What are the four chambers of the heart?
1. Right Atrium
2. Right Ventricle
3. Left Atrium
4. Left Ventricle
What are arteries?
Blood vessels that carry OXYGENATED blood AWAY from the heart.
What heart did we dissect during the Heart Dissection lab?
Pig's Heart
What heart disease did the man have in the Body Story video?
Heart Attack
What are the four blood groups?
1. A
2. B
3. AB
4. O
Where does blood enter the heart? Where does it exit the heart?
Enters: Superior and Inferior Vena Cavas (SVC & IVC)
Exits: Aorta
What are veins?
Blood Vessels that carry DEOXYGENATED blood TOWARDS the heart.
What chamber of the heart is the biggest?
Left Ventricle because it pumps blood out into the rest of the body and it needs to withstand the extra force.
Which component of blood is non-living?
Plasma
What is the universal donor for blood? Universal receiver?
Universal Donor: O-
Universal Receiver: AB+
How many pulmonary arteries are in the heart? How many pulmonary veins?
Pulmonary Arteries: 2
Pulmonary Veins: 4
What is the LARGEST Artery?
Aorta
What are the walls between chambers called?
Septum
Which side of the heart carries DEOXYGENATED blood?(HINT: Think of the atrium and ventricle that carries deoxygenated blood)
Right side
What are antigens and antibodies?
Antigens: Uniquely shaped identifying markers on the surface of a blood cell
Antibodies: Proteins produced by white blood cells that counteract foreign antigens
What are the four valves of the heart?
1. Tricuspid Valve
2. Pulmonary Valve
3. Mitral (Bicuspid) Valve
4. Aortic Valve
What is the LARGEST Vein?
Inferior Vena Cava
What are the purpose of valves?
To prevent the backwards flow of blood. They open and shut with each "beat" of the heart to allow blood to pass through each chamber.
What is the main difference between the circulatory system of a fish and a human?
Fish only have one atrium and ventricle.
Fish also have a single-loop circulatory system while humans have a double-loop.
What are the four things that make up blood? What is the function of each?
1. Red Blood Cells - delivers oxygen to body and carries carbon dioxide to the heart
2. White Blood Cells - defends the body against bacteria, viruses, parasites, etc.
3. Platelets - Helps clot blood and stop bleeding. Helps form scabs
4. Plasma - Help move blood cells place to place (liquid portion of blood)
Name all 13 parts of the heart that are involved with the blood flow in the heart (including valves... excluding lungs)
SVC, IVC, Right Atrium, Tricuspid, Right Ventricle, Pulmonary Valve, Pulmonary Artery, Pulmonary Veins, Left Atrium, Bicuspid, Left Ventricle, Aortic Valve, Aorta
What are capillaries?
Microscopic blood vessels that connect arteries and veins together. Oxygen and waste exchange also occur in the capillaries.
Where is the coronary artery located on the heart?
Along the front middle of the heart, branching off the aorta.
What is the purpose of the Circulatory System?
- Deliver nutrients and oxygen to the body cells.
- Removes carbon dioxide and other waste from cells.
