Pulse Rate Lab Report

The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.

The cardiovascular system is made up of blood, the heart and blood vessels which are divided into arteries, arterioles, capillaries, venules and veins. (www.livestrong.com, 2013)

Heart rate anticipatory response – this is where the heart rate starts to automatically increase before you start to exercise. The heart rate is able to increase automatically by chemical hormones, the hormones are adrenaline and noradrenaline. These hormones are found inside the brain. The reason the heart rate increase before exercise is because it prepares the muscles for exercise, the reason it prepares the muscles for exercise is because by the heart rate increase the more oxygen is getting to the muscles there fore they will not be needing a such a large oxygen supply all at once. It doesn’t only supply oxygen it supply’s nutrients, the supply of nutrients also provides energy and helps to repair the muscles after exercise. By the heart rate starting to increase gives the heart a head to start pumping hard this enables the heart to not have as much stress on it.

The cardiovascular system, which consists of the heart and blood vessels, is the circulatory systems in our body. The major function of the system is transportation; the heart is the system pump and the blood vessels are the delivery routes. The heart transport respiratory gases, nutrients, wastes, and other substances vital to the body’s homeostasis to and from the cells by using the blood as a medium.

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.

Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.

The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The

The cardiovascular system is part of the larger circulatory system, which circulates fluids throughout the body. The circulatory system includes both the cardiovascular system and the lymphatic system. The cardiovascular system moves blood throughout the body, and the lymphatic system moves lymph, which is a clear fluid that’s similar to the plasma in blood.

The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.

Cardiovascular system contains the heart, arteries, blood and blood vessels, every system has a function and the function of cardiovascular system is that it is there to transport oxygen, nutrients, hormones and waste products around the human body. The cardiovascular system would start to slow down as the

Nearly 100,000 beats per day, or about 37 million beats per year; most of the time you are unaware that your heart does this (“WebMD”). The question is, what is the difference between your resting heart rate, compared to your scared heart rate. For the age group tested (12-16 year olds) their healthy heart rates could vary between 70 and 100 beats per minute. The importance of this project is knowing if you are “pushing” yourself too hard, and to know if certain things trigger unhealthy problems, like horror movies. The hypothesis stated is, if you scare a person from a resting heart rate to a scared heart rate their heart rate will increase because adrenaline is released into the blood.

The circulatory system is by definition the system of organs and tissue, including the heart, blood, blood vessels, lymph, lymphatic vessels, and lymph glands involved in circulating blood and lymph through the body (Dictionary). However, the heart has a very specific function that is involved in the system; the heart 's function and parts will be broken down into detail in following paragraphs.

Tim Taylor, 2012) has argued that cardiovascular system referred to as the circulatory system, is composed of blood within the blood vessels and heart. The function of the heart is pumping the blood through the blood vessels of the body.

The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.
