Homeostasis

• The ability of the body to keep a healthy, internal balance

How does your body respond when your body temperature drops below normal?

Maintaining Homeostasis

• Keeping a healthy balance involves negative feedback loops

• The goal of a negative feedback loop is to go against a change to bring the body back to its balance or set point

Multiple Choice

Passage way that moistens the air and has hairs to trap dust and particles

• Nasal cavity

• Bronchi

• Mouth cavity

• Larynx

Definition of terms:

• Respiration: a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

• Gas exchange: It  is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs.

• Diffusion: the process of a substance spreading out to evenly fill its container or environment.

Inside the lungs there are lots of little sacks called.......

Here, oxygen passes into the blood and carbon dioxide leaves the blood.

Parts of the Respiratory System

- Mouth/nose

- Nasal passages

- Pharynx

- Larynx

- Trachea (windpipe)

- Bronchi

- Lungs

- Diaphragm

Mouth and Nose

Your mouth and nose provide air passage ways for air to move in and out of your body.

Pharynx

The main job of the pharynx is to warm and moisten the air that you breathe in. The pharynx connects your mouth and nasal passages to the trachea.

Larynx

The larynx is a hollow, muscular organ that connects your mouth, nose, and pharynx to the trachea. The larynx also helps you make sounds and talk.

Multiple Choice

The mouth and nose are parts of the respiratory system

• TRUE

• FALSE

Multiple Choice

The larynx is responsible for

• breathing

• making sounds

• eating

• pumping blood

Trachea

The trachea is the tube or pipe that connects your mouth and nose to your lungs. The trachea (tray-key-ah) is made of cartilage, muscle, and membranous tissues. Near the bottom, the trachea splits into 2 smaller tubes called Bronchial tubes which connect to your lungs.

Multiple Choice

Your trachea connects your mouth to your

• stomach

• lungs

• ears

• heart

Lungs

Your lungs are the primary organs of the respiratory system. Inside your lungs are tiny blood vessels (capillaries) that allow for the exchange of oxygen and carbon dioxide. These capillaries cover tiny air sacs called Alveoli.

Breathing in

• When you breathe in, your diaphragm and rin muscles contract, pulling air into your lungs. The air travels in through your mouth or nose, down through your pharynx, larynx, and trachea to the bronchi, then into your lungs.

Breathing In

In your lungs, your blood passes through capillaries that cover small air sacs called Alveoli. The alveoli allow the carbon dioxide in your blood to escape as your red blood cells pass through the capillaries. After releasing carbon dioxide, your red blood cells replace it with oxygen to be transported to your cells.

Multiple Choice

Where does the blood coming to the lungs (deoxygenated) come from?

• Your toes

• Your heart

• Your brain

• Your arms

Multiple Choice

After releasing carbon dioxide to be breathed out and replacing it with oxygen, where does your blood go?

• back to your heart

• to your arms and legs

• to your brain

Breathing Out

When you breathe out, your rib muscles and diaphragm relax, pushing the air out of your lungs and back through your trachea to your mouth and nose. When you breathe out, you are expelling or getting rid of the carbon dioxide produced in your cells.

Multiple Choice

The respiratory system works with which other system to get oxygen to your cells?

• Muscular

• Skeletal

• Digestive

• Circulatory

Multiple Choice

When your breathe in, your diaphragm

• contracts, pulling air into your lungs

• relaxes, pulling air into your lungs

• contracts, pushing air out of your lungs

• relaxes, pushing air out of your lungs

The Circulatory System

Blood carries things like oxygen and nutrients to each cell in the body. The heart pumps blood through the body through a system of tubes called blood vessels.

The Circulatory System

Arteries are a type of blood vessel that carries oxygen-rich blood away from the heart. Veins are another type of blood vessel which carries oxygen-poor blood back to the heart.

Multiple Choice

What pumps blood through the body?

• heart

• blood vessels

• lungs

Multiple Choice

Blood vessels that carry blood away from the heart are called:

• veins

• arteries

Multiple Choice

Blood vessels that carry oxygen-poor blood back to the heart are called:

• veins

• arteries

Multiple Choice

What is the main function of the oxygen taken in through breathing?

• It moves blood throughout the body.

• It directly breaks down food in the stomach.

• It is used to make energy needed by cells to function.

• It is added to bones in the arms and legs as they grow.

Multiple Choice

Which explains how the circulatory system and respiratory system work together to sustain the human body?

• The respiratory system takes in oxygen that is carried by the circulatory system throughout the body.

• The respiratory system and circulatory system work to regulate temperature by cooling or warming the body.

• The respiratory system takes in carbon dioxide that is carried by the circulatory system to cells for respiration.

• The respiratory system and circulatory system both excrete waste to the digestive and excretory systems.
