Question

On unlined paper, draw a flow chart or similar map that traces the blood flow through the circulatory system.   Use the vessels from your circulation lab and heart lab. You should include the chambers of the heart and all of the vessels on your lists. Use arrows to indicate the direction of blood flow. Use two different colored pens or pencils to indication oxygenated vs. deoxygenated blood. Label all the vessels and be sure to include an a. for artery and a v. for vein following the name of the vessel.

Answer 1

Circulatory System

It is a system of complex series of tubes that transports nutrient-rich blood and waste products throughout the entire body . It consists of approximately 78 percent water. Red cells, white cells and platelets are made in the marrow of bones.

Main components of human blood are-:

1.     Plasma- This is the watery portion of the blood. Blood cells are suspended here.

2.     Red Blood Cells (Erythrocytes) Using hemoglobin, these cells carry oxygen from the lungs throughout the entire body.

3.     White Blood Cells (Leukocytes) These cells aid the immune response. They help fight off infections by engulfing and destroying foreign invaders.

4.     Platelets (Thrombocytes) Helps the blood clot. ABO Blood Grouping System: Blood is grouped based on the inherited properties of the red blood cells.

Blood Vessels and its parts

1. Arteries- Semi-elastic vessels that transport blood away from the heart.

2. Veins- Elastic vessels that transport blood to the heart.

3. Capillaries- Vessels are located within the tissues of the body that transport blood from the arteries to the veins. They are the connectors of the blood pathway.

4. Intercellular Fluid is the fluid found between the cells & tissues. This medium provides for the exchange of materials between the cells and tissues.

5. Lymph is a yellowish fluid that is found within the vessels of lymphatic system. Lymph fluid carries white blood cells of throughout the blood.

The Heart and its chambers

1. The Heart is made of cardiac muscle and is surrounded by pericardium.

2. It is composed of 4 chambers. The 2 upper chambers (atria) receive blood and the lower 2 chambers (ventricles) pump blood out. Heart valve are located between the chambers, and they prevent the back flow of blood. The septum separates the heart into 2 sides (right and left). The hearts functions as a double pump.

3. Circulation of Blood through the Body: Pulmonary Circulation - The movement of blood between the heart and lungs.

4. Systemic Circulation - The movement of blood between the heart and the rest of the body, excluding the lungs.
