HUMAN PHYSIOLOGY

About the course

Dear Learners, Human Physiology (BBCCT-115) is one of the Fourth-semester courses of the B.Sc. (Hons.) Biochemistry programme (BSCBCH). The theory course of Human Physiology (BBCCT-115) has a 4 credit weightage and its laboratory course (BBCCL-116) is of 2 credits. Human Physiology deals with the study of normal function and vital processes of the human body. Physiology is the branch of biology that aims to understand how living things work. It describes the fundamental mechanism behind the body's functions from how cell organs and organs system work together as a unit at the organism level. While reading this course, your brain, lungs, heart and other body organs are functioning actively and continuously. Have you ever thought, how these body organs function?. Human physiology tells us how our body works in a healthy and disease state. Therefore, this course will introduce you about the structural components of human body from cells to the organ system. You will learn more about structure and function of body organ systems which include the cardiovascular system (Heart and blood vessels), respiration (Lungs), excretory system (Kidney), gastrointestinal system (digestive organs stomach, intestine, etc.), liver, reproductive system, musculoskeletal system, and the nervous system. You will also gain basic physiological knowledge about the body organs what they do within the body and how they work. The goal of this course is to provide the basic concepts and elementary principles for better understanding of the human body.

Block 1 is about the “Homeostasis and Cardiac Physiology”.

Its first unit deals with the organisation of body system, body fluids compartment and the homeostasis.

It further speaks in detail about components of blood, blood coagulation, mechanism of blood clotting and blood disorders in unit 2.

The structure and function of heart and cardiac cycle, blood pressure and its regulation are also discussed in the unit 3.

The unit ends with the cardiovascular system and cardiac disorders (unit 4).

Block 2 deals with the Respiratory and Renal Physiology wherein you will learn about structure, function and diseases of Lung and kidney.

The mechanism of respiration, transport of gases and respiratory diseases are also described (Units 5-6).

The mechanism of urine formation, renal regulation and kidney diseases are also explained (Units 7-8).

Block 3 talks about the Gastrointestinal system and Reproductive Physiology.

It describes the structure and function of digestive organs and the role of stomach and intestine in food digestion and absorption (Unit 9).

You will also learn and understand the structure and function of liver and its role in metabolism (Unit 10).

This block also describes the human reproductive system which includes structure of testes and ovary, spermatogenesis and Oogenesis. It gives you detail understanding about implementation, fertilisation and placenta (Unit 11).

Block 4 is on Musculoskeletal and Nervous Physiology which includes the structure and functions of bones and muscles cells and nervous system. The formation of bones and the mechanism of muscular contraction are discussed in unit 12.

This block also discusses the components of human nervous system and the structure and function of nerve cells and their role in synaptic transmission in unit 13.

The senseroy receptors, somatic sensation and the role of brain in sleep, learning and memory and the brain disorders are described in unit 14.
