Human Body Systems Interactions

THE HUMAN BODY SYSTEMS System Digestive Function To Digest food to provide to the muscles, to remove waste, and to grow. Diagram Major Organs Mouth, esophagus, stomach, Sm. Intestine, Lg. intestine, rectum, anus Salivary glands, pancreas, liver, gall bladder T tTo Circulatory bring oxygen to places in the human body that need it for as long as the heart pumps, letting the oxygen be refilled in the red Heart, Arteries, Viens, Red blood Cells, and Capillaries. blood cells. Nervous InteractionsWorking with Other Systems 1. w/circulatory – absorb & deliver the digested nutrients to the cells 2. w/muscular – control the contractions of many of the digestive organs to pass food along 3.w/nervous – hypothalamus maintains homeostasis by triggering appetite (stomach growling), digest. 1. w/respiratory – deliver O2 from lungs to cells and drop off CO2 from cells to lungs 2. w/digestive – absorb and deliver digested nutrients to cells 3. w/excretory – kidneys filter cellular waste out of blood for removal 4. w/lymphatic – both transport things to and from cells 5. w/immune – transports WBCs throughout body to fight disease 6. w/nervous – brain controls heartbeat 7. w/endocrine – trans. hormones Controls all other systems To sends signals Brain, Spinal through the whole body to control other body systems. Cord, and Nerve Cells. Hypothalamus – maintains homeostasis by working with all systems System Function Excretory To filter and excrete waste out of the blood and the rest of the body. Respiratory To breathe in oxygen and breathe out carbon dioxide as a waste. To supply yourself with oxygen and get rid of CO2. Skeletal To provide support and structure to your body, make red blood cells, etc. Diagram InteractionsWorking with Other Systems Kidneys, urinary 1. w/circulatory – filters waste out of blood bladder. 2. w/lungs – removes excretory waste 3. w/integumentary – removes excretory waste Major Organs Nasal and Oral 1. w/circulatory – takes in O2 for delivery to cells Cavity, Pharynx, Larynx, Trachea, Luns, Bronchi, Bronchioles, and Alveoli. Bones and removes CO2 brought from cells 2. w/excretory – removes excretory waste 3. w/nervous – controls breathing 4. w/muscular – diaphragm controls breathing 1. w/muscular – allow movement 2. w/circulatory – produce blood cells 3. w/immune – produce white blood cells 4. w/circulatory and respiratory – protects it’s organs System Function Muscular To provide strength to bones, giving you Diagram Major Organs Muscles 1. w/skeletal – allow movement 2. w/digestive – allow organs to contract to push food through 3. w/respiratory – diaphragm controls breathing 4. w/circulatory – controls pumping of blood (heart) 5. w/nervous – controls all muscle contractions Glands *Hypothalamus *Pituitary *Thyroid *Thymus *Adrenal *Pancreas *Ovaries *Testes 1. w/circulatory – transports hormones to target organs 2. w/nervous – maintain homeostasis, hormone release 3. w/reproductive – controlled by hormones 4. w/skeletal – controls growth of bones the ability to move, etc. Endocrine Regulates body activities using hormones. Slow response, long lasting Glands produce Hormones Immune Fights off foreign invaders in the body InteractionsWorking with Other Systems White Blood Cells *T cells *B cells -produce antibodies *Macrophages Skin 1. w/circulatory – transports WBCs to fight invaders 2. w/lymphatic – has lots of WBCs to fight invaders, spleen filters bacteria/viruses out of blood 3. w/skeletal – WBCs made in bone marrow 4. w/integumentary – prevents invaders from getting in System Integumentary Lymphatic Function 1. barrier against Infection (1st line of defense) 2. helps regulate body temp. 3. removes excretory waste (urea, water) 4. protects against sun’s UV rays 5. produces vitamin D 1. stores and carries WBC’s that fight disease 2. collects excess fluid and returns it to blood (2nd circulatory system-reaches places other one can’t – between cells) Diagram Major Organs Skin, Hair, and Nails Lymph (liquid part of blood – plasma, when it’s in lymph vessels) Lymph Vessels Lymph Nodes Contain WBCs InteractionsWorking with Other Systems 1. w/excretory – removes cellular waste 2. w/nervous – controls body temperature (sweating, goose bumps) 3. w/immune – prevents pathogens from entering 1. w/immune – holds lots of WBCs to fight pathogens 2. w/circulatory – to transport materials to and from cells
