Fitness? What Are The Components Of Fitness?

Transport- Transportation of oxygen, nutrients and hormones to cells and removal of metabolic wastes such as carbon dioxide, heat and nitrogenous wastes.

The respiratory system and cardiovascular work closely together to make sure that organ tissues obtain sufficient oxygen. Oxygen is vital for cellular functions. The air inhaled in and kept in the lungs is transported to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body. Moreover, the two body systems work together to get rid of waste products such as carbon dioxide. They perform in order and are frequently referred to as the cardio-respiratory system, a combined name that highlights their close connection. After carbon dioxide and oxygen move across the alveolar wall in the lungs, the carbon dioxide-poor blood, oxygen-rich moves through pulmonary veins to the left atrium of the heart.

The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.

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.

Your body requires energy in order to be able to perform tasks. Energy comes in many different forms. They are chemical, light, sound, heat and mechanical. You can get energy from different food substances i.e. glucose, fatty acids, sugars and amino acids. To be able to get the energy from these food substances energy needs to be released with oxygen. This is known as aerobic respiration. The role that energy plays in our body is the process of moving molecules in and out of our cells while breaking down the larger molecules and building new molecules. The cardiovascular system transports oxygenated blood around the body and to the cells. It will then collect the deoxygenated blood which is ready for the excretion from the cells. The cardiovascular system will deliver the nutrients oxygen and glucose via the blood stream. Oxygen is need for aerobic respiration to occur. The cardiovascular system will pump oxygen and nutrients carrying blood throughout the body. The glucose molecules that are carried by the blood are transported into the cells. Along with the oxygen that is diffused into the cells they are used in respiration to produce ATP. The respiratory system is responsible for bringing in oxygen as well as using it to burn the nutrients that we need for energy. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream

The respiratory system and the cardiovascular system work together by oxygen being inhaled by the mouth and nostrils and then the oxygen enters the respiratory system. When the oxygen enters the respiratory system, oxygen enters the alveoli which are located in the lungs and then it diffuses through the alveolar wall. After when this process is complete, it enters the cardiovascular system. The oxygen is then mixed with hemoglobin, which forms oxyhaemoglobin. The blood is then circulated all around the body. While the blood is mixed with the oxygen, a waste gas gets produced, which is carbon dioxide. The excess gas then exists out by going through the respiratory system and then it is exhaled out from the mouth.

The respiratory system provides a network of muscles and organs that helps a human breath. It brings in oxygen though inhaling and eliminates carbon dioxide through exhaling.

According to Merriam Webster, fitness is defined as “the quality or state of being fit” (n.d. 2016). This obviously has a bit of room for interpretation. What is “fit”, anyway? Everyone measures fitness differently. Some would consider themselves fit if they don’t get winded after running up a flight of stairs, others measure it by a certain amount of weight they can lift or miles they can run, some measure it by using percentages and ratios like Body Mass Index or BMI, and others

Have you ever wondered which body system helps bring oxygenated and deoxygenated blood to the heart? Well that system is called the Circulatory System or the Cardiovascular System. Have you ever wondered which body system helps bring air into the lungs? That system is called the Respiratory system. You are probably wondering why I am mentioning the Respiratory and Circulatory system? I am talking about them because, these are the two system that I am going to be comparing and contrasting in this essay.

In conclusion, the respiratory and cardiovascular systems are directly related in a complex manner, relying on one another to perform their physiological functions. Only together can both systems work to maintain the body’s internal balance, this is evident when physical demand is higher than normal. In order to meet this demand, the heart must pump more nutrient-rich blood around the body; however it needs oxygen to do this, in response the

i) identify the components of fitness required to play these sports effectively (minimum of three)

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.

In this assignment I will be explaining the physiology of the cardiovascular system and the respiratory system. Whilst explaining the two body systems I will be explaining energy production, process of cellular respiration, the role of enzymes within these body systems, the way that these systems absorb food and the products of digestion.

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.

Physical fitness has two main classifications-performance related and health related. People have different performance related requirements in accordance with their occupation but all people have the same health related requirements (The World). Then there are two types of exercise that helps tone a person’s body while increasing its endurance. These are aerobic and anaerobic. Aerobic exercise is exercise that uses the muscles and bones. Cardio activities are a good example of this, such as running or biking. This type of exercise increases the strength of a person’s heart and boosts their lung capacity. Anaerobic exercise is an intense but short amount of exercise (Payment). Since it is only for a brief amount of time, it does not require the amount of oxygen aerobic exercise does. Instead it uses glycogen which comes from the sugar in a person’s blood. An example of this exercise is weight lifting or sprinting. A person’s requires both anaerobic and aerobic exercise for good health. Simply doing a cardio work out is not healthy, and for a person to see real results there must be some activity like weight lifting (“Anaerobic”).
