What is a system?

a set of connected things or parts

forming a complex whole, in

particular.

How does this definition relate to our body

systems?

Today I am learning

about the body

systems because they

keep me alive by

working together.

Structures, Functions, and Interactions

Structures: bones, cartilage, joints, marrow

Functions: provides shape and support,

enables you to move, protects your

internal organs

Interactions:

* bones make your red blood cells

(cardiovascular/circulatory)

* helps you move (muscular)

Structures: skeletal muscle, smooth muscle,

and cardiac muscle

Functions: Involuntary muscles for breathing

and digesting food; Voluntary muscles are

under your control (movement)

Interactions: All systems b/c all of your

organs are made of muscle

Structures: Mouth, esophagus, liver, stomach,

gallbladder, pancreas, large intestines, small

intestines, rectum

Function: breaks down food into molecules the

body can use, and eliminates waste

Interactions: Uses the circulatory system to take

food to the individual cells, forms the end of the

excretory system to expel solid waste.

Structures: brain, spinal column,

nerves.

Functions: sends electrical messages to

detect & interpret info from inside and

outside the body; control center

Interactions: Tells muscles to contract

(voluntary), tells heart to pump

(involuntary)

Organs: glands such as hypothalamus,

thyroid, ovaries, testes

Functions: Controls body functions by

using chemical messages from glands

Interactions: Sends growth hormones to

skeletal system, releases adrenaline into

the blood stream to stimulate the muscles

into action.

Organs: Tonsil, Spleen, Thymus, Lymph

Nodes

Function: returns leaked fluids to blood

vessels and helps get rid of bacteria and

viruses.

Interactions: White blood cells made in the

bones grow into T cells in the thymus.

Organs: Skin, Hair, Nails

Functions: Protects; keeps water in &

foreign particles out; allows you touch;

regulates temperature; gets rid of wastes

Interactions: Works with the nervous

system to keep you aware of your

surroundings.

Structures: Large Intestines, rectum, anus

Functions: Material that cannot be

absorbed into the blood stream is

compacted in the large intestines for

elimination.

Interactions: The large intestine absorbs

water into the cardiovascular system for

use throughout the body.

Structures: kidney, urinary bladder, urethra

Functions: Blood is filtered through the

kidneys to remove cell/body waste.

Waste is stored in the bladder and

eliminated as urine.

Interactions: Cleans waste from the

circulatory system.

Structures: Nose, Trachea (Wind Pipe),

Lungs: Bronchi/Bronchioles, Alveoli

Function: Moves oxygen into the body

and removes carbon dioxide and water

vapor from the body.

Interactions: Circulatory system carries

oxygen to the cells and carbon dioxide

away.

Structures: Heart, blood vessels

Functions: Heart pumps blood through all

blood vessels.

Interactions: Highway system of the body,

carries food (digestive) and oxygen

(respiratory) to the cells and carries waste

away.

Structures: Testes, ovaries, and uterus

Function: Create a new living individual

Interactions: The endocrine system

regulates the hormones necessary for

sexual maturity and reproduction.

Match the system to its function:Digestive, Endocrine, Nervous, Muscular, Skeletal

System Function:

Glands to secrete hormones/adrenaline, etc.

Enable movement

Give shape and support; protect inner organs

Break down food for nutrients

Send electrical messages; Control center

Endocrine

Muscular

Skeletal

Digestive

Nervous

Which systems are responsible for

removing wastes from the body?

A. Urinary, digestive and excretoryB. Urinary, muscular, skeletalC. Urinary, nervous, endocrineD. Urinary, lymphatic, nervous

Describe a scenario in which your body

has to use multiple systems… then name

each of the systems used.
