Human Body
Levels of organization (works with whole body)
Organs are groups of tissue which work in systems and all have their own part
Organ System is a group of organs working together to perform a function and maintain homestasis
Tissue are cells in groups
Organism
Cells are the basic unit of life
immune system
Second line
It works closely with the circulatory system for transportation needs
White blood cells help the body fight infection and other diseases.
Inflammatory response causes blood vessels to leak fluid into the tissues, causing swelling
T-cells focuses on specific foreign particles
Phagoctyes surround and kill microorganisms, ingest foreign material, and remove dead cells
First line
Musuc
Circulatory system
heart, produces blood so other organs function.
blood transporting oxygen and nutrients to the lungs and tissues
arteries carry blood that has oxygen and nutrients in it.
blood vessels ransport nutrients to organs/tissues and to transport wastes away from organs/tissues in the blood.
veins collect oxygen-poor blood throughout your body and carry it back to your heart
Skeletal system
Bones provides support for the body
Connective Tissue adds structure to tissue
Tendons move the bone
Ligaments hold structure together
adds support (bones) to stand

digestive system
large intestine turns food waste into stool and passes it from the body when you poop.
pancreas helps your body break down food
mouth meant for eating
esophagus transport food entering the mouth through the throat and into the stomach
Liver breaks down, balances, and creates the nutrients
Removes waste and absorbs nutrients
Stomach takes in food from the esophagus (gullet or food pipe), mixes it, breaks it down, and then passes it on to the small intestine in small portions
small intestine helps to further digest food coming from the stomach.
recton stores feces until a person is ready to have a bowel movement.
Endocrine
Pancreas helps your body break down food
Thyroid support the rate at which the body uses fats and carbohydrates.
Adrenal Glands produce hormones that help regulate your metabolism
Testes and Ovaries produce eggs for fertilization and they make the hormones estrogen and progesterone.
Endocrine glands releases hormones to blood stream
Muscular system
skeletal contract to produce movement,
Smooth helps with digestion and nutrient collection
Cardiac responsible for the contractility of the heart and, therefore, the pumping action.
Sends signals to body
controls muscles so we can move
Nervous system
Nerves carry electrical impulses between your brain and the rest of your body.
Brain controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.
Spinal cord the pathway for messages sent by the brain to the body and from the body to the brain.
Urinary system
ureters carry urine from the kidneys to the bladder.
kidneys filter your blood
Urethra empties urine from the bladder.
bladder stores urine.
urine is waste that needs to be released from the body.
Reproductive
ovaries produce hormones that help with your menstrual cycle and pregnancy.
uterus nourish and house a fertilized egg until the fetus, or offspring, is ready to be delivered.
gamete carry out fertilization in sexually reproducible organisms
sperm reach the ovum and fuse with it to deliver two sub-cellular structures
eggs have sex with sperm to reproduce
urethra empties urine from the bladder.
produces egg and sperm to reproduce
Respiratory system
nose allows air to enter your body, then filters debris and warms and moistens the air.
mouth helps with eating and speaking
voice box breathing, swallowing, and talking.
throat acts as the passageway for air, food and liquid
wind pipe carry oxygen-rich air to your lungs
lungstake in oxygen and expand, and takes out CO2
diapghram separates the abdomen from the chest
soft tissue connect and support other tissues and surround the organs in the body.
allows us to breathe and maintain homeostasis
The urinary system's function is to filter blood and create urine as a waste by-product.

The immune system is a system that protects you from sickness
works with digestive and excretory systems
works with digestive system
works with digestive system because it enables walls to move
It works with the circulatory system
The reproductive system requires oxygen in order to work properly, and the respiratory system provides the reproductive system with the oxygen it needs.
works with nervous sytem
works with the muscular system
works with muscular system
carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
works with the respiratory system
