What are the 11 organ systems we have and what are their functions? - Quora

The respiratory system allows air to enter the lungs and for oxygen to diffuse into the blood en route to the body's tissues. The entrance to the respiratory system can be found in the nose and the mouth, where air enters the body and then travels through the 11 human body systems and pharynx in the throat to the trachea or windpipe.


From the trachea, right and left branches, known as bronchi, carry oxygen to the alveoli, where oxygen moves into the blood, while carbon dioxide moves into the lungs to be exhaled. The alveoli are the smallest parts of the respiratory 11 human body systems and deal specifically with exchange of gases, like traders at a market.

For 11 human body systems, they receive goods, like oxygen and carbon dioxide, from other sources and then trade them in the lungs. In the following illustration, you'll find the major organs of the respiratory system, as well as an illustration of gas exchange in the alveoli on the left.

As shown in the diagram below, 11 human body systems starts at the mouth, where we ingest our food and use our saliva, teeth and tongue to bite and mash it. Male ducts and glands help deliver the sperm. Ovaries produce female sex hormones and eggs.

Other female reproductive structures serve as sites of fertilization and development. For instance, the mammary glands produce milk for the newborn.

Body Systems

Skeletal system Total number of bones in body: Stapes in the middle ear Longest bone: Femur 11 human body systems bone In an infant, there are 33 vertebrae in the vertebral column. Five of these bones eventually fuse to form the sacrum, and four other join to become the coccyx.

As a result, an adult vertebral column has 26 vertebrae. The Nervous System Nervous system consists of central nervous system includes brain and spinal cordperipheral nervous system includes cranial nerves and spinal nerves and autonomic nervous system Nerve chains on either sides of the vertebral column.

The blood in veins moves a bit 11 human body systems and at lower pressures.

At the finest level of the circulatory system, tiny blood vessels called capillaries carry blood all throughout the tissues. By passing blood flow close to every cell, the capillaries ensure efficient delivery of needed substances.


Most bleeding from superficial cuts comes from blood seeping from these tiny, often microscopic, blood vessels. In addition to oxygen and nutrients, the circulatory system also transports chemical messages, such as hormones, around the body.


This allows the adrenal glands, for example, to send messages that cause our whole body to prepare for fight or flight. Lastly, of course, the circulatory system performs the vital task of carrying waste products away from our cells.

It delivers carbon dioxide to the lungs, and other toxins to the liver and kidneys to be destroyed or excreted. All blood is 11 human body systems through the kidneys, where special filters allow dangerous substances to pass out of the bloodstream, while keeping helpful substances in.

The endocrine system allows the body to respond to environmental changes, and to other types of survival changes, such as the need to reproduce.
