HUMAN PHYSIOLOGY

Course Code: MBCE-013

Assignment Code: MBCE-013/TMA/2025

Maximum Marks: 100

Answer all the questions given below.

1. Define thermoregulation and explain its importance in maintaining homeostasis in the human body.

2. Write short notes on the following:

i. Differentiate between the four primary types of tissues: epithelial, connective, muscle, and nervous tissue. Provide examples of each.

ii. Discuss the structure and function of epithelial tissues. How are they classified based on layers and cell shape?

3. What are the main components of a homeostatic control system? Discuss how feedback mechanisms contribute to maintaining homeostasis.

4. Describe the physiological responses involved in thermoregulation during exposure to cold and heat stress.

5.i. Explain the process of gas exchange in the respiratory system. How do oxygen and carbon dioxide diffuse between the lungs and blood?

ii. Discuss the impact of the Bohr effect on oxygen transport in the blood. How does it facilitate oxygen delivery to tissues during exercise?

6. Explain the structure and function of the heart as a blood pump. Include a description of its chambers, valves, and layers.

7. Discuss the components and significance of the cardiac conduction system, including the roles of the SA node, AV node, and Purkinje fibers.

8. Discuss the process of hematopoiesis and the regulation of blood volume. How is erythropoiesis controlled by erythropoietin?

9. Describe the ABO and Rh blood group systems.

10. Explain the mechanism of blood clotting, detailing the intrinsic, extrinsic, and common pathways, and the role of thrombin and fibrin.

Note: Draw the figures/flowcharts/tables wherever required.
