Vital organs
- Brain. The brain is the body's control center.
- Heart. The heart is the most important organ of the circulatory system, which helps deliver blood to the body.
- Lungs. The lungs work with the heart to oxygenate blood.
- Liver. The liver is the most important organ of the metabolic system.
- Kidneys.
The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.
Organs
- The brain controls thoughts, memory and other organs.
- The heart pumps blood around the body.
- The lungs separate oxygen from the air and remove carbon dioxide from the blood.
- The stomach helps to digest food.
- The intestines absorb nutrients from food.
- The liver removes poisons from the blood.
Among these
78 organs, five
organs are considered as vital for survival. These include the heart, brain, kidneys, liver and lungs.

Skin is the human body's largest organ.Body organs aren't all internal like the brain or the heart. There's one we wear on the outside. Skin is our largest organ—adults carry some 8 pounds (3.6 kilograms) and 22 square feet (2 square meters) of it.
Understanding the 11 Body Organ Systems
- Circulatory.
- Lymphatic.
- Respiratory.
- Integumentary.
- Endocrine.
- Gastrointestinal.
- Urinary.
- Musculoskeletal.
Some of the easily recognisable internal organs and their associated functions are:
- The brain. The brain is the control centre of the nervous system and is located within the skull.
- The lungs.
- The liver.
- The bladder.
- The kidneys.
- The heart.
- The stomach.
- The intestines.
Here are some of the “non-vital organs”.
- Spleen. This organ sits on the left side of the abdomen, towards the back under the ribs.
- Stomach.
- Reproductive organs.
- Colon.
- Gallbladder.
- Appendix.
- Kidneys.
1.4 Basic organs of the body
- Heart – Your heart is between the two lungs at the front of your chest.
- Lungs – your lungs are sponge-like organs.
- Liver – your liver is the organ below the lungs that acts like a filter for the blood.
- Kidneys – the kidneys are also filters.
Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight. Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face.
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.
Major Organ Systems
| System | Organs in the System |
|---|
| Cardiovascular | Heart Blood vessels (arteries, capillaries, veins) |
| Respiratory | Nose Mouth Pharynx Larynx Trachea Bronchi Lungs |
| Nervous | Brain Spinal cord Nerves (both those that carry impulses to the brain and those that carry impulses from the brain to muscles and organs) |
The main systems of the human body are:
- Circulatory system / Cardiovascular system:
- Digestive system and Excretory system:
- Endocrine system:
- Integumentary system / Exocrine system:
- Immune system and lymphatic system:
- Muscular system:
- Nervous system:
- Renal system and Urinary system.
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).
Your heart is about the size of your clenched fist. It lies in the front and middle of your chest, behind and slightly to the left of your breastbone. It is a muscle that pumps blood to all parts of your body to provide it with the oxygen and nutrients in needs to function.
According to anatomy studies [50], human body parts can be divided into nine different parts by position: the head, neck, chest, abdomen, pelvis, back, hip, extremity, and trunk. In our ontology, the nine anatomical positions are regarded as the top level.
Vital OrgansThey are the heart, brain, kidneys, liver, and lungs. The locations of these five organs and several other internal organs are shown in the figure below.
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.
