Recommended: Effects of exercising on pulse rate

The main components of the human cardiovascular system include the heart and blood vessels. The heart beats in order to pump blood to the vessels which are responsible for circulating it to cell tissue throughout the body. During the homeostasis process, the circulatory system provides oxygen and nutrients to the cell while removing waste products from the tissue fluid such as carbon dioxide within the lungs. This process is required for cell function.
Each beat of the heart is referred to as the cardiac cycle. When the heart beats, the atria contract simultaneously followed by the ventricles contracting simultaneously, this process is known as systole. The resting phase of the four chambers between beats is referred to as diastole.
On average, the heart rate of a healthy adult is 70 beats per minute with an average resting pulse rate of 60-80 BPM. Blood entering arteries causes their walls to expand and withdraw, this process creates the pulse that can be felt close to the surface of the skin.
The hypothesis that exercise will cause the heart rate to increase will be investig...

    In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays

    In this article, it tells how an EKG scan is on grid paper and each small block, which is one millimeter (mm) long, represents 0.04 seconds and each larger box, which is five millimeters long, represents 0.2 seconds. On a EKG scan, the voltage of the heart is measured in millivolts (mV) along the y-axis. On the scan grid, ten millimeters is equal to one millivolt. According to this source, in order to calculate the beats per minute (BPM), one divides the number of number of large boxes between each heart beat (QRS wave) in 300 small boxes. However, that used for a more consistent and steady heart rate. For a more varied and irregular rhythm, one has to count the number of QRS waves in six seconds and then multiply that number by ten. For an example, if there are eight QRS waves, then the estimated heart rate would be 80

    Two heart sounds are normally heard through a stethoscope on the chest wall, "lab" "dap". The first sound can be described as soft, but resonant, and longer then the second one. This sound is associated with the closure of AV valves (atrioventricular valves) at the beginning of systole. The second sound is louder and sharp. It is associated with closure of the pulmonary and aortic valves (semilunar valves) at the beginning of diastole. There is a pause between the each set of sounds. It is a period of total heat relaxation called quiescent period.

  • The Heart Rhythm of Sinus Tachycardia

    It’s the big day of the finals and you are experiencing some anxiety. You walk in the classroom and feel like your heart is going to jump out of your chest. This is a normal response to anxiety by the body known as sinus tachycardia. The heart is like a pump and needs to be taken care of for it to work properly. The heart has its own rhythm and on an electrocardiogram (EKG) should have a synchronous pattern called sinus. The normal sinus rhythm should be around 60-100 beats per minute (LeMone, Burke & Bauldoff, 2011). There are many factors that can change the rate and rhythm of the heart. When sleeping your heart rate tends to be slower and should be slower due to the decreased work load on the heart. Something as little as being excited or exercising can cause your heart rate to increase and due to signals to your heart telling it to beat faster to supply the body with more blood and oxygen. The heart can beat over 100 beats per minute at rest, even when supine so it is important to assess for symptoms of any complications (Olhansky & Sullivan, 2013). A normal rhythm, but faster than 100 beats per minute is called sinus tachycardia (LeMone et al., 2011).

    The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.

    State: The cardiac cycle is composed of five stages which each trigger the relaxation or contraction of the atria or ventricles and direction of blood flow. Elaborate: The cardiac cycle of the heart is divided into diastole and systole stages. Diastole refers to the period of relaxation experienced by the atria and ventricles. Systole is the contraction of the atria and ventricles.

    The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...

    The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make

    The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.

    Homeostasis, what is it? Homeostasis is the balance between systems to keep living organisms alive and healthy. For an organism to maintain homeostasis its body systems must react and respond to changes in both its internal and external environments. Majority of body systems in organisms, like a respiratory or circulatory system in animals, are part of their internal environment. One body system that is very important for maintaining homeostasis and is common among many organisms is a respiratory system. The respiratory system is responsible for disposing of carbon dioxide and in taking oxygen (vice versa for plants). Some parts that make up a respiratory system are the lungs, windpipe, and cilia in animals. Another body system important to homeostasis and common among animals is a circulatory system, used for bringing nutrients like glucose and oxygen to body cells. Some parts that make up a circulatory system are a heart, blood, and tubes for the blood to travel through (veins, arteries, and capillaries) in animals. There are many more body systems important to homeostasis, but if one is disrupted it’s vital for it to be restored to normal.

  • The Heart Essay

    The heart is a very important organ in the body. It’s around the size of someone’s hand closed up together in a fist and is located in the chest between the lungs. The main purpose of the heart is to pump blood around the body ( The Structure of the Heart). The heart consists of epicardium, myocardium, and endocardium layers that protect its walls. The epicardium is the membrane of the external heart surface. The endocardium lines the interior portion of the chambers in the heart. Lastly, between these two layers and the thickest, the myocardium is made of cardiac muscles and performs the work of the heart. Collagenous and elastic fibers between the hearts walls and chambers are called fibrous skeleton (Anatomy and Physiology pg.717- 718). It functions as a structural supporter and provides electrical insulation between the atria and ventricles. This is important for timing and coordination of electrical and contractile activity.

  • Atrial Fibrillation

    A normal heart rhythm begins at the sinoatrial node and follows the hearts conduction pathway without any problems. Typically the sinoatrial node fires between 60-100 times per minute (Ignatavicius & Workman, 2013). When a person has Atrial Fibrillation, the sinoatrial node releases multiple quick impulses at a rate of 350 -600 times per minute. When this happens, the ventricles respond by beating around 120- 200 beats per minute, making it tough to identify an accurate heart rate. This arrhythmia can be the result of various things. During a normal heart beat, the electrical impulse begins at the sinoatrial node and travels down the conduction pathway until the ventricles contract. Once that happe...
