The increase in leukocyte number in the blood associated with infection  is called: margination leukocytosis neutralization diapedesis

Which cytokine stimulates the liver to produce fibrinogen and protein C? Interleukin-1 Interleukin-6 Thrombopoietin Tumor necrosis factor

For each of the following scenarios: 1. State the division of the ANS that is represented 2. Draw in the specific neurotransmitter released in the synapse between the pre- and post-ganglionic neurons 3. Draw in the specific neurotransmitter released in the synapse with the target tissue (effector) 4. Draw in the type of receptor on the post-ganglionic neuron 5. Draw in the type of receptor on the target tissue (effector) 6. State the effect this set of neurons has on the target tissue (effector) Example: Sympathetic 0--< Ach o--- ANS Division 0---< 0 0---< 0- 0---< 0---< 0- Nicotinic receptor 0---< 0----< 0----< 0----< NE Alpha-1 receptor Dilator pupillae muscles of iris Target/Effector Heart muscle Heart muscle Smooth muscles of bronchioles Smooth muscles of bronchioles Eccrine sweat glands Apocrine sweat glands Stomach glands that secrete acid Smooth muscle of most blood vessels Dilates pupils Target Effect 0---< 0- 0- 0---< 0- 0---< 0- 0- 0----< 0----< 0----< 0----< 0----< Adipose…

Briefly mention types of Leukocytes and the role each one plays in defence against pathogens.

The process of macrophages bringing microbes inside the cell to destroy them is called:     diapedesis     chemotaxis     leukocytosis     phagocytosis

Release of phagocytes is considered which line of defense?     second     third     first

A neutrophil detects a pathogen, which step would most likely happen next?     Increase in intracellular levels of Arp2/3     Decrease in intracellular levels of Arp2/3     Neutrophils do not respond to pathogens.     Decreases in capZ

A patient is brought to the hospital with major trauma during a mass casualty event.  Because her injuries are critical and staff is limited, there is no time to obtain a blood type.  What type of blood will be given to the patient and why?

Match the formed elements with their functions: Erythrocytes thrombocytes granulocytes neutrophils basophil natural killer cells Choices  nonspecific innate defense mechanisms carry oxygen to tissues  seek out and destroy bacteria via phagocytosis  recognize and destroy abnormal host cells basophil releases histimine; function in allergic reactions and inflammation responses  formation of blood clots and tissue repair
