Introduction

The respiratory system can be termed as a biological system comprising of specific structures and organs that are used, by an organism, in the respiration process. It participates in the exchange together with intake of oxygen and carbon dioxide between an organism and its environment (Seeley, Stephens and Tate).

In vertebrates that breathe air, respiration occurs in the organs of respiration, lungs. The air passage to the lungs for supply of oxygen to the body is called inhalation, while the air passage away from the lungs to release carbon dioxide is called exhalation. In human beings, the anatomical characteristics ...

What is the chemical formula for ozone gas?

Ozone is present in the troposphere, a part of the atmosphere. Ozone consist of 3 molecules of Oxygen. The chemical formula for ozone is O3. Ozone is also called as tri-oxygen since it consists of 3 molecules of oxygen bound to each other by covalent bonds. The structure and formula of ozone were identified in the year 1865. However, it is less stable than Oxygen and blue in color.

The major differences between these two types of diseases relates to the vascular components of the cardiovascular system. This simply means that the cardiovascular diseases do not only involve the heart alone but also involves all the heart linked vessels. i.e all arteries, veins and lymphatics found to be associated with the heart and blood passes to and from the heart. However, the coronary heart diseases only relate to the vessels that are within the heart itself and supply the heart itself and also the muscles of ...

- Erythrocytes or red blood cells are the most well-known components of the whole blood. They contain hemoglobin, a complex protein, which contains iron. This helps red blood cells to carry oxygen through the body. And this is the main function of erythrocytes. When hemoglobin concentrations fall down and there is no sufficient amount of red blood cells to carry oxygen it is termed anemia. Iron is very important component of the erythrocytes because iron can bind oxygen and transport it to the tissues.

Respiration is essential in the survival of all living organisms. It is a process where gas exchange occurs in all biological organisms. In the case of animals such as humans, respiration is affected by the ratio of the concentration of oxygen and carbon dioxide in the body. The human body generally requires oxygen gas because it is only through this aerobic respiration by which metabolic functions are assumed to maintain homeostasis. In humans there is a specific organ system which is solely dedicated to respiration known as the respiratory system. The human respiratory system constitutes different types of organs which performs ...

Microbial nutrition is essential in the survival and growth of microorganisms. Talaro and Chess considers several factors which are key players in the survivability of microbes in order to adapt or “inhabit all parts of the biosphere.” Among these factors include nutrients, temperature, pH, water availability, atmospheric gases, light, pressure and other organisms inhabiting the earth. Nutrition in essence is that which chemical substance in the form of nutrients are ingested inside the body such that when assimilated leads to the formation of energy to be used for metabolic activities.

There are multiple websites that aim to teach students about electrocardiograms (ECG/EKGs). One website that was quite effective is the one build by a paramedic, Aaron Segal (n.d.). One positive attribute of this site was the use of analogies and humor. Although the toilet analogy for the description of absolute and relative refractory period might be considered by some to be in poor taste, it is certainly easy to remember (Segal, n.d., Cardiac contraction and ECG). From this site I learned basic information about ECGs including how to read a normal one, the steps of interpreting an ECG, and some examples ...

1) Explain how the outward flow of energy from the Earth’s interior drives the process of plate tectonics?

The outermost layer of earth, or lithosphere, is broken up into tectonic plates. The boundaries of the plates and their movement leads to the formation of earthquakes, volcanic activity, creation of mountains, and the formation of oceanic trenches. Tectonic plates are formed from either oceanic crust or continental crust, with many containing both. The movement of the plates varies from 0-100mm in a given year. The movement of these plates comes from the outward energy of flow that comes from earth’s central core. Radioactivity produced from elements within earth’s core, such as uranium, decay and release energy. The ...

2) There are justifications on the presence of the moon. Perhaps, collision-ejection theory of the moon gives an explains on the issues. The theory asserts that the moon exists due to the formation of debris ejected from the earth, especially when objects crushed. Collision-ejection theory claims that the newly formed earth collided with mars at an angle, which splashed the layers of the earth surface into the orbit around it. This implies that the Earth crust and mantle formed the moon though condensation. There are various facts on the moon that the theory is consistent with. Some of the ...

1.Jupiter was the first. Giant lies just beyond the frost line. As the frost line accumulated great amounts of water via evaporation from infalling icy material, it created a zone of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. As a result , the frost line acted as a barrier whice lead material to accumulate. This excess material coalesced into a huge embryo of around 10 Earth masses, which then began to grow rapidly by swallowing hydrogen from the surrounding disc, reaching 150 Earth masses in only another 1000 years and finally topping out at ...

1. The cephalosporins are a family of bactericidal antibiotics structurally related to penicillin which were first derived from the fungus, Cephalosporum acremonium. 

Cephalosporins are the most frequently prescribed class for antibiotics (eMedexpert, 2011). This class’ mode of action is similar to other beta-lactam antibiotics, such as penicillins and cephamycins. Every form of bacteria cell has a certain cell wall for protection. Cephalosporins disrupt the synthesis of the peptidoglycan layer of bacterial cell walls, which makes the bacteria cell walls break down and the bacteria eventually die (eMedexpert, 2011). One intravenous (IV) drug under this class is cefazolin. For adults, dosage for ...

Report on Case 1: Diagnosis of Hereditary Fructose Intolerance

Enzymes act as biological catalysts, they speed up biological reactions and are also capable of regulation. Enzymatic reactions can be anabolic – where a new substance is built from smaller ones; or catabolic – where a substance is broken down to yield simpler molecules. In the example of fructose, enzymes catabolize this simple sugar to substances that are intermediates of the glycolytic pathway, allowing fructose, a 6-carbon sugar, to be used by cells to obtain energy in a way similar to glucose (also a 6-varbon sugar). Aldolase B is one of the enzymes involved in the catabolism of fructose, and its deficiency results in ...

As men advance in age, there are several changes that occur in their reproductive system. The changes particularly occur within the testes. The testicular mass decreases with aging. There is a decline in the levels of testosterone and as a consequence of the decline, men tend to have decreased libido and reduced number of spermatozoa. Aging in itself does not render a man sexually incompetent rather it presents several challenges to sexual performance. Some men develop erectile dysfunction although this may not necessarily be a direct consequence of aging. It may be caused by medications such as the ones used ...
