This book provides two thousand multiple choice questions on human anatomy and physiology, separated into 40 categories. Each category has an introduction to set the scene for the questions to come. However not all possible information is provided within these Introductions, so an Anatomy and Physiology textbook is an indispensable aid to understanding the answers. The questions have been used in examinations for undergraduate introductory courses and as such reflect the focus of these particular courses and are pitched at the level to challenge students that are beginning their training in anatomy and physiology. The questions and answer combinations are to be used both by teachers, to select questions for their next examinations, and by students, when studying for an upcoming test.
Anatomy describes the structure and location of the different components of an organism to provide a framework for understanding. Human anatomy studies the way that every part of a human, from molecules to bones, interacts to form a functional whole. There are two major types of anatomy. Gross macroscopic anatomy is the study of anatomical structures that can be seen by the naked eye, such as the external and internal bodily organs. Microscopic anatomy is the study of tiny anatomical structures such as tissues and cells.
Hair is one of the characteristic features of mammals and has various functions such as protection against external factors; producing sebum, apocrine sweat and pheromones; impact on social and sexual interactions; thermoregulation and being a resource for stem cells. Hair is a derivative of the epidermis and consists of two distinct parts: the follicle and the hair shaft. The follicle is the essential unit for the generation of hair. The hair shaft consists of a cortex and cuticle cells, and a medulla for some types of hairs. Hair follicle has a continuous growth and rest sequence named hair cycle.

The stomach is a muscular, J-shaped organ in the upper part of the abdomen. It is part of the digestive system, which extends from the mouth to the anus. The size of the stomach varies from person to person, and from meal to meal. The stomach is part of the digestive system and is connected to the: esophagus — a tube-like organ that connects the mouth and throat to the stomach.
Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells.
Он хотел говорить, но слова застревали у него в горле. Он протягивал свою изуродованную руку… пытаясь что-то сообщить. Танкадо хотел спасти наш банк данных, - говорила она. - А мы так и не узнаем, как это сделать. - Захватчики у ворот.
