General Biology BI 101 - Structure, Systems, Organs, Tissues, Cells

I Basic organization of Body Plans

		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 (found in the intestine), slide 8 from Lumen
			b) stratified - multiple layers (found in the gonads), slide 21 8 from Lumen
			c) cuboidal - cube shaped (secretory), slide 4 8 from Lumen
			d) columnar - column shaped (found in the intestine), slide 8 8 from Lumen
			e) squamous - flat for diffusion (found in the lungs), slides 20, 21 8 from Lumen
			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
