Pathway Patrol
What chamber does blood enter after the superior vena cava?
Right atrium
What are the upper receiving chambers of the heart called?
Atria
Activated by cleaving the soluble portion of the molecule, the insoluble section then preciptates into solid fiber
Firbrinogen
What does “palpate” mean?
To feel with the hands (e.g., feeling for a pulse)
which occurs first in the Hemostasis process
Vascular Spasm
What valve prevents backflow between right atrium and right ventricle?
Tricuspid valve
What arteries carry oxygen-poor blood from the heart to the lungs?
Pulmonary arteries
This term refers to white blood cell prodcution
Leukopeisis
What does “auscultate” mean?
To listen
True or False: The embolus is a stationary clot.
False – that’s a thrombus
Why does the left ventricle pump harder than the right?
It sends blood through the entire body (systemic circuit), requiring more pressure
Which valve lies between the left ventricle and the aorta?
Aortic semilunar valve
This WBC defends against parasitic worms
Eosinophil
What artery do you press for checking the pulse at the wrist?
Radial artery
What is an embolism?
An embolus that obstructs a vessel
What major artery does the left ventricle pump into?
Aorta
What structure drains deoxygenated blood from the heart muscle directly into the right atrium, along with the vena cavas?
The coronary sinus
What WBC is nicknamed “the bacteria slayer”?
Neutrophils
On an ECG, what wave represents ventricular depolarization?
QRS complex
Name a commonly prescribed or used medications that help prevent the formation of blood clots (anticoagulants).
Aspirin, Heparin, and Warfarin
What is the correct order for blood leaving the lungs?
Pulmonary veins → Left atrium → Mitral valve → Left ventricle
Which heart chamber has the thickest walls and why?
Left ventricle; it must generate high pressure to pump blood throughout the body
Name the 4 steps of hemostasis in order.
Vascular spasm, platelet plug formation, coagulation, clot retraction
Which artery is commonly auscultated when taking a manual blood pressure reading with a cuff and stethoscope?
Brachial artery
A patient with a clot blocking blood flow in the lungs is likely suffering from this condition.
Pulmonary embolism
