What are the components of blood?
• Plasma is the liquid part of the blood
What makes up blood?
• Blood is made up of four components:– Plasma– Red blood cells– White blood cells – Platelets

What determines the type of blood that a person can receive in a transfusion?
• Marker molecules on your red blood cells determine your blood type and the type of blood that you can safely receive in transfusions.

What are the structures and function of the lymphatic system?
• A network of vein-like vessels that returns the fluid (lymph) to the bloodstream.
• The structures are the lymph nodes

Plasma
• The liquid part of the blood
• 90% of plasma is water• 10% of plasma is
dissolved materials such as nutrients or glucose
• Plasma is yellow

Red Blood Cell
• Take up oxygen in the lungs and deliver it to cells everywhere in the body
• They are produce only in the red bone marrow
• They do not undergo mitosis and cannot reproduce.

Hemoglobin
• An iron containing protein that bonds chemically with oxygen molecules
• Remember DNA contained the code to produce proteins
![Page 8: Chapter 16 Circulation Section 2 Blood and Lymph](https://reader035.fdocuments.in/reader035/viewer/2022081421/56816414550346895dd5c799/html5/thumbnails/8.jpg)
White Blood Cell• Are also produced in the
red bone marrow• They are the body’s
disease fighters• They capture invaders like
bacteria by engulfing them and digesting them
• They lose their lives in the battle against disease and are also known as puss

Platelet
• Platelets are cell fragments that play an important part in forming blood clots
• Because of their irregular shapes they are able to latch together and form clots

Lymphatic System
• A network of vein-like vessels that returns the fluid (lymph) to the bloodstream
![Page 11: Chapter 16 Circulation Section 2 Blood and Lymph](https://reader035.fdocuments.in/reader035/viewer/2022081421/56816414550346895dd5c799/html5/thumbnails/11.jpg)
Lymph
• Fluid inside the lymphatic system
• It consists of water and dissolved materials such as glucose
• I also contains white blood cells that have left the capillaries
![Page 12: Chapter 16 Circulation Section 2 Blood and Lymph](https://reader035.fdocuments.in/reader035/viewer/2022081421/56816414550346895dd5c799/html5/thumbnails/12.jpg)
Lymph Node
• Small knobs of tissue that filter lymph, trapping bacteria and other disease-causing microorganisms in the fluid
• When the body is fighting an infection, the lymph nodes become enlarged and can hurt
![Page 13: Chapter 16 Circulation Section 2 Blood and Lymph](https://reader035.fdocuments.in/reader035/viewer/2022081421/56816414550346895dd5c799/html5/thumbnails/13.jpg)
Blood Transfusion
• The transfer of blood from one person to another
![Page 14: Chapter 16 Circulation Section 2 Blood and Lymph](https://reader035.fdocuments.in/reader035/viewer/2022081421/56816414550346895dd5c799/html5/thumbnails/14.jpg)
Rh Factor
• Another protein in red blood cells
• It can cause a clumping reaction in blood
![Page 15: Chapter 16 Circulation Section 2 Blood and Lymph](https://reader035.fdocuments.in/reader035/viewer/2022081421/56816414550346895dd5c799/html5/thumbnails/15.jpg)
Marker Molecules
• Blood types such as A, B, AB, and O are determined by marker molecules that are on red blood cells
• These marker molecules help to identify the types of cells and their function

Why do vampires drink blood?
Are they parasites?
What might their digestive system look like?
Draw a diagram of a vampires digestive system and determine if the vampire need type A blood, type B blood, type AB blood or type O blood.
