"which describes the blood flow from chest compressions compared to normal cardiac output"
lys-0071 [83]

<span>Chest compression can save the lives of patient in cardiac arrest as it generate a small but critical amount of blood flow to the heart and brain. It provides oxygen quickly to the brain, heart, lungs and other organs until normal function of the heart and lung restored. When the patient is unresponsive without definite pulse or normal breathing then the responder should assume that the patient is in cardiac arrest. CPR or chest compression is used to keep oxygen circulating around the body until a defibrillator can be used or until the ambulance arrives. Moreover, defibrillator is a device used to help blood flow in order to help the patient survive or recover from cardiac arrest. This procedure can momentarily stops the heart and the chaotic rhythm and often allows the normal heart rhythm to resume. However, chest compression be given when the patient has no pulse while CPR is performed when the patient is unresponsive, not breathing and has no pulse.</span>

B)Differentiate between conditioned and simple reflex actions.(4points)<br>​
igomit [66]

Answer:

Explanation:

Reflex action are actions done with any predetermined or prior thought about them. They are those actions that are not within the control of ones will. Reflex actions are those actions that one cannot exercise any single form of control over. Reflex actions are controlled by the spinal cord, not by the brain.

Examples of reflex actions are:

1. Blinking of the eye.

2. Heartbeat

3. Withdrawing of your hands when put in a fire.

4. Jumping off when mistakenly step on a nail.

Reflex actions are autonomic and do not involve the brain. They are in-born and we do not have to learn the, unlike conditional reflex actions.

On the other hand, A conditional reflex action is a type of reflex action that is learned overtime and have become part of the body. In other words, conditioned reflex actions are those actions that we learn how to do them, and have gotten accustomed to them to the extent that we can now do them without thinking of them. That is, we have conditioned our body to such actions. They are not in-born like reflex actions; rather, they are learned, but have become part of us.

Examples of Conditional reflex actions are:

1. Driving

2. Looking left and right before crossing the road.

These actions are not genetically inherent in organisms, but they are done without prior thinking. They are conditioned reflex actions.
