Cells, tissue, organs, organ systems, organism

cells, tissue, organ. organism system, organism

Analogy: A cell is like a baby its just starting out it evolves into a tissue like a baby grows to be a toddler tan into an organ like a child. Than into a teenager like an organ system and finally an adult (organism)

The Structure is brain and spinal cord and its function is that it sends signals between the brain and the body. It controls the body activities

Structure: skeletal, cardiac, and smooth muscles. Function: allows movement in the body.

Structure: stomach, liver, gall bladder, pancreas, intestine, anus, and mouth. Function: Breaks down nutrients small enough for our body to absorb for energy.

Structure: kidney, bladder, ureters, urethra. Function: removing liquid waste and filtering your blood stream.

Structure: heart vine, arteries, capillaries. Function: Delivers oxygen, nutrients, hormones, and other important things.

Structure: Lungs, nose, windpipe, and Trachea (throat) Function: Bring oxygen into your body also sends carbon dioxide out of the body.

Structure: Leukocytes, phagocytes, bone marrow, spleech, Lymph nodes Function: keeps body healthy and alive also attacks harmful substances.

Protects body by fighting off harmful substances

controls all activities of the body by sending signals between the brain and the body.

breaks down nutrients small enough for the our body to absorb as energy

removing liquid waste and filtering your bloodstream

respiratory system: bring oxygen into our bodies.

cardiovascular system: (your heart and blood vessels) supplies your body's organs with oxygen and nutrients so your organs can do their jobs.

1.Cardiovascular controls the blood circulation and sends blood to the tissue and organs.

2. The Excretory system removes toxins from the body and keeps concentration of nutrients, water stable and minerals.

3. Respiratory system controls the balance of oxygen and carbon dioxide in the body and the changing breathing rate to meet the demands of the energetic body.

4. Muscular system generates heat and causes movement.

5. Digestive system ensures that the stomachs environment has the right PH balance.

6. The nervous system maintains and regulates homeostasis.

7. Immune system protects the body by fighting harmful substances.

The excretory system filters out excess fluid, salts and toxins from your cardiovascular system (bloodstream) using kidneys and bladder.

Cardiovascular circulates blood to deliver oxygen (respiratory) and nutrients (digestive) to every part of the body.

Nervous system receives and interprets stimuli in the environment and signals muscular system to move.

Muscle tissue is also found inside of the heart, digestive organs, and blood vessels that help move substances throughout the body.

nervous system allows the immune system to engage the rest of the body in the fight against infection by sending signals
