Cellular organelle structure and function Nucleus The Nucleus is comprised of the pore perforated nuclear membranes‚ nucleoplasm‚ chromatin and the nucleolus at the core. The nuclear envelope consists of an inner and outer membrane that forms the outer structure. Contained within the nuclear membrane are nucloplasm which is the fluid medium in which the chromatin is present‚ chromatin being the genetic material. At the core of the nucleus is the nucleolus‚ where ribosomes are synthesized. The

INTRODUCTION Social structure and social interaction are integral in evaluating a person’s identity. Identities are the sets of meanings people hold for themselves that define “what it means” to be who they are as persons‚ as role occupants and as group members (PJB article) People are generally influenced by the norms and beliefs of society. A person’s identity is formed through a combination of factors derived from social structure (macrosociology) and social interaction (microsociology). The self

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body. Energy is the strength and ability that is required in order to perform physical or mental activities. There are different forms of energy these consist of: magnetic‚ kinetic‚ heat‚ light‚ gravitational‚ chemical‚ sound‚ electrical‚ elastic and nuclear. The law‚ conservation of energy states that the total amount of energy within a system remains constant at all times‚ although energy within the system

cellular respiration from the lungs to tissues and organs. Between 2‚100 to 2‚400 gallons of air is breathed to fuel 2‚400 gallons of blood that is pumped into the heart. Respiration is controlled by the medulla oblongata‚ which deals with the autonomic function of breathing. This characteristic allows one to breathe without having to think about the process but can also be overridden and controlled in certain situations. As a result of respiration‚ carbon dioxide is produced where it is removed for oxygen

Aviation Physiology Aviation physiology is an important study for pilots‚ flight attendants‚ and other crewmembers. Its study is often brushed over during initial training. The current FAA Knowledge Examination system emphasizes multiple choice knowledge at the expense of a deeper understanding. The course will give you a chance to explore aviation physiology in a more focused manner. Physiology is the biological study of a living organism‚ in whole or in part. Aviation physiology is narrowed

What are the human organs and their function? BLADDER -A hollow muscular organ that stores urine before expelling it from the body. BONES - The bones provide 5 functions. They protect other vital organs‚ i.e. ribs protect the lungs. Support the body in an upright position. They are attached to muscles to help provide movement of the body. Bone marrow produces blood. Store salts inside provides a mineral reservoir for the body. BRAIN -The brain is the master control center of the body. It receives
