Are parts of the immune system (check all that apply)

They are made in your bone marrow and are part of the lymphatic system.

They do this by recognizing substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign.

The main roles of the lymphatic system are to (check all that apply)

Is a blood-filtering organ that removes microbes and destroys old or damaged red blood cells.

Is the spongy tissue found inside your bones. It produces the red blood cells our bodies need to carry oxygen, the white blood cells we use to fight infection, and the platelets we need to help our blood clot.

the mucous lining contains antibodies, and the acid in the stomach can kill most microbes

Everyone is born with______________ immunity.

immunity develops throughout our lives

immunity that is "borrowed" from another source and it lasts for a short time

Is an immune system response

The neonate and infant can receive additional maternal protection from breast milk

Most abundant type of white blood cell and the first responder to microbial infection

Prominent at the sites of allergic reactions and parasitic infections

•are chiefly responsible for initiating inflammatory responses by releasing the chemicals

slower to respond than neutrophils but are longer lasting

are responsible for the production of antibodies which target specific antigens present on pathogens

substance that is capable of stimulating an immune response, specifically activating lymphocytes, which are the body’s infection-fighting white blood cells

They send signals to the brain, so that your brain can appropriately respond to the change.

It is a complex system made up of the brain, spinal cord and the billions of neurons

Is the most complex organ in the body and uses 20 percent of the total oxygen we breathe in.

consists of the brain and spinal cord.

The retina, optic nerve, olfactory nerves, and olfactory epithelium are sometimes considered to be part of the CNS alongside the brain and spinal cord.

important for processing sensory input and assigning it emotional meaning

Visual processing region of the brain, housing the visual cortex.

Integrates sensory information including touch, spatial awareness, and navigation.

positioned at the front of the brain, contains the majority of dopamine-sensitive neurons and is involved in attention, reward, short-term memory, motivation, and planning

Consists of all the nerves branching out of the brain and spinal cord (the central nervous system, CNS).

The peripheral system does not allow the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment

The somatic system is the part of the peripheral nervous system responsible for carrying sensory and motor information to and from the central nervous system

Also called afferent neurons

Also called efferent neurons

This helps maintain normal body functions and conserve physical resources
