Physiology in Zoology Quiz

Physiology in Zoology

Definition

• Physiology studies the functions and mechanisms in a living organism, focusing on how biological processes work.

Key Concepts

1. Systems Overview

   • Nervous System: Coordinates body functions through nerve signals; includes central nervous system (CNS) and peripheral nervous system (PNS).
   • Circulatory System: Transports nutrients, gases, hormones, and waste products; involves heart, blood vessels, and blood.
   • Respiratory System: Facilitates gas exchange; includes lungs in mammals or gills in fish.
   • Digestive System: Breaks down food into nutrients; involves organs like the stomach, intestines, and liver.
   • Endocrine System: Regulates body functions through hormones; includes glands such as the pituitary and thyroid.

2. Homeostasis

   • Maintenance of stable internal conditions despite external changes.
   • Involves processes such as temperature regulation, pH balance, and osmoregulation.

3. Metabolism

   • Total of all chemical reactions in a body, including catabolism (breaking down molecules for energy) and anabolism (synthesizing compounds).
   • Essential for growth, reproduction, and repair.

4. Reproductive Physiology

   • Study of reproductive systems and processes in animals.
   • Includes mechanisms of fertilization, development, and parental care across species.

5. Adaptations

   • Physiological changes that enhance survival in specific environments.
   • Examples include camouflaging, thermal regulation, and metabolic adaptations during fasting.

6. Physiological Processes

   • Circulation: Mechanisms of blood flow; adaptations to support varying activity levels among species.
   • Respiration: Methods of oxygen intake and carbon dioxide expulsion; varies between aquatic and terrestrial species.
   • Excretion: Removal of waste products; processes include filtration, secretion, and reabsorption.

7. Neurophysiology

   • Focuses on nerve cells and their signaling; studies reflexes, sensory perception, and brain function.
   • Understanding of synaptic transmission and neurotransmitter action.

8. Comparative Physiology

   • Compares physiological traits across species to understand evolutionary adaptations.
   • Examines how different environments influence physiological traits.

Applications

• Understanding animal physiology aids in conservation, veterinary medicine, and improving animal husbandry practices.
• Advances in comparative physiology impact biotechnology and medicine.

Study Methods

• Conduct laboratory experiments to observe physiological responses.
• Utilize field studies to assess physiological adaptations in natural settings.

Conclusion

Physiology is a crucial subfield in zoology that helps explain how animal bodies function, adapt, and maintain life through intricate processes and systems.
