Introduction
Listed below are the summary points you will learn in the subsequent 10 lessons of this course.
Lesson 1: Introduction to Human Anatomy
- Human anatomy is the study of the structure and function of the body's systems, organs, and tissues.
- The body is divided into several major systems, including the skeletal, muscular, nervous, and circulatory systems.
Lesson 2: Skeletal System
- The skeletal system is made up of bones and joints, which provide support and movement for the body.
- The main parts of the skeletal system include the skull, spine, ribcage, and limbs.
- The bones are connected to one another by joints, which allow for movement.
Lesson 3: Muscular System
- The muscular system is made up of muscles, which provide movement and support for the body.
- Muscles are grouped into three types: skeletal, smooth, and cardiac.
- Skeletal muscles are attached to bones and are responsible for voluntary movement.
- Smooth muscles are found in the walls of internal organs and are responsible for involuntary movement.
- Cardiac muscle is found in the heart and is responsible for pumping blood.
Lesson 4: Nervous System
- The nervous system is responsible for receiving and processing information from the body and the environment.
- The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
- The CNS includes the brain and spinal cord and is responsible for processing and interpreting information.
- The PNS includes the nerves that run throughout the body and is responsible for transmitting information to and from the CNS.
Lesson 5: Circulatory System
- The circulatory system is made up of the heart, blood vessels, and blood, which transport nutrients and oxygen to the body's cells and remove waste products.
- The heart pumps blood through a network of blood vessels, including arteries, veins, and capillaries.
- Blood is composed of plasma, red blood cells, white blood cells, and platelets.
Lesson 6: Respiratory System
- The respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide.
- The main parts of the respiratory system include the nose, trachea, lungs, and diaphragm.
- Air is taken in through the nose or mouth and travels down the trachea to the lungs, where oxygen is exchanged for carbon dioxide.
Lesson 7: Digestive System
- The digestive system is responsible for breaking down food and absorbing nutrients.
- The main parts of the digestive system include the mouth, esophagus, stomach, small intestine, and large intestine.
- Food is broken down by enzymes and stomach acid, and nutrients are absorbed in the small intestine.
Lesson 8: Urinary System
- The urinary system is responsible for removing waste products from the body.
- The main parts of the urinary system include the kidneys, ureters, bladder, and urethra.
- The kidneys filter waste products from the blood, and urine is then transported to the bladder and removed from the body through the urethra.
Lesson 9: Endocrine System
- The endocrine system is responsible for producing and releasing hormones, which are chemical messengers that regulate various bodily functions.
- The main parts of the endocrine system include the pituitary gland, thyroid gland, pancreas, and adrenal glands.
Lesson 10: Immune System
- The immune system is responsible for protecting the body against infection and disease.
- The main parts of the immune system include white blood cells, lymph nodes, and the spleen.
- White blood cells identify and attack foreign invaders, while lymph
