Follow along with your Organ System Chart to record the basic description and function of each system.
What is homeostasis?
The internal human body maintains homeostasis and/or is homeostatic.
What is homeostatic or homeostasis? Stable despite changes in the outside environment.
How do we maintain homeostasis? Major body systems provide cells with oxygen and nutrients and remove toxic waste products such as carbon dioxide.
11 Major Body Systems: Skeletal Muscular Integumentary Cardiovascular Respiratory Immune Digestive Excretory Nervous Endocrine Reproductive
What do they do?
The Skeletal System Bones Structure & Support Protect Organs
The Muscular System Muscles Structure & Support Moves Substances through Body
The Integumentary System Skin, Hair, Nails Protects against Pathogens Regulates Temp.
The Cardiovascular System Heart, Blood, Blood Vessels Transports Nutrients and Wastes to and from all Body Tissue
The Respiratory System Air Passages & Lungs Air exchange in Lungs Oxygen & CO2
The Immune System Lymph Nodes and Vessels White Blood Cells Protects against infection & disease
The Digestive System Stores Digests Absorbs Eliminates Waste
The Excretory System Kidneys Bladder Ureters Urethra Skin Lungs Eliminate Waste Maintains Water & Chemical Balance (Homeostasis!!!)
The Nervous System Brain, Spinal Cord, Nerves, Sense Organs, Receptors Coordinate Movement Consciousness & Creativity Monitors other Organ Systems
The Endocrine System Glands! Regulate: Metabolism Water & Minerals Growth Reproduction Sexual Development
The Reproductive System MALES: Testes (Males) Sperm Production FEMALES: Ovaries & Uterus Mammary Glands Ova and Milk Production
