Respiratory System

The respiratory system includes the lungs and the airway. The questions in this category focus mainly on the anatomical and physiological processes associated with breathing.

2,890 Questions

Which part of the respiratory system is composed of a single layer of epithelial tissues surrounded by a network of capillaries?

The alveoli in the lungs are made of a wet wall that is one cell thick with a network of capillaries to facilitate gas exchange.

What describes the role of surfactant in the respiratory system?

Surfactant helps reduce surface tension within the alveoli, thus preventing each alveolus from callapsing as air moves in and out during respiration.

Which part of the lower respiratory tract is intimately in contact with the cardiovascular system?

The lungs are intimately in contact with the cardiovascular system. The alveoli in the lungs is where gas exchange occurs from the cardiovascular system and the respiratory system.

Describe how structure of the respiratory tube change as the branches become finer?

The epithelial lining changes from pseudostratified ciliated columnar to cuboidal and simple squamous.

Is the diaphram an organ?

Diaphragm is composed of voluntary muscles and stretches to the lower-most part of rib cage. Diaphragm is the structure that separates the abdominal and thoracic cavities that is comprised of the heart, ribs, and lungs and is particularly accountable for the respiratory operations.

The diaphragm can be separated into 3 sections: the sternal, costal, and lumbar segments. The sternal part of diaphragm consists of the 2 muscular slips from the back of the xiphoid process. Conversely, the costal part combines with the transverse muscle of abdomen. It comprises of the cartilages and nearby parts of the 6 ribs placed around the thoracic cavity. Finally, the lumbar section of the diaphragm consists of lumbocostal arches as well as the crura. The diaphragm has many openings within it to permit the passage of other structures between the abdomen and the thorax. In addition to the minor ones, there are 3 important openings in the diaphragm. The names of the openings are the esophageal, aortic and infeiror vena caval, allowing corresponding structures through them.

Diaphragm is a very important organ of the human body because of the fact that it performs on various tasks which are important to keep someone living. During the process of breathing, the diaphragm contracts to add volume to the thoracic cavity, which enables the lungs to make room for more air. This phenomenon occurs in 2 diverse varieties of respiration. The first is known as abdominal respiration, where the thoracic cavity stretches downwards. The 2nd kind of respiration is referred to as thoracic respiration and enables the thoracic cavity to extend upwards.

The diaphragm also relates to many other tasks that are not connected to breathing. For instance, it is involved in actions such as vomiting and defecation. The diaphragm is involved in all these actions by enhancing the intra-abdominal stress of the human body. In vomiting, the diaphragm may also help to prevent vomiting. This is often done by the diaphragm exerting tension around the esophagus as it passes through the esophageal opening.

The most well-known related actions of the diaphragm is hiccups. These are involuntary and unanticipated contractions of the diaphragm. Cause of hiccups is the rapid rush of air inside the lungs compelling the vocal cords to shut. Despite the fact that it is well known that hiccups are usually bothersome or hard to bear, it must be considered that they're safe to the human body. Hiccups do commonly vanish rather easily after first appearing. Therefore it is simply a matter of waiting for the diaphragm to become normal.

What is the physiological process?

The physiological process deals with a living organism and all of its parts. It includes any physical and chemical parts involved with the organism.

How does the cilia in the trachea help keep the respiratory system clean?

The cilia in the trachea is same as the cilia in the nose. They both clean the air before entering our lungs. If there's no cilia, then the lungs would most likely have problems, if not dealt with quickly. Noticed how when you breathe through your mouth more often you cough more. This is because of the cilia cleaning the air and also forcing the dirty particles out of the respiratory system.

The respiratory membrane consists of what cells?

Alveolar squamous cells and Capillary endothelial cells.

Why are cilia in the trachea important?

These are tiny "fingers" which move mucous. The mucous is sticky and traps dust, pollen and other particles. Together the cilia move the mucous out of the lungs. If this didn't happen these things trapped in the mucous would cause damage to the lungs and a person would have breathing difficulties over time.

When someone is hyperventilating what should they do to control their breathing?

breathing into a bag should help regulate their breathing and calm them down

What prevents people from hoding their breath for 2 or 3 minutes?

respiration. if you dont have respiration you can hold your breath for 2 to 3 minutes or more, but before you do that you would die.Oh, and you spelt holding wrong lol.

Is 48 too high for a four month old baby's respiratory rate?

It depends a little on if the baby is active or not. Various sources, including Wikipedia, cite 25-50 breaths a minute. Your doctor should be consulted if you are concerned, and especially if the rate is at that level when the baby is not especially active, or if there are other symptoms.

Who invented breathing?

You did when you were inside the womb. Its something that you won't forget for the rest of your life.

When is intrapleural pressure most negative?

Intrapleural pressure is most negative at the completion of inspiration.

What is respiratory system is made up of?

The nose ----> meatuses--->the pharynx (throat)----->oropharynx ---> laryngopharynx passes food to the esophagus and air to the larynx.----->trachea (windpipe)---->The primary bronchi branch from the trachea to the left and right lungs---->each primary bronchus divides repeatedly into branches of smaller diameters, forming secondary (lobar) bronchi, tertiary (segmental) bronchi, and numerous orders of bronchioles (1 mm or less in diameter), including terminal bronchioles (0.5 mm in diameter) and microscopic respiratory bronchioles----->alveolar ducts are the final branches -----> alveolar duct ----> alveolus ---->the respiratory membrane (the alveolar and capillary walls) is where exchange of gases occur.

The importance of respiratory system?

The respiratory system is crucially important to us, it allows to exchange gas. meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillary by diffusion.

Two things happen external and internal respiration. External, is the action of bringing in air literally.. by just breathing. Internal, is the cellular respiration that occurs simultaneously as we breathe.

The main function of the respiratory system is to take in oxygen, for all the cells of your body, and remove carbon dioxide.
To supply the blood with oxygen.
