Quiz Flashcards
What are the chambers in the heart?
Right atrium, right ventricle , left atrium and left ventricle
What are the two valves in the heart
Semilunar valve, and Atrioventricular valve
Where is the semilunar valve located?
Between a ventricle and blood vessel
What valves does the semilunar valve include?
Pulmonary(right) and aortic(left) valves
What is in the electrical system of the heart
Sinoatrical node, atrovenicular node, purkinje fibers
What is the pacemaker of the heart
The Sinoatrial Node
What is the pacemaker of the heart
The Sinoatrial Node
Which parts of the heart is deoxidized?
The right atrium and right ventricle
Which part of the heart is rich of oxygen?
The left atrium and left ventricle
How does the blood flow in the Systole?
(Heart contracts)
Blood flows into the aorta from the left ventricle, and pulmonary artery from the right ventricle.
How does blood flow in the diastole (Heart is relaxed)
blood moves from atrium to ventricles filling it up.
What’s the function of the right atrium? And what happens after the blood leaves the right ventricle?
The right atrium receives the oxygen poor blood from the body and pumps it to the right ventricle then the lungs where it becomes oxygenated
What’s the function of the left atrium? And what happens when you leave the chamber
It receives the oxygen rich blood from the lungs then pumps it to the left ventricle.
What do the lungs do for our blood?
Give them oxyfen
What is the function of the right ventricle and what happens when you leave the right ventricle?
It pumps oxygen poor blood to the lungs, and then that blood gets oxygenated
What does the left ventricle do?
Pumps oxygenated blood to the body
What is the artery’s purpose ?
Carry oxygen rich blood from your heart to your body.
What are characteristics of the artery?
Strong, muscular and thick, located deep in the muscle. Has no valves, except the pulmonary artery.
What is the veins purpose?
Collect oxygen poor blood and return it to your heart.
Where are the veins located?
All over your body.
What is the capillary?
It transports blood, nutrients, and oxygen to cells in your organs and body systems
What are some characteristics of capillary?
Thin walls, very small; are located inside all tissues, do not have muscle tissues nor valves
What is pulmonary circulation?
A network of veins, lymphatics and arteries that move blood and other tissue fluids from the heart to the lungs, then back.
What is coronary circulation ?
The circulation of bloods in arteries and veins that supply the heart muscle
