Let's get this started my dudes!
What is the order of the flow of blood throughout the heart?
What is the order of the flow of blood throughout the heart?
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
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.ZGMFX10AFreedom wrote:Started from a little before and a little after the heart if that is okSuperior 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

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

Define nitrogenous waste.
Nitrogenous waste- metabolic waste that contains nitrogen.

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

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?

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
