In system theory‚ an open system is a system which continuously interacts with its environment or surroundings. The interaction can take the form of information‚ energy‚ or material transfers into or out of the system boundary‚ depending on the discipline which defines the concept. An open system is contrasted with the concept of an isolated system which exchanges neither energy‚ matter‚ nor information with its environment. The concept of an open system was formalized within a framework that enabled

Endocrine System A system of glands and cells that make hormones that are released directly into the blood and travel to tissues and organs all over the body. The endocrine system controls growth‚ sexual development‚ sleep‚ hunger‚ and the way the body uses food. [pic] The human endocrine system modulates several processes of the body by the function of hormones. The endocrine system secretes hormones that control how bodily functions work. Thus‚ the human endocrine system watches over

The lymphatic system is a part of the circulatory system‚ that consists of a network of vessels called lymphatic vessels. These vessels carry a clear fluid called lymph towards the heart. The lymphatic system is not a closed system. The circulatory system processes an average of 20 litres of blood per day through capillary filtration which removes plasma while leaving the blood cells. Roughly 17 litres of the filtered plasma actually get reabsorbed directly into the blood vessels‚ while the remaining

The organ systems of the human body are interdependent because one organ of the connects to another organ system. Organs are made up of tissues which that work together to keep organism‚ in this essay humans‚ alive. One function of a system always leads to another systems function. If one organ becomes ineffective/damaged‚ then that person may not function well and end up passing away. There are eleven organ systems within the human body: integumentary‚ skeletal‚ muscular‚ nervous‚ endocrine‚ circulatory/cardiovascular

Human Science – CHAPTER 1 1. Which Organ system maintains a relatively slow-acting degree of control over most bodily functions? Endocrine System (hormones act in minutes to hours‚ in contrast to nerve impulses‚ which act in fractions of a second). 2. The esophagus and the trachea run side-by-side through the thorax. In which systems are these organs found? The esophagus belongs to the digestive system‚ and the trachea belongs to the respiratory system. (The esophagus carries food to the stomach

Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

Homeostasis is defined as the adjustments a body makes to maintain an environment conducive to life. All of the organ systems in the human body must maintain a steady internal environment for the body to function properly. The factors that need to be controlled are water and salt content‚ PH balance‚ oxygen‚ sugar‚ protein‚ body temperature‚ and blood and glucose concentration. The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

through our body. The blood moves through pulmonary circulation and then continues on through systemic circulation. Pulmonary and systemic are the two circuits in the two-circuit system of higher animals with closed circulatory systems. As the heart pumps‚ blood is pushed through our body through the entire circulatory system. Oxygenated blood is pumped away from the heart to the rest of the body‚ while deoxygenated blood is pumped to the lungs where it is re-oxygenated before returning to the heart
