13 Questions
What are the potential consequences of having high blood pressure?
Too much pressure against vessels can cause them to rupture.
What are the main functions of blood in the body?
To transport nutrients, gases & waste products, transport chemical messengers, maintain constant temperature and blood pressure, and protect against blood loss & pathogens or toxins.
How does anemia affect the body?
Anemia occurs when there aren't enough red blood cells, which can lead to fatigue and weakness.
What could a higher than average white blood cell count indicate?
Leukemia (rapidly reproducing cancerous WBC) or the body fighting off infections.
What are the potential consequences of having low blood pressure?
Not enough blood getting to where you need it; too cold temperature leading to denatured enzymes and decreased functionality.
What are the main functions of blood in the body?
Transporting nutrients, gases, and waste products; transporting hormones; maintaining constant temperature and blood pressure; protecting against blood loss and pathogens or toxins.
What are the components of blood and their respective proportions?
Plasma (fluid portion) - 55%, RBC (erythrocytes) - most abundant cell portion, WBC (leukocytes) & platelets (thrombocytes) - all cell components are 45%.
How does anemia affect the body?
Anemia results in not having enough RBC, leading to decreased oxygen-carrying capacity of the blood.
What does a higher than average white blood cell count indicate?
A higher than average white blood cell count could indicate leukemia (WBC are cancerous) or the body is fighting off infections.
Explain the potential consequences of having high blood pressure on blood vessels.
High blood pressure can lead to too much pressure against vessels, causing them to rupture.
How does maintaining a constant temperature contribute to the proper functioning of enzymes in the body?
Maintaining a constant temperature prevents denaturation of enzymes, ensuring their proper functionality.
What is the significance of the proportion of RBC (erythrocytes) in blood?
RBC are the most abundant cell portion, essential for oxygen transport and overall blood function.
How does blood protect against pathogens or toxins?
Blood protects against pathogens or toxins by defending against blood loss and fighting off pathogens or toxins through the action of white blood cells.
This quiz covers the main functions of the cardiovascular system, including the transport of nutrients, gases, and waste products, the regulation of body temperature and blood pressure, and the protection against blood loss, pathogens, and toxins.
