Human Body May 30‚ 2010 The Cardiovascular and Muscular Systems Organ system is a group of organs that work together to perform a certain task. Humans have a variety of systems due to the complexity of the species’ organism. The human body consists of biological systems‚ that consist of organs‚ that consist of tissues‚ that consist of cells and connective tissue. Although an organ has a specific function‚ organs also function as part of a group. The organ system is the organizational unit

Effects of Smoking on Respiratory System Effects of Smoking on Respiratory System Every day‚ millions of people light up a cigarette and smoke. Some have just started smoking‚ while others have smoked their whole lives. Most likely‚ once you start smoking‚ you won’t be able to stop. It will be nearly impossible and if possible‚ it will not be easy. When people start smoking‚ they don’t really think about the harm that they are doing to themselves with every cigarette. Some don’t know how bad

The musculoskeletal system gives us our form and allows us to move. The skeleton holds everything in the body in place and protects it while the muscles let us move. As is suggested by its name‚ the musculoskeletal system is made up of both the muscular system and the skeletal system and is primarily responsible for the structure‚ support and movement of the body. Without this system‚ the body would not have any form and would not even be able to hold itself up‚ let alone move. The skeletal system

Michael M. Smith Changes in the human musculoskeletal system Instructor: Kimberly Whiting February 15‚ 2013 Michael M. Smith February 15‚ 2013 The musculoskeletal system is one of the most important systems in the human body. It provides a frame for the body not only in order to protect and support our vital internal organs‚ but also helps to provide movement for the body through our bones‚ joints‚ and muscles. This complex system goes through great changes as we grow

Respiratory system: Minute ventilation is the quantity of oxygen which is taken in by your lungs per minute. When we exercise there is a higher oxygen intake per minute due to a higher breathing rate‚ we will also need more oxygenated blood cells to go round to the muscles in use to help try and prevent muscular injuries. The reason why when minute ventilation increases is positive to an athlete is because there is a higher intake of oxygen and nutrients needed. This will mean that the athlete

As the subject enters the exercise phase there is an increased metabolic demand due to the heightened workload of the skeletal muscles and organ systems. In order to accommodate this rise in oxygen demand there must be an increase in the subject’s minute ventilation. The rise in minute volume‚ with exercise‚ could be accomplished by increasing the volume of each breath‚ the tidal volume‚ increasing the respiratory rate or by some combination of the two. In the subject’s case it was a combination

The cardiovascular system‚ also known as the circulatory system‚ is composed of the heart‚ blood vessels‚ and blood. The term cardiovascular refers to the heart (cardio-) and blood vessels (vascular). The term circulatory refers to the circulation of the blood. The heart is a muscular pump and its regular contractions send blood into tough‚ elastic tubes called arteries‚ which branch into smaller vessels and convey oxygen-rich blood through the body. The arteries eventually divide into tiny capillaries
