clotting mechanisms
What is the function of platlets?
thrombocytes
cells that play a key role in clotting, called platelets
hemoglobin

Hemo-
Prefix meaning blood
-globin
Suffix meaning protein
epithelial, connective and smooth muscle
What three tissues are the blood vessels made from?
Arteries
These carry blood away from the heart, have thicker and stronger walls, have the highest BP
Veins
These carry blood to the heart, have lower BP and possess periodic valves to prevent back flow.
Capillaries
These are one layer thick epithelium, have diffusion and exchange potential, are the functional unit of the system.
arteries, arterioles, arterial capillaries, venous capillaries, venuoles, veins
list the blood vessels and where the blood travels away from the heart and back to the heart
epithelial, connective, cardiac muscle
What are the tissue of the heart
heart
a muscular pump made up of cardiac muscle

Right atrium
This part of the heart receives blood from the body
Left Atrium
This part of the heart receives blood from the lungs
Right ventricle
This part of the heart pumps blood to the lungs
Left Ventricle
This part of the heart pumps blood to the body
epithelial
The Endocardium, the inner most layer of the heart, made up of what type of tissue?
Endocardium, Myocardium, epicardium, pericardium
What are the four tissue layers of the heart (from the innermost to the outermost)?
Endocardium
This layer of the heart is the inner covering, continuous with lining of blood vessels.
Myocardium
This layer of the heart is the heart's muscle, cardiac muscle, and is highly vascular
Epicardium
This layer of the heart is vascular serous membrane
Pericardium
This layer of the heart is made up of two layers, the outer layer is tough fibrous cconnective tissue, the inner double layer is with serous fluid between keeps lubrication and prevents friction.

Spleen
This organ destroys old blood cells and pathogens. Has a substantial blood flow
Thymus gland
This organ receive immature T Cells, matures then, inactive with age.
Bone marrow
This organ produces lymphocytes, mature B Cells
Lymph nodes
This organ is the only place where lypmh is filtered
Lymphocytes
White blood cells that hang out in the lymph syste and fight off pathogens.
