Carries throughout the body: respiratory gases, nutrients, waste, hormones, cells of the immune system and helps body regulate temperature.
Each RBC contains how many hemoglobins?
What is the functions of Leukocytes?
~280 million
Protects the body from infectious microorganisms.
What cells are the true/not true? Elaborate why they are true/not true.
True: Leukocytes
Not True:
-Platelets(Thrombocytes): They are cell fragments
-RBC(Erythrocytes): They lack nuclei and organelles
What is the process of circulating leukocytes leaving the capillaries.
What are the two types of leukocyte?
Diapedesis
Granulocytes and Agranulocytes
What functions in clotting?

The average volume of blood in the body is about ______ in adult males and ______ in adult females
5-6 Liters, 4-5 Liters
True or False there is fibers in blood.
True or False the special characteristics of red blood cells are 98% hemoglobin, biconcave shape, aerobic energy generation
False There is no fibers but their is fibrin threads.
False 97% hemoglobin, biconcave shape, anaerobic energy generation
What are your granulocytes and agranulocytes?
List the Leukocytes from most abundant to least abundant.
Granulocytes: Neutrophils, Eosinophils, and Basophils.
Agranulocytes: Lymphocytes and Monocytes.
Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils.
What are the 2 components of blood?
Plasma and Formed Elements
The Circulatory system is divided into the __________ and the __________.
Cardiovascular system, Lymphatic System
What are the two main classes of lymphocytes?
T-Cells and B-Cells
Diameter of oxygen-transporting cells (erythrocytes).
Life span of erythrocytes, which originate in bone marrow.
7.5 μm
100-120 Days
Mature RBCs have no organelles or nuclei...Instead their cytoplasm is filled with ______________ an oxygen-carrying protein
Hemoglobin
True or False blood is classified as a connective tissue.
What is the alternate name for RBC, WBC, and Platelets?
True
Erythrocytes, Leukocytes, and Thrombocytes
What is the fluid in the vessels of the cardiovascular system... it transports everything that must be carried from one place to another in the body?
What is powered by the pumping action of the heart?
Blood
Blood Circulation
What contributes to plasma osmotic pressure, which helps keep water from diffusion out of the blood-stream into the extracellular matrix of tissues
What includes both antibodies and blood proteins that transport lipids, iron, and copper.
Albumin
Globulin
What is the difference between myeloid and lymphoid stem cells?
Lymphoid: give rise to lymphocytes
Myeloid: gives rise to all other stem cells
Living cells (erythrocytes, leukocytes, &thrombocytes) suspended in the plasma.
What is the process by which blood cells are formed; begins in the early embryo and continues throughout life?
Hematopoesis.
Erythrocytes pick up oxygen at the _________________ and release it across other tissue capillaries throughout the body.
Lung Capillaries
What attacks foreign eukaryotic cells directly; bind to antigen-bearing cells and punch holes in its membrane...which triggers apoptosis?
What multiplies to become plasma cells that secrete antibodies (proteins that mark specific antigens for destruction by macrophages); mostly attack bacteria and bacterial toxins?
T cells (killer T-lymphocytes)
B Cells
What does the Buffy Coat contain?
What is Hematocrit?
It contains Leukocytes and Platelets.
The percentage of the blood volume that consists of erythrocytes.
True or False Erythrocytes are more common than Leukocytes.
True or False Leukocytes function outside the bloodstream in the loose C.T. where infections occur.
True
True
What are the three types of formed elements present in blood?
Red blood cells (erythrocytes), white blood cells (leukocytes), platelets (thrombocytes)
Give me the percentages of abundance for the leukocytes as well as their functions.
Neutrophils: 60%
Phagocytize and destroy bacteria; first line of defense in an inflammatory response.
Lymphocytes: 20-45%
Effective in fighting infectious organisms; act against a specific foreign molecule (antigen
Monocytes:4-8%
Transform into macrophages... phagocytic cells that possess
pseudopods and ingest a wide variety of foreign cells, molecules, and tiny pieces of debris
Eosinophils: 1-4%
Play roles in ending 1) allergic reactions by phagocytosing allergens and 2) parasitic infections by releasing parasite-digesting enzymes, esp. in the digestive system
Basophils: 0.5%
Granules secrete histamines (function in mediating inflammation) during allergic responses and parasitic infections
