How do the respiratory system and the cardiovascular systems work together?
The respiration and cardio vascular work together o make the body become alive. It does this by having 2 different system working in the body. The 2 are respiration and cardio vascular system. the respiration system bring the air from outside the body through the mouth or nasal cavity. Then goes down to the Pharynx which leads up to the Epiglottis which goes passed through the larynx which goes to the trachea which goes into the lungs. In the lungs, the air goes to the bronchi which brakes down into the bronchioles
which goes into the alveoli sack where the air takes out the oxygen from the air. This is also the connected point to the cardio vascular system which it gives it the oxygen it needs to complete its job. The blood is out side the alveoli sack in a capillary. The way the gas can go through the capillary walls is because the walls of it is one cell thick which allows things to pass through. The blood flows through the capillary which widens into a venues which widens into veins which goes to the heart. The heart pumps the blood around the body. It first pumps it to the arteries which goes smaller into a arterioles which goes into a capillary. The capillary gives the oxygen to the muscle and receives it's waste products e.g. oxygen. The deoxygenated blood goes through the capillary which widens into venues which then widens into a veins which leads to the heart and gets pump into a arteries which becomes into arterioles which goes back into a capillary which give the carbon dioxide to the alveoli sack which the alveoli sends away through the bronchioles
which widens into bronchi which trachea which then goes through the larynx which then goes pass the Epiglottis which then goes through the Pharynx which goes back out through the nasal cavity or mouth.What does the Respiratoy System consist of?
pharynx, larynx, epiglottis, trachea, bronchi (lungs), bronchioles, alveoli
It then connects circulatory then back.
What happens if you breathe in dust?
Not much harm can happen if you breathe dust. Unless you have breathing problems such as Asthma. If you have no respiratory problems, the worst that can happen from breathing dust is sneezing or minor coughing
Do plants do celluar respiration?
it does use cellular resp0iration
Plants also need energy.They get energy by respiration
What terminates in a grape-like cluster in the respiratory system?
The bronchioles terminate in a grape-like cluster of alveoli in the lungs.
They are called alveoli
What is the path that oxygen follows in your repiratory system and the cardiovascular system?
The oxygen goes into you're lungs and the blood cells get the rich oxygen, and the blood cells come back with the carbon dioxide,
What do blood cells do to help the respiratory system?
the red blood cells get oxygen or put out carbon dioxide through the capillaries in the alveoli of the lungs. They do this to help get oxygen for the cells in the body/ take away carbon dioxide from the cells
What is the function of the respiratory epithelium that lines the nasal cavity?
Most of the conducting portion is lined with ciliated pseudostratified columnar epithelium known as respiratory epithelium . This epithelium has at least five cell types, all of which touch the thick basement membrane:
§ Ciliated columnar cells ) are the most abundant, each with about 300 cilia on its apical surface
MEDICAL APPLICATION
Immotile cilia syndrome, a disorder that causes infertility in men and chronic respiratory tract infections in both sexes, is caused by immobility of cilia and flagella induced, in some cases, by deficiency of dynein, a protein normally present in the cilia. Dynein participates in the ciliary movement
§ Goblet cells are also abundant in some areas of the respiratory epithelium , filled in their apical portions with granules of mucin glycoproteins.
§ Brush cells are a much more sparsely scattered and less easily found, columnar cell type, which has a small apical surface bearing a tuft of many short, blunt microvilli . Brush cells express some signal transduction components like those of gustatory cells and have afferent nerve endings on their basal surfaces and are considered to be chemosensory receptors.
§ Small granule cells are also difficult to distinguish in routine preparations, but possess numerous dense core granules 100-300 nm in diameter. Like brush cells, they represent about 3% of the total cells and are part of the diffuse neuroendocrine system
§ Basal cells, small rounded cells on the basement membrane and not extending to the luminal surface, are stem cells that give rise to the other cell types.
Respiratory potion lined by simple squamous epithelium.There are two types of neumocytes lined by alveoli type1 and type2 . Type 2 cells secrete surfactant.
Air from the outside environment first enters the respiratory system through the .?

smoking can give you 3 kinds of diseases: cancer, heart attacks, and strokes.
What are the products formed during aerobic respiration and anaerobic respiration?
The word aerobic means to use oxygen while anaerobic doesn't need oxygen. The products of aerobic respiration are carbon dioxide and water and energy (ATP). The products of anaerobic respiration are oxygen and energy (ATP).
What keep food from entering your air way?
the epiglottis closes over the glottis in a reflex action when food is swallowed. This prevent food from entering the respiratory system
Why is mucus important to our respiratory system?
Fine hair and mucus act as the first line of defense in the nasal passage. They keep foreign particles that could cause illness from entering the body. The hairs (cilia) and mucus along the nasal cavity are responsible for trapping dust and other particles in the air you inhale and sweeping it out again. They work in the same way as an air filter does on a motor vehicle's engine.
What gases are exchanged in the pulmonary circuit?
generally accepted answer - oxygen gas (O2) and carbon dioxide gas. But also water vapor, some nitrogen, and a lot of other trace gases.
What does each part of the bunch grapes model represent in relation to the breathing system?
The stems would represent the brochioli and the grapes would represent the alveoli.
Does you age affect your lung capacity?
Men have larger lung capacities than women. Tall people also have larger lung capacities than short people. It is said that people aged 20-25 have larger lung capacities than other age groups, Its because by the time you have reached your twenties your lungs have reached their full capacity, but when you are a kid then your lungs aren't fully developed so they don't have a large capacity. From when you are 20 your lung capacity starts going down so an old man has about the same lung capacity as a very small boy.
Why is the respiratory system dependent on circulating system?
The respiratory system draws oxygen into the lungs. The circulatory system moves blood into the lungs to pick up the oxygen and then brings the oxygen to cells in the rest of the body.
How do you increase pao2 with mechanical ventilation?
In manual ventilation you can increase the PaO2 by hyperventilating the patient, by increasing the respiratory rate and/or by increasing the volume of air that you deliver to the patient. If using a BVM for example, compressing the bag faster and/or harder will increase the arterial oxygen pressure, but there is a limit to what you can do with manual ventilation. Perfusion in the lungs has a major impact on PaO2. Also, the blood chenistry (anemia or CO2 poisoning) for example will dramatically decrease the PaO2. Sometimes no matter how much you hyperventilate the person, low PaO2 can't be corrected.
Where do the vast majority of pulmonary emboli originate?
where does the vast majority of pulmonary emboli orginate
1. I sneezed a sneeze into the air.
It landed I don't know where,
But long and hard were looks of those
In whose vicinity I snooze.
