Chapter 3 ~ Biology

• organizational structure

• complex stuff at the top

• simple things at the bottom

• epithelial tissues (skin)]

• connective tissues

• muscle tissues

• nerve tissues

process which produces specialized cells

a cell that can turn into different types of cells

• embryonic

• tissues

can turn into any kind of cell

• exist with a certain kind of tissues

• can only turn into certain types of cells

a tissue being able to repair itself

researching ways to regenerate human body tissue that do not normally regenerate

takes in food, digest it and removes remaining waste

Breaks down food mechanically and chemically

• connects the mouth to the stomach

• has smooth muscle tissues which contract and relax

Moves food down to the stomach

holds food and churns it to continue the digestive process

• blood

• heart

• blood vessels

• transport nutrients and waste to and from body cells

• regulates body temp

• transport WBC to areas of bacteria

type of connective tissue with four main parts

• red blood cells

• white blood cells

• platelets

• plasma

tiny cells ~ help with blood clotting

• protein rich

• help move blood cells along

• cardiac muscle tissue

• nerve tissue

• connective tissues

take blood away from heart

take blood to the heart

• connects arteries and veins

• nutrients and oxygen are dropped off here

responsible for providing oxygen to the body and removing carbon dioxide

throat

windpipe

• air bags at the end of bronchi

• surrounded by a network of capillaries

large sheet under the lungs

Bacteria entering the lungs and spreading to the nervous system and bones

• severe Acute Respiratory syndrome

• a type of corona virus

• heart, liver, lung

• pancreas, intestine

• cornea, skin, bone

• bone marrow, tendons, blood vessels

bone and muscle that move the body

• provided structure and support

• provided anchor points for muscles

• protects internal organs

• Bones

• Ligaments

• Cartilage

connects bones together

prevents bone on bone rubbing

• skeletal muscle

• smooth muscles

• cardiac muscles

• voluntary

• are attached to the bones by tendons

• involuntary

• found in intestine

• involuntary

• found in the heart

• central nervous system (CNS)

• Peripheral nervous system (PNS)

• The brain and spinal cord

• Protected by bones

• Cushioned by cerebrospinal fluid

Made up of the nerves that carry Signals between the central nervous system and the body

• made up a special cells called neurons

• found in the brain, spinal cord, and nerves

Sends information around the body by conducting electrical signals

Specialize cells or tissues are received input from the external environment and sends signals along the Peripheral nerves to the CNS

• nervous system is responsible

• Making sense of the info we get from our environnement

Skeleton on the inside of the body (humans)

Skeleton on the outside of the body (insects)
