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. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.

Respiratory System and the Muscles of Inhalation and Exhalation. The muscular and nervous systems enable the involuntary breathing mechanism. The main muscles in inhalation and exhalation are the diaphragm and the intercostals (shown in blue), as well as other muscles.

The lungs have no skeletal muscles of their own. The work of breathing is done by the diaphragm, the muscles between the ribs (intercostal muscles), the muscles in the neck, and the abdominal muscles.

Your immune system is a large network of organs, white blood cells, proteins (antibodies) and chemicals. This system works together to protect you from foreign invaders (bacteria, viruses, parasites, and fungi) that cause infection, illness and disease.

The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

Examples of Organ Systems

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

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.

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.

There are 11 major organ systems in the human organism. They are the integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems. Only the reproductive system varies significantly between males and females.

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.

Outside of the nervous system, the muscular system (13.1%) was reported most often as the most difficult organ system to learn.

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).

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.

These different body systems include the skeletal, nervous, muscular, respiratory, endocrine, immune, cardiovascular/circulatory, urinary, integumentary, reproductive, and digestive systems.

To remember the order of taxa in biology (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species, [Variety]): “Dear King Philip Came Over For Good Soup” is often cited as a non-vulgar method for teaching students to memorize the taxonomic classification of system.
