Can anyone explain meabout the tidal volume calculations ?

 

[shinnyyy]

Can somebody please help me with valves? I know that:

• tricuspid has 3 valves and is on the right side
• bicuspid has 2 valves and is on the left side
• bicuspid is also called the mitral valve (is this true? Please confirm.)

So the tricuspid and bicuspid valves are ATRI-VENTRICULAR valves. What and where are the SEMILUNAR VALVES?? Please help !!

yup that's true
they are Atrio ventricular valves .. Semi lunar valves are found in most veins and also within the aorta ( aortic valve) & pulmonary artery ( pulmonary valve)

My sir told me that it's not in our syllabus now but there are some formulas you may know like
Minute Vol= Tidal Vol * no of Breaths per min ....
can you post the question I'll see where I can help
