Cell, tissue, organ, organ system, organism

The 3 main parts of The Circulatory system are The Heart Pump blood The Blood Vessels Bring blood around Blood Carry oxygen, nutrients and waste

Circulatory system Functions Carries blood and needed substances (oxygen and nutrients) to cells and waste products away to the cells and all your body. Carries cells that fight disease White blood cells.

Nervous system Main Function: Control for the rest of the systems and body functions Receives information from inside and outside the body Directs the way that the body will respond Main structures brain, spinal cord, nerve cells (neuron), sense organs

Neuron

Reproductive system Function allows more humans to be born to continue the species Main structures egg, sperm, ovaries, testes

Endocrine system Functions produces hormones that control the levels of other substances in the body Structures ductless glands, hormones

Immune system Main function: fights germs entering the body Main parts: lymph, white blood cells, antibodies

Integumentary system Main organ: SKIN Functions Protects the other body systems from injury, infection Helps the body maintain homeostasis synthesis of vitamin D Required for bone formation Excretion of salts, water and wastes sensory perception Main organ: SKIN

Respiratory system Functions Moves oxygen from the outside environment into the body. Removes carbon dioxide and water from the body Main Structure: Lungs Also bronchi, bronchioles, alveoli, nasal cavity, pharynx, larynx, epiglottis, trachea,

To bring oxygen around your body? Oxygen molecules are transport to the cells by the Circulatory system The blood absorb the Oxygen molecules in the lungs that are part of Respiratory system Conclusion the circulatory and the respiratory system work together.

Excretory system Function This system collects the waste produced by the cells and removes the waste from the body. Main organ: Kidneys Others are sweat glands, urinary bladder, urethra, ureter

Digestive system Function Breaks down food small enough to get into your cells. Main Structures stomach, esophagus, mouth, salivary glands, large and small intestines, rectum, villi

Skeletal system Functions protects organs, produces blood, stores minerals, movement and support Main structures: bones, joints, ligaments

Muscular system provide movement for the body The main function skeletal: Pull bones to cause movement smooth: Organ muscle, and vascular walls cardiac: Heart contractions Main structures: 3 types of muscle And tendons
