HUBS 191: An Overview of Anatomy and Physiology

HUBS 191 is a course focused on providing students with a comprehensive understanding of human biology, particularly through the interplay of anatomy and physiology. In this module, we will explore the structure and function of various organs, tissues, cells, and systems within the human body. Here's what you can expect from your study of HUBS 191:

Anatomy

Anatomy refers to the study of the structure of the body, both macroscopically (visible structures) and microscopically (cellular components). This includes studying the organization of organs into organ systems, such as the respiratory system, nervous system, digestive system, endocrine system, urinary system, reproductive system, cardiovascular system, lymphatic system, muscular system, skeletal system, integumentary system, and the immune system. These systems work together to maintain homeostasis, ensuring our bodies remain stable despite changes in external conditions.

At the cellular level, we learn about the structure of different types of cells—such as epithelial, muscle, nerve, connective tissue, blood vessels, blood cells, and glandular cells—and how these cells interact to form larger structures like bones, muscles, tendons, ligaments, nerves, blood vessels, and skin.

Physiology

Physiology involves understanding the functions of individual organs and systems, as well as their interactions. For instance, the heart pumps fluid containing oxygen to all parts of the body; this ensures that each part receives enough nutrients and energy to survive, grow, repair itself, and maintain its specialized functions. We also examine how hormones regulate growth, reproduction, mood, sleep, hunger, thirst, etc., using feedback mechanisms involving chemical signals released by one type of cell which cause another group of cells to respond appropriately.

Furthermore, we delve into topics like metabolism—the process by which food supplies our body with fuel—as well as the process of excretion, where waste products are removed from the body to prevent them from damaging it. Other areas addressed in physiology include vision, hearing, taste, olfaction, equilibrium, temperature regulation, circulation, nutrition, respiration, surface area, mass, renal and liver function, gastric juices, bile salts, elimination, assimilation, secretions, excretions, transpiration, osmosis, diffusion, solubility, absorbability, membranes, permeabilities, movements, contractions, and reflexes.

By studying HUBS 191, you will develop a comprehensive understanding of how various parts of the human body work together in harmony to keep us healthy, active, and alive.
