What is systolic blood pressure?

Which statement explains why the ventricles contract after the atria?

Three areas involved in the control of the heart action are listed.

1. Atrioventricular Node

2. Sinoatrial Node

3. Purkyne Tissue

In which order are they involved?

Node found in the septum of the right atrium and ventricle:

Vessel that carries blood to the heart; thinner walls and thicker lumen:

Tricuspid and Mitral Valves:

Fluid that is transported within the lymphatic system; plays a role in immune response:

Stage of the cardiac cycle in which the ventricles forcefully contract to push blood out of the heart:

Fluid composed of plasma and formed elements found exclusively in blood vessels:

Vessels that carry blood away from the heart; thicker walls to withstand high pressure:

Fluid that is free floating in tissues; formed when hydrostatic pressure pushes plasma out of the capillaries:

Fibers that run along the septum and walls of the ventricles that are responsible for the contractions during ventricular systole:

Pulmonary and aortic valves:

First chambers of the heart; thinner walls that are able to produce less pressure; the first chambers to contract:

The "pacemaker" of the heart; causes the atria to contract and send a signal to the AV node:

First stage of the cardiac cycle; atria contract:

Stage of the cardiac cycle where all valves are closed and there is no pressure:

Chambers of the heart that have very thick walls to generate high amounts of pressure:
