What do you measure heart rate by?
Beats per minute
What is the function of the right atrium?
Receives blood from the body
Identify the part

Aorta
This process is a 2 stage process in the Respiratory System
Gas exchange
What are the three components of the cardiovascular system?
Central pump (heart)
Vascular system (blood vessels)
Circulating fluid (blood)
Define Blood Pressure
The force of blood on artery walls
What is the function of the left atrium?
Receives blood from the lungs
Identify the part
Pulmonary veins
This process helps bring oxygen to the circulatory system and is the opposite of photosynthesis.
Cellular Respiration
What is the difference between systole and diastole?
Systole is when the heart is pushing/pumping and diastole is when the heart is resting
What is a closed system?
as the blood travels throughout the body, it is enclosed in various vessels of the heart the entire time (never leaks out into tissues)
What function do the heart valves serve?
They separate the chambers up and down
Name the 4 chambers of the heart.
Left atrium, right atrium, left ventricle, and right ventricle
This process constantly occurs as blood passes through the heart, arteries, capillaries, and veins.
How many oxygen molecules are in each hemoglobin molecule?
4 O2
What is the diastole phase?
When the heart is relaxed, the blood flows passively through the atria
What function do the capillaries serve?
Allow molecule exchange across their walls in and out of the blood
This part of the cardiovascular system has valves but is not an organ.
This process occurs when the heart relaxes and blood flows into both atriums.
Diastolic phase
What type of blood does the right side of the heart deal with?
Deoxygenated blood
What is the systole phase?
When blood is forced or pumped first from each atrium to the ventricle to the heart
What do veins and venules do?
Carry blood from capillaries to the heart
This substance in the cardiovascular system makes up a majority of blood but isn’t alive like the blood cells it carries.
Plasma
This process occurs when the heart contracts/ squeezes and lets blood into the ventricles and, at the same time, releases blood into the body.
Systolic phase
What does oxygenated blood return to the heart through?
Pulmonary veins arriving at the left atrium
