3.1 -- Blood Flashcards
What is the role of the cardiovascular system?
Get blood to the tissues
The most important function of the circulatory system is the bulk transport of what three things to all the tissues of the body?
Electrolytes, gases, and nutrients
The body is too big for diffusion, meaning it must have a what-circuit pump system?
Closed-circuit pump system
What two things does the cardiovascular system regulate?
Hormonal and temperature
What three respiratory things does the cardiovascular system transport?
Respiratory gases, nutrients, and wastes
What three things does the cardiovascular system protect?
Clotting, healing, and immunity
The average adult volume is about how many liters?
3, 4, 5, or 6
5 liters
What blood is leaving the heart, is bright red, and oxygenated except for blood going to the lungs?
Arterial blood
What blood is entering the heart, is dark red, and deoxygenated except for blood coming from the lungs?
