I Basic organization of Body Plans Hierarchy Systems composed of Organs Organs composed of Tissues Tissues composed of Cells II Tissues - major components of systems and organs A) Special types of tissues 1)Epithelial - linings and coverings a) simple - single layer (intestine) b) stratified - multiple layers (gonads) c) cuboidal - cube shaped ( secretory) d) columnar - column shaped (intestine) e) squamous - flat for diffusion (lungs) f) Summary from Campbell 2) Connective tissue - very diverse a) loose - holds organs in place b) adipose - storage and insulation c) fibrous - tendons and ligaments d) cartilage and bone cartilage as connective tissue 1 cartilage as connective tissue 2 location of bone - femur bone as connective tissue e) blood blood as connective tissue f) muscle - movement components of muscle smooth muscle skeletal muscle cardiac muscle Summary from Campbell g) nervous nervous tissue example h) summary from Campbell III Size and shape A) SA/V relationship is designed to maximize diffusion and minimize energy expenditure IV Overview of the systems A) Integumentary - outer covering B) Muscular - movement C) Skeletal - support, movement, protection D) Circulatory - circulatory materials and immunity E) Lymphatic - circulation and immunity F) Respiratory - gas exchange G) Digestive - digestion and absorption H) Urinary/Excretory - discharge nitrogenous waste I) Endocrine - messages and control J) Nervous - control K) Reproductive - reproduction V Homeostasis A) maintenance of stable internal environment, requires integration of all systems B) Example of body temperature IV Integumentary System - outer covering of the body A) Current Issues - Acne 1) inflammation of the skin due to excess production of sebum (oil from sebaceous gland) 2) causes of acne - hormones (androgens), increased sebum production, bacteria enlarged glands 3) AcneNet for more information B) Integument 1) Epidermis - thin outer layer with skin pigments 2) Dermis - thicker inner layer, contains vessels, hair or feather follicles, nerves, sweat glands, sebaceous glands
