Respiratory System Circulatory System Cardio- vascular System BloodCells
This muscle pulls and pushes on your lungs in order for you to inhale and exhale.
diaphragm
Where the wind pipe splits to the two lungs.
bronchi or right bronchus & left bronchus
The three purposes of the bronchioles
filter air, moisturize air, and regulate air temperature
This is where oxygen is absorbed into the blood.
alveolus or alveoli
The act of inhaling oxygen and exhaling carbon dioxide.
pulmonary respiration
The circulatory system consists of these two systems.
cardiovascular system & lymphatic system
The circulatory system carries this from the small intestine to all the cells of your body.
digested food or nutrients
The alveoli in your lungs absorb this and your circulatory system carries it to every cell in your body.
oxygen
Your cells release this and your circulatory system carries it to your lungs for disposal.
carbon dioxide
What two forces must your heart overcome in order to circulate blood to every cell in your body?
Gravity (your head needs blood) Friction (vessels are like water slides)
The three main parts of the cardiovascular system.
the heart blood blood vessels This is an x-ray of a heart
These blood vessels carry oxygen-rich blood from the heart to the entire body.
Arteries (squirt squirt)
These blood vessels send blood carrying carbon dioxide from the body to the heart which pumps the blood to the lungs for disposal.
veins
These tiny blood vessels connect arteries to cells and cells to veins.
capillaries (they kind of look like little plant roots)
This side of the heart pumps oxygen-rich blood to the body while the other side pumps carbon dioxide-rich blood to the lungs.
Right side carbon dioxide- rich blood Left side oxygen-rich blood
These cells carry oxygen, nutrients and waste throughout the body
red blood cells
This is the liquid in which your blood cells live.
plasma (it makes up over half of your blood volume)
These help patch up broken blood vessels by clotting.
platelets
These blood cells patrol your body in order to capture and kill invaders like viruses and bacteria.
white blood cells (they like to hang out in your spleen when there’s not much to do) spleen
This is where your blood cells are produced.
bone marrow
What do cells need in order to make energy?
nutrients & oxygen
How does the circulatory system serve the body’s cells?
The circulatory system delivers oxygen and nutrients while removing waste like CO 2
Our body contains many specialized cells which group together with their own kind to form this.
tissue
Cells are made up of these.
organelles
This is the process of cells receiving oxygen to make energy and releasing carbon dioxide waste.
