Exam 2 Intro to Biology

What is Histology?

A branch of biology that studies biological tissues

Benefits of studying histology

able to detect tissue that has been affected by pathogen, disease, or damage

relationship between cells, tissues, and organ

they function together to form organ systems to sustain the whole organism

what are the four types of tissue?

muscle, circadian, skeleton, smooth

How are epithelial tissues are classified

based on cell shape and number of layers, including simple and stratified forms.

Where would typical epithelial tissues be found in the body

outer surfaces of the body and lining internal cavities, organs, and tracts

unique feature of connective tissues? What are some examples of connective tissues?

defined by its extensive extracellular matrix- examples are: bone, blood cartilage and fat tissue

A large intestine is a

organ

a neuron is a

cell

blood is an example of

tissue

functions of epithelial tissues

metabolic functions: protection, absorption, filtration, secretion

Cartilage tissue

located in joint surfaces, outer ear, nose

Adipose tissue

located under skin, around kidneys, and eyes

blood tissues

located within blood vessels

bone tissue

located through the entire skeleton

the benefit of cardiac muscle being structurally branched?

Allows electrical signals to travel in all directions so the whole heart can squeeze together at the exact same time

What is a mircroorgansim

an organism that is too small to be seen without an aide of a microscope

Bacteria and Fungi domain grouping

Bacteria is prokaryotic and Fungi is eukaryotic

What domain do yeast belong to?

Eukarya

The equation for fermenation in yeast

c6h12o6→2co2+2c2h5oh

What is the substrate of yeast fermenation?

Sugar

the products of fermenation

Ethanol and carbon dioxide

In lichen, what provides structure and protection

Fungus

in lichen what provides nutrients

green alga

three forms of lichen

Crustise,Foliose, and Fruiticose
