WITH ANSWERS GRADED A+
◍ What are the components of the cardiovascular system?.
Answer: The components of the cardiovascular system include the heart,
blood vessels (arteries, veins, and capillaries), and blood.
◍ Endocrine System.
Answer: regulates functions of the body to maintain homeostasis, and
coordinates communication.
◍ What are the functions of blood?.
Answer: (TTRRD) Blood functions include transportation of oxygen and
nutrients, stabilize body temperature, regulate pH and ion composition of IF,
restrict fluid loss at injury sites (platelets), and defend against toxins and
pathogens
◍ Nonsteroids are composed of _________?.
Answer: Proteins, Parts of Proteins, Amino Acids
◍ What are the important components of blood?.
Answer: Blood consists of plasma and formed elements, which include red
blood cells, white blood cells, and platelets.
◍ Steroids are composed of ___________?.
Answer: Cholesterol
◍ What is hematocrit?.
Answer: Hematocrit is the packed cell volume (PCV) % formed elements.
Over average is 45%.Anemia- low hematocrit, common in
, femalesPolycythemia- high hematocrit, common in males
◍ Which plasma proteins are elevated during an infection?.
Answer: During an infection, WBCs are typically elevated.
◍ What are hemocytoblasts?.
Answer: Hemocytoblasts are stem cells in the bone marrow that give rise to
all types of blood cells. They produce two types of stem cells: lymphoid &
myeloid
◍ What are platelets and their origin?.
Answer: Platelets are small cell fragments derived from megakaryocytes in
the bone marrow and play a crucial role in blood clotting.
◍ What do lymphoid stem cells produce?.
Answer: Lymphoid stem cells produce lymphocytes (type of WBC) ,
including B cells and T cells.
◍ What do myeloid stem cells produce?.
Answer: Myeloid stem cells produce red blood cells, platelets, and other
types of white blood cells except lymphocytes.
◍ What is hematology?.
Answer: Hematology is the study of blood, blood-forming organs, and blood
disorders.
◍ Endocrine Glands.
Answer: •Cells, tissues, and organs that make up the endocrine
system•Ductless; secrete hormones directly into the body fluids•Means
"internal secretion"•Hormones act only on target cells that contain receptors
for them
◍ What is a complete blood count (CBC)?.
Answer: A complete blood count (CBC) is a laboratory test that measures
the levels of different blood components, including red blood cells, white
blood cells, hemoglobin, hematocrit, and platelets.
◍ Exocrine Glands.
