System Digestive Interactions 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. Circulatory 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/nervous – brain controls heartbeat Nervous Controls all other systems Excretory 1. w/circulatory – filters waste out of blood 2. w/respiratory – removes excretory waste Respiratory 1. w/circulatory – takes in O2 for delivery to cells and removes CO2 brought from cells 2. w/excretory – removes excretory waste 3. w/nervous – controls breathing 4. w/muscular – diaphragm controls breathing Skeletal 1. w/muscular – allow movement 2. w/circulatory – produce blood cells 3. w/circulatory and respiratory – protects organs Muscular 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 Interactions between the Nervous System and… The Skeletal System: Bones provide calcium that is essential for the proper functioning of the nervous system. The skull protects the brain from injury. The vertebrae protect the spinal cord from injury. Sensory receptors in joints between bones send signals about body position to the brain. The brain regulates the position of bones by controlling muscles. The Circulatory System: Endothelial cells maintain the blood-brain barrier. Baroreceptors send information to the brain about blood pressure. Cerebrospinal fluid drains into the venous blood supply. The brain regulates heart rate and blood pressure The Muscular System: Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract. The Respiratory System: The brain monitors respiratory volume and blood gas levels. The brain regulates respiratory rate. The Digestive System: Digestive processes provide the building blocks for some neurotransmitters. The autonomic nervous system controls the tone of the digestive tract. The brain controls drinking and feeding behavior. The brain controls muscles for eating and elimination. The digestive system sends sensory information to the brain. The Excretory System: The bladder sends sensory information to the brain. The brain controls urination. Cardiovascular and Respiratory Systems The cardiovascular system with its heart-pump and network of arteries and veins shuttles oxygen-rich blood from the lungs to all of the body's organs and tissues. Cells throughout the body take their fill of oxygen and nutrients and dispose of carbon dioxide and waste products, which eventually flow back to the heart's right-sided chambers; then on to the lungs to exchange carbon dioxide with oxygen. Inhaled air passes through your nasal passages, throat and lung airways reaching tiny alveoli, the site of gas exchange. The newly oxygen-rich blood travels back from the lungs to the heart's left-sided chambers, where it gets pumped out at great pressure via arteries to reach the needy tissues once again. And so the cycle continues. Digestive and Excretory Systems The digestive system is responsible for breaking down food into molecules small enough to be used by the body's cells and tissues. The food is broken apart through chewing and stomach churning, but also chemically -- through the stomach's acid-loving enzymes, and on to the small intestine, which receives pancreatic enzymes and juices specially tailored to dissolve and digest proteins, carbohydrates and fibers. Bile from the liver also works on fats. Though absorption of some drugs and alcohol may start in the stomach, absorption is mainly the function of the small intestines. Digestible nutrients pass through from the small intestines and their microvilli to capillaries and on to the liver for detoxification and further processing and conditioning, then out to the body. Fibers, undigestible material, bile and loads of bacteria travel through the large intestines and out through the colon and rectum. The kidneys filter out wastes from the blood to form urine, which flows down the ureters and enters the urinary bladder. The bladder collects the urine and releases when full, out through the urethra. Skeletal and Muscular Systems The system that provides your body's shape is the skeletal system, and it is made up of cartilage and bone. There are 206 bones in the human skeleton that provide a hard framework able to support the body and protect the organs that they surround. Cartilage provides support with flexibility and resistance, and acts as padding to soften the pressure that is exerted from the bones. Movement in the body is the result of muscle contraction; when muscles combine with the action of joints and bones, obvious movements are performed, such as jumping and walking. The contraction of muscles provides the body posture, joint stability and heat production
