: Submit a draft of your final PowerPoint presentation based on the information that you identified in Milestones One and Two to the discussion board  to be reviewed by your fellow classmates. You will also provide a review for at least two other classmates’ draft presentations. Use the critical element  information in the final project document for your evaluations. The purpose of this peer review in this course is not only to help your classmate to improve his or  her presentation, but to strengthen your own critical-thinking abilities by providing constructive reviews of others’ work. The basis of your response is evaluated  for the critical elements described below and in the grading rubric. Remember, this rubric assesses your performance in this activity, not the material of your  peers. This milestone will be submitted in Module Five.  Specifically, the following critical elements must be addressed:  1. Strengths: Provide feedback on the strengths of the peer’s presentation, explaining your reasoning using specific and relevant details. 2. Improvements: Provide feedback on aspects of the peer’s presentation that could be improved, using a positive tone and providing concrete  suggestions.  3. Responses to classmate presentation: Respond to questions or comments from your peers on your review of their work.  4. Responses to own presentation: Respond to the reviews of your own presentation, asking for clarification and/or answering questions and  specifically addressing comments.  

Respiratory System Discussion

Student Name




The respiratory system focuses on the trachea, bronchi, bronchioles, and alveoli and it incorporates the breathing activity to take in oxygen and take out carbon IV oxide in human beings.

The respiratory system is located in the thorax anatomically.

The respiratory system is divided into the upper and lower respiratory tract although the focus is mainly on the lower respiratory tract.

The upper respiratory tract is made up of the nose, larynx, and pharynx. The lower respiratory tract comprises the bronchi, bronchioles, alveolar duct, alveoli, and trachea.

The respiratory system has two basic structures that enable it to conduct its functions effectively. The two basic structures are the conducting portion and the respiratory portion (Paxton, n.d.).

The main function of the conducting portion is to condition the inspired air by humidifying, warming, and filtering it.

The respiratory system creates a platform for the passive exchange of gases between the blood and the atmosphere.

The respiratory system has four main layers namely; the respiratory mucosa, cartilage and/or muscle layer, submucosa, and adventitia (Paxton, n.d.).

The respiratory system may be affected by respiratory system diseases such as emphysema. The illness leads to inflation of the alveoli thus breaking their walls. That decreases respiratory function and breathlessness.

Some facts that are not well-known about the respiratory system include; people lose a lot of water through breathing, the lungs are the only body organs that can float on water, and chest movement during breathing is not a result of the air movement (Castro, 2014).

Organ System Interrelationship

Student Name




The primary organ system selected was the respiratory system.

The secondary organ system that will be discussed is the cardiovascular system which is also known as the circulatory system.

The respiratory system comprises the nose, bronchi, bronchioles, alveolar duct, alveoli, and trachea. 

The two-body systems are located in the thoracic region

The cardiovascular system comprises the blood, the heart, and the blood vessels.

The heart is responsible for pumping blood all over the body.

The oxygenated blood is brought to the body organs and the de-oxygenated blood is taken from the body organs through the blood vessels which form part of the cardiovascular system. 

Thus, the respiratory system plays a crucial role in ensuring that de-oxygenated blood is oxygenated. On the other hand, the cardiovascular system plays a crucial role in ensuring that the oxygenated blood is circulated to the body organs and the de-oxygenated blood is ferried to the lungs (Lehrer et al., 2020). 

Thus, the two systems work together to ensure that all the other body parts have oxygen to promote their effective working. 

Thus, the two systems work together to maintain homeostasis in constant exchange.

There are numerous blood vessels in the lungs to enable them to absorb oxygenated blood into the circulatory system to be delivered to other body parts.

The respiratory system creates a platform for the passive exchange of gases between the blood and the atmosphere. 

One illness that affects the respiratory system is a chronic obstructive pulmonary disease.

It is an inflammatory illness that causes the lungs to swell due to obstructed airflow from the lungs.

Examples of its common symptoms include cough, difficulty in breathing, unintended weight loss, lack of energy, swelling in feet, ankles, or legs, mucus production, and wheezing (Eapen et al., 2017).

It is caused by long-term exposure to particulate matter due to cigarette smoking or irritating gases

The illness increases the risk of getting lung cancer, depression, respiratory infections, high blood pressure in lung arteries, and heart disease. 

It is mostly caused by chronic bronchitis and Emphysema

The common risk factors are genetics, occupational exposure to duct and chemicals, exposure to tobacco smoke, exposure to fumes from burning fuel, and people with asthma.

The prevention measures that can be taken include quitting smoking and getting an annual flu vaccination and regular vaccination against pneumococcal pneumonia to reduce infection risks (Kopsaftis et al., 2018)
