Produce hormones involved with female reproductive development

Regulates blood sugar levels by producing insulin

Regulates calcium levels in the blood

Secretes hormones that affect other glands and organs. Also affects growth.

Produce hormones involved with male reproductive development

Regulates the immune system t help the body fight disease

Affects the rate at which you use energy

The system of the body responsible for ridding the body of unwanted waste products.

Excrete water, urea and salts in the form of urine.

Excrete carbon dioxide as well as small amounts of heat and water

Excretes most of the waste heat from the body as well as small amounts of water, salts and urea in the form of perspiration.

The fluid part of blood that contains the red blood cells, white blood cells and platelets.

Help with blood clotting

Carry oxygen to your cells, contain hemoglobin and are made in the bone marrow.

Blood vessels that carry blood from the body back to the heart.

These blood cells destroy pathogens and help clean wounds.

A collection of organs that break down food so that it can be used by the body

A series of tubelike organs that are joined end to end. These are the organs the food you eat passes through. It is part of the digestive system.

Larger pieces of food are broken down into smaller pieces by chewing or muscle action. Also called physical digestion

Where digestion begins. Both mechanical and chemical digestion take place here.

The part of food our bodies need. Carbohydrates, proteins and fats.

Air sacs in the lungs, surrounded by capillaries where the exchange of oxygen and carbon dioxide takes place.

Inhaling oxygen and exhaling carbon dioxide

Waste gas produced by cells and exhaled through the lungs.

A dome shaped musclethat contracts and relaxes to allow inhaling and exhaling

Main organs of the respiratory system that bring in oxygen and excrete carbon dioxide

The gas brought into the lungs for the body's use.

The use of oxygen by the cells to produce energy

The system of the body responsible for bringing in oxygen and getting rid of carbon dioxide.

The system of the body responsible for ridding the body of unwanted waste products.

How many kidneys does the body have?

Blood is pumped into the kidneys where it is filtered is an example of which two systems working together?

Allows movement in all directions. Located in your hip and shoulder.

Bones are fused together. Does not allow movement.

Allows movement in one direction.

Muscle action that is NOT under your conscious control

The point where 2 or more bones meet.

Connects the bones of the skeletal system

Made of tissues that relax and contract to produce movement

Allows side to side and up and down movement. Ex. neck

Muscle that is attached to the bones

Protects organs, stores minerals and fat, aids in movement, makes blood cells and provides support for the body.

Also called a gliding joint. Allows bones to glide over one another. Ex. wrist
