HCS1110 Infection & Immunity 2

Introductory · 1 credit · HRH - Health, Recreation, and Human Services

Description
Students acquire attitudes, knowledge and skills related to basic principles of immunity and the processes involved in the initial defense mechanisms to prevent infection. Students complete a study of the components of blood, pathologies related to blood, and the role of blood in the body's defence as an indicator of health and wellness. Students gain an appreciation for practising a healthy lifestyle as it pertains to the individual, family, peers and community.
Prerequisite
HCS1100: Infection & Immunity 1

Outcomes The student will:

  • 1 explain basic principles of immunity and the defence systems of the body

    • 1.1 differentiate between innate immunity (non-specific immunity) and acquired immunity (specific immunity)

    • 1.2 summarize the role of the following chemical and mechanical barriers in the body as a first line of defence in preventing the invasion of foreign substances:

      • 1.2.1 skin

      • 1.2.2 sebaceous and sweat glands

      • 1.2.3 mucous membranes and mucous secretions

      • 1.2.4 cilia

      • 1.2.5 body secretions, including tears, saliva and gastric juices

      • 1.2.6 reflexes, including coughing, sneezing, vomiting and diarrhea

      • 1.2.7 blood clotting and the inflammatory response

    • 1.3 summarize the role of symbiotic organisms as part of the body's defence system

    • 1.4 describe other non-specific lines of defence, including:

      • 1.4.1 the roles of complement and interferon

      • 1.4.2 phagocytosis (the second line of defense)

      • 1.4.3 natural killer cells

      • 1.4.4 inflammation

      • 1.4.5 fever

  • 2 explain constituents and functions of blood

    • 2.2 summarize the functions of blood, including:

      • 2.2.1 transportation of oxygen, carbon dioxide, nutrients, minerals, vitamins, hormones and waste

      • 2.2.2 regulation of pH, fluid balance and body temperature

      • 2.2.3 protection against foreign organisms and blood loss

    • 2.3 categorize the components of blood into plasma components and formed elements

    • 2.4 rate the components of blood, based on percentage of total blood volume

    • 2.5 categorize formed elements of blood, based on appearance in blood stain samples

    • 2.6 compare the characteristics and functions of the five types of leukocytes

    • 2.7 analyze the components of blood as indicators of health

  • 3 describe the mechanisms of protection provided by the blood

    • 3.1 describe the events that occur to prevent blood loss from the skin barrier after an injury, including:

      • 3.1.1 vasoconstriction

      • 3.1.2 formation of platelet plug

      • 3.1.3 initial formation of a blood clot

      • 3.1.4 final formation of a blood clot

      • 3.1.5 significance of the presence of serum at the end of the clotting process

    • 3.2 describe the role of inflammatory processes in the body as a defence mechanism

    • 3.3 differentiate between local and systemic inflammatory responses

    • 3.4 describe the events that occur to produce an inflammatory response to infection

    • 4.1 summarize the role of blood in achieving and maintaining wellness

    • 4.2 summarize the basic effects of aging on the function of blood and blood flow

    • 4.3 predict the effect of lifestyle choices on the health of blood and maintaining healthy blood flow, including choices related to cultural beliefs and practices
