Presentation on theme: "A). Submaxillary Salivary Gland- B) Trachea- Conducts air from the larynx to the lungs. Lining helps catch impurities from the inhaled air. C) Thymus gland-"— Presentation transcript:

1 A). Submaxillary Salivary Gland- B) Trachea- Conducts air from the larynx to the lungs. Lining helps catch impurities from the inhaled air. C) Thymus gland- produces WBC’s D) Right Atrium-

2 E & N) Lungs- organs used for gas exchange F) Diaphragm- muscle sheet that separates the thoracic cavity from the abdominal cavity. Increases the space of the chest cavity to allow lungs to fill with air. G) Liver- produces bile, cleans and detoxifies blood, and stores glycogen in response to insulin produced by pancreas.

3 H) Small intestine- large molecules are broken down to absorbable size. Digests and absorbs nutrients. I) Larynx- voice box J) Thyroid gland- produces hormones that control metabolic rate and body growth. K) Esophagus- moves swallowed food to stomach.

4 L) Left Atrium- receives oxygen rich blood from the lungs M) Ventricle- bottom chamber of heart that pumps blood out N) See function for E. O) Stomach- chemical breakdown of foods with strong acids. P) Spleen- cleans blood, removes old RBC’s

5 Q. Large intestine- connected to small intestine. Reabsorption of water and final digestion of any vitamins and minerals. R. Cecum- junction of small and large intestine. Sac for fermentation of fibrous plant materials

6 Abdominal Organs Identify the Following : Liver Gall Bladder Stomach Pancreas Small Intestine Large Intestine Kidney

7 The Female Pelvic Cavity Identify the following: Urinary Bladder Uterus Fallopian Tube Ovary Vagina Fallopian Tube

8 The Male Pelvic Cavity Identify the following: Urinary Bladder Penis Testes Scrotum Epididymis Vas Deferens

9 Thoracic Organs Identify the Following Trachea Bronchi Lungs Diaphragm Heart 1. How is the trachea different from the esophagus? 2. How does the diaphragm contribute to the breathing process?

10 Remove a Lung Cut the lung in a frontal cross section Identify the following: Bronchi Bronchioles What are the alveoli?

11 Frog Dissection

15 EXIT OPENINGS DIGESTIVE WASTE (feces) = _________________ Shared EXCRETORY & REPRODUCTIVE EXIT = _____________________________ (Urine & eggs or Urine & sperm) ANUS UROGENITAL PORE

22 Gall Bladder Image from: http://school.discovery.com/quizzes6/muskopf/frog.html

23 PANCREAS

24 Pancreas (enlarged)

25 SPLEEN Produces and stores new RBC ’ s and processes old worn out ones

26 LARGE INTESTINE Removes water from digestive waste; concentrates feces http://www.flushing.k12.mi.us/srhigh/tippettl/biology/frog/largeintestine.html

27 Image from: http://step.sdsc.edu/projects95/Frog.Dissection/index.html KIDNEYS- Remove nitrogen waste from blood and dilute it with water to make urine; osmoregulation

28 URINARY BLADDER http://www.manheimcentral.org/~tw005690/Frog/frog.htm STORES URINE MADE BY KIDNEYS LARVAE (Tadpoles) Excrete AMMONIA like fish Adult frogs excrete UREA to conserve water

29 CLOACA DIGESTIVE EXCRETORY REPRODUCTIVE

30 LUNGS: GAS EXCHANGE http://www.flushing.k12.mi.us/srhigh/tippettl/biology/frog/index.html http:// www.stclement.pvt.k12.il.us/studentWeb/science98/GarrittPatM/alveoli.gif

31 TESTES MAKE SPERM http://step.sdsc.edu/projects95/Frog.Dissection/index.html

32 TESTES KIDNEY

33 AMPLEXUS “ firm embrace ”

34 Ways tadpoles are like fish Have a LATERAL LINE Breathe with gills Excrete nitrogen waste as AMMONIA (with gills & kidneys) Have a 2 chamber heart Have a 1 loop circulatory system

35 HEART 3 chambered heart Right atrium Left atrium Ventricle Image from: http://www.digitalfrog.com/resources/froggallery.html
