Circulatory SystemCirculatory System

The major The major organs of the organs of the circulatory circulatory system include system include blood vessels blood vessels and the heartand the heart

Circulatory SystemCirculatory SystemThe circulatory The circulatory system transports system transports nutrients and nutrients and waste throughout waste throughout the bodythe body

Circulatory SystemCirculatory SystemTo help maintain To help maintain homeostasis, the homeostasis, the circulatory system circulatory system regulates and regulates and maintains the maintains the correct levels correct levels nutrients, oxygen, nutrients, oxygen, and waste products and waste products needed by cellsneeded by cells

Vascular Tissue SystemVascular Tissue SystemSimilar to the Similar to the circulatory system circulatory system in animals, the in animals, the vascular tissue vascular tissue system regulates system regulates and maintains and maintains correct levels of correct levels of nutrients and nutrients and waste products waste products needed by plant needed by plant cellscells

Vascular Tissue SystemVascular Tissue SystemThe major organs The major organs of the vascular of the vascular tissue system are tissue system are xylem and phloemxylem and phloem

– xylem transports xylem transports waterwater

– phloem transports phloem transports foodfood

Vascular Tissue SystemVascular Tissue SystemThe vascular tissue system acts as a The vascular tissue system acts as a plumbing system that carries fluids and plumbing system that carries fluids and dissolved substances throughout plants.dissolved substances throughout plants.

Digestive SystemDigestive SystemThe major organs The major organs of the digestive of the digestive system include system include the mouth, the mouth, esophagus, esophagus, stomach, large stomach, large and small and small intestines, and the intestines, and the coloncolon

Digestive SystemDigestive System

The digestive The digestive system absorbs system absorbs nutrients by nutrients by breaking down breaking down food into usable food into usable biomoleculesbiomolecules

Digestive SystemDigestive SystemThe digestive system The digestive system contributes to homeostasis contributes to homeostasis by regulating the intake of by regulating the intake of nutrients, breaking down nutrients, breaking down food molecules and food molecules and absorbing them into the absorbing them into the cells, and regulating water cells, and regulating water intake (large intestine)intake (large intestine)

Excretory SystemExcretory SystemThe major organs The major organs of the excretory of the excretory system include the system include the kidneys, liver, kidneys, liver, bladder, colon, bladder, colon, rectum, lungs, and rectum, lungs, and skinskin

Excretory SystemExcretory SystemThe excretory The excretory systems removes systems removes waste from the waste from the bodybody

Excretory SystemExcretory SystemThe excretory system helps The excretory system helps maintain homeostasis by maintain homeostasis by removing all waste material removing all waste material from the body; the skin from the body; the skin sweats (which also helps to sweats (which also helps to cool the body); the kidneys cool the body); the kidneys filter chemicals in the blood; filter chemicals in the blood; the liver filters toxins and the liver filters toxins and acids from the blood; and the acids from the blood; and the colon allows solid waste to colon allows solid waste to pass from the bodypass from the body

Respiratory SystemRespiratory SystemThe major organs The major organs of the respiratory of the respiratory system include the system include the lungslungs

Respiratory SystemRespiratory SystemThe respiratory The respiratory system moves system moves oxygen into the oxygen into the body while body while removing carbon removing carbon dioxide (COdioxide (CO22) from ) from the bodythe body

Respiratory SystemRespiratory SystemThe respiratory The respiratory system helps system helps maintain maintain homeostasis by homeostasis by bringing in bringing in necessary levels of necessary levels of oxygen while oxygen while removing harmful removing harmful COCO22

Skeletal SystemSkeletal SystemThe skeletal The skeletal system is system is composed of bonescomposed of bones

Skeletal SystemSkeletal SystemThe skeletal The skeletal system protects system protects and supports other and supports other body systemsbody systems

Skeletal SystemSkeletal SystemThe skeletal system helps The skeletal system helps maintain homeostasis by maintain homeostasis by supporting organs and supporting organs and keeping them in place keeping them in place which allows for proper which allows for proper function and directly function and directly interacts with musclesinteracts with muscles

Muscular SystemMuscular SystemThe muscular The muscular system includes system includes voluntary and voluntary and involuntary involuntary musclesmuscles

Muscular SystemMuscular SystemThe muscular The muscular system allows for system allows for movementmovement

Muscular SystemMuscular SystemThe muscular system The muscular system helps maintain helps maintain homeostasis by allowing homeostasis by allowing movement and the body movement and the body to return back into place to return back into place after changing position; after changing position; many involuntary many involuntary muscles constantly muscles constantly regulate body functions regulate body functions such as breathing and such as breathing and heartbeatheartbeat

Endocrine SystemEndocrine System

The major organs of the The major organs of the endocrine system include endocrine system include glands and the brainglands and the brain

Endocrine SystemEndocrine SystemThe endocrine The endocrine system regulates system regulates and sends and sends hormones hormones throughout the throughout the bodybody

Endocrine SystemEndocrine SystemThe endocrine The endocrine system is system is responsible for responsible for regulation from the regulation from the hormone messages hormone messages such as such as temperature, temperature, hunger, sleep, etc.hunger, sleep, etc.

Nervous SystemNervous SystemThe major organs The major organs of the nervous of the nervous system include system include nerves and the nerves and the brainbrain

Nervous SystemNervous SystemThe nervous The nervous system sends system sends chemical chemical messages messages throughout throughout the bodythe body

Nervous SystemNervous SystemThe nervous system The nervous system helps maintain helps maintain homeostasis by sending homeostasis by sending chemical messages to chemical messages to the brain that tell the the brain that tell the status of pain, status of pain, temperature, hunger, temperature, hunger, etc. so that the body etc. so that the body can make adjustments can make adjustments using other systemsusing other systems
