3. The human body can be divided into several regions, each serving specific functions and housing vital organs. These regions are commonly referred to as anatomical regions Regions of the Body 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 3

4. The head is the uppermost part of the body and houses the brain, eyes, ears, nose, and mouth. It is connected to the neck, which supports the head and allows for movements like nodding and turning. Head and Neck 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 4

5. The thorax is located between the neck and the abdomen, protected by the ribcage. It contains important organs like the heart and lungs, vital for respiration and circulation. Thorax (Chest ) 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 5

6. The abdomen is the region between the thorax and the pelvis. It contains various organs, including the stomach, liver, intestines, and kidneys, involved in digestion and waste elimination. Abdomen 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 6

7. These include the arms, extending from the shoulders to the hands, and contain structures like bones, muscles, nerves, and blood vessels. Upper Limbs 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 7

8. The lower limbs comprise the hips, legs, and feet, supporting body weight and facilitating movement. Lower Limbs 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 8

9. The human body contains several cavities that house and protect internal organs. Understanding these cavities is crucial for healthcare professionals and diagnostic procedures . Body Cavities 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 9

10. Located within the skull, the cranial cavity houses the brain, protecting it from external trauma and providing a secure environment. Cranial Cavity 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 10

11. Enclosed by the ribcage, the thoracic cavity houses the heart and lungs . A thin, double-layered membrane called the pleura lines the thoracic cavity and covers the lungs. Thoracic Cavity 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 11

12. This large cavity is divided into two portions: the upper abdominal cavity and the lower pelvic cavity. The abdominal cavity houses organs like the stomach, liver, spleen, and intestines, while the pelvic cavity contains the reproductive organs, urinary bladder, and rectum.

13. The spinal cavity runs along the length of the vertebral column and protects the spinal cord, which is a crucial part of the central nervous system. Spinal (Vertebral) Cavity 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 13

14. The human body functions as an integrated system, with various organ systems working together to maintain homeostasis and ensure the body's survival. Systems of the Body 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 14

15. The nervous system is responsible for transmitting signals throughout the body, allowing communication between different organs and coordinating voluntary and involuntary actions. It comprises the brain, spinal cord, and nerves. Nervous System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 15

16. Respiratory System The respiratory system facilitates the exchange of oxygen and carbon dioxide between the body and the environment. It includes the lungs, trachea, bronchi, and diaphragm. 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 16

17. The circulatory system, also known as the cardiovascular system, is responsible for transporting blood, oxygen, nutrients, and hormones throughout the body. It includes the heart, blood vessels, and blood. Circulatory System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 17

18. The digestive system processes food and absorbs nutrients, essential for providing energy and maintaining bodily functions. It consists of organs such as the mouth, oesophagus, stomach, intestines, and liver. Digestive System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 18

19. The musculoskeletal system provides structure, support, and movement to the body. It includes bones, muscles, ligaments, and tendons. Musculoskeletal System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 19

20. The urinary system filters waste products from the blood and eliminates them from the body through urine . It comprises the kidneys, ureters, bladder, and urethra. Urinary System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 20

21. The reproductive system is responsible for procreation and passing on genetic material to the next generation. It includes the male and female reproductive organs. Reproductive System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 21

22. The skeletal system provides structural support, protection to internal organs, and facilitates movement. It consists of bones, cartilage, ligaments, and tendons. Bones store minerals and produce blood cells in the bone marrow. Skeletal System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 22

23. The integumentary system is the body's outermost layer, including the skin, hair, and nails. It protects the body from external elements, regulates temperature, and contains sensory receptors. Integumentary System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 23

24. The lymphatic system plays a vital role in immunity and fluid balance . It includes lymph nodes, lymph vessels, and lymphatic organs like the spleen and thymus. The system helps remove waste, toxins, and foreign substances from the body and aids in fighting infections. Lymphatic System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 24

25. The endocrine system is a collection of glands that produce and secrete hormones directly into the bloodstream. These hormones regulate various physiological processes such as metabolism, growth, reproduction, and stress response. Endocrine System 21-07-2023 BY- Assist. Proff. Dr. Dheeraj Kumar 25

26. The immune system is responsible for defending the body against harmful pathogens like bacteria, viruses, and parasites. It consists of specialized cells, tissues, and organs like white blood cells, lymph nodes, thymus, and spleen, working together to identify and destroy foreign invaders while distinguishing them from the body's own cells.
