These 14 systems are the Musculoskeletal system; Organs of Special Sense (optical); Auditory; Infectious Diseases, Immune Disorders, and Nutritional Deficiencies; Respiratory system; Cardiovascular system; Digestive system; Genitourinary System; Hemic and Lymphatic system; Skin; Endocrine system; Neurological …

Examples of Organ Systems

• Integumentary.
• Skeletal.
• Muscular.
• Circulatory.
• Respiratory.
• Digestive.
• Urinary.
• Immune.

Some organs are in more than one system. For example, the nose is in both the respiratory system and also is a sensory organ in the nervous system. The testes and ovary are both part of the reproductive systems and endocrine systems.

• The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles.
• There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth (non-striated) muscles.

The human body consists of eleven organ systems , each of which contains several specific organs . An organ is a unique anatomic structure consisting of groups of tissues that work in concert to perform specific functions. Table 1 includes the structures and functions of these eleven organ systems .

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.

For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide.

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.

In fact, the most durable and tough substance in your body is actually a tissue. Encasing your teeth and helping you chew, bite, and tear your food is your tooth enamel. That’s the hardest substance in the human body.

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.

So here are the top five strongest muscles in the body based on these different ways to measure strength:

• Heart. The heart, which consists of cardiac muscle, is said to be the hardest working muscle in the body.
• Masseter.
• Soleus.
• Gluteus Maximus.
• Uterus.

Shevaun Doyle, Pediatric Orthopedic Surgeon, about some of the bones in your skeleton: 1. The femur bone is the longest and strongest bone in the body. Located in the thigh, it spans the hip and knee joints and helps maintain upright posture by supporting the skeleton.

Treatments ranging from casting to surgery can be required. Unfortunately, the scaphoid bone has a track record of being the slowest or one of hardest bones to heal.

The thigh bone is called a femur and not only is it the strongest bone in the body, it is also the longest. Because the femur is so strong, it takes a large force to break or fracture it – usually a car accident or a fall from high up.

Once there, the sound waves vibrate three bones known as the ossicles, which are made up of the malleus, the incus, and the stapes. The stapes is the smallest bone in the human body.

Your lower jawbone is the only bone in your head you can move. It opens and closes to let you talk and chew food. Your skull is pretty cool, but it’s changed since you were a baby.

Our data indicate that although the cranial bones move apart even with small (nominally 0.2 ml) increases in ICV, total cranial compliance depends more on fluid migration from the cranium when ICV increases are less than approximately 3% of total cranial volume.
