carry full investigation and analysis on the Skeletal system‚using my class notes‚researching on the internet and reading books. The Skeletal system is the system of bones‚ associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human skeletal system. Joints are very important because they make the hard

Excretory system DEFINITION The excretory system is a passive biological system that removes excess‚ unnecessary materials from an organism‚ so as to help maintain homeostasis within the organism and prevent damage to the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and gaseous wastes‚ as urine and as a component of sweat and exhalation. As most healthy functioning organs produce metabolic and other wastes‚ the entire organism depends on

The Endocrine System System Although we rarely think about them‚ the glands of the endocrine system and the hormones they release influence almost every cell‚ organ‚ and function of our bodies. The endocrine system is instrumental in regulating mood‚ growth and development‚ tissue function‚ and metabolism‚ as well as sexual function and reproductive processes. In general‚ the endocrine system is in charge of body processes that happen slowly‚ such as cell growth. Faster processes like breathing

NERVOUS SYSTEM The human body’s activities are regulated by two systems – the nervous system and the endocrine system. Although both systems control body functions‚ their methods differ. The nervous system is the body’s information gatherer‚ storage center and control system. Its primary function is to collect information about the external conditions in relation to the body’s external state‚ to analyze this information‚ and to initiate appropriate responses to satisfy certain needs; the most

There is around 4% of every breathe that the body intakes the oxygen is absorbed into the blood. There are two body systems that are involved in the getting the oxygen and energy into the blood‚ respiratory and digestive system. The role of a respiratory system goes through many steps before the oxygen gets into the blood. The first step is when the air enters the nose and mouth and travels down into through the pharynx‚ larynx and towards the trachea. After it pasts the trachea‚ the air will travel

Tiffany Goh Biology SAC 3 “The Transport systems play an essential role in the survival of flowering plants and mammals” It is imperative that the organism’s cells have an ideal supply of the necessary materials to ensure its survival. At the same time‚ waste material must be removed to make room for the new material coming in and to avoid infection. Necessary substances and waste material merely move in and out of unicellular organisms by diffusion‚ osmosis or active transport due to direct

Pig and Human Anatomy In today’s standard anatomy classes- among other science classes- pigs are the most commonly dissected mammal because they have the most similar anatomy to a human. They have the same organs and many of the same muscles pertaining to similar human functions. When dissecting pigs it is important to remember the basic directional points. For example‚ median means to the middle‚ lateral means to the sides‚ dorsal is the belly-side‚ etc. It is also important to have lab safety
