1. Body Tissues Epithelial Tissue 1.Covers all surfaces (protects). 2.Line most internal organs (absorbs, excretes). 3.Major tissue of glands (secrete a product). 4.One side exposed to the outside or an open space. 5.Tightly packed (lack blood vessels). 6.Reproduce quickly Skin Stomach

2. Body Tissues Connective Tissue 1.Cells more widely spaced than epithelial 2.Cells secrete an extracellular matrix 3.Matrix consists of fibers and ground substance (fluid to solid). 4.Tissue specific functions

3. Body Tissues Muscle Tissue 1.Moves body parts by contraction of fibers 2.Three Types of Cells 1.Skeletal Muscle (striated, voluntary) 2.Smooth (involuntary) 3.Cardiac (heart)

4. Body Tissues Nerve Tissue 1.Found in brain, spinal cord, and peripheral nerves. 2.Neuron 1.Nerve cell 2.Transmits impulses to other cells. 3.Neuroglial Cells 1.Support and bind neurons. 2.Carry on phagocytosis.

6. Body Cavities A.Dorsal Cavities 1.Cranial Cavity- encases brain 2.Spinal Cavity- surrounds spinal cord C.Thoracic Cavity- encloses heart, esophagus, lungs, trachea, bronchii D.Abdominopelvic Cavity (abdominal & pelvic)- encloses digestive, reproductive, and excretory organs E.Diaphragm- muscle that separates the thoracic and abdominal cavities

7. Digestive System 1.Mouth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancreas, small intestine, large intestine. 2.Stores and digests food 3.Converts food into forms that can pass through membranes 4.Eliminates materials not absorbed

8. Respiratory System 1.Nasal cavity, pharynx, larynx, trachea, bronchi, lungs. 2.Carries air in and out of the body 3.Exchanges oxygen and carbon dioxide between air and blood.

9. Muscular System 1.Skeletal, cardiac, & smooth muscle 2.Moves body parts 3.Produces body heat 4. Moves blood

10. Cardiovascular Systems 1.Heart, blood vessels, blood 2.Transports oxygen, carbon dioxide, nutrients, hormones, wastes.

11. Skeletal System 1.Bones, cartilage, tendons, ligaments 2.Functions a)Support b)Protective shields c)Attachments for muscles d)Produces blood cells e)Stores inorganic salts.

12. Nervous Systems 1.Brain, spinal cord, nerves, sense organs 2.Receives impulses from sensory parts 3.Interprets impulses 4.Acts on impulses by stimulating muscles or glands to respond.

13. Other Systems A. Integumentary System 1.Skin, hair, nails, sweat glands, sebaceous glands (oil) 2.Protects underlying tissue 3.Regulates body temperature 4.Houses sensory receptors 5.Synthesizes various substances.

14. 1.Lymphatic vessels, lymph nodes, thymus, spleen, white blood cells. 2.Transports lymph from tissue to blood 3.Aids in defending against disease. B. Immune System

15. C. Excretory System 1.Kidneys, ureters, bladder, urethra, skin, lungs 2.Filters waste from the blood 3.Helps maintain water and electrolyte balance

16. D. Endocrine System 1.Pituitary, thyroid, parathyroid, adrenal, pineal, thymus glands, pancreas, ovaries, testes. 2.Glands that secrete hormones which help regulate metabolism.

17. Reproductive System 1.Male system 1.Testes, seminiferous tubules, epididymis, vas deferens. 2.Produce and maintain sperm 2.Female system 1.ovaries, fallopian tubes, uterus, mammary glands. 2.Produce and maintain ova and milk

18. Regulation and Homeostasis A.Body systems work together to maintain homeostasis in the organism B.Skeletal system can donate calcium ions for muscle contraction C.Kidneys regulate electrolytes and water balance in blood

19. Regulation and Homeostasis D.Cardiovascular and respiratory systems regulate body’s pH E.Integumentary system and cardiovascular system regulate body temperature F.Integumentary, endocrine, and immune system work to protect the body from infection

20. Relative Positions 1.Lateral 2.Medial 3.Dorsal 4.Ventral 5.Anterior 6.Posterior 7.Proximal 8.Distal 9.Superior 10.Inferior
