Lesson 9 Types of animal tissues and human organ systems A-Review A1. What are tissues made of? A2. Tissues are made of many cells A3. What are the 3 main tissues in plant? 1. Dermal 2. Ground 3. Vascular bundles B- Types of animal tissues B1. There are 4 main types of tissues B2.These tissues are found in many different animals, not just in human C- 4 types of animal tissues 1.Epithelial 2.Muscle 3.Nervous 4.Connective Tissue Locations line the body's surface (skin) and between internal organs (small intestine, lung, 1.Epithelial esophagus) Function Example type create barrier to protect body, absorb and secrete substances a. skin epithelia b. columnar epithelia in small intestine with cilia to absorb food and secrete mucous 2. Muscle specialized for voluntary and involuntary movement of various organs skeletal muscle (look striped) Cardiac muscle (unevenly striped, found only in heart) Appearance Tissue 3. Nervous Locations Function Brain made of neurons, receive and transfer signals, coordinate body actions bone, fat, 4. Connective blood support, protection, binds cells and tissues Example type Nervous tissue Bone (calcium hardened tissue) Fat (adipose tissue) blood (attack invader, transport nutrients and O) Appearance E- 11 human organ systems Organ Organ systems E1. What made up tissues? Organs? Organ systems? Body? F-General functions of some typical human organ systems F1. Immune system: F2. defend body against infections F3. Endocrine system: F4. produce hormones, act together with the nervous system to keep body in balance F5. Integumentary system: F6. skin, hair and nails that creates a barrier around the body Etc. • Full list can be studied on p 96 of your textbook G- Focus on G1. Digestive system G2. Circulatory system G3. Respiratory system H- Digestive system H1. Mechanical + chemical digestion gives proper digestion of food H2. Fate of food: H3. Start in mouth: H4. Teeth grind food (mechanical digestion) into smaller pieces H5. Enzymes in saliva chemically digest food H6.Partially digested food then pass through pharynx then esophagus then stomach H-Digestive system H7.In stomach: H8.Stomach is a muscle that further churns the food (mechanical digestion) H9.Gastric juices + HCl + enzyme pepsin secreted by stomach lining further break down food to liquid (chemical digestion) H10.Liquidy food now passed on to the duodenum where pancreas, liver and gall bladder release more enzymes H11.The food are absorbed in the small and large intestines H12.Small intestine: 6-8 m long, has finger-like projections called villi and microvilli for food absorption H13.Bacteria E.coli live in large intestine I-Circulatory system I1.Functions: transports nutrients and O2 to cells and picks up waste I2.Arteries (red) carry oxygenated blood away from the heart I3.Veins (blue) return deoxygenated blood to the heart I-Circulatory system What is O2 used for in animal cells? Hint: glucose +O2 CO2 + water + energy (Cellular respiration) Which organelle use O2 to obtain energy? Mitochondria J- Blood flow in the heart J1.Deoxygenated blood from rest of body to right atrium via superior and inferior vena cava right atrium right ventricle pulmonary artery lung where blood picks up O2 left atrium via pulmonary veins left ventricle oxygenated blood left heart via aorta to rest of the body K- Try it yourself 1. Label AD in the diagram below. 2. Which kind of blood (deoxygenated/oxygenated?) that entering: a. superior vena cava b. pulmonary vein c. pulmonary artery d. aorta 3. Where does the blood come from before entering the superior vena cava? 4. Where does the blood come from before entering the inferior vena cava? 5. Where does the blood go to after leaving the pulmonary artery? 6. The part receives blood from lung is: a. left ventricle c. left atrium b. right atrium d. right atrium Everyone Take 3 deep breath Inhale….. then, exhale….. L- Respiratory system L1.Function: brings in O2 and gets rid of CO2. L2.Air enters nose pharynx larynx trachea bronchi bronchioles (smaller branches of bronchi) alveoli (tiny sacs on the bronchioles) L3.The very thin wall of alveoli allows CO2 and O2 to be exchanged with the circulatory system M- Corpus museum in the Netherland http://www.corpus-experience.nl/index.php N-Medical imaging technology N1.The big idea: our society benefit greatly from the advancement of medical imaging technology 1.X-ray: what do you know about X-ray? N2.X-ray image is basically a shadow: radiation is shined on one side of the body, and a piece of film on the other side registers the shadow of the bones. N3.absorbed by human body N4.Huge benefits in dental and bone fracture diagnosis N5.Not without risk: can cause cancer and mutate chromosomes if exposed Dental X-ray repeatedly instrument N-Medical imaging technology 2. CT or CAT scan (CAT= computerized axial tomography): N6. X-ray beam rotates around an area of the body, generating 3-D image of the internal structures with the help of a computer CAT scan thin slice image of a N-Medical imaging technology 3.Ultrasound N7. high frequency sound waves are transmitted through the skin and reflected by the internal organs N8. These "echoes " form a picture on a screen which can be examined for any abnormalities. N9. This procedure avoids the need to expose body to harmful radiation such as x-ray N- Medical imaging technology 4. Magnetic resonance imaging (MRI) scan: N10.Use strong magnetic field and radio-waves instead of harmful X-ray MRI instrument MRI image N11.What are the differences between MRI and CT scan? N-Medical imaging technology 5. Endoscopy: N12.Technique that use a flexible tube that has a small camera on the end of it. N13.This instrument is called an endoscope which is inserted into the body via mouth, anus or small cut • Video of heart beat If time permit • REVIEW for Bio Unit test
