Chapter 1 Part 2 Organ Systems


This lecture will provide an introduction to anatomy and physiology. In this segment, 2 of 4… We will cover the organ systems found in the human body. This course will cover 11 organ systems found in the human body. The integumentary system, skeletal system, muscular system, nervous system, endocrine system, cardiovascular system, the lymphatic system, respiratory system,
digestive system, urinary system, and reproductive system. The following slides will serve as a brief
introduction to each system, beginning with the integumentary system. The Integumentary System is composed of the skin, hair, and nails. It’s functions include protection from the external environment, and the regulation of the body temperature. The Skeletal System is composed of bones, cartilages, joints, ligaments, and other connective tissues. Its functions include support, protection, mineral storage, and the formation of blood cells. The Muscular System is composed of the muscles and tendons of the body. Its functions include movement, support, and the production of heat. The Nervous System is composed of the Central and Peripheral Nervous Systems and
their components, including the brain, spinal cord, and peripheral nerves. Its functions include responding to stimuli and coordinating the response of other organ systems. The Endocrine System consists of various endocrine organs and organs
that have various different functions. The function of the endocrine systems include directing long term changes and the activities of
other organ systems. The Cardiovascular System consist of
the heart vessels and blood. Its functions include transportation of nutrients, waste, and gases; PH regulation, and body defense. The Lymphatic System includes Lymph nodes, nodules, vessels, and organs. Its function include defense and aiding
in tissue fluid regulation. The Respiratory System includes the nose, pharynx, trachea, bronchi, and the lungs. Its functions include providing a sight for gas exchange and sound production. The Digestive System is composed of the organs and accessory organs found along the digestive track, including the salivary glands, tongue, pharynx, esophagus, liver, stomach, pharynx, small and large intestines, and the anus. Its functions include the processing of food and the absorption of nutrients. The Urinary System is composed of the kidneys, ureters, urinary bladder, and the urethra. Its functions include eliminating waste from the body, regulating PH, and regulating blood volume. The Male Reproductive System is composed of the scrotum, testis, penis, epididymis, Ductus deferens, and several glands. Its functions include producing sex cells
and hormones. The Female Reproductive System includes the external genitalia, vagina, uterus, uterine tubes, ovaries, and mammary glands. Its functions include producing sex cells
and hormones, supporting embryo and fetus development, and providing nourishment for a newborn. Again, the 11 organ systems of the human body are the integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems. Each of these systems will be covered in great detail in this course. It is important to keep in mind that all of the organ systems work together to attempt to maintain the health and
well-being of an individual.
