Left ventricle

Introduction: The heart rate of an animal can be used as an indicator to identify when a stimulus evokes a reaction from the animal. Specifically in the case of humans’, there tends to be the cognitive ability to physically withhold a reaction from a stimulus and mask the involuntary reaction. However, the heart rate reacts immediately after a stimulus, and is not reigned in or controlled cognitively, so could the heart potentially be a true indicator of an individuals reaction to a stimulus?…

Congestive Heart Failure The heart is fundamentally a blood pump. It pumps blood from the right side of the heart to the lungs to pick up oxygen. The oxygenated blood returns to the left side of the heart. The left side of the heart then pumps blood into the circulatory system of blood vessels that carry blood throughout the body. Heart failure is an illness in which the pumping action of the heart becomes less and less powerful. When this happens, blood does not move efficiently through the…

During one year, the heart initiates approximately 32 million heartbeats to pump blood around the body, beating a total of 60-80 times per minute at a normal pace. It is a highly efficient organ and constantly works to keep our blood circulation going and ourselves alive. The high efficiency of the heart pumping system originates in a conductive system, which is linked to the Sinoatrial (S-A) and Atrioventricular (A-V) node. The Sinoatrial node, also known as the natural cardiac pacemaker, is…

that the pathways in the lungs were narrowed and the pressure increased. The right ventricle (which is responsible for moving blood into the lungs) would have an increase in work and become hypertrophic. While sometimes ventricular hypertrophy is the result of athletic endeavor and allows for more contractility; hypertrophy in pulmonary hypertension will eventually lead to a weakened ventricle and failure of the ventricle. This leads the list of complications seen in pulmonary hypertension.…

2. Physiology Q=(P1 - P2)/ R Q= flow The amount of a liquid moving past a point in a given amount of time. P=Pressure (P1-P2) The amount of force placed on an artery at any given point in time. R= resistance Is the force that must be overcome for flow to occur. Describe the basic flow equation and resistance equation as they relate to vascular flow. b. Define Poiseuille’s Equation, and describe the effect on blood flow of a change in each variable. Poiseuille's equation states that the…

What side of the heart is affected by congestive heart failure (right, left, or both)? At the point when the right half of the heart starts to work less effectively, it can't pump much blood into the vessels of the lungs. Would Fluid accumulate somewhere? If so, Where? Explain your answer. Yes, Congestive heart failure (CHF) happens when the heart's pumping activity turns out to be weak to the point that liquid starts to amass in the lungs and other body tissues. This li quid development is…

In order to assess if the full effect of anaesthesia has taken effect, the rat’s pedal reflex will be tested. Essentially, after a given period of time (approximately 5-10 minutes) after administration of anesthesia, the foot of the rat will be pinched. If the animal flinches or responds with a sudden jerk, the anesthesia has not fully taken effect and additional time or dosage is required to put the animal under. If there is no response, the animal is ready for surgery. Approximately 3-5 rats…

The “Dating Game” was a game show where an individual was allowed to ask a series of questions to three potential dates. The person asking the questions could not see his/her potential dates. Their final selection was based solely on how the questions were answered and not what they could see. The “Dating Game” concept is a good basis for the interview process used to select the right people when hiring a new employee. Interviews should be conducted with appropriate questions asked to assess…

I would start drawing conclusions on why I think the experiment turned out that way. A hypothesis is a lot to take in. My hypothesis would be that the number of Right-Handed people were most likely to be Right handed dominant. And that Left-handed people were left-handed dominant. Read a scientific research paper in a scientific journal. Identify the parts of the paper that address aspects of the scientific method. Find the parts that would be considered the abstract, background information…

From chemistry lab reports to an English essay, academic writing is a big role in the educational system. Academic writing is difficult to actually define, however the broad idea of it is about carrying a conversation forward. Academic writing is mostly preformed in essays, research papers, academic journal, etc. Some characteristics of this writing includes planning and outlining. A proper outline is crucial for academic writing. Not only will outlining help the writer formulate thoughts, but…
