A complete review of human physiology includes the study of tissue, organs, and the various systems that together form the human body. Physiology is a key area in the study of biology, particularly if you’re taking exams.
We present all the topics here in logical order, starting from the basics and working forward to more complex systems: animal tissues, blood, metabolism and homeostasis, nutrients and vitamins, digestion, respiration, circulation, excretion, epithelial tissue and skin, the musculoskeletal system, the nervous system, the human eye, the auditory system, the endocrine system, the immune system, gametogenesis, and reproduction.
Anyone wishing to become a life science professional needs to have a strong grasp of all the information contained here. If you’ve ever wanted to understand yourself fully, inside and out, our Q&As is where you want to be!

Learn everything you need to know about this liquid that runs through our vessels. Our Q&As take you progressively through blood cells, hematopoiesis, and then cover stem cells, clotting, blood diseases, and more.
This brief sequence of Q&As takes you through the fundamentals of our metabolism and explains how your body maintains its delicate equilibrium, homeostasis, amid its inner hive of activity.
Think you know what vitamins are? How about what a nutrient actually is? This set of Q&As takes you through the fundamentals of nutrition and explains why good nutrition is key to our survival, including the primary diseases caused by vitamin deficiency.

What happens to food when we consume it? These absorbing Q&As explain the digestive process, what happens to food as it passes our lips and works its way through our bodies. Learn what your mouth, esophagus, stomach, duodenum, jejunum, ileum, caecum, colon, and everything in between, do with the food you eat.
Breathing keeps us alive and yet we’re barely aware of how —or why— we take a breath. For most of us it’s effortless. Learn the literally breathtaking reasons why the gas exchange that drives our inhalation and exhalation is so important to our survival.
The blood in our bodies is constantly in motion, traveling from one part of us to another. These easy to follow 55 Q&As reveal why our blood moves from place to place, as it filters through our circulatory pump, the heart.
Just as important as what we take in —breath and nutrition— is the body’s system to excrete what we don’t need and can’t use. These Q&As will teach you the captivating aspects of our excretory system, including our kidneys, nephrons, glomerulus, renal function, and more. Nothing here will go to waste!
Often referred to as the body’s largest organ, the skin is what keeps things all together. These Q&As are designed to teach you all about skin, its structure, and epithelial tissue in a logical way designed to show you how to keep it all together!
The musculoskeletal system symbolizes the strength of our bodies. Muscles, bones, cartilage, tendons —it’s all here and more in this enlightening series of Q&As.
Your nerves are what keep you moving, coordinating information through the brain and spine by transferring signals to get you to where you need to go. And that place you need to be is here. Our Q&As will stimulate your brain as it learns about itself!
Your eyes convert information from your brain to help you perceive what’s right in front of you. Learn about how your eyes work, and about common issues such as myopia (shortsightedness), hypermetropia and presbyopia (farsightedness) and astigmatism. You’ll see a lot more clearly after reviewing these Q&As!
Are you listening? If so, it’s because your auditory system is working. These nine straightforward Q&As are designed to reveal what the different parts of your inner and outer ear are and how they work together to catch sonic vibrations (sound waves) and convey it to your brain.
These easy to process Q&As cover everything you need to know about the endocrine system —the glands that secrete hormones, which are located throughout your body. Learn how they work and how important hormones are to our organs.
The immune system is the part of the body that keeps us safe, fighting against invaders or all sorts. These Q&As are designed to teach you easily and efficiently how our immune systems protect us. Learn here about antigens, antibodies, autoimmunity, and more.
The first phase of life —learn how sperm and egg cells are created and come together to begin life. These easy to understand Q&As will give birth to a whole new awareness of how our bodies are made.
The male and female reproductive systems are designed to provide two halves to a whole, to work together to create a human being. These well-designed Q&As explain how, start to finish, our bodies create and deliver the necessary components to procreate, from the production of sperm and egg to the naturally occurring menstrual cycle.
