Acute And Chronic Effects On The Body System

have a variety of systems due to the complexity of the species' organism. The human body

Exercise affects these systems, causing the heart to pump blood faster around the body, which in turn allows you to exercise for longer. http://www.bbc.co.uk/schools/ gcsebitesize/pe/appliedanatomy/0_ anatomy_circulatorysys_rev1.shtml The four main parts of the cardiovascular system is the heart, the veins, capillaries and the arteries.

1. The musculoskeletal system includes bones, joints, skeletal muscles, tendons, and ligaments. The response this exercise does to the body is increased blood supply for muscles to work for longer and harder when exercising, muscle pliability will also develop as regular muscles are being used and developed making them stronger overall. Increased respiratory rate, increased fuel metabolism, increased oxygen

All the systems in the human body are vital to our survival and well-being. If you take away the functions of just one of these systems our whole body will cease to work properly. The main systems of the human body are the nervous, endocrine respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive systems. They all work together in harmony and unison to keep us alive.

Exercising stimulates Vasodilation and Vasoconstriction to facilitate the oxygen delivered to the muscles. It also keeps the blood vessels healthy and stops the accumulation of cholesterol and harmful substances. It can also help on warming up and cooling down of the

During exercise there is an increase in cardiac output, which corresponds to an increase in maximal oxygen consumption. With the increase in oxygen consumption, a greater increase in blood flow occurs. This means there is more oxygen circulating in the blood for the tissues to take up. Due to the increase in blood flow, vasoconstriction of arterioles occurs to maintain mean arterial pressure (Bassett & Edward, 1997). This limits oxygen consumption because some of the blood flow is directed to the brain and skin. It is further pointed out that the heart is another limiting factor because it determines how much blood and oxygen are supplied to the muscles especially when blood flow exceeds maximal cardiac output (Bassett & Edward,

Muscular system – The muscle system is just that – muscles. Muscles, with the support of the skeletal system, are what makes humans walk, run, or grab and lift thing by contracting and working together with other muscles and body parts. d. Nervous system – The nervous system is the fast-acting message center for the brain and spinal cord to nerves and other parts of the body. When you think to jump, this is what tells your brain and your muscles when and where to jump. Like the integumentary system, it also senses and regulates body temperature on the outside, but the nervous system also regulates and detects internal temperatures.

There many diseases and conditions that can affect the human body, that may be unpredictable. It may affect different systems of the body, and there might not be cure or treatment. The body consists of three main systems the Integumentary System, Skeletal System, and the Muscular System, which help us with our everyday lives. For example, the Integumentary System is the largest organ in the body, which provides protection from viruses and other diseases. Our skin helps regulate body temperature and eliminate waste.

These are only some examples the muscle system does. In the video, talked about the muscles cells that are also known as muscle fibers. Each muscle fiber is surrounded by an excitable membrane called a sarcolemma and bundles that receive signals from the nervous system that contact them creating force and motion; this produces almost all the movements. The skeletal muscles are connected to the somatic nervous system. This gives control to the person over their movements. In the video, “How your muscular system works,” it also went over the fast fibers and slow fibers. Fast fibers react very quickly, but it easily fatigues. On the other hand, slow fibers are slow to react and slow to fatigue. The video also mentioned the Autonomic Nervous System and that the cardiac muscle and smooth muscle. The Autonomic Nervous System contracts and relaxes the smooth muscle. For example, it pushes food through the digestive system. Also, The Autonomic Nervous System contains cardiac muscle that supplies the heart with blood and

Your musculoskeletal system (your body) is made up of hundreds of muscles and bones. Your nervous system, made up of your brain and kilometers of nerves that travel throughout the body, controls every muscle, organ and cell in your body allowing you to breathe, eat, see, move, think or exist.

Increased oxygen at the muscular level will decrease lactic acid build up. This lessens fatigue and, in turn, increases the amount of muscle you can build.

The musculoskeletal involves the muscles and skeletal system which consist of bones supporting the bodyweight. The muscles and bones help in movement and maintaining body position through the physiological process of contraction and relaxation, muscles pulling on the bones. The skeletal systems also consist of cartilages and ligaments important for bone connection and stability with connective tissue. The muscles get attached to the bone by the connective tissue enhancing contraction and relaxation in movement. The muscles contain long muscle fibers responsible for the contraction and relaxation. The fibers contain bundles some of which allow slow movement described as slow twitch and fast twitch which ensure fast movement. The process of movement involves coordination between the musculoskeletal system and nervous system. In the process of muscle contraction to enhance movement the following takes place. (Arthur Guyton, 2006)

The skeletal system, which deals with the body’s support and structure, keeps homeostasis by regulating the calcium supply in the bones. By doing this, out bones stay as healthy and as strong as possible. The muscular system, which is attached to the skeletal system, deals with the body’s movement. One way the muscular system maintains homeostasis is by sweating. If the body gets to hot and needs to cool down, it produces sweat which allows the skin cool down. Next, comes the endocrine system. This system is a collection of glands, which produce hormones to basically regulate a range of processes including sleep, sexual functions, growth and even development. It maintains homeostasis by making sure the correct amount of hormones are released, for example, if there is an insufficient amount, then more will be released and vice versa. This system works closely with the reproductive system. The reproductive system is the body’s sex organs and helps in the reproduction of humans. It maintains its homeostasis in different ways for both men and women. For men, on cold days, the testes will retract so they are closer to the body to stay warm. On a hot day, the opposite happens. For women, the menstrual cycle is a carefully balanced system, which helps to regulate the times at which the body is most

Exercise is able to make our body change and be modified to certain intensity or a certain type of exercise. It affects the way we move, our temperature change, the health of our organs, movement of joints and the ability to push our heart to pump blood faster. Once we begin to exercise; the body has to respond to the change in intensity in order to maintain a constant internal environment (homeostasis). Acute effects of exercise affect our musculoskeletal system and the cardiovascular system. The musculoskeletal system is the grouping of the muscular and skeletal systems that work together and includes the bones, muscles, tendons and ligaments of the body. The cardiovascular system (or the circulatory system) is an organ system that

This essay will talk about how different features of the musculoskeletal system functioning in terms of movement, support and load bearing, the factors which affect tensions in developed muscle and different roles of muscle and their roles in movement. The first part to start with is to understand what musculoskeletal system is and the function of it. The basic function of musculoskeletal system is to support the human body, allow movement, support and protect organs, it also known as the loco-motor system. The system is formed by bones, cartilage, ligaments, muscles, tendons, joints and other connective tissue that supports and binds tissues and organs together. The skeletal part of the system works as storage system for calcium and phosphorus. It is essential for bones to regulate mineral balance in the bloodstream, and then the variation of minerals is high, these minerals are stored in bone; when it is low, minerals are withdrawn from the bone. The skeleton system has a critical relationship with blood production (hematopoietic) system. The hematopoietic system locates in long bones and there are two distinctions of bone marrow. The yellow marrow has fatty connective tissue, the body uses the fat in yellow marrow for energy; the red marrow is important for blood cell production. The bones also provide stability to the body; muscles keep bones in place and also play a role in movement of the bones. When movement happens, different bones are connected by joints and
