what type of tissue lines the bladder

transitional

what are the types of loose connective tissue

• areolar (most widely distributed type → covers organs and tissues)

• adipose (body fat → insulates and protects)

• reticular (forms internal framework of organs)

what is elastic cartilage

cartilage found in the external ear and the epiglottis that prevents fluids from being swallowed into the trachea

what is adipose tissue

fatty tissue that stores long term energy and cushions vital organs

what is bone

ossified tissue that supports the body and protects vital organs

what are the types of dense connective tissue

1. irregular → collagen fibers are going different directions

2. regular → collagen fibers are going the same direction

3. elastic

what is cartilage

less hard and more flexible connective tissue than bone.

• three types:

  • 1. hyaline (most widespread)

  • 2. Elastic (external ear)

  • 3. Fibrocartilage (areas of high pressure → miniscus)

types of connective tissue

1. loose connective

2. dense connective

3. bone

4. cartilage

5. blood

dense connective tissue/characteristics

a type of connective tissue that keeps everything togherter. Makes up tendons (muscle to bone) and ligaments (bone to bone)

things that muscle tissue does/characteristics

• moves food through dicestive tract

• contract

• allows you to run

• pumps blood

things epithelial tissue does/characteristics

• covers bodys external surfaces + lines body cavitities

• cells may protect, absorb, secrete, or form a filtering membrane Cells

• classified by shape and layers of cells

things connective tissue does/characteristics

• most abundant tissue type, a matrix

• supports and connects either by structure or action

• packages and anchors organs

things nervous tissue does/characteristics

• transmits chemicla messages and electricla impusles throughout the body

• part of larger sytstem that includes the spinal chord and brain

function of connective tissue

provides protection/supports body and binds body tissues together

function of muscle tissue

contraction, shortening, and produces movement

function of epithelial tissue

covers body, linings, and glandular tissue. Job is protection, absorption, filtration, secretion.
