Which white blood cells are known as "bacteria slayers"?
Neutrophils
Which blood vessels carry blood away from the heart?
Arteries
The ______ and ______ are the biggest veins in the body and carry blood to the right atrium
The muscle layer of the heart wall. Located between the most superficial layer and the innermost layer of the heart wall.
Myocardium
The heart chamber between the superior/inferior vena cavae and the tricuspid valve
Right atrium
Which white blood cells are the parasite slayers?
Eosinophils
The lower, more pointed end of the heart
Apex
The pulmonary trunk & left and right pulmonary arteries carry blood from the right ventricle to the ______
lungs
The innermost layer of the heart wall. The inner lining of the chambers. Touch the wall inside any chamber and you are touching this.
Endocardium
The valve between the right ventricle and the pulmonary trunk
Pulmonary valve
What is the life span of a red blood cell?
100 to 120 days
The tough, thick, superficial layer of the pericardial sac
Fibrous pericardium
The first vessel branching off of the aortic arch. It carries blood to the right side of the neck and head as well as to the right shoulder and arm.
Brachiocephalic artery
This valve prevents blood from flowing from the right ventricle back to the right atrium.
Tricuspid valve
The pulmonary ______ carry blood from the lungs to the left atrium.
veins
What is a normal white blood cell count? (range)
4,000 to 11,000 mm3
The layer attached directly to the surface of the heart
Visceral pericardium (epicardium)
The second vessel branching off the aortic arch. It supplies blood to the left side of the neck and head.
Left common carotid artery
When you hear of someone having heart valve problems, it is usually this valve.
Mitral (bicuspid) valve
This valve is located between the left atrium and the left ventricle.
Mitral (bicuspid) valve
Which WBC directly attacks virus-infected cells and tumor cells?
T lymphocytes
A surface groove on the anterior side of the heart filled with coronary vessels and fat. Directly behind this, internally, is a septum by the same name.
Interventricular sulcus
The third branch off of the aortic arch. It supplies blood to the left shoulder and arm.
Left subclavian artery
These muscles contract when the atria contract, and prevent the valves from prolapsing into the ventricle.
Papillary muscles
The largest artery in the body that carries blood from the heart out to the body.
Aorta
