Erythrocytes and Platelets
Two characteristics of red blood cells
What is biconcave shape and anucleate?
Leukocyte involved in the allergic reaction with the release of histamine.
What are basophils?
Universal donor
What is O-negative?
Graph showing the electrical activity of the heart where the normal heart rhythm is represented by a P-QRS Complex-T pattern.
Blood exiting the left ventricle passes through this artery, the largest artery in the body.
What is the aorta?
High blood pressure due to obesity, blockage in the heart, lack of exercise, smoking, etc.
What is hypertension?
Blood protein that carries oxygen
What is hemaglobin?
These blood cells produce antibodies.
What are B-lymphocytes?
The clumping of blood due to a transfusion reaction.
What is agglutination?
When the ventricles are relaxed the heart is in this state.
What is diastole?
When open, this valve allows blood to pass from the left atrium to the left ventricle.
What is the biscuspid or mitral valve?
Blockage of coronary arteries due to the build up of plaque.
What is artherosclerosis?
Percentage of blood volume occupied by erythrocytes
What is the hematocrit?
Leukocyte found during an attack of parasitic worms
What are eosinophils?
This blood type contains no antibodies against A, B, or Rh antigens.
What is AB-positive?
A clot that has broken loose is called this.
What is an embolus?
The inner lining of the heart.
What is the endocardium?
Cell death due to a lack of oxygen in the heart muscle leads to this.
Hormone that initiates the formation of red blood cells
What is erythropoietin?
Leukocyte whose primary job is phagocystosis or being the clean up crew.
What are monocytes?
What is hematopoiesis?
This structure of the heart's electrical system is known as the pacemaker.
What is the sinoatrial node?
These 'strings' connect the papillary muscles to the atrioventricular valves, allowing them to open during the diastolic phase.
What are the chordae tendinae?
Hole in the wall between the atria is called this.
What is an atrial septal defect?
Platelets are part of this process
What is the process of hemostasis or clotting?
Condition caused by the formation of too many malfunctioning leukocytes or white blood cells.
What is leukemia?
Organ where red blood cells are recycled.
What is the spleen?
Middle cavity of the thorax where the heart is located
What is the mediastinum?
Deoygenated blood leaves the right ventricle through these to the lungs.
What are the pulmonary arteries?
Low blood oxygen that results from production of malformed red blood cells.
What is sickle cell anemia?
