The liquid component of blood that transports nutrients, proteins, ions, hormones, and  cell waste is:

plasma

100

The two upper chambers that collect blood returning to the heart are:

atria

100

The neuron component that conducts an electrical charge to the synaptic terminal is the:

axon

100

The type of muscle that allows for movement of the body and are connected to bones by tendons are:

skeletal muscles

200

Too much of a stimulus causing a reduction/dampening of stimulus is:

negative feedback

200

The blood component that contains hemoglobin, the protein that binds oxygen are the:

red blood cells

200

When the left ventricle contracts, it sends oxygenated blood into the: aorta

aorta

200

Chemicals that can affect behavior and are released and re-absorbed at the neuron synapse are:

neurotransmitters

200

The two thick and think filament proteins that comprise the myofibrils of muscle fibers are: actin and myosin

actin and myosin

300

Animals that use metabolism to maintain body temperature are:

 endotherms

300

The thick walled, highly elastic blood vessels that carry blood away from the heart are:

arteries

300

If blood moves backward through heart valves, the abnormal sound is called a:  

heart murmur

300

The ability of the brain to alter physiology through use by increasing the complexity of connections is:

neural plasticity

300

In addition to anchoring muscles to allow movement and protection of organs, bone tissue provides:

Widening of blood vessels near the skin surface to increase blood flow to cool the body is:

vasodilation

400

The thin-walled blood vessels that allow substances to diffuse into and out of tissues are:

capillaries

The eye tissue where light energy is converted to an action potential and sends a signal to the optic nerve is the:

retina

400

The fibrous connecting tissue that covers the outer bone surface and connects bones, sometimes torn through exertion are:

ligaments
