An introduction to the respiratory system

How often a breath is taken and how much air is inhaled or exhaled are tightly regulated by the respiratory center in the brain.

Other Assignments of Similar Nature. The Respiratory System Writing Service Introduction The human respiratory system is a series of organs accountable for taking in oxygen and getting rid of co2. The pharynx For the anatomical description, the pharynx can be divided into three floors.

Sagittal section of the pharynx. This is due to a change in the shape of… The design of the respiratory system The human gas-exchanging organ, the lungis located in the thorax, where its delicate tissues are protected by the bony and muscular thoracic cage.

The intrinsic muscles attach to the skeletal components of the larynx itself; the extrinsic muscles join the laryngeal skeleton cranially to the hyoid bone or to the pharynx and caudally to the sternum breastbone.

Word Review List:

The largest cartilage of the larynx, the thyroid cartilageis made of two plates fused anteriorly in the midline. The acinus consists of specific air sacs called alveoli. Supply of oxygen is maintained by respiratory system.

The vocal ligaments are part of a tube, resembling an organ pipe, made of elastic tissue. The nasal cavity with its adjacent spaces is lined by a respiratory mucosa. Sound is produced by forcing air through a sagittal slit formed by the vocal cordsthe glottis.

The vestibuleat the entrance of the nose, is lined by skin that bears short thick hairs called vibrissae. The duct drains the lacrimal fluid into the nasal cavity.

In the roof of the nose, the olfactory bulb with its sensory epithelium checks the quality of the inspired air. The nose The nose is the external protuberance of an internal space, the nasal cavity.

With this knowledge, we can select the most appropriate nutritional aid for the individual involved. The passageways thus formed below each ridge are called the superior, middle, and inferior nasal meatuses.

This is secreted by visceral layer of pleura. Carbon dioxide is produced as a result of metabolic break down of carbohydrates in body and must be eliminated quickly. The arytenoid cartilages articulate with the cricoid plate and hence are able to rotate and slide to close and open the glottis.

In this way oxygen is gained and carbon dioxide is lost by the body. The main organs of the respiratory system are lungs, which perform this exchange of gases as we breathe.

Respiratory System Introduction

Use a pencil to carefully make a hole in each cup. The main organs of human respiratory system are lungs and respiratory passages. Stick a piece of blue yarn into the open end of the second blue straw. Other gases of the atmosphere have no significant role in human respiratory system.

So you will have four blood vessels attached to your heart model. Each cup represents a heart chamber. The vestibuleat the entrance of the nose, is lined by skin that bears short thick hairs called vibrissae. Its function is lubrication to prevent friction between visceral and parietal layer.

Respiratory passages or air-ways are the conducting portions of human respiratory system.Canines, like the dog in, have a respiratory rate of about 15–30 breaths per minute.

With every inhalation, air fills the lungs, and with every exhalation, air rushes back out.
