1BIOLOGY1Task1Part 1LEVEL OF ORGANISATION OF THE HUMAN BODYCells - These are the basic units of the form of life. It consist of all the structural and functional aspects neede for the growth and development of the organism.Tissues - Tissues are the group of cells which are of similar structure. Each of the tissue has some different function which is done by the wroking of all the cells together.Organs - Organs are formed by the association of the tissues to serve a specific function. The organs are made up of four types of tissue; epithelial tissue, which forms the inner lining, connective tissue which helps to transport the nutrients; muscle tissue that provide support to the organs and nerve tissue which sends the electric impulse to the brain and different organs. Organ system - A group of organs together make an organ system. The organs of our body are of two types - external organs and internal organs.Organism - An organism is made up of the organ system and they can carry out all the life process necessay for daily life.
2BIOLOGY1Labelling of the above pictureSystem name: respiratory systemOrganName Function 1Nasal cavityIts function is to moisturize and purify the air that is entering into thebody, before reaching the lungs2Rightbronchus The main function of the right bronchus is to carry the purified airfrom the trachea into the right lungs. 3Bronchi The bronchi contain C-shape cartilage rings that provide the passageof the air open.4Bronchioles The bronchioles uses the mucus and the cilia that are situated in theinner lining of the bronchioles for trapping the dust and keeping thelungs safe from the other impurities.5Nasopharynx Nasopharynx helps a person to breathe by remaining open all thetime. It also helps in trapping the bacteria and viruses, so that thelungs can get pure air.6Trachea Trachea mainly provides a pathway for the air to entering the lungs.Also, the epithelial cell of trachea secretes mucus which helps intrapping dust and other contaminants and prevent them from reachingthe lungs.(Gilbert-Barness, Spicer and Steffensen 2014).
3BIOLOGY17LeftbronchusThe main function of the left bronchus is to carry the purified airfrom the trachea into the left lungs.8Diaphragm The diaphragm mainly helps in respirationby contracting andrelaxing itself. When the diaphragm contracts it leads to theenlargement of the volume of the thoracic cavity and expands thelungs, which helps the air to flow into the lungs (Lumb 2016).Labelling of the above diagramSystem name: pulmonary circulatory systemOrgan Name Function1Aorta Aorta is a type of artery that carries blood from the heart.It generally ascends from the left ventricle, is curvedtowards the left and descends through the thorax andabdomen.2Pulmonary arteryThepulmonary arteryis mainly responsible for thetransport the oxygenated blood from the heart towardsthe lungs. The mainarteryis divided into two - the left
4BIOLOGY1pulmonary arteryand the rightpulmonary artery, each ofthese pulmonary artery transports the blood to therespectivelung (Lavie et al. 2015).3Pulmonary veinPulmonary veins are the type of veins thatare mainlyresponsible for carrying of the oxygenated blood to theleft atrium of heart from the lungs. This distinguishesthepulmonary veinsfrom the otherveinsof the body. 4Left ventricleDuring the systole, theventriclesused to contract andpumps the blood into the body, but during diastole, theventriclesgets relaxed and are filled with blood again(Sherwood 2015). 5Portal veinThe portal vein is a vessel that transports the blood fromspleen and the gastrointestinal tract to the liver.6Inferior vena cavaTheinferior vena cavais a type of vein that generallycarries the deoxygenated blood to the right atrium ofheart from the lower part of the body (Rizzo 2015). 7Aorta Aorta is a type of artery that carries blood from the heart.It generally ascends from the left ventricle, is curvedtowards the left and descends through the thorax andabdomen (Miller 2013).8Superior vena cavaSVC is a type of vein that carries the deoxygenated bloodfrom the upper part of the body to the heart.Labelling of the above diagram
5BIOLOGY1System name: digestive systemOrganName Function 1Mouth It helps in chewing, which breaks the food into piecesmaking it easier for the digestion (Chapman 2013).2Esophagus It performs the contraction and relaxation known asperistaltic movement, so that it can deliver the food tothe stomach.3Stomach Stomach used to secrete some strong and powerful acidthat help in the breakdown of the food so that they canbe easily digested (Hall 2015).4Small intestineIt is made up of duodenum, jejunum and ileum.Duodenum is responsible for the breakdown of thefood. Jejunum and the ileum help in absorbing thenutrients into the blood stream (Zorn 2017).5Large intestineIt absorbs the water from the undigested food andtransfer the waste of the body to the anus.6AnusIts generally eliminate the unwanted semisolid matter,known as faeces that is produced while digestion of thefood 7RectumIt receives the faeces from the colon and store thereuntil defecation (Shier, Butler and Lewis 2015).8PancreasIt secretes digestive enzyme for the breakdown of thebiochemical.10Liver It processes the nutrients that are absorbed from themall intestine.Part 3The division of labour for respiratory system is the admit to the progress of clan in clan downpatient increase its lengths; having d rest of the wordsThe division of labour for the circulatory system is transport of blood and nutrients throughoutthe body.The division of labour of the digestive system is the breaking of the food and absorbing the find.of energy
