hello folks in this video we are going to introduce each of the major organ systems we'll just run through some of the major organs in each system and their main functions and then throughout the course we are going to get through and look at each of these organ systems in more detail so to start off we have the integumentary system the major organ of the integumentary system is the skin the hair and nails and other structures within the skin such as sensory receptors are also part of this system as we know the integument covers the body and its major function is really protection the integumentary system plays important roles in helping to regulate body temperature and as well as sensing changes in the environment the skeletal system is made up of your bones as well as joints ligaments and cartilages the major functions are support protection and movement in addition the skeletal system is also an important storage location for inorganic salts and it houses the tissues of where blood cells are made the muscular system consists of your skeletal muscles and tendons the muscular system provides movement and supports posture it's also very important in heat production the nervous system consists of your brain spinal cord peripheral nerves and three organs so really the function of your nervous system is to detect and interpret stimuli and coordinate the body's responses to those stimuli the nervous system then acts by stimulating glands or muscles and that's how it initiates responses the endocrine system works with the nervous system to control body processes the endocrine system includes all hormone producing structures in the body which is quite a few however the the major endocrine organs that we're just going to list for now are the pituitary gland the thyroid gland adrenal glands pancreas ovaries and testes along but as I mentioned along with the nervous system the endocrine system helps to regulate various bodily processes through the secretion of hormones will see that the nervous and endocrine systems really do this together on the nervous system acts faster whereas the hormonal effects of the endocrine system are generally more long-term the cardiovascular system includes the heart blood and blood vessels the major function is the utilization of the blood to transport oxygen and nutrients to the body tissues of course other things such as hormones are also transported through the blood and then the blood takes up waste from cells and helps remove those wastes from body tissues so the lymphatic system is probably one of the systems that people are less familiar with but it's very important the major organs of the lymphatic system are going to be the lymphatic vessels which largely parallel blood vessels moving throughout the body lymph nodes and then the immune organs of thymus and the spleen so the major and immune cells so the major functions of the lymphatic system number one it drains and filters interstitial fluid so interstitial fluid is the name of the fluid that bathes all the tissues of your bodies okay so the fluid is constantly that bathes the tissues is constantly drained into the lymphatic vessels the other important component of the lymphatic system is the immune system so the immune system is actually part of the lymphatic system so all of the cells and organs that we associate with the immune response are part of the lymphatic system and as such they play critical roles in defending us against infections next we have the respiratory system there are quite a few structures in the respiratory system the nose trachea lungs pharynx the major function of the respiratory system is the exchange of gases oxygen is co2 between the body and the external environment a digestive system once again has many organs that are part of it also includes the mouth and the pharynx as well as stomach small and large intestines the liver and others the functions of the digestive system are to receive break down and absorb nutrients from food and then eliminate any waste materials that can be broken down the urinary system consists of the kidneys ureters the bladder and the urethra the kidneys as we'll learn later on the kidneys have many many important functions in the body but overall some of the sort of the general functions include filtering the blood in order to maintain the proper fluid levels and electrolyte balance in the body as well as removing waste products we have the reproductive system for men the major organs are going to be the testes and epididymis and for women you have the ovaries and the uterus are the major organs the functions for both are to produce maintain and transport the gametes which is the sperm in the egg as well as production of hormones the female reproductive system of course has the additional function of housing the developing embryo and then of course is involved in the birth process so we will learn about all of these organ systems in much more detail in the coming weeks and months
