The Effect of Exercise on Pulse Rate
What is a Pulse
In Physiology, a pulse is where there is a recurring opening out of
the biggest blood vessels (Arteries). This is a consequence of a
coherent flow of blood being propel around the body. The muscle that
is responsible for this surge of blood is the Heart. I know that by
taking 220 and subtracting your age you can find your maximum pulse
rate, because your muscles rely on oxygen it is important that I
understand how oxygen is transported to the bodies cells. Oxygen is
picked up by haemoglobin which is contained by red blood cells. In the
lungs haemoglobin becomes ox haemoglobin and the via versa happens
when the oxygen is removed by the cells. Oxygen is also used in cell
metabolism as it is a reactant. Now I will explain a bit about cell
metabolism.
Cell Metabolism
Metabolism is a chemical process where chemical reactions take place
in the cells of a living organism, transforming energy, sustaining
there distinctiveness and duplicating. All life forms can only survive
because of many simultaneous and regulated metabolic reactions. Each
of these reactions is triggered and controlled by a particular cell
enzyme or catalyst.
Here is the formula for cell metabolism:
Glucose + Oxygen -----> Carbon Dioxide + Energy
Metabolic reactions are split up into two forms that are both
singularly recognisable, These are named anabolism and catabolism.
Anabolism, or constructive metabolism, is the process of synthesis
required for the growth of new cells and the maintenance of all
tissues. Catabolism, or destructive metabolism, is a continuous
process concerned with the production of the energy required for all
external and internal physical activity. Catabolism necessitates the
continuous continuation of a set body temperature, and the breaking
down of complex chemical units into simpler substances that can be
actively removed as waste products from the body through the Kidneys,
Intestines, Lungs and Skin.
When the anabolism process exceeds the catabolism process either
growth or weight gain occurs.
I should read the article more carefully. I answered O2 has nothing to do with cellular respiration and it is wrong. According to the article, page 5, O2 said cellular respiration requires both myself (O2) and glucose by facilitated diffusion. The correct answer is oxygen and glucose work together to produce ATP. ATP molecules are yield during cellular respiration.
Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996).
Cardiovascular Activity And How it Influences the body. Introduction: Cardiovascular fitness is a form of aerobic fitness (Neporent and Egan 1997). There are many different ways of evaluating the amount of oxygen used during cardiovascular fitness and one the methods involved is called VO2 Max. VO2 Max is the maximum amount of oxygen that the body can hold.

The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
Red blood cells deliver the oxygen to the muscles and organs of the body.
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.
To make sure it is a fair test; the procedure is repeated a couple of
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
These results make sense because the heart beats faster in order to keep the body’s cells well equipped with oxygen. For one to continue exercising for long amounts of time, cells need to create ATP in order to use energy. Oxygen must be present for the process of creating ATP, which not only explains why higher respiratory rates occur during exercise but also faster heart rates. When the heart is beating rapidly, it is distributes oxygenated blood as fast as the body n...
Our metabolism, “the totality of an organism’s chemical reactions”, manages energy usage and production of cells. We use energy constantly and our metabolism breaks down food through complex chemical reactions into energy our cells
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
As humans we need the heart to pump blood all around the body in order
body has to work harder I think that the heart will then increase at a
