Albumin
Globulins
Fibrinogen
If a person loses too much blood or plasma as a result of an injury or a burn, the body’s blood pressure may fall to critical low, causing a condition known as:
Circulatory shock
What is a master of design for doing its job of carrying oxygen?
Red blood cell, or erythrocyte
The cytoplasm of red blood cells contains _____________, a special iron containing blood protein which binds easily to oxygen and gives its characteristics red color.
Hemoglobin
What is a disorder resulting from too little oxygen being transported to body cells?
Anemia
A unique disease of the erythrocytes is____________, a genetic disease caused by a genetic defect in the hemoglobin molecules that causes them to clump together into elongated crystals under certain conditions.
Sickle-cell anemia
Surplus red blood cells are stored in the __________ until they are needed.
Spleen
What is a hand-sized organ located in the abdominal cavity behind the stomach, and supplies the body with stored red blood cells whenever it needs extra oxygen-carriers, such as during exercise or when moving from sea level to the mountains?
Spleen
The blood contains several kinds of ____________, which are produced in the bone marrow and the lymph nodes.
White blood cells, or leukocytes
What is a form of cancer in which white blood cells are produced in uncontrollable numbers?
Leukemia
The job of patrolling your 60,000 miles of blood vessels for leaks belongs to your _______, tiny disk-shaped cell fragments produced in the bone marrow that serve as roving patch kits.
Platelets
In large blood vessels or in areas of more extensive damage, a process known as ______, is used to seal the break.
Clotting
If the blood clot is on the surface of the skin, a ________ develops, and healing begins along the perimeter of the wound.
Scab
An inherited disease called __________ results in the inability to form blood clots.
Hemophilia
The heart, the blood vessels, and the blood they contain all make up the:
Cardiovascular system
Red blood cells contain “identification tags;” these tags are referred to as ___________ because they trigger the immune system to attack the red blood cells when the wrong types of blood are mixed, causing the cells to clump together or agglutinate.
Antigens or agglutinogens
Anyone can receive what type of blood because its red blood cells have neither A nor B “tags” to alarm the recipient’s immune system?
Type O blood
People with type O blood are sometimes called _________ because they can donate to people of any blood type.
Universal donors
What blood type individual can receive any type of blood because neither of these “tags” alarm his immune system?
Type AB blood
People with type AB blood are sometimes called ______________, because neither A nor B “tags” alarm his immune system.
Universal recipients
People that contain the “identification tag” known as the Rh factor are said to be:
Rh positive
People who lack the “identification tag” known as Rh positive are said to be:
Rh negative
Who was the seventeenth-century Englishman who was the first to describe the circulation of blood accurately, and called the heart “the sovereign of the body”?
William Harvey
The heart is encased within a tough white sac called the __________, which helps support and protect the heart.
Pericardium
Internally, the main features of the heart are its four hollow spaces, or:
Chambers
The pumping mechanism of the heart consists of two ventricles and two thin-walled upper chambers, called:
Atria
The pumping mechanism of the heart consists of two atria and two thick-walled lower chambers called:
Ventricles
A thick vertical wall called the __________ divides the left atrium and left ventricle from the right atrium and right ventricle.
Septum
The walls of the heart’s four chambers can be divided into three layers; the most important is the ___________, which contains the muscles of the heart.
Myocardium
Lining the interior of the heart’s chambers is the _________, which provides a smooth coating for the heart’s interior.
Endocardium
The outside of the heart is with a layer of slippery tissue called the __________, which allows the heart to move easily within the pericardial sac as it beats.
Epicardium
What are the three layers of the heart?
Myocardium
Endocardium
Epicardium
Blood is prevented from flowing in the wrong direction by means of four ______, that are strategically located in the heart.
Valves
Two of the valves of the heart are known as ________ because they allow blood to flow from each atrium into the corresponding ventricle.
A-V valves
What kind of valve of the heart connects the left atrium and left ventricle?
Bicuspid valve
What kind of valve of the heart connects the right atrium and right ventricle?
Tricuspid valve
Two valves of the heart are known as ________ because each of their three cusps is shaped somewhat like the crescent moon.
Semilunar valve
What kind of valve of the heart allows blood to exit the left ventricle and enter the aorta?
Aortic semilunar valve
What kind of valve of the heart allows blood to exit the right ventricle and enter the pulmonary arteries?
Pulmonary semilunar valve
Deoxygenated blood returns to the heart through the __________, which is the body’s largest veins.
Venae cavae
What returns blood from the upper part of the body?
Superior vena cava
What returns blood from the lower part of the body?
Inferior vena cava
What kind of artery transports blood from the heart to the lungs?
Pulmonary artery
What travels back to the heart from the lungs through four pulmonary veins and enters the left atrium and left ventricle, inflating them?
Oxygenated blood
Oxygenated blood travels back to the heart from the lungs through four __________-two for each lung-and enters the left atrium and left ventricle, inflating them.
Pulmonary veins
Blood enters the blood vessels that pass over the surface of the heart and into its interior by means of the two ___________, which branch from the base of the aorta.
Coronary arteries
After supplying the cardiac muscle tissues with fuel and oxygen, blood leaves these tissues through blood vessels known as ___________, which collect the blood from the tissues of the heart and carry it to a larger vein called the coronary sinus, which empties into the right atrium.
Cardiac veins
When an obstruction large enough to block a major branch of a coronary artery, it can block the supply of blood to a large portion of heart muscle; when this occurs, a person is said to have suffered a _______, a type of heart failure caused by a blockage of blood flow to the heart muscles.
Heart attack
