Biology- Body Systems and Homeostasis

Homeostasis

Tendency to resist change in orger to maintains a stable, relatively constant internal environment

Regulation of body’s internal conditions

Temperature, glucose levels, and blood pressure

Postive Feedback Loops 

Response to a stimulus keeps increasing the change

Pushes the system further in the same direction until a specific result is reached 

Negative Feedback Loops

Reverse change in the body

Slow on stops decreases output

Brings the body back to normal

More common then positive feedback Loops

Circulartory System Organs

Heart, blood and vessls

Circulatory System functions 

Transport blood, which delivers oxygen and nutrients throughout the body 

Nervous system Organs

Brain, Spinal cord, and nerves

Nervous System Functions

Responsible for all bodily functions, relays message, processes information, analyzes response

Muscular System Organs 

All muscles

Musclular System Fucntions

Faciliates all movement

Resoratory System Organs

lungs, trachea, nose, mouth, and diaphragm

Resporatory System Functions 

Breathing (intake of oxygen and release of Carbon Dioxide)

Digestive System Organs

Stomach, Mouth, Pharmk, Esophagus, and Small and Large intestine 

Digestive System Functions

Break down of food absorption of nutrients

Skeletal System Organs

206 bones, joints, bone marrow

Skeletal System Functions 

Suports, protect, blood cells production, storage of minerals 

Immune System Organs 

Lymph rodes, tonsils, spleen, thymus, lymphatic tissues, specialized cells

Immune System Functions

Protect against and fight disease/illness

Endocrine System Organs

Hypthalamous, pineal glad, pituitary gland, thyroid, parathyroid, thymus, renal glands and pancreas

Endorcrine System Functions

Hormone production and release to send measure throughout the body

Excretory System Organs 

Kidneys, bladder, liver, large intestine, rectum, and skin 

Excretory System Fuctions

Removal of waste and toxins from the body

Integumentary System Organs

Skin, hair, glands, and nails

Intergumentary System Functions 

Cover protect the body, control water loss, and regulation of temperature 

Reproductive System Organs

Male- Prostate, vas deferments, penis, testicles

Females- Uterus, overrides fallobian tubes, cervix, and vagina
