Answer:
blood
Explanation:
Alveoli are microscopic spaces of the lung where oxygen is exchanged for carbon dioxide, at the end of the bronchi; Each lung has millions of alveoli.
The Pulmonary Alveoli are the places where hematosis or gas exchange between the blood and the lungs is performed, that is, it is an exchange of gases and not of blood. Hematosis is the exchange of gases between the lung and the blood that is produced by osmosis at the level of the alveolar sacs of each lung. In this process, CO2 passes from the arterial capillaries into the alveolar sac and O2 from the alveolar sac to the Venous capillaries producing decarboxylation and oxygenation of the blood. This gas exchange is produced by a simple difference in pressure and concentration called diffusion (from where there is more to where there is less), and implies a phenomenon of passive diffusion.
An elite runner who lives and trains in Colorado is traveling to Florida to participate in an international competition. When should she plan to arrive in Florida to make sure that she is acclimated for the change in environment?
A. 1 to 2 days before the eventB. 7 days before the eventC. 14 days before the eventD. 1 month before the event
Answer:
C. 14 days before the event
Explanation:
Based on the information provided within the question it can be said that the elite runner should arrive about 14 days before the event. This is because new climate acclimatization usually happens in a period of two weeks if the individual is completely healthy. This process may vary on the climate as well, since it is faster when the new climate is heat as opposed to cold. Therefore to be safe and ready for the competition the runner should arrive at least 14 days before the event.

As you use alcohol do the automatic functions of the body controlled by the brain like the heartbeat and breathing also become impaired?
Answer:
Yes they do become impaired
Explanation:
In your heart:
Alcohol acts as a vasodilator and causes the peripheral blood vessels to relax resulting in increased peripheral blood flow and in turn a drop in blood pressure. For the body to keep sufficient blood flow to organs, it increases the heart rate and breathing rate
In the brain:
The alcohol is absorbed in the bloodstream and goes to the nrain where it can cause impaired cognitive function which can cause deterioration in the long term

A nurse is auscultating the lung sounds of a client who came to the clinic for a physical exam.
The given question is incomplete. The complete question is as follows:
A nurse is auscultating the lung sounds of a client who came to the clinic for a physical exam. There is not any history of lung disease. What should the nurse expect to hear?
a. adventitious breath sounds
b. bronchial breath sounds
c. bronchovesicular breath sounds
d. vesicular breath sounds

A 59-year-old male with a history of emphysema complains of an acute worsening of his dyspnea and pleuritic chest pain following a forceful cough. Your assessment reveals that he has a barrel-shaped chest, unilaterally diminished breath sounds, and tachycardia. What is the MOST likely cause of this patient's condition?Select one:
A. Exacerbation of his COPDB. Acute pulmonary embolismC. Spontaneous pneumothoraxD. Rupture of the diaphragm
The most likely cause of the patient's condition, considering the given symptoms and his history of emphysema, is Spontaneous Pneumothorax. It is likely that a forceful cough caused air to leak into the space between the lung and chest wall, leading to a lung collapse.
Explanation:The MOST likely cause of the patient's condition, given the acute worsening of his dyspnea and pleuritic chest pain following a forceful cough, is C. Spontaneous pneumothorax. A person with emphysema has weakened lung tissues that are prone to rupture and can lead to a pneumothorax. This happens when air leaks into the space between your lung and chest wall, pushing on the outside of your lung and making it collapse. The symptoms outlined: barrel-shaped chest, unilaterally diminished breath sounds, and tachycardia, are classic indications of a pneumothorax. Thus, in this case, it seems like an independent event was triggered by a forceful cough, causing the emphysema to worsen into a spontaneous pneumothorax.

The most likely cause of the patient's condition is spontaneous pneumothorax. Symptoms align with the clinical features of a pneumothorax, and a forceful cough can exacerbate the condition. Immediate medical attention is essential as it can be life-threatening.
Explanation:The most likely cause of the patient's condition is spontaneous pneumothorax. Spontaneous pneumothorax occurs when there is an abnormal collection of air in the space between the lungs and the chest wall, leading to a collapsed lung. This condition is commonly seen in individuals with emphysema, as the damaged lung tissue is more susceptible to air leaks.
In this case, the patient's symptoms, such as worsening dyspnea, pleuritic chest pain, barrel-shaped chest, unilaterally diminished breath sounds, and tachycardia, align with the clinical features of a pneumothorax. It is important to note that a forceful cough can result in increased pressure within the chest, potentially causing an exacerbation of a pneumothorax.
It is crucial for the patient to seek immediate medical attention as spontaneous pneumothorax can be a life-threatening condition. Treatment options may include chest tube placement or surgery.

Muscle contusion is the injury caused by the mechanical damaging force that occurs without breaking the skin and can cause bruising or crushing or hide other serious internal injuries. The effects of a blunt blow vary according to the force and energy applied to the organism, resulting in a superficial lesion, such as ecchymosis, or injuries to organs and viscera that can compromise the life of the subject, such as a bruise or fracture.
The way to proceed with a bruise is similar in all three cases. It is convenient to apply cold, without direct contact with the skin, for twenty minutes every hour. If the affected area is a limb, it will remain raised above the height of the heart. In third grade, it should be immobilized as if it were a bone lesion. Hematomas should never be manipulated.

In terms of the processes of memory, _____ refers to transforming the information into a form that can be stored in memory.
Answer: encoding
Explanation:
Encoding can be defined as the process which involves the conversion of data from one form to another which can only be deciphered or decoded by the owner. This is done for the purpose of securing the data from theft and piracy. In this process the symbols in the data are mapped into the form of bytes. The encoding is of several types like character encoding, image encoding, video encoding and audio encoding.
Encoding is the process of transforming information into a form that can be stored in memory. It involves labeling or coding sensory information and organizing it with other similar information. This is the first stage in the Atkinson-Shiffrin model of memory.
Explanation:In terms of memory processes, encoding refers to transforming the information into a form that can be stored in memory. Encoding is the act of getting information into our memory system, which can occur through automatic or effortful processing. Once we receive sensory information from the environment, our brains label or code it. We organize the information with other similar information and connect new concepts to existing concepts.
According to the Atkinson-Shiffrin model of memory, encoding is the first of three stages that information must pass through to be stored in long-term memory. After information is encoded, it is then stored in our memory, creating a permanent record of the information. Finally, retrieval occurs when we get the information out of storage and back into our conscious awareness
