Let's get this started my dudes!

Something basic

What is the order of the flow of blood throughout the heart?

[ZGMFX10AFreedom]

answer

Superior and Inferior Vena Cava -> Right Atrium -> Tricuspid Valve -> Right Ventricle -> Pulmonary Valve -> Lungs -> Pulmonary Veins -> Left Atrium -> Mitral Valve -> Left Ventricle-> Aortic Valve -> Aorta -> Rest of Body

Started from a little before and a little after the heart if that is ok

You forgot to include pulmonary arteries but the rest is fine. Next time, try to use the hide function to hide your answer; instructions to use 'hide' can be found in other forums.

You could also include the pulmonary trunk before pulmonary arteries and after pulmonary valve but besides the pulmonary arteries you are correct. Your turn!

Okay my turn to ask a question:

Define nitrogenous waste.

[linzhiyan]

I think this is right

Nitrogenous waste- metabolic waste that contains nitrogen.

What is the main function of the spleen?

Answer?

The main function of the spleen is to filter the blood by getting rid of any damaged or old red blood cells.

Yep, your turn.

(heh only studied a bit of cardiovascular so far so thats pretty much all I'm going to ask)

Question:

1. List all of the major intervals of an EKG and the normal length for each one.
2. Describe what is going on during each of the intervals.
3. Identify the disorder in the EKG strip below. What causes this?

(heh only studied a bit of cardiovascular so far so thats pretty much all I'm going to ask)

Question:

1. List all of the major intervals of an EKG and the normal length for each one.
2. Describe what is going on during each of the intervals.
3. Identify the disorder in the EKG strip below. What causes this?

Answer

1. RR interval: 0.6-1.2 seconds
P wave: 80 milliseconds
PR interval: 120-200 milliseconds
PR segment: 50-120 milliseconds
QRS complex: 80-100 milliseconds
ST segment: 80-120 milliseconds
T wave: 160 milliseconds
ST interval: 320 milliseconds
QT interval: 420 milliseconds or less if heart rate is 60 beats per minute (bpm)

2. P wave is atrial depolarization, QRS complex is ventricular depolarization and atrial repolarization, T wave is ventricular repolarization

3. Ventricular arrhythmia, sometimes caused by cardiomyopathy

That is correct. Your turn!

List all blood clotting factors from I to XIII and say which factor is no longer used and why.

[MaanMaan]

Oof I've heard of 13 factors so here goes

Factor I - fibrinogen
Factor II - prothrombin
Factor III - tissue thromboplastin
Factor IV -Calcium Ion
Factor V - labile factor or proaccelerin
Factor VI - unassigned
Factor VII - stable factor or proconvertin
Factor VIII - antihemophilic factor
Factor IX - plasma thromboplastin component, Christmas factor
Factor X - Stuart-Prower factor
Factor XI - plasma thromboplastin antecedent
Factor XII - Hageman factor
Factor XIII - fibrin-stabilizing factor

Aren't they all used lmao?

Next time use the hide, spoiler, or answer function to cover up the answers so others can follow along without having the answers spoiled to them.

Alright:

My Turn:

Where is the Thymus Found? Specific Location
