Major Vertebrate SystemsIII. Tissues Work Togethera. Types of Tissues Current LectureClass DiscussionAnimal TissuesI. Major vertebrate systems1)Digestive______: breaks down food, absorbs nutrients, eliminates food waste2)__respiratory___: delivers oxygen to and removes carbon dioxide from all tissues3)__circulatory__: exchange of gas, waste, nutrients, stabilizes pH and temperature4)______reproductive_____: gamete production5)___urinary__: waste disposal and water balance6)___nervous_______: coordinate body activities7)______muscular_______: skeletal muscles only8)_____lymphatic____: collects and returns fluid lost from blood9)_______endocrine____: hormones10)______skeletal_____: support and protection; cartilage and bone11)______integumentary______: (skin) protects body from dehydration, injury, some pathogens, controls temp, excretion of certain wastes, receives some stimuliII. Tissues are communities of cells and intercellular substances that are interacting to carry out one or more tasks.1. Epithealial Tissue: sheets that cover the body or line the inside of organs/cavities.a. Simple squamous: thin and leaky cells. Involved in the exchange of materials.b. Simple cuboidal - single layer of cube shaped cells that function in secretion and absorptionc. Simple columnar: secretion and absorption, small intestine. These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.d. Stratified squamous: multiple layers of flat, scale-like cells that provide protection against abrasion 2. Connective Tissue - Binds and _supports_ other tissue. Consists of cells scattered throughout extracellular matrix.a. Loose connective tissue: loose fibers (matrix) sparse population of cells.b. __fibrous connective tissue: densely packed with collagen fibers, attaches muscles to bone, and forms tendons.c. _adipose tissue_: fat containing cells in sparse ground substance but surrounded by many __fibers__.d. Cartilage: cells are imprisoned in a matrix with no blood vessel supply. Offers ___support__ and ___resist compression___.e. ___bone___: cells suspended in a mineralized matrix. Offers sturdy support and movement.i. Blood: transports substances throughout the body,3. Muscle Tissue: Complete the chart below.Structure? Function?
