Organ Systems (S7L2.e)

This was probably the longest part of Unit 2. It was easy, but the stuff we had to do for it was kind of hard. There are 9 major organ systems in the body: respiratory, circulatory, digestive, reproductive, nervous, excretory, integumentary, endocrine, skeletal, and muscular. Together, these 9 organ systems work together to keep us alive. 

Muscular System- helps you move, transports blood throughout the body, and keeps waste going through the digestive system. Organs include: smooth muscle, cardiac muscle, skeletal muscle

Skeletal System- bones support the body and protect the fragile organs within. Includes: bones, cartilage, ligaments, tendons,  bone marrow

Circulatory System (or Cardiovascular)- pumps blood throughout the body, distributing water and nutrients while taking away wastes from cells and organs. Includes: heart, blood vessels, blood, lungs, and cardiac muscle

Reproductive System (Alright alright alright! We gon learn today what a  (censor beep here) is!)- *NOTE: turn off your negative mind* responsible for allowing humans to reproduce, thus keeping our species alive. Includes: egg, sperm, testes, ovaries, penis, vagina, and prostate.

Respiratory System- intakes oxygen from the air around us while releasing carbon dioxide as waste. Includes: lungs, heart, blood, blood vessels, and bronchi.

Digestive System- breaks down food into a state that's usable for cells. Includes: stomach, esophagus, large and small intestines, and salivary glands.

Excretory System- rids the body of unneeded wastes. Includes: large intestine, sweat glands, bladder, vagina, penis

Nervous System- collects, transfers, and processes information with the brain. Includes: eyes, ears, mouth, nose, skin, taste, spinal cord, and brain.

Lymphatic System- filters the blood of wastes using the clear fluid called lymph. Includes: lymph nodes, lymph vessels, capillaries, lymph ducts, and lymph capillaries.

Endocrine System- communication for what to do within the body using hormones. Includes: pituitary gland, adrenal gland, thyroid, pineal gland, and parathyroid.

Hope you enjoyed this section of reviewing S7L2!
