Anatomy and Physiology - Energy Metabolism

4. Rowing full speed is putting maximum demands on Jim's muscles. What metabolic process is providing most of the energy for Jim’s muscles at this point and why do Jim's muscles feel like they are burning? (5 points)

Explain the physiology the cardiovascular and the digestive system in the body in relation to energy metabolism in the body. Discuss the role of energy in the body and analyse how those two body systems interrelate to perform a named functions. For distinction analyse

There is a small amount of carbon dioxide and more oxygen in the body because of gases exchange this is where oxygen form the lungs is transferred in to the blood and carried to the heart and when carbon dioxide is carried in to the lungs forms the blood and is exacted outwards by breathing. Mitochondria also need oxygen to create carbon dioxide for the body so the gas exchange can happen again. Outside the body there is a smaller amount of oxygen but it is still higher than CO2.

P4: Explain the physiology of two named body systems in relation to energy metabolism in the body

This report will discuss the work of the energy interplay system in relation to a subject’s result in the 20 metre beep test . Energy system interplay refers to the work done by the three energy systems (ATP-PC, Anaerobic and Aerobic) to provide the body with the necessary amount of adenosine triphosphate (ATP) to complete certain physical activities depending on their intensity and duration.

Explain The Physiology Of Two Named Body Systems In Relation To Energy Metabolism In The Body

Energy is expended in a number of different ways such as the stated above; resting metabolic rate, thermic effect of activity, thermic effect of feeding and adaptive thermogenesis. An individual’s energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity, what an individual drinks and eat is energy in. what an individual burns though physical activity is energy out. Body weight is maintained and stable in the state of energy balance, the chemical bonds of carbohydrates, proteins and fats in food contain chemical energy which is then transformed in the human body in multiple metabolic processes to cellular energy, heat or stored energy. An individual’s burns a certain number of calories just by breathing air and digested food. They also burn a certain number of calories through their daily routine, an important part of maintaining energy balance is the amount of physical activity an

Each single alveoli is wrapped with capillaries. Because of this, both the alveoli and capillaries are made up of a simple epithelium, which is a very thin tissue. This single layer of thin cells creates a short distance for gases to diffuse. The oxygen will then be able to move through the thin capillary walls and into the cells while the carbon dioxide passes through the thin capillary walls from the cells. The short diffusions distance allows for a rapid gas exchange. This rapid and efficient gas exchange is required so that the cells can get the energy that they need for

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

Small air sacks called alveoli are at the tips of the bronchioles. When air reaches them, the oxygen concentration is high, which causes diffusion into red blood cells travelling through pulmonary capillaries (7). The red blood cells then distribute the new oxygen to the rest of the body. When they reach the alveoli again, they exchange carbon dioxide (a form of cell waste) for new oxygen, and repeat the process. The carbon dioxide is moved through the bronchioles, bronchi, and trachea in the form of exhalation.

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside

Three different metabolic energy systems power your workouts — and your day. Here’s how each one works, and how to make the most of them all.

For diffusion and Gas Exchange to occur here they have to have a large surface area dependent on the size of the

The air we inhale enters the lungs through tubes called bronchi. These branch into the smaller brochioles and finally into tiny air sacs, the aveoli. The average lung has more that 300 million of these air sacs, which provides a combined area of more than 750 square feet for oxygen to be absorbed into the bloodstream and carbon dioxide to be expelled.

The lungs are filled with thousands of tubes branching smaller and smaller. The smallest segments are the air sacs, called alveoli. Each one has a fine mesh of capillaries. This is where the exchange of oxygen and carbon dioxide takes place.
