BIO 171 LAB EXAM 1 QUESTIONS
AND ANSWERS WITH COMPLETE
SOLUTIONS 100% CORRECT!!!
Neutrophils
✔✔Engulf and digest bacteria and toxins as phagocytes.
✔✔Primary defenders against bacterial infections.
Eosinophils
✔✔Help reduce allergic reactions and inflammation by releasing substances like
antihistamines.
Basophils
✔✔Support inflammation and tissue healing by releasing histamine and heparin.
Monocytes
✔✔Target and break down bacteria and viruses; they later develop into
macrophages in tissues.
Lymphocytes
✔✔Manage the immune system by directly attacking infected cells or producing
antibodies.
✔✔Key players in defending against viral infections.
WBC (White Blood Cells)
✔✔Contain nuclei and are capable of mitosis and replication.
Most abundant WBC
✔✔Neutrophils
, Most commonly seen WBC
✔✔Macrophages — due to their long lifespan and active role in microbial cleanup.
Blood plasma Cellular component - ANSWER✔✔99.9% are RBCS
<.1% are WBCS
<.1% are Platelets
Blood plasma Liquid Component - ANSWER✔✔92% water
Energy (ATP) - ANSWER✔✔We breathe for energy
ATP is our main source of energy
We gain ATP through food and breathing
One breath = 36 ATP
ACTH - ANSWER✔✔Released by adenohypohpysis
Targets adrenal gland
Signals adrenal cortex to release stress hormones such as glucocorticoids
TSH (thyroid stimulating hormone) - ANSWER✔✔Released by adenohypophysis
Targets thyroid gland
Increases metabolism
PRL (prolactin) - ANSWER✔✔Produced by Anterior lobe of Pituitary Gland.
Targets mammary glands to stimulate and sustain milk production.
