Lab 3 - Tissue Location & Function Guide

Vocabulary flashcards detailing tissue locations and functions for BIOL 2401 midterm preparation.

Simple Squamous Epithelium

Location: The alveoli (air sacs) of the lungs, Kidney glomeruli, Lining blood vessels, Lining body membranes. Function: Gas exchange (diffusion), Filtration of blood, Secretion of fluid.

Simple Cuboidal Epithelium

Location: The ducts of glands, Kidney tubules, The ovaries. Function: Secretion of products, Absorption of fluids.

Non-Ciliated Simple Columnar Epithelium

Location: GI Tract (stomach, small intestine, large intestine). Function: Absorption of nutrients, Secretion of enzymes/mucus.

Ciliated Simple Columnar Epithelium

Location: Bronchiole tubes, Fallopian tubes. Function: Movement of mucus & foreign objects out of throat, Movement of eggs to uterus.

Ciliated Pseudostratified Columnar Epithelium

Location: Trachea, Upper respiratory tract. Function: Secretion of mucus, Propulsion of mucus & foreign objects out of throat.

Non-keratinized Stratified Squamous Epithelium

Location: Lining of the mouth and esophagus, Lining of the vagina. Function: Protection against abrasion, water loss, & microbe invasion.

Keratinized Stratified Squamous Epithelium

Location: The epidermis (the superficial layer of the skin). Function: Protection against abrasion, water loss, UV radiation, & microbes.

Stratified Cuboidal Epithelium

Location: Sweat glands, Mammary glands. Function: Secretion & absorption.

Stratified Columnar Epithelium

Location: Salivary glands, The pharynx, The male urethra. Function: Secretion, Protection against abrasion.

Transitional Epithelium

Location: Urinary bladder, Ureters, Urethra. Function: Allows organs to stretch, Protective lining (protects bladder from urine).

Areolar Loose Connective Tissue

Location: Papillary layer of the dermis, Around organs. Function: Wraps organs, Cushions organs.

Adipose Loose Tissue

Location: Subcutaneous layer of the skin (the hypodermis), Yellow bone marrow, Around the kidneys. Function: Energy reserve, Prevents heat loss, Supports & protects organs.

Reticular Loose Connective Tissue

Location: Lymph nodes, Spleen, Bone marrow. Function: Filters & removes old blood cells or microbes, Shapes organs.

Dense Regular Connective Tissue

Location: Tendons, Ligaments. Function: Attachment, Withstands pulling.

Dense Irregular Connective Tissue

Location: Reticular layer of the dermis, Surrounding organs. Function: Provides strength in multiple directions.

Dense Elastic Connective Tissue

Location: Walls of large arteries, Trachea & bronchial tubes. Function: Returns organs to shape after stretching.

Hyaline Cartilage Connective Tissue

Location: Embryonic & fetal skeleton, At the end of long bones, Costal cartilage, Nose, trachea & larynx. Function: Provides a smooth surface for movement, Cushions and resists compression stress, Provides flexibility & support.

Fibrocartilage Connective Tissue

Location: Intervertebral discs, Pubic symphysis, Discs of the knee joint. Function: Absorbing shock, Joining structures together.

Elastic Cartilage Connective Tissue

Location: The external ear, The epiglottis. Function: Maintains the shape of structures.

Bone Connective Tissue

Location: Compact bone - on the outside of boney structures; Spongy bone - inside boney structures. Function: Supports & protects body organs, Enables movement, Stores bone marrow.

Blood Connective Tissue

Location: Inside blood vessels. Function: Transports respiratory gases, nutrients, & wastes; Enables blood clotting.

Skeletal Muscle Tissue

Location: Skeletal muscles. Function: Motion, Posture, Heat production.

Cardiac Muscle Tissue

Location: The wall of the heart. Function: Pumps blood to the rest of the body.

Smooth Muscle Tissue

Location: Walls of hollow internal organs (like the GI tract, urinary tract, blood vessels, etc.). Function: Movement of substances (like food, urine, blood, etc.).

Neurons

Location: Brain, spinal cord, & nerves. Function: Send electrical signals.

Neuroglia

Location: Brain, spinal cord, & nerves. Function: Provide structural support for neurons, Protect & nourish neurons.
