Study Notes
- Organ systems are groups of organs that perform similar functions in the body.
- Organs can be found in specific body cavities or throughout the body.
- Membranes line the cavities and internal spaces of organs and tubes, and are of four types: mucous, serous, synovial, and meninges.
- The human body is divided into two main cavities: the ventral (thoracic, abdominal, pelvic) and dorsal (cranial, vertebral) cavities.
- Organs include the skin (integumentary system), heart and blood vessels (cardiovascular system), lymphatic vessels, lymph nodes, spleen (lymphatic and immune system), oral cavity, esophagus, stomach, small intestine, large intestine, salivary glands, liver, gallbladder, pancreas (digestive system), lungs (respiratory system), kidneys and urinary bladder (urinary system), testes, penis, ovaries, uterus, vagina (reproductive system), bones (skeletal system), brain and spinal cord (nervous system), and endocrine glands (endocrine system).
- Mucous membranes line the tubes of the digestive, respiratory, urinary, and reproductive systems, and secrete mucus that protects the body from invasion by bacteria and viruses.
- Serous membranes line the closed cavities of the body and secrete a watery fluid that keeps the membranes lubricated, supporting the organs and compartmentalizing the large thoracic and abdominal cavities.
- Synovial membranes line the cavities of freely movable joints and secrete synovial fluid into the joint cavity, lubricating the ends of the bones.
- The meninges are membranes within the dorsal cavity that protect the brain and spinal cord.
- The body contains various organ systems that perform specific functions, such as the digestive, respiratory, cardiovascular, lymphatic and immune, urinary, reproductive, skeletal, nervous, and endocrine systems.
- Organs are grouped according to their functions and are found in specific body cavities or throughout the body.
- Membranes line the cavities and internal spaces of organs and tubes, and are of four types: mucous, serous, synovial, and meninges.
- The human body is divided into two main cavities: the ventral (thoracic, abdominal, pelvic) and dorsal (cranial, vertebral) cavities, and contains various organs including the heart, lungs, stomach, liver, kidneys, and brain.
- Mucous membranes secrete mucus that protects the body from bacteria and viruses, while serous membranes secrete fluids that lubricate the organs and support them.
- Synovial membranes secrete synovial fluid that lubricates joints, and the meninges are protective membranes surrounding the brain and spinal cord.
- Organs perform specific functions within their respective organ systems, and are supported and protected by the body's cavities and membranes.
