Science Blood Quiz

QuestionAnswer
What does the cardiovascular system do? transports materials to and from your cells
What 3 parts make up the cardiovascular system? heart, blood, blood vessels
How much blood does the body contain? 5 liters
What makes up blood? cells, cell parts, and plasma (the fluid part of the blood)
Define red blood cells -most abundant cells in the body --contain hemoglobin which makes cells red and transport oxygen -- Contains Iron (Fe) and oxygen bonds to the Fe --b/c they are flat there is more surface area to carry more O2 --made in bone marrow
What happens if the body does not receive enough iron? Anemia can occur due to the body not being able to carry enough oxygen. Cells will not receive enough oxygen. Reactions in cells will not take place. Glucose will not be broken down fast enough. Leads to fatigue and being tired.
Define White Blood Cells --destroy pathogens- bacteria, viruses, and other microscopic particles that make you sick --some WBC's engulf pathogens and/or body cells that are dead or damaged --some WBC's release anti bodies which destroy pathogens
What's the difference between antibodies and antibiotics? antibodies- produced by body; antibiotics- produced in lab
What do WBC's contain? WBC's contain more lysosomes b/c they are responsible to attacking and destroying foreign particles. Lysosomes contain digestive enzymes
Platelets --only live 5-10 days --clump together when there is a cut so less blood is lost
Antigens chemicals on surface of RBC
Antibodies chemicals in plasma that bind to antigens not found on their RBC's
Types of blood A, B, AB, O
List antigens and antibodies of type A blood has A antigens and B antibodies
List antigens and antibodies of type B blood has B antigens and A antibodies
List antigens and antibodies of type AB blood has AB antigens and no antibodies
List antigens and antibodies of type O blood has no antigens and AB antibodies
Universal donor type O b/c its RBC's do not have antigens so recipients' blood will not attack it
Universal recipient type AB b/c they do not produce antibodies against any antigens on the donor's blood cells
Define blood vessels hollow tubes that transports blood
What are 2 characteristics of arteries? --directs blood away from the heart to the body --thick walls
Explain the relationship between structure and function for arteries. The thick walls of the arteries puts more force and pressure on the blood which allows the blood to disperse all over the body, and back to the heart because it continues doing all the work/pushing and it's a cycle.
What are 2 characteristics of capillaries? --Smallest blood vessels in the body --Cells must pass through one at a time
Veins direct blood back into the heart
Define blood pressure force exerted by blood on the inside walls of a blood vessel
What is a normal blood pressure? 120/80
Define systolic and diastolic pressure. systolic- inside large arteries when ventricles contract diastolic- inside arteries when ventricles relax
Define the heart self-excitory muscle- it can initiate contraction without receiving signals from the brain
What does the job of the heart and what size is it? --pumps oxygen poor blood to the lungs and oxygen rich blood to the body --size of your fist
