The Heart
_____ brings blood to the heart and ____ carries it away
veins, arteries
Breathing starts with the ________ and ______
mouth and nose
breaks down food into nutrients to be absorbed into the bloodstream and waste
digestive system
What is the wall that separates the left and right side of the heart
septum
Where does cellular respiration take place
mitochondria
Where are ventricles located
on the bottom chambers
trachea
responsible for getting oxygen into your blood and removing carbon dioxide.
respiratory system
what is the job of white blood cells
fight disease
small intestine
The right side of your heart pumps blood to the ____ and the left side pumps to the _____
lungs
body
What are the two large branches called
bronchus
transport oxygen, carbon dioxide, and nutrients throughout the body
cardiovascular system
What two gases are exchanged in the alveoli
O2 and CO2
what is the correct sequence for the path of blood through the body
Heart → lungs → heart → other body parts
Oxygen poor blood enters the heart through the _____
right atrium
What are the tiny tubes called that have small sacs at the end
Bronchioles
How do the circulatory and reparatory system work together
circulatory system pumps blood and the respiratory system gets oxygen into the blood
What happens in the capillaries
nutrients are exchanged between body cells/tissue/organs
Explain the process of breathing
air in, diaphragm down, lungs expand, bronchus, bronchioles, alveoli, co2 and o2 are exchanged, breathe out co2
The ____ artery is often associated with heart attacks and supplies the heart with its own blood
coronary
When you breathe in, your diaphragm goes _______ and there is _________ pressure and ________ volume
down, less, more
What is cellular respiration and what are the two starting things of the cellular respiration formula
Glucose + oxygen → carbon dioxide + water + energy
the process by which cells break down food molecules (like glucose) and convert them into usable chemical energy in the form of adenosine triphosphate (ATP)
they provide the cells in the body with what it needs- nutrients or o2
Why is iron important to red blood cells
It it carried on hemoglobin and makes your red blood cells stronger because it's connected to carrying oxygen...without it, your heart needs to work harder to pump oxygen around the body
