Week 8: Circulatory System

Provides communication between widely separated body parts through transportation of hormones, nutrients, wastes, respiratory gases, vitamins, minerals, enzymes, water, leucocytes, and antibodies.

transporting medium

2 components of blood

Plasma is the   part of the blood

Plasmis composted of   water, ions, and proteins in the form of   and  

RBC aka  

WBC aka  

Blood Platelets aka  

shape of RBC

RBC is formed in the   (in the sternum, ribs, iliac crest, clavicle, scapulae, and skull)

the principal component of RBC is  

Oxygen:  
Carbon Dioxide:  

Life span of RBC is   days

Older, deteriorated RBC are removed by the   cells of the liver, spleen, and bone marrow, and replaced daily

heme in the blood is converted to   (part of the bile)

2 types of Leucocyte or WBC

Originates in the bone marrow and consists of Neutrophil, Basophil, and Eosinophil

Originates in bone marrow and lymphatic tissue and consists of Monocyte and Lymphocyte

3 types of Granulocytes or polymorph

2 types of Agranulocytes or mononuclear

Identify the main target of the Leucocyte:

Bacteria and Fungi

Identify the main target of the Leucocyte:

Anti-inflammatory response

Identify the main target of the Leucocyte:

Parasitic infections

Identify the main target of the Leucocyte:

destruction of pathogens

Identify the main target of the Leucocyte:

triggering a specific immune response

Anucleate (no nucleus) cellular fragments associated with hemostasis (blood coagulation)

Thrombocytes originate from the fragmentation of   in bone marrow

Blood Platelets function in   ( )

Names Indicate type of   present on the  

The plasma normally contains no   against   present on its own RBC

special proteins that fight off and destroy disease-causing germs

foreign substance introduced into the body and causes immune response; molecules produced by the body.

• Type AB –  
• Type O –  

Heart is a highly muscular pumping organ located in the   enclosed by a  

Tubes on varying diameters through which blood passes

 Carries oxygenated blood
 Away from the heart

 Carries deoxygenated blood
 Toward the heart

 Gas exchange
 joins Arteries and Veins

Circulation if the blood flow through the  

3 types of circulation

It is the blood flow from the left ventricle into the aorta, other arteries, arterioles, capillaries, venules and veins to the right atrium of the heart

It is the blood flow from the right ventricle to the pulmonary artery to lung arterioles, capillaries and venules, and veins, to left atrium of the heart

4 Chambers of the heart

wall between the chambers of the heart

- prevents the backflow
- Separates the chamber of the blood

largest artery in the human body

powerful contraction from the lower chambers

- blood flow from the capillaries, venules, and veins of stomach, intestines, spleen, pancreas, and gall bladder into portal veins, liver sinusoids to hepatic veins, into inferior vena cava, to right atrium of the heart.

Hepatic-portal Circulation is the blood flow from the capillaries, venules, and veins of stomach, intestines, spleen, pancreas, and gall bladder into portal veins, liver sinusoids to hepatic veins, into  , to   of the heart.

Alternate expansion and elastic recoil of blood vessels caused by intermittent ejections of blood from heart into aorta with each ventricular contraction

Pulse can be felt because of   of arterial wall
