Pathophysiology - innate immune response

The response to an infection. Causes the area to redden, swell, and feel warm.

• Fever

• Mucus

• Dilation

• Inflammation

Chemical that causes the blood vessels around the infection to dilate (expand) so that more blood can flow to the infection

• Stomach acid

• Mucus

• Epithelial cells

• Histamines

Which is NOT considered FIRST line of defense?

• Helper T-Cells

• Skin

• Hair

• Mucous Membranes

What is phagocytosis?

• WBCs

• When a cells eat other cells

• When a cell collapses

• When a cell releases nutrients

The innate immune system is...

• Always working and doesn't require any special preparation

• Needs to be "primed" before it can work to its full effectiveness

• Very specific and only defends against a specific pathogen

• Not very effective at preventing intruders

What category of immune response would sneezing and mucus production fall under?

• Innate Immunity
• Acquired Immunity
• Humoral Immunity
• Cell Mediated Immunity

Cells that provide a physical barrier to resist pathogen invasion, as well as secrete protective substances to discourage the accumulation of pathogens.

• Macrophages

• White blood cells

• Epithelial cells

• Helper T Cells

What is the largest outer defense of the body?

• Stomach Acid 
• Mucous Membranes
• White Blood Cells
• Skin

Which of these statements about phagocytes is not correct

• They have many mitochondria to produce ATP for endocytosis

• They have many lysosomes containing hydrolytic enzyme

• They provide specific defence against disease-causing organism

• They are white blood cells with a lobed nuclues
