Blood and Lymphatic and Immune System

1. BLOOD AND THE
LYMPHATIC AND IMMUNE
SYSTEM
CHAPTER 6

2. BLOOD AT A GLANCE

3. FUNCTION
 Blood transport gases, nutrients and waste all areas of the body either attached to
red blood cells or dissolved in plasma. White blood cells fight infection and
disease, and platelets initiate the blood clotting.

4. ORGANS
Formed Elements :
 Erythrocytes a red blood cell that (in humans) is typically a biconcave disc without a nucleus.
Erythrocytes contain the pigment hemoglobin, which imparts the red color to blood, and transport
oxygen and carbon dioxide to and from the tissues.
 Leukocytes a colorless cell that circulates in the blood and body fluids and is involved in
counteracting foreign substances and disease; a white (blood) cell. There are several types, all
amoeboid cells with a nucleus, including lymphocytes, granulocytes, monocytes, and
macrophages.
 Platelets , also called thrombocytes (thromb- + -cyte, "blood clot cell"), are a component of blood
whose function (along with the coagulation factors) is to stop bleeding by clumping and clotting
blood vessel injuries. Platelets have no cell nucleus: they are fragments of cytoplasm that are
derived from the megakaryocytes of the bone marrow, and then enter the circulation.
 Plasma the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are
suspended.

7. THE LYMPHATIC AND IMMUNE SYSTEM
AT A GLANCE

8. FUNCTION
The lymphatic consist of a network of lymph vessels that pick up excess tissue fluid,
cleanse it, and return it to the circulatory system. It also picks up fat that have been
absorbed by the digestive system. The immune system fights disease and infection‘s
.

9. ORGANS
 Lymph Nodes each of a number of small swellings in the lymphatic system where lymph is filtered
and lymphocytes are formed.
 Lymphatic Vessels are thin walled, valved structures that carry lymph. As part of the lymphatic
system, lymph vessels are complementary to the cardiovascular system. Lymph vessels are lined by
endothelial cells, and have a thin layer of smooth muscles, and adventitia that bind the lymph
vessels to the surrounding tissue.
 Spleen an abdominal organ involved in the production and removal of blood cells in most
vertebrates and forming part of the immune system.
 Thymus Glands a lymphoid organ situated in the neck of vertebrates that produces T cells for the
immune system. The human thymus becomes much smaller at the approach of puberty.
 Tonsils either of two small masses of lymphoid tissue in the throat, one on each side of the root of
the tongue.
