Heart Structure
This structure separates the right and left sides of the heart
septum
How many liters of blood does the average human body contain
5 liters
This blood vessel carries blood away from the heart
artery
Give the primary function of the circulatory system
To transport nutrients and gases to different parts of the body
The most common blood type
O+
These separate each chamber
one-way valves
The liquid portion of blood
Plasma
What is the largest artery in the body called?
Aorta
The chamber before the bloods goes into the lungs
Right ventricle
On average how many times does your heart beat per day
100,000 times per day
Name the four chambers of the heart.
Left atrium, left ventricle, right atrium and right ventricle
Which blood component contains hemoglobin and what is its main role
Red blood cells, they transport oxygen and carbon dioxide via hemoglobin.
This blood vessels brings blood back to visit the heart
Veins
The two gases that are exchanged in the lungs
Oxygen and carbon dioxide
The least common blood type
AB-
This chamber sends oxygen-rich blood into the aorta
left ventricle
Name the blood cells (or fragments) that help repair damaged blood vessels and form clots
Platelets
What are the tiny vessels that connect arteries to veins and allow exchange of materials
Capillaries
The first chamber to receive oxygen-rich blood from the lungs
Left atrium
the weight of an average human heart
9-12 ounces
Explain why the heart must have one-way valves
Valves prevent backflow, ensuring blood moves in a single direction through heart chambers and into arteries; this maintains efficient circulation
Where platelets, red blood cells, and white blood cells are produced
Bone marrow
Approximately how many miles would your blood vessels stretch if laid end-to-end
60,000 miles
Explain one other function of blood/circulatory system beyond transporting nutrients and gases.
To collect waste and transport to kidneys, lungs, and skin; help carry hormones and immune cells (e.g., white blood cells) to fight infection and regulate body systems.
The universal recipient
AB+
