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

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
