Task 11.1. Level of organisation in the human body.Several people mentioned that human body is similar to the machines because they bothperform many functions in different levels. Level of complexity therefore enhances at eachfunctional level. Such level of human body includes -Cells :- it is described as a basic element of human body parts. These are the basic functional andstructural units which carries out life processes in a specialized manner to enhance the level ofsurvival (Hossain, Norulaini, Banana and Omar, 2016). Specific roles are played by every cells,for example- electrical messages are carried out with the help of nerve cells whereas energy isgenerated with the help of muscle cells because it consists of mitochondria. Tissues : - tissues are characterized after cells under organisational structure of human body.They both perform similar functions. Consisting of four types- muscle, epithelial, connectivetissues and nervous. Connective tissues forms out body structure, muscle tissues possessuniqueness in contracting and resizing at different levels, the inner and outer lining of bodysurfaces are done by epithelial tissues which protects organs and secretes substances of humanbody. Lastly, nervous tissues focus in carrying electrical messages. Organs and organ system :- this comes after tissues and this further consists of two or more typesof tissues which comes together to perform effective jobs. Such organs consist of- kidneys,lungs, skins, brain and heart. Group of organs comes together to carry out complex tasks areregarded as organ system (Burgess-Limerick and Lynas, 2016). Organ system are furthercomprised of digestive, endocrine, cardiovascular, lymphatic, muscular, integumentary,respiratory, nervous, reproductive, respiratory, urinary, immune and skeletal. 1.2. Explain structure of an organ which performs several effective functions.Structure of the human body such as subatomic particles, molecules, organ system, cells,tissues, biosphere and organisms are considered under different levels that enormously increasein complexity. Scientists has considered blocks of matter in the simplest manner such as atoms,molecules and subatomic particles to generate effective understanding of chemical level oforganizational structure (Sommer and Bäckhed, 2016). Elements are composed of puresubstances alike- carbon, nitrogen, calcium etc. further the smallest unit of such substances isregarded as atoms. On the other hand if two or more atoms are bought together than it forms a1
molecule and are considered as chemical building blocks. Similarly, by combining sub atomicarticles including- proton, neutron, electron etc. generates atoms. Independent unit which functions under living organisms are termed as cells. Organellesare considered as water based cellular which consists of several tiny functioning units. Cellsbasically performs effective functions that are a necessity under human life (Drucker, 2016). On the other hand, specific functions of human body are undertaken with group of sellsare called tissues. While, structure of human body with distinctive functions among two or moretissues are termed as organ. Physiological functions are performed by each and every organs.The group of several distinctive organs are recognized as organ system. Organ system includes-integumantary system, skeletal system, muscular system, nervous system, endocrine system,cardiovascular system, lymphatic system, respiratory system, digestive system, urinary system,male and female reproductive system. The highest level of organization is considered as organism level. It consists of a cellularstructure which performs physiologic functions independently which is a basic necessity underhuman life. Task 22.1 Role of key components of balanced diet.There are seven components of balanced diet which significantly performs effective rolesin day to day life of human beings. It includes-Vitamins : - it comprises essential vitamins such as- vitamin A, B, C and D. by taking equalamount of fruits and vegetables these all ideal vitamins can be obtained. Unsaturated fats : - many of humans avoids intake of fats by assuming that it would lead ingenerating weight gain. However, there are many health fats sources like dairy products, meatand fish which contributes in generating vitamins and even regulates body temperature (Doeven,Brink, Frencken and Lemmink, 2017). Carbohydrates : - it generates excellent energy under human body and should intake about 60%of human diet. Pasta, potatoes, wheat and rice are some effective carbs-rich food items.Minerals :- these are the main component which enhances energy and promote growth in thehuman body. For example- calcium enhances development of bone and teeth, iron helps ingaining energy etc. iodine, sodium, potassium are regarded as the most effective unit of minerals.2
