PRESENTATION OUTLINE
Cardiovascular System
- Transports oxygen throughout the body
- Pathway of blood: Superior and inferior vena cava-Right atrium-Tricuspid valve-Right ventricle-Pulmonary valve-Pulmonary artery-Lungs-Pulmonary vein-Left atrium-Bicuspid valve-Left ventricle-Aortic valve-Aorta
- 4 Cambers: Right Atrium: Receives oxygen-poor blood from body, goes to right ventricle Left Atrium: Receives oxygen-rich blood from lungs, goes to left ventricle. Right Ventricle: Pumps oxygen-poor blood into lungs. Left Ventricle: Pumps oxygen-rich blood into the body

Digestive System
- Converts food to energy
- Mouth: Breaks food down
- Esophagus: Carries food, liquid, and saliva from the mouth to the stomach
- Stomach: Further breaks down food to pass to the small intestine
- Small intestine: absorbs minerals and nutrients
- Large intestine: Further separates nutrients and fecal matter
- Colon: Reabsorb fluids and start to eliminate waste

Endocrine System
- Maintains body's homeostasis
- Pituitary gland: Releases hormones, some that can control other endocrine glands
- Hypothalamus: Make ADH and oxycoton and other hormones that can control the Pituitary gland
- Thymus: stimulates development of T cells for the immune system

Immune System
- Body's defense system from infections
- Bone marrow: Contains cells for B lymphocytes
- Spleen: Filters to remove debris and antigens to foster contact with T lymphocytes
- Lymph nodes: Filters to remove debris and antigens to foster contact with T lymphocytes

Integumentary System
- Top layers of skin on body, protects from damage
- Epidermis: Waterproof barrier and skn tone
- Dermis: hair follicles and sweat glands
- Hypodermis: Has connective tissue and fat

Muscular System
- Responsible for movement in body
- Major Muscles: Triceps, biceps, deltoids, pectorals, obliques, quadriceps, abdominals, gluteus maximus, lattemius dorsi, rotator cuff, gastrocnemius, soleus

Nervous System
- Controls body communications
- Brain: Executes voluntary motor responses, and regulates homeostasis
- Spinal cord: Initiates reflexes and "middleman" between sensory and motor functions from brain-periphery
- Digestive tract: Responsible for autonomus functions

Reproductive System (F)
- Produces and transports gametes
- Pathway: Ovary-fallopian tube-uterus-cervix-vagina

Reproductive System (M)
- Produces sperm
- Pathway: Testes-epididymis-deferent duct-spematic cord-pelvic cavity-ureter-prostate

Respiratory System
- Provides oxygen to body
- We need oxygen to burn sugars and fatty acids in our cells to make energy, in turn making us breathe

Skeletal System
- Provides structure and protection to the body
- Major Bones: rib, sternum, femur, tibia, fibula, pelvis
