Anatomy & Physiology Flashcards
(15 cards)
What are the four pumping chambers of the heart?
Left atrium, left ventricle, right atrium, right ventricle
The heart consists of four chambers that play crucial roles in blood circulation.
What does the left atrium do?
Receives oxygenated blood from the lungs and pumps it into the left ventricle
The left atrium is responsible for gathering oxygen-rich blood before it is sent to the body.
What is the function of the left ventricle?
Pumps oxygenated blood to the different parts of the body
The left ventricle is more muscular than the other chambers to effectively distribute blood.
Which valve is located between the right atrium and right ventricle?
Tricuspid valve
The tricuspid valve regulates blood flow from the right atrium to the right ventricle.
What is the role of the inferior vena cava?
Drains deoxygenated blood from the lower body to the right atrium
The inferior vena cava is essential for returning blood to the heart.
What is the arch of the aorta?
The great artery arising from the left ventricle that gives rise to all other arteries
It serves as the central distribution point for arterial blood.
What are the first branches from the aortic arch?
Brachiocephalic artery, left common carotid artery
These branches supply blood to the head, neck, and arms.
What is the function of the brachiocephalic artery?
Gives rise to the right common carotid and right subclavian arteries
It is important for supplying blood to the right side of the body.
What is the thoracic aorta?
The part of the aorta that turns downward and lies on the anterior surface of the spinal column
It continues into the abdominal aorta below the diaphragm.
What does the abdominal aorta supply?
Supplies blood to the lower body and organs
It is crucial for distributing blood to the abdominal region.
True or False: The superior vena cava drains blood from the lower body.
False
The superior vena cava drains blood from the head and shoulders.
Fill in the blank: The _______ connects the right atrium to the right ventricle.
Tricuspid valve
This valve ensures proper blood flow between the two chambers.
What are potential drainage points during a partial autopsy?
Inferior vena cava, superior vena cava
These veins can be accessed for drainage during embalming.
What is the purpose of the aortic arch in embalming?
Central distribution point for embalming fluid
It is a key area for introducing embalming solutions.
What structure pumps deoxygenated blood to the lungs?
Right ventricle
The right ventricle is responsible for sending blood to the lungs for oxygenation.
