How Does The Body Maintain Homeostasis
All of the organs in the body maintain homeostasis. The circulatory system consisting of the heart and vessels is of vital importance. The heart pumps blood and other nutrients through the vessels to all of the other organs in the body. The heart, vessels, lungs all work together to maintain homeostasis. With out the circulatory system, no other organ could survive.
Conduction of the heart
Carried out by electrical impulses from the heart muscle( the myocardium) which causes the heart to beat. This beat is caused by the sinoatrial node firing at the top of the atrium. This natural pacemaker sends a signal to the atrioventricular node which sends the signal to the muscle fibers causing them to contract, all of this is done involuntary.
The heartbeat is a two part pumping action that takes about a second. The two phases are known as diastole and systole. The heart beat occurs about 60 to 80 times a minute when the body is at rest and beats more when the body is placed under stress.

More women than men die of heart disease and thousands of children are born each year with heart defects. In addition, nearly 81 million Americans are living with some form of cardiovascular disease, which costs an estimated $449 billion each year. As the population ages, cardiovascular disease will have an even greater human and economic impact. It is estimated that the more than 75 million Americans will be 65 years of age or older by the year 2020. (Texas Heart Institute,
Northern Pintail: Skeletal System
1436 Words | 6 PagesThe Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.
Cardiopulmonary System
486 Words | 2 PagesThe functions of the human cardiopulmonary system can be broken down into two, circulatory system and the respiratory system. The main goal of these two systems is to maintain homeostasis in our body. Homeostasis can be described as a type of condition where the internal continuity of an individual has to keep steadiness, regardless of any external changes from the outside environment. External changes from the outside environment may include factors such as excitement, stress, exercise, diet, and much more. Exercise can be carried out because the human body can endure a high level of exercise during a prolonged period of time.
Primary Care Case Study
362 Words | 2 PagesThe number of persons over the age of 65 will double by 2030. The older population may also present with comorbidities that demand more physician services. Of the 83 million people over age 62, 14 million will have diabetes, and 21 million will be obese. However, first year enrollment in medical schools has declined every year since 1980.Other conditions that will drive demand for physician services include rates of heart disease and cancer, two of the leading causes of death in the U.S. It is projected that the shortage will most affect the primary care sector of physician services.
Explain The Organs Involved In The Homeostatic System
908 Words | 4 PagesQ1 The organs involved in the homeostatic system of salt regulation are pineal gland, pituitary glands, thyroid gland ,thymus, adrenal, pancreas, ovary and testis. All our bodies removes uneeded fluid by filtering your blood through your kidney, via osmosis, to draw excess water out of your blood. This requires a balance of sodium and potassium to pull the water across the wall from the bloodstream into a collecting channel in the kidney. A high salt diet will alter this sodium balance, causing the kidneys to have reduced function and remove less water resulting in higher blood pressure.
How To Maintain Homeostasis
1856 Words | 8 PagesHomeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in and out of the body, while internal respiration is the chemical process that breaking down nutrients with oxygen to produce energy.
Explain Why Does The Body Require Continual Intake Oxygen
421 Words | 2 Pages1- Why does the body require continual intake oxygen? How does the body use oxygen? The body needs oxygen because without it, cells cannot function. The respiratory system brings in oxygen to the body, and it is circulated throughout the body via the blood in the circulatory system.
The Framingham Heart Study
694 Words | 3 PagesThe number one killer in the United States today is heart disease or also known as cardiovascular disease (U.S. National Library of Medicine, 2015). As death rates begin to rise due to cardiovascular disease, in 1948 the Framingham Heart Study became a joint project of the National Heart, Lung, and Blood Institute and Boston University to pinpoint the most common factors that play a role in cardiovascular disease and strokes (Framingham Heart Study, 2015). Over several years, the Framingham study has identified several risks factors that are believed to increase the likelihood of a person being diagnosed with cardiovascular disease. These risk factors include high blood pressure, high cholesterol levels, smoking, obesity, diabetes, and physical
Homeostasis Personal Statement
656 Words | 3 PagesLooking back to when I was studying GCSE ’s I remember fondly my science classes and recall my enthusiasm to participate and absorb the knowledge being taught by my teachers. These classes exposed me to a lot of different and amazing topics, Homeostasis being one of them which held my attention and curiosity completely. This process intrigued me due to the biological reactions that are linked between every organ, tissues and cells of our body which keep us alive.
Human Body System Research Paper
1125 Words | 5 PagesHuman body made of a combination system which able to work throughout the body and maintain a range of the body function where required cells to function. All the body system works together to maintain body function, but various systems such as nervous, digestive and endocrine systems have specific roles in homeostasis. It is related to homeostasis and actions coordinated by the hypothalamus. It is a process where the body takes part to keep the internal environment of the body at equilibrium state where can detect the changes in the external or internal environment of body. Hormones work in the body to regulate the activity of body cells where it relates to homeostasis as the presence allows the effective function of hormone in the body.
Summary: Skeletal Muscles
1789 Words | 8 PagesThe cardiac cycle is the coordination of the filling and exhausting of blood by electrical signals that cause the heart muscles to contract and unwind. The contraction of the heart is directed by a nerve drive that goes from the SA node to AV node to AV group to Purkinje fibers to the myocardium. Amid the cardiac cycle, the heart contracts by means of systole, pushing blood out of the heart, and unwinds through diastole, filling the heart with blood. Cardiomyocytes, or cardiac cells, are striated and are in charge of the pumping of the heart; they are the main muscle cells with intercalated plates. The heart's inner pacemaker controls and times the thumping of the heart by means of electrical signals.
AHA Is The Leading Cause Of Death Essay

Unfortunately Heart Disease is the leading cause of death globally, “Of the 10 leading causes of death in 2021, 9 remained the same as in 2020. Heart disease was the leading cause of death”(CDC 1). According to the National Institute of Health, in 2021 an estimated total of 2,052 million dollars was spent on researching Heart Disease.
Total Lung Capacity Essay
785 Words | 4 PagesThe heart may have the sinoatrial node (SA node) to trigger contraction, but in order for us to breath our nervous system has to signal for us to begin the process of ventilation (breathing). Our brain stem has three parts to it, but only the pons and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon dioxide (CO2).
Mammalian Heart Dissection Lab Report
1584 Words | 7 PagesThe natural pacemakers of the heart called SA (Sino-atrial) node. SA is in the grooves where the superior vena cava meets the right atrium. After SA generates electrical signals, the cardiac impulse travels across the walls of the atria causing the atria to contract. The impulses generated by the SA node are also transmitted to the atrioventricular (AV) node located in the lower part of the right atrium near the right ventricle. When the electrical signals reach the ventricle walls from pacemakers, ventricles contract and builds up the pressure which pushes blood and opens semilunar valves.
Vital Signs
985 Words | 4 PagesTaking the pulse is counting how many beats your heart puts out in a minute. The normal range for this is 60-90 beats per minute. One way to obtain a pulse is by placing you pointer finger and your middle finger on the patient’s wrist on the side where the thumb is located. The carotid artery on the side of the neck is another location. The nurse also likes to feel the pulse on the foot to indicate if there is proper circulation.
