Presentation Transcript

  1. Internally controls temperature of the body Giving birth to live young Egg laying mammals Gives birth to underdeveloped young that continues to develop in the “pouch” of the mother, where mammary glands are located Young fully develop in the uterus of the mother. Artiodactyla Mammals that have even-toed hooves.

  2. From mammary glands from which milk is produced Artiodactyla they are evened-toed ungulates Hair, mammary glands, give birth to live young, 4-chambered heart Framework for body’s tissues and protects internal organs Allows you to move your body Consists of your skin Transports nutrients, wastes, gases throughout the body Allows you to exchange gases with the environment Defense against disease Breakdown of foods into their basic nutrients for the cells to use Gets rid of liquid waste and maintains balance with the environment

  3. Contains your sense organs Involves hormones and glands which transmit chemical messages throughout the body. Makes egg and sperm Caudal Dorsal Posterior Lateral Pelvic Anterior Ventral Pectoral

  4. Umbilical Cord Nostrils Anus Mouth Tail Eyes Pinnae Pelvis Abdomen Thorax Head Trunk

  5. Obviously for sight Obviously to hear…these are the ears Obviously to smell For taste. This is the opening to the digestive and respiratory system Contains arteries and veins that connect the placenta and fetus Milk producing glands in the breasts On all mammals. For warmth and protection Exit for reproductive and excretory systems. Location in females is ventral to anus. Location in males is posterior to umbilical cord

  6. Small flap of skin protruding from the urogenital opening in a female Area that holds the testes Pelvis

  7. Area from nasal cavity to pharynx…connect the nose to the throat Taste buds Produce saliva Area where air and food passages join…the back of the throat Small flap of cartilage on the back of the tongue that covers the glottis (opening to trachea) when you swallow (so you don’t choke) Separates the nasal cavity from the mouth. Made of bone Tissue that separates the nasal cavity from the mouth. Pushed up on by the tongue when you swallow. Hole leading to the trachea (windpipe)

  8. The little piece of flesh that hangs down from the rear portion of the soft palate. It blocks food from entering the nasal passage. It aids in speech, activates the gag reflex 9. 10. Muscle in the mouth that aids in talking and manipulation of food. 11. The fold of mucous membrane that attaches the free part of the tongue to the floor of the mouth.

  9. Large flat muscle at the bottom of the rib cage…aids in breathing Makes T-cells Voice box Windpipe…how air gets to your lungs Produces growth hormones (thyroxin and calcitonin) Connects pharynx to the stomach Body cavity…contains all the internal organs of the thorax and abdomen

  10. Same thing as the Thymus gland Area posterior to the diaphragm Area anterior to the diaphragm Area containing the lungs Area surrounding the heart Membrane covering the abdominal cavity

  11. Makes bile and stores excess glucose in the form of glycogen. Filters nonnutrients from the blood. Where chemical digestion begins and mechanical digestion continues Stores blood, destroys blood cells, and makes WBC The first 25 cm of the small intestine where digestion finishes. Secretes digestive enzymes and makes insulin

  12. Stores bile Removes water from undigested material Digest food (first part), nutrients move into blood stream from here Breaks down fat No known function Stores waste until exit Where solid waste exits

  13. Muscle that pumps blood through body Carries Oxygen rich blood from the left ventricle to the body Carries Oxygen poor blood from the right ventricle to lungs Trachea divides into 2 branches which enters the lungs Where gas exchange occurs (oxygen in, carbon dioxide out) Tiny hollow air sacs that make up the lungs. Chambers of the heart that receive blood from the artia and pump blood out to either the body (left) or the lungs (right)

  14. Artery that carries nutrients and oxygen to the heart muscle cells. Chambers of the heart that receive blood from either the body (right) or the lungs (left) and pump blood to the ventricles. “Flaps” on the atria to increase the volume of the chamber Large vein that carries blood from the upper body to the right atrium Large vein that carries blood from the lower body to the right atrium Any blood vessel that carries blood Away Any blood vessel that carries blood to the heart

  15. Pulmonary Arteries Superior vena cava Right Atrium Pulmonary Veins Right Ventricle From behind

  16. Pulmonary Arteries Superior Vena Cava Right Atrium Left Atrium Rigth Ventricle Left Ventricle Coronary artery From the Front

  17. Filters water and other waste from the blood and excretes them Tube that carries fluid from the kidney to your bladder Stores Urine Tube through which urine is released Produces adrenaline and other hormones

  18. Produces sperm and hormones (testosterone) Produce eggs and hormones (estrogen and progesterone) Where fertilized egg develops Where sperm is stored Tube through which sperm is released
