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.

Why is the respiratory system is not functional until the sixth month or later?
In the womb, the baby is encased in a sack called the Amnion. This sack is filled with fluid called Amniotic fluid, so the baby is encased in water and can not breath.
The baby's blood supply is connected to that of the mother by the umbilical cord and the placenta. The baby gets its oxygen from the mother by this supply and therefore does not need to breath while it is in the womb.
Thus the respiratory system only needs to develop fully later in the pregnancy (in preparation for the baby being born - when it must take its first breath) and it is therefore not functional earlier. Babies born too soon have great respiratory problems.
Is lactate normal as an end product of anaerobic metabolism?
Yes. But we are not supposed to be anaerobic organism and this lactate will eventually converted into to carbon bi oxide and water to give us energy.
What are the two components of the respiratory system?
The two physical components are the heart and the lungs, and the two chemical components are oxygen and carbon dioxide.
What is used as a respiratory aid?
Oxygen for therapy and sometimes helium for obstructive therapy and diagnostic.
How are the respiratory and excretory system alike?
There are a few reasons why the excretory and respiratory system are alike. A couple reasons are, both systems are located in the center portion of the body and the kidneys and lungs both are similar in shape.
What parts of the respiratory system would need to be blocked to not allow any into this system?
lungs
How do the Circulatory and Respiratory Systems interact?
The heart pumps blood into the lungs where the blood is oxygenated. The blood is then returned to the heart and the newly oxygenated blood is circulated to the rest of the body.
The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen. This occurs in the lungs and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide.
You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells. The red blood cells are carried by the blood vessels to all parts of the body. The hemoglobin releases oxygen in the periphery, and picks up carbon dioxide (CO2). The CO2 attached to the hemoglobin molecules in the red blood cells is then transported to the lungs, where it diffuses across the walls into the alveoli, and is breathed out.

How many cavities does the thoracic cavity have?
The thoracic cavity is just one large cavity. It is smaller than the abdominopelvic (otherwise called just the abdominal) cavity. The thoracic cavity is called your chest.
What is the relationship between lung problems and tuberous sclerosis?
Lung problems are a part of TS, and affect women more often. Lymphangioleimyomas of the lung are common and affect about 1-4% of people with TS by interfering with normal lung function.
Which two body systems work together?
All body systems work together and are interdependent. For example, the circulatory system and the respiratory system are interdependent, because without oxygen, your heart is unable to pump blood, and without blood, your respiratory system cannot transfer oxygen. The nervous system and the immune system are interdependent because the brain signals when the immune system should activate, and the nervous system would eventually die off from infection or a virus without the immune system to protect it.
more carbon dioxide will diffuse out of the blood
How do the lungs work with other systems to keep the body healthy?
the lungs take in oxygen and all other systems need oxygen to respire and work
What is pulmonary respiration?
The mechanism of pulmonary respiration: It includes breathing movement, exchange of gases, in lungs, transport of gases by blood and exchange of gase by tissue.
What is the Cardiopulmonary system?
the cardiopulmonary system consists of your heart and lungs which are located in the thoracic cavity of the body. the cardiopulmonary system consists of your heart and lungs which are located in the thoracic cavity of the body.
What is the breathing organ of squirrel?
Just like humans, squirrels contain lungs, the major breathing organ in the respiratory system.
What are two structures that help trap dust and smoke before it enters the respiratory system?
Two structures that help trap dust and smoke before they enter the respiratory system are the nasal hairs and the mucous membranes. Nasal hairs, or vibrissae, filter larger particles from the air, while the mucous membranes lining the nasal passages produce mucus that traps smaller particles and pathogens. Together, these structures play a crucial role in protecting the lungs from irritants and contaminants.
What Oxygen molecules absorbed by moist respiratory surfaces in humans diffuse immediately into?
Endocrine glands
How do the structures in our respiratory system work together to helps us breathe?
the lungs is the basic unit structure of the human respiratory system
What is the difference between the air we breathe in and the air we breathe out?
The difference - is in the proportion of the gasses present. The air we breathe in contains about 20% Oxygen. What we breathe out has about 16% oxygen and high levels of carbon dioxide.
What is the function of metal in respiratory pigment?
The metal component of a respiratory pigment is the part that actually binds to the oxygen molecule.
Whats the cpt manual respiratory system subsection is arranged according to From nose to lungs?
The cpt manual respiratory system subsection is arranged according to anatomic site and by procedure (incision, excision).
What are the Chemical receptors that regulates unconscious breathing?
The respiratory centers that control your rate of breathing are in the brainstem or medulla.
Specialized nerve cells within the aorta and carotid arteries called peripheral chemoreceptors monitor the oxygen concentration of the blood and feed back on the respiratory centers.
Peripheral chemoreceptors also monitor the carbon dioxide concentration in the blood. In addition, a central chemoreceptor in the medulla monitors the carbon dioxide concentration in the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord; carbon dioxide diffuses easily into the CSF from the blood. If the carbon dioxide concentration gets too high, then both types of chemoreceptors signal the respiratory centers to increase the rate and depth of breathing
The peripheral and central chemoreceptors are also sensitive to the pH of the blood and CSF.
What is the one organ in the respiratory system that doesn't touch air?
The diaphragm is the organ of the respiratory system that doesn't touch air.
