What are the major components of each of the body systems?
: nerve cells that project information throughout the body. This is composed of the CNS and the PNS. The PNS breaks down further into automatic movements (autnomic) and voluntary movements (somatic). The autonomic system also has the sympathetic and parasympathetic systems which eith excite or relax the body's internal and external modes.
work in par with the nervous system. Glands release hormones that react with various targets in the body. This system is longer lasting and slower than the NS. There are lipid soluble and water soluble hormones.
The Immune system:
protects the body from invaders. antigens turn bad and become pathogens, which are the sicknesses and diseases. This system has THREE levels of defense; external barries, non specific immunity and specific immunity
The circulatory system:
transferring blood through the body. This system consists of WBC, haemoglobin, and platelets. There are also three pathways in which the blood is taken: the Pulmonary (to the lungs), the sytemic (to the body and back to the heart to be transported to the lungs) and the cardiac ( oxygen rich blood just for the heart)
- The respitory system: the exchange of oxygen. there is internal and external systems. internal is all about metabolization and external is all about breathing. there are many different airways:
- pharynx (throat)
- larynx (voice box)
- nasal cavity
: it deals with the motility, secretion, digestion and absorption of nutrients and food.
The endocrine system and STRESS
- the hypothalamus interacts with the pituitary gland
- the pituitary gland releases ACTH
- ACTH reacts with the adrenal gland
- releases epinephrine, norepinephrine and cortisol
What are the three levels of immunity of the immune system?
skin and mucous membranes
- 2.Non specific immunity: responds to ANY antigen.
- lymphocytes-NK cells
- inflammation-cells migrate to infected area
- 3.Specific immunity: remebering specific antigens and responding quicker to the exposure the second time
- Memory B cells-produce the antibodies
- Helper T cells- help the B cells
- Surpressor T cells-decrease the production of antibodies

What is Appraisal?
assessing an event to decide whether or not it is stressful
Primary appraisal: Irrelevant, benign positive, stressful
If stressful: harm/loss, threat, challenge
secondary appraisal: assessing your resources to see their ability to cope with the possible stressful event
reappraisal:existing appraisals are changed or modified with new information
How do you measure immunocompetence?
Blood cell count:
look at NK cells, Bcells, Tcells...if TOO MANY cytokines ( inflammtion) are coutned, THIS IS BAD!
- Functional States: In vitro- add mitogen to blood sample or expose NK cells to tumors and see their lysis abilities
- In vivo- inject antigen into body and see how many antibodies are produced.
BUT!!! for the Herpes virus, the more the better for Ab because they are always around to KEEP IT IN CHECK...
in any other circumstance, too many Ab is BAD!
How does stress effect the immune system?
Acute stress lowers specific immunity and increases NK cells
Short term stress increases specific immunity
longterm stress lowers specific immunity and increases inflammation!
- most common effect of stress
- more vulnerable to get sick if you are highly stressed
negative interactions, competing for attention and all affected cytokine levels ( increased inflammation)
longterm stress from a traumatic event
study: vetrans with PTSD had higher levels of sickness
TO SAY THAT STRESS IS CAUSING THE ILLNESS, YOU HAVE TO MANIPULATE STRESS!!!
What are the kinds of coping? (2)

- this is best used when you CANT FIX THE PROBLEM!
- reasurrance, avoidance, distractions
- Problem focused: coming up with a solution to the problem/stressor
