About PIO 211 at Benson Idahosa University
This course material covers the physiology of excitable tissues, renal physiology, and blood and body fluids, tailored for Benson Idahosa University (BIU) students. Topics include heat production and loss mechanisms, hypothalamic thermoregulation, biological rhythms, serum vs. plasma composition, haemopoiesis, fibrinolysis, platelet functions, the coagulation cascade, the reticuloendothelial system, blood transfusion risks, white blood cells, plasma proteins, homeostasis, and control systems. It is designed for pre-clinical medical and health sciences students preparing for BIU exams.
Practicing past questions by topic helps you master the specific terminology and mechanisms tested in BIU physiology exams. By focusing on each topic individually, you can identify weak areas, reinforce key concepts like clotting pathways and thermoregulatory feedback, and build the recall speed needed for high-stakes assessments. This targeted approach ensures you cover the full syllabus efficiently and reduces last-minute cramming.

What is the difference between serum and plasma?
Plasma is the liquid component of blood after centrifugation with an anticoagulant, containing fibrinogen and clotting factors. Serum is the liquid remaining after blood clots, so it lacks fibrinogen and most clotting factors.
Where does haemopoiesis occur in adults?
In adults, haemopoiesis occurs primarily in the red bone marrow of the axial skeleton (vertebrae, ribs, sternum, skull) and proximal ends of long bones. In fetal life, it occurs in the yolk sac, liver, spleen, and bone marrow sequentially.
What are the main functions of platelets in hemostasis?
Platelets contribute to hemostasis by adhering to exposed collagen at injury sites, aggregating to form a platelet plug, releasing vasoconstrictors (e.g., thromboxane A2), and providing a phospholipid surface for coagulation factor activation.
How does the hypothalamus regulate body temperature?
The hypothalamus acts as the body's thermostat. The anterior hypothalamus promotes heat loss via vasodilation and sweating, while the posterior hypothalamus promotes heat production and conservation via shivering, vasoconstriction, and increased metabolic rate.
