The ABO blood groups are based on which of two antigens, type A or type B, a person inherits; absence of both antigens results in type O blood, presence of both antigens leads to type AB, and the presence of either A or B antigen yields type A or B blood.
Oxygen enters blood in the lungs and is transported to cells. Leukocytes Although leukocytes, or white blood cells, are far less numerous than red blood cells, they are crucial to body defense against disease.
Formed Elements If you observe a stained Blood quiz study guide of human blood under a light microscope, you will see disc-shaped red blood cells, a variety of gaudily stained spherical white blood cells, and some scattered platelets that look like debris.
CO binds with what in the blood? How can it affect a pregnancy?
What is plasma and what is it composed of? In addition, WBCs can locate areas of tissue damage and infection in the body by responding to certain chemicals that diffuse from the damaged cells; this capability is called positive chemotaxis. Eosinophils have blue red nucleus that resembles an old-fashioned telephone receiver and sport coarse, lysosome-like, brick-red cytoplasmic granules; their number increases rapidly during allergies and infections by parasitic worms or entering via the skin.
What does a blood sample look like if someone has leukemia? Control of RBC production. Hematopoiesis Blood cell formation, or hematopoiesis, occurs in red bone marrow, or myeloid tissue.
How is it inherited genetics? Human Blood Groups Although whole blood transfusions can save lives, people have different blood groups, and transfusing incompatible or mismatched blood can be fatal.
What is sickle cell anemia? How is it diagnosed and treated? Blood Groups and Transfusions As we have seen, blood is vital for transporting substances through the body; when blood is lost, the blood vessels constrict and the bone marrow steps up blood cell formation in an attempt to keep the circulation going.
Describe how antibodies and antigens work? What is the most common type? Monocytes are the largest of the WBCs; when they migrate into the tissues, they transform into macrophages with huge appetites; macrophages are very important in fighting chronic infections.
Lymphocytes have a large, dark purple nucleus that occupies most of the cell volume; they tend to take up residence in lymphatic tissues, where they play an important role in the immune response. Plasma proteins are the most abundant solutes in plasma; except for antibodies and protein-based hormones, most plasma proteins are made by the liver.
Components of Blood Essentially, blood is a complex connective tissue in which living blood cells, the formed elements, are suspended. Unlike the antibodies of the ABO system, anti-Rh antibodies are not automatically formed and present in the blood of Rh- Rh-negative individuals.
The hormone thrombopoeitin accelerates the production of platelets, but little is known about how that process is regulated.
Blood is heavier than water and about five times thicker, or more viscous, largely because of its formed elements. RBCs differ from other blood cells because they are anucleate, that is, they lack a nucleus; they also contain a very few organelles.
Depending on the amount of oxygen it is carrying, the color of blood varies from scarlet oxygen-rich to a dull red oxygen-poor.
Where does this occur in adults? All the formed elements arise from a common type of stem cell, the hematocystoblast.
These colony stimulating factors and interleukins not only prompt red bone marrow to turn out leukocytes, but also marshal up an army of WBCs to ward off attacks by enhancing the ability of mature leukocytes to protect the body. Warm blood is transported from the inside to the surface of the body, where heat is released from the blood.A B; blood: connective tissue made of plasma and formed elements: physical characteristics of blood: sticky and opaque with a salty, metallic taste: pH of blood.

This quiz is designed to show how much students of Anatomy and physology (part two) know about Chapter 16, the Blood. Blood is the “river of life” that surges within us. It transports everything that must be carried from one place to another within the body- nutrients, wastes (headed for elimination from the body) and body heat through blood vessels.
