The Journey Has Begun...The impulse to breath begins with a cluster of neurons in the Respiratory Center of the brain located in the Medulla Oblongata. where rising levels of CO² causes the pH of the CSF to decrease (becoming acidic) and triggers inhalation. I can't handle all this pressure...In the peripheral nervous system (PNS), acetylcholine (ACh) binds to receptor sites on individual fibers of the diaphragm. When enough of these chemical signals are received by your muscle fibers, an action potential is created causing your entire diaphragm to contract. As a result, the diaphragm contracts and moves downward, and the intercostal muscles pull the rib cage outward. This causes the air pressure within the alveoli to be lower (negative pressure) than the atmospheric pressure (760mmHg).

The chest cavity expands air is sucked into the nose and enters the upper airway. The oxygen molecule gets filtered, humidified, and warmed as it passes through the Nasopharynx and Conchae by being thrashed around. Next the molecule will pass the Oropharynx of the mouth into the Laryngopharynx, passing the Epiglottis and Glottis into the Trachea of the lower airway.

Did you remember the map?From the Trachea the oxygen molecule has to make a decision to go left or right. It decides to go right and travels into the Right Main Stem Bronchus and then into the Bronchi and even smaller Bronchioles and finally into the grape like Alveoli. Keep Your Hands Inside the Vehicle At All Times!The oxygen molecule in the Alveolus is passed to the Pulmonary Capillaries through the Respiratory Membrane. Through the process of a Concentration Gradient, the concentration of PCO² (45mmgH) is higher than the PO²(40mmgH) within Pulmonary Capillaries. The oxygen molecule attaches to Hemoglobin (one of four oxygen molecules to attach to one of 280 million Hemoglobins in a Red Blood Cell (RBC)).

The oxygen molecule rides its host RBC through the Pulmonary Venules, the Superior Pulmonary Vein, and the Left Atrium, through the Bicuspid or Mitral Valve, and into the Left Ventricle.

What are similarities between human life cycle and plant life cycle?

Both human and plant life cycles involve stages of growth, reproduction, and aging. Both organisms start as a single cell or seed, undergo periods of rapid growth and development, and eventually reach maturity where they reproduce. Both also experience aging and eventually die as part of the natural life cycle.


What function do plant have in the forest in the carbon cycle?

They take it in as carbon dioxide and let our oxygen.


Is the oxygen cycle in the desert the same as the grasslands oxygen cycle?

Yes, the oxygen cycle in both the desert and grasslands follows the same fundamental process where plants release oxygen as a byproduct of photosynthesis, which is then used by animals for respiration. However, the rate of oxygen production and consumption may vary depending on the plant species present and the environmental conditions in each ecosystem.


How do you trace the path of how oxygen molecules are produced in a plant cell to how they are used in human cells.?

In a plant cell, oxygen is produced during photosynthesis when sunlight, water, and carbon dioxide are used to generate glucose and oxygen. The oxygen produced is released through the plant's stomata. In human cells, oxygen is taken in through respiration and used in cellular respiration to break down glucose and produce energy in the form of ATP. This process occurs in the mitochondria of human cells.


How does air get in a plant?

diffusion through the stomata often located in the aerial organs of the plant aka the leaves of the plant. There is a low concentration of oxygen in the air spaces between the spongy mesophyll as oxygen is constantly used by respiring plant tissue and visa versa occurs when the plant begins to photosynthesise

What is the difference between a human life cycle and a plant life cycle?

a plants life is longer and the plant can develop for items.


What is oxygen-carbon dioxide cycles?

The oxygen-carbon dioxide cycle is the process by which carbon dioxide is converted into oxygen through photosynthesis by plants, and then oxygen is converted back into carbon dioxide through respiration by living organisms. This cycle is essential for maintaining the balance of oxygen and carbon dioxide in the atmosphere, which is crucial for sustaining life on Earth.


What is the relationship between lungs of a human and the chloroplast of a greenhouse plant in the oxygen cycle?

The lungs of a human and the chloroplast of a greenhouse plant are both involved in the process of photosynthesis. In photosynthesis, plants take in carbon dioxide and produce oxygen, while humans take in oxygen and release carbon dioxide. This interdependent relationship helps maintain the balance of gases in the Earth's atmosphere.


What is the relationship between the oxygen cycle and the carbon cycle?

The carbon and oxygen cycle are related by complementary relationship. For example whenever animals and humans breath they breath in oxygen and breath out carbon. Another example is plant and trees tack in carbon for nutrients and releases oxygen.

How do you describe the movement oxygen and carbon dioxide between living things in the environment?

Oxygen is taken in by living things during respiration and released back into the environment as a byproduct. Carbon dioxide is produced during respiration and then taken in by plants during photosynthesis to produce oxygen. This continuous cycle of oxygen and carbon dioxide exchange between living things and the environment is essential for sustaining life on Earth.


How is the balance mainted between the volume of carbon dioxide and oxygen in atmosphere?

The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere

What is the name of the device in a power plant cycle that is used to remove oxygen from feedwater that is sent to the boiler?

deaerator


Why is a plant cycle important?

Because,plants give us oxygen at daytime in order to survive.While human and other animals give carbon dioxide to the plant to make their own food by the heat of the sun. Whwn the all plants died,we/all people and animals cant breath and we will died because there isn no oxygen. Thanks!i hope,i ll help!


What Way S Are They Different between human and plant?

human are breathing oxygen,they are having sense of organ ,the do invention of machines like computer,calculator and many morewhereas plants are breathing cabon dioxide ,they dont have sense of organ and they are producing fruit,vegetables ,oxygen and many natural things.
