1. Integumentary System:
* Organs: Skin, hair, nails
* Functions: Protection, regulation of body temperature, excretion, sensation
2. Skeletal System:
* Organs: Bones, cartilage, ligaments, joints
* Functions: Support, movement, protection of internal organs, mineral storage, blood cell production
3. Muscular System:
* Organs: Muscles (skeletal, smooth, cardiac)
* Functions: Movement, posture, heat production
4. Nervous System:
* Organs: Brain, spinal cord, nerves
* Functions: Control and coordination of body functions, sensory perception, thought, emotion
5. Endocrine System:
* Organs: Glands (pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries/testes)
* Functions: Production and secretion of hormones that regulate growth, metabolism, reproduction, and other processes
6. Cardiovascular System:
* Organs: Heart, blood vessels (arteries, veins, capillaries)
* Functions: Transport of blood, oxygen, nutrients, and waste products throughout the body
7. Lymphatic System:
* Organs: Lymph nodes, lymphatic vessels, spleen, thymus, bone marrow
* Functions: Immune response, fluid balance, waste removal
8. Respiratory System:
* Organs: Lungs, trachea, bronchi, nose
* Functions: Gas exchange (oxygen intake, carbon dioxide removal)
9. Digestive System:
* Organs: Mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, gallbladder
* Functions: Breakdown of food, absorption of nutrients, elimination of waste
10. Urinary System:
* Organs: Kidneys, ureters, bladder, urethra
* Functions: Filtration of blood, production and excretion of urine, regulation of blood pressure and electrolyte balance
11. Reproductive System (Male & Female):
* Organs: Male - testes, penis, prostate; Female - ovaries, uterus, vagina
* Functions: Production of sex hormones, reproduction
These systems are interconnected and work together to maintain homeostasis, the body's internal balance. Any disturbance in one system can affect the others, highlighting the importance of overall health and well-being.
