Unit 4 Section 1: Animal Form & Function ch. 20 - Mastering Biology hw questions

epithelial tissue: -structure of tissue: sheet of tightly packed cells; one or several cell layers thick. -function of tissue: lines organs and body cavities; functions in protection, absorption, and exchange. -tissue type: epidermis of skin. connective tissue: -structure of tissue: sparse population of cells in an extracellular matrix. -function of tissue: binds and supports other tissues. -tissue type: bone. muscle tissue: -structure of tissue: cells called fibers containing contractile proteins. -function of tissue: moves body parts. -tissue type: skeletal, smooth or cardiac. nervous tissue: -structure of tissue: neurons with branching extensions. -function of tissue: senses stimuli and transmits signals throughout body. -tissue type: brain and spinal cord.

Animal Tissues chart

branched

Cardiac muscle is the only muscle composed of _____ fibers.

at the ends of bones such as the femur.

Cartilage is found _____.

is the maintenance of a relatively constant internal state.

Homeostasis

Connective tissue often consists of relatively few cells embedded in an extracellular matrix.

How does connective tissue differ from the other three major tissue types?

to sense stimuli

Nervous tissue functions _____.

involuntary body activities.

Smooth muscle is responsible for

lining body surfaces subject to abrasion.

Stratified squamous epithelium is well-suited for

function

The connection between structure and ________ is a basic concept of biology.

plasma

The liquid part of human blood that consists of water, salts, and dissolved proteins is known as

loose connective tissue.

The most common type of connective tissue in the human body is

esophagus

The respiratory system includes all of the following structures except the

neuron

The structural and functional unit of nervous tissue is the

Connective Tissue A: blood -- liquid matrix; functions in transport Connective Tissue B: bone -- combination of fibers and minerals; strong support. Connective C: cartilage -- surrounds the ends of bones; strong but flexible support Connective D: adipose tissue -- fat storage; pads and inculates the body. Connective tissue E: fibrous connective tissue -- tightly packed fibers; form tendons and ligaments Connective tissue F: loose connective tissue -- loose weave of fibers; holds organs in place.

Types of Connective Tissues chart:

Epithelium A: simple squamous epithelium -- permits gas exchange across the air sacs in the lungs. Epithelium B : stratified squamous epithelium -- lines the esophagus. Epithelium C: simple columnar epithelium -- secretes enzymes and absorbs nutrients in the lining of the intestine. Epithelium D: simple cuboidal epithelium -- lines tubes in the kidney.

Types of Epithelial Tissues chart:

nervous, epithelial, connective, and muscle

What type of muscle is responsible for contractions of the digestive tract and arteries?

muscle

Which is the most abundant kind of tissue in an animal, such as a gorilla?

dermis

Which layer of the skin lacks connective tissue?

bone marrow

Which of the following is a part of the immune system?

An organ can only carry out the functions of its component tissues.

Which of the following statements about an organ is false?

It is a loose weave of fibers that functions as a packing material.
