This is our largest organ of protection; it consists of an outer layer of epidermis made of epithelial tissue.

What is skin?

100

The pancreas, liver, stomach and intestines are organs of this organ system.

What is the digestive system?

100

This important cell structure provides the boundary between the inner cell contents and cell's outside environment.

What is the plasma membrane?

100

The essential functions of this tissue type are movement and heat production.

What is muscle tissue?

100

Of positive or negative, the body uses this type of feedback loop to maintain homeostasis.

What is negative feedback loop?

200

This organ of the cardiovascular system is mostly muscle tissue, but also contains connective tissue within its valves.

What is the heart?

200

The trachea, bronchi, and lungs are structures of this organ system.

What is the respiratory system?

These organelles look like tiny dots in the image we studied. They are the site where amino acids are strung together to begin protein synthesis.

What are ribosomes?

200

This tissue type consist of cells called neurons that are specialized for sending and receiving messages in the form of electrical signals. 

What is nerve tissue?

200

This nervous system organ acts as the control center in most of the body's homeostatic feedback loops.

What is the brain?

300

This organ produces acid and mucus, two key substances in the digestive process. 

What is the stomach?

300

The I in MR CLIDE RUNS stands for this system, which has the skin as its largest organ.

What is the integumentary system?

300

These organelles are the site of ATP production, which is the energy molecule that powers cellular processes.

What are the mitochondria?

300

Of the four tissue types, this one is the most abundant and the most diverse.

What is connective tissue?

300

Along with the skeletal system, this organ system is responsible for the shivering that may occur when the body is regulating its temperature. 

What is the muscular system?

400

These female reproductive system organs produce hormones and ova, which are the eggs that if fertilized by sperm produce offspring.

What are the ovaries?

400

This organ system includes the tonsils and spleen, and is a big reason for the body's ability to fight infection and disease.

What is the lymphatic system?

400

When the cell needs to destroy things that are not needed (or are recognized as foreign), these organelles are responsible.

What are lysosomes?

400

Blood, bone, ligaments, and adipose (fat) are all under the category of this tissue type.

What is connective tissue?

400

Of positive or negative, the body uses this type of feedback loop to amplify a response, for example the uterine contractions that occur during childbirth.

What is positive feedback loop?

500

This structure of the respiratory system is commonly known as the voice box.

What is the larynx?

500

The cardiovascular system circulates blood, but this organ system is where blood cells are produced.

What is the skeletal system?

500

Sometimes called the post office of the cell, this organelle packages proteins into membrane-bound vesicles to prepare them to stay or leave the cell.

What is the Golgi complex?

500

Of the four tissue types, this is the one that all glands are comprised of.

What is epithelial tissue?

500

When the body is regulating its blood sugar levels, the hormone insulin is a key player.  Hormones are the chemical messengers of which organ system?

What is the endocrine system?
