Blood, lymphatic and Immune Systems

Question 1

is the study of the blood and blood-forming tissues and the diseases associated with these tissue

Answer 1

Hematology

Question 2

Physicians who specialize in the study and treatment of blood and blood disorders

Answer 2

hematologist

Question 3

Hematologists:
-Hematologists treat malignant (cancerous) and nonmalignant blood diseases
-first to use chemical therapies (chemotherapy) to treat hematological malignancies.
-discovered that these treatments could also be effective on the so-called solid tumors, such as breast, lung, and stomach cancers (previously treated only with surgery).hematology became closely associated with the medical specialty of oncology (cancer treatment)

Answer 3

Hematologists

Question 4

Blood
-major function of blood is to transport oxygen and nutrients to the cells of the body and remove carbon dioxide and metabolic waste products from the cells
-The two main components of blood are plasma and formed elements, such as erythrocytes (red blood cells [RBCs]), leukocytes (white blood cells [WBCs]), and platelets (clotting cells).

Answer 4

Functions of Blood

Question 5

Erythrocytes deliver oxygen to the body tissues via the circulatory system

Answer 5

Job of the red blood cells erythrocytes

Question 6

Leukocytes provide a line of defense against pathogens

Answer 6

job of white blood cells leukocytes

Question 7

Platelets have a clotting ability that prevents excessive loss of blood.

Answer 7

the function of platelets

Question 8

Erythrocytes, leukocytes, and platelets are produced in the bone marrow by a process called hematopoiesis.

Answer 8

hematopoisesis- the process by which white blood cells, red blood cells and platelets are produced in bone marrow

Question 9

-lymph
-lymph vessels
-lymph nodes,
-three organs: the tonsils, thymus, and spleen

Answer 9

The lymphatic system

Question 10

The lymph circulating through the lymphatic system comes from the blood. It contains WBCs (leukocytes) responsible for immunity, monocytes, and lymphocytes

Answer 10

the role of White blood cells in the lymphatic system

Question 11

Answer 11

Immunology

Question 12

Anything that causes and immune response

Answer 12

antigen

Question 13

Types of antigens

Answer 13

harmless grass pollen, or harmful, such as the flu virus.

Question 14

pathogens

Answer 14

Disease-causing antigens such as the flu virus

Question 15

The body’s ability to fight disease and protect itself depends on an adequately functioning

Answer 15

immune response

Question 16

medical specialist who studies and treats the body’s defense mechanism against invasion of foreign substances that cause disease also aids when the immune system breaks down and the body loses its ability to recognize antigens or its ability to mount an attack against them

Answer 16

immunologist

Question 17

When the immune system to reacts in a manner disadvantageous to the body by way of allergic or autoimmune diseases

Answer 17

autoimmune diseases

Question 18

-acquired immune deficiency syndrome (AIDS), which is caused by the human immunodeficiency virus (HIV);
-immune complex diseases, such as malaria and viral hepatitis; -
-autoimmune diseases, such as lupus; transplanted cells and organs; allergies; and various cancer types related to the immune system.

Answer 18

immunodifficiency diseases

excision of an embolus, either surgically or with enzymes that dissolve the clot

Question 22

leuk/emia
leuk/o: white
-emia: blood condition

Answer 22

Answer 24

pathogen

Question 25
