2. Plasma (water, proteins, amino acids..etc) = 55%

91% Water

7% Blood Proteins

2% Nutrients

Fibrinogen- helps clot blood by acting as glue on top of platelets and other clotting factors.

Albumin- main protein of human plasma, regulates colloidal osmotic pressure of blood.

Globulin-participate in immune system.

Platelets are also called..

About 5,000,000 per mm^3 of blood. 

hormone produced by the liver and kidneys that allows for excess red blood cells to be produced. 

-Granulocytes (granular cytoplasm)

-Neutrophils, Eosinophils, Basophils, Agranulocytes (lacking granular cytoplasm) Monocytes, lymphocytes.

1) Lymphocytes (20-25%)

2) Monocytes (3-8%)

1) Basophils (.5-1%)

2) Neutrophils (60-70%)

3) Eosinophils (2-4%)

is dark and takes up almost whole cell; almost no cytoplasm seen

What is the process of stopping bleeding involving the coagulation and clotting of the blood to seal the site of damage called?

1) Blood vessel spasm

2) Platelet Plug Formation

3) Blood Coagulation

Delivers blood to all body cells and carries away waste.

This contains fluid for the heart to float in reducing friction. 

Between the left ventricle and the aorta.

The cusps (flaps) of the bicuspid and tricuspid valves are anchored to the ventricle walls by fibrous “cords” called _____ ________. 

1. Cardiac Output
2. Blood Volume (5 liters for avg adult)
3. Blood Viscosity
4. Peripheral Resistance

________ Is a recording of the electrical events (changes) during a cardiac cycle.

depolarization of the atria (atrial contraction-systole)

depolarization of the ventricles (ventricular contraction, systole)

Repolarization of the ventricles.

opening and closing of the valves,

flow of blood into and out of the chambers,

vibrations in muscle. 

Sudden Arrhythmia Death Syndromes or Sudden Adult Death Syndrome

The width of a single small sqaure on ECG paper represents ____ seconds.

allows exchange of materials (oxygen, nutrients) between blood and tissues. 

The narrowing of the blood vessel’s lumen is called _____

1. Contraction of the diaphragm.
2. Pumping action of the skeletal muscles.
3. Valves in the veins.

1) Ascending Aorta

2) Aortic Arch

3) Descending Aorta

4) Abdominal Aorta

These return blood from the lungs to the heart (connects to left atrium)

Right Subclavian (supplies blood to the arms) and the Left Common Carotid (bicarotid)

1. a blood clot obstructs a coronary artery, commonly called a “heart attack.”

1. deposits of fatty materials such as cholesterol form a “plaque” in the arteries which reduces blood flow.

1. Angioplasty, where a catheter is inserted into the artery and a balloon is used to stretch the walls open.

1. high blood pressure, the force within the arteries is too high. 

1. sphygmomanometer
