Get startedThe cardiovascular system is a group of organs, vessels and arteries that are interconnected to remove metabolic waste and transport nutrients and oxygen throughout our bodies. (1) Within the cardiovascular system the main organ that is involved would be the heart. The heart sits in the mediastinum cavity. (2) It is positioned medial of the […]
Imagine your on the labor and delivery floor of a hospital and you hear a loud and robust cry, signaling the birth of a new born baby. A baby’s first sounds are highly anticipated, as well as very important . Have you ever wondered why? A baby takes it’s first breath about 10 seconds after […]
Apoptosis is an event in which a cell is programmed and specifically sentenced to death. It happens naturally in the body. Apoptosis in greek means to fall off, and that’s one way to think about it. It’s as if one, or a few chosen cells are falling off a cliff, while the rest keep working. […]
The immune system as a protection against infections from foreign macromolecules or attacks by organisms, including viruses, bacteria, protozoa and parasites. The immune system also plays a role in resistance to body proteins and other molecules such as those that occur in autoimmunity, and against cells that are aerated into tumors. The ability of the […]
The Immune system is a structure of body safeguarding to protect human body from antigens such as infectious and venomous agents . This system concedes, processes, and then eliminates antigens. Based on the descriptions and memory, the immune system deterrent is categorized into two which are the innate and adaptive immunity. The coordination and development […]
Humans are exposed with microbes that contain a vast array of allergenic substances that threaten normal homeostasis. Therefore, immune system is important to defend body from pathogens. It is eliminating pathological microbes and toxic or allergenic proteins, but at the same time it must avoid responses that produce excessive damage of self-tissues or that might […]
Necrosis is classified as a disorganized cell death process in response to disease, cell injury, or lack of sufficient blood supply. Changes within the structure that indicate possible necrosis include “dense clumping and progressive disruption both genetic material and of plasma and organelle membranes (Understanding Pathophysiology).” Forms of necrosis include coagulative necrosis due to chemical […]
This system consists of “the nose, pharynx, larynx, trachea, bronchi and their smaller branches, and the lungs which contain the alveoli” IMarieb, 2015). The nose is superior to the mouth. The pharynx is posterior to the nasal and oral cavities. The larynx is inferior to the pharynx and connects the pharynx to the trachea. The […]
As individuals age, the heart’s walls often grow thicker. The left ventricle’s walls become notably larger and thicker especially (Strait & Lakatta, 2012). When the left ventricle’s walls are thickened in an older adult, the ventricle is not able to hold as much blood as it would in a younger heart. It also makes the […]
Asthma is an inflammatory disease which makes breathing and some physical activities challenging and in some cases, impossible. The Greek meaning of “asthma is short of breath. However, this classifies any short-winded patient as asthmatic. This definition was refined in the 19th century by Henry Hyde Salter, who was also asthmatic. He narrowed down the […]
The cGAS is an innate immune sensor that detects double-stranded DNA. Detection of foreign DNA is an evolutionarily conserved mechanism that alerts the host immune system to mount a defense response to pathogen infections. But, there is also a challenging side for the host that how they distinguish the foreign DNA with the much abundant […]
The respiratory system is a group of organs and structures that helps us breathe. It is made up of the lungs, airways, muscles, and linked blood vessels. The airways are the pipes that both carry oxygen-rich air to the lungs and carry carbon dioxide out of the lungs. These include the nose and linked air […]
This 63-year-old man’s history revealed that his father that died from a myocardial infarction (MI) which is the result of immediate occlusion of the blood flow to the coronary vessels. The most common causes of death from an MI are decreased cardiac output, fibrillation of the heart, rupture of the heart and pooling of the […]
The respiratory system, also known as the pulmonary system, consists of all organs involved with breathing. The organs included are the nose, pharynx, larynx, trachea, bronchi, and lungs. The respiratory system does two very important things. First, it brings oxygen into our bodies. We need oxygen for our cells to function properly. Secondly, it helps […]
The two common types of cellular death are necrosis and apoptosis. Necrosis describes the changes of a cell that happen after a specified area of cell death and cellular self-digestion occur. Necrosis is an an accidental cell death which occurs because of the swelling and bursting of the cell. When a supply of oxygen is […]
Systemic Lupus Erythematous (SLE) Systemic Lupus Erythematous (SLE) is a complex chronic autoimmune inflammatory disease of unknown cause, characterized by a variety of autoantibodies that attack self-components but mostly characterized by autoantibodies that attack nuclear antigens (McCance & Huether, 2014). Explain why the pathology is a possibility for this patient. Why do the clinical manifestations this […]
The human body is comprised of multiple separate systems that work together to maintain homeostasis, regular, stable internal conditions. The maintenance of internal function depends on a variety of variables: body temperature, fluid balance, concentration of sodium, potassium and calcium ions, and blood sugar levels. The respiratory system is responsible for the function of a […]
The respiratory system is a system that is responsible for a few things. The respiratory system is responsible for the swallowing, speech, and most importantly the breathing. The body must inhale the oxygen and exhale the carbon dioxide. The respiratory system has the responsibility of getting the oxygen to the blood. The oxygen must enter […]
The respiratory system is the bodies system that introduces gases into the body and releases waste gases through breathing. The main function is to transport air into the lungs, facilitate the diffusion of oxygen into the blood stream, and exhale carbon dioxide from the blood through exhaling. The respiratory system consists of all the organs […]
The body undergoes various changes due to occurrences from the external environment, The Cardiovascular system consists of blood that plays a major role in preserving homeostasis by transporting substances to cells. The Respiratory system consists of organs that use breathing mechanism to transport the required gas via blood. Homeostasis: It is a process controlled by […]
