Respiration. *The respiratory system consists of tubes that filter incoming air and transport it into the microscopic alveoli where gases are exchanged the entire process of exchanging gases between the atmosphere and body cells is called respiration and consists of the following: ventilation‚ gas exchange between blood and lungs‚ gas transport in the bloodstream‚ gas exchange between the blood and body cells‚ and cellular respiration *The organs of the respiratory tract can be divided into two

Information System Architectures: From Art to Science Peter C. Lockemann Fakultät für Informatik Universität Karlsruhe Postfach 6980 76128 Karlsruhe lockeman@ipd.uka.de Abstract: The presentation claims that architectural design plays a crucial role in system development as a first step in a process that turns a requirements specification into a working software and hardware system. As such‚ architectural design should follow a rigorous methodology – a science – rather than intuition –

Complete information on the mechanism of Respiratory System in Man NIRMALA AGARWAL Respiratory organs are those which are concerned with the passage of the air to and from the lungs. The latter are‚ of course‚ mot important of all. The passage is also called respiratory tract. For the sake of convenience‚ the respiratory tract can be divided into upper and lower parts. The upper part extends from the external nostrils (external openings of nose) to the vocal sac present in the neck. The lower part

Musculoskeletal: The human musculoskeletal system or the locomotor system is made from cartilage‚ bones‚ ligaments‚ tendons and muscles. This system give humans the ability to move using their muscular and skeletal systems. The musculoskeletal system is being controlled by the nervous system to provide voluntary movements. The skeletal system and the muscle system maintain to posture and produce heat for the body. Increased blood supply: As people start to exercise the muscles will start wanting

The cardiovascular system plays a vital role in circulating blood throughout the body to maintain human life. The system consists of a heart and blood vessels that help delivers blood containing oxygen and nutrients to the body organs and tissues for function. The heart is a muscular body organ located on the left side of a human chest. The heart has four chambers are known as the right atrium‚ right ventricle‚ left atrium and the left ventricle. Blood travels through the four chambers by the heart

Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth
