of organs that work together to perform a complex function. There are eleven organ systems in the human body. All of these are required for survival, either of the person or of the species.
The general count is 78 organs. Bones and teeth are each counted only once. Counting each bone and tooth separately increases the organ list to 315 organs.
The abdomen contains many vital organs: the stomach, the small intestine (jejunum and ileum), the large intestine (colon), the liver, the spleen, the gallbladder, the pancreas, the uterus, the fallopian tubes, the ovaries, the kidneys, the ureters, the bladder, and many blood vessels (arteries and veins).
The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy.
