respiratory system reproductive system nervous system

respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

Exchange of oxygen and carbon-dioxide between the body and air, acid-base balance regulation, phonation.respiratory system starts at the nose and mouth and continues through the airways and the lungs. Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx. The entrance to the larynx is covered by a small flap of tissue, the epiglottis, that automatically closes during swallowing, thus preventing food or drink from entering the

reproductive system

(REE-proh-DUK-tiv SIS-tem) The tissues, glands, and organs involved in producing offspring (children). In women, the reproductive system includes the ovaries, the fallopian tubes, the uterus, the cervix, and the vagina. In men, it includes the prostate, the testes, and the penis. Production of reproductive cells and contribution towards the reproduction process.

This system is related to the production of offspring. It includes ovaries, uterus, mammary glands (breasts), penis, and testes. The reproductive system is not essential to individual survival, but it is essential for the survival of the species.

nervous systems

The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The brain is what controls all the body's functions. The spinal cord runs from the brain down through the back.

The nervous system allows us to sensory stimuli as light, sound, smell, and touch from our environment.

It also allows rapid communication of stimuli within our body, such as sensations ofpain, illness, and wellness. The nervous system accomplishes all of this using highly specialized cells called neurons, which can transmit signals extremely fast by firing electrochemical potentials.
