Respiratory systems vary from species to species but the basic anatomy for Serpentes suborder is straightforward. The average Serpentes respiratory system has two external nares, two internal nares, and a nasal cavity. While Serpentes have a nose, their nose is only meant to be another pathway for respiration. They are not used to smell like a human nose is used for. Serpentes have a glottis that is a vertical slit because it is always closed. The glottis is situated right behind the tongue and…

Henry Williams is a 74 year old African American male. Mr. Williams was admitted to the hospital with an acute exacerbation of chronic obstructive pulmonary disease (COPD). Mr. Williams has a past medical history of COPD, cardiovascular disease (CVD), asthma, hearing loss with use of hearing aids, hypertension (HTN), and hyperlipidemia. He smoked one pack per day for 50 years. He quit smoking about 6 years ago. Mr. Williams was sent to the emergency department (ED) by his primary care doctor,…

Which do you think is worse for the environment, driving a gas guzzling truck or eating beef every day? You might think that the truck is going to be worse, but you cannot see greenhouse gases and judge which is going to produce more gas. Studies are finding that cows, and other livestock, produce greenhouse gases, are having measurable effects to climate change. Although cars produce a lot of carbon dioxide (CO2) , livestock emit methane (CH4) and CO2, plus contribute to climate change in…

Pigs and mammals share a number of similarities in external features. Pigs and mammals have -an umbilical cord -ears, eyes, mouth -four limbs -an anus on the exterior - a scrotal sac (male pigs) like most mammal males -hair (fur, whiskers) -teeth, tongue and two nostrils (Nose) The fetal pig does indeed have pelage and tactile. Firstly, the pelage covers most of the body such as the (dorsal, ventral, anterior, posterior etc). The pelage alsos possesses a relatively short length. Moreover,…

Prior to analyzing the optimal well-being of an individual or groups of individuals, it is vital to investigate all the various contributing factors as well as their relationships with one another. The PERMA model developed by positive psychologist Dr. Martin Seligman provides the theoretical basis to well-being essentially refers to five main contributing components namely; Positive emotions, Engagement, Relationships, Meaning and Achievements (Seligman, 2011). Essentially, the PERMA model…

Introduction: The heart plays a crucial role in the human circulatory system. The large organ pumps the blood through arteries, veins, and capillaries to distribute oxygen and nutrients to the body. The circulatory system also plays a part in removing our waste products. Humans have double circulation, meaning the blood passes through the heart twice before completing one round; this allows for the blood to be “re-pressurized”. Once the right side of the heart receives blood from the body,…

Abstract Whens humans exercise, their oxygen supply needs to be increased in order to produce the energy needed to sustain this workload. Humans will use a variety of cardio-respiratory mechanisms in order to supply and meet the oxygen levels the body needs during exercise. In this study we wanted to see how different individuals respond to exercise, specifically how long they can work and how efficiently they work. We predicted that females who exercise will have a higher relative-VO2, higher…

comes to water. We 're dependent on the day-to-day availability of fresh, clean water. We can 't survive on seawater, we can 't live underwater, and we can 't capture rainwater on our backs. We lose water through perspiration, urination, and by exhalation--we breathe out water vapor. Only by using our intelligence and ingenuity have humans managed to live in areas where water is relatively scarce, as well as places where it 's salty or frozen.” (“Humans and Water”) As a species we have shown to…

A pneumothorax is when air is present in the pleural space which results in a partial or complete collapse of a lung (Crimlisk, 2010). There are three classifications of a pneumothorax which include open, closed, and tension. An open pneumothorax occurs when an opening in the chest wall allows air to enter into the pleural space which occurs from chest traumas like stabbings and gun shots, or surgical thoracotomies (Crimlisk, 2010). A closed pneumothorax is when air accumulates in the pleural…

In Defense of SF as a High School Elective High School is the educational backbone of what will create our society at large. What studies are necessary in order to create a functioning and prosperous society? Clearly, there is an emphasis on STEAM related fields, since those lead to well paying work opportunities, but we should not forget the value of critical thinking. There is no better way to enforce our STEAM educational goals than with introducing SF as an elective for students to take in…
