Biology Chapter 11 Blood
spleen lymph nodes thymus gland
lymphatic tissue is found in lymphatic organs such as the
nutrients and waste products
name two types of substances that are transported in dissolved form in plasma
platelets also called thrombocytes
produced in the red bone marrow
pH
slightly alkaline. The normal pH range of blood is 7.35 to 7.45. venous blood usually lower because of CO2
mitosis
stem cells constantly undergo this process to produce new cells
globulins
synthesized by lymphocytes or by the liver include antibodies include carrier molecules for fats in the blood
clotting factors
synthesized only by liver include fibrinogen and prothrombin help prevent blood loss when blood vessels rupture
albumin
synthesized only by the liver pulls tissue fluid into capillaries to maintain blood volume the most abundant plasma protection
biconcave disks
the appearance of RBCs
52% to 62%
the blood plasma make up what percent of the total blood?
hemostasis (prevention of blood loss)
the function of platelets is
120 days
the life span of RBCs
oxygen
the major regulating factor for RBC production is the amount of _________________in the blood and tissues.
calcium
the mineral necessary for chemical clotting is
7.35 to 7.45 alkaline
the normal pH range of blood is pH range is slightly?
protein iron
the nutrients needed for RBC formation include _____________ and ______________which will become part of the hemoglobin molecule
iron
the oxygen-carrying mineral in hemoglobin is
hemoglobin
the oxygen-carrying protein in RBCs is
blood cells and plasma proteins
the presence of these make blood more viscous than water
5,000 to 10,000 cells/uL
the range of WBC count is
150,000 to 300,000 cells/uL
the range of normal platelet count is
reticulocyte
the stage in which fragments of the ER are present is called
lymphocytes
the stem cells of lymphatic tissue produce the WBCs called
embolism
the term for a clot that dislodges and travels to another vessel is
thrombus
the term for an abnormal clot in an intact vessel is
thrombocytopenia
the term for low platelet count is
viscosity
the thickness or resistance to flow. 3-5 times thicker than water. The thickness contributes to normal blood pressure.
vascular spasm patelet plugs chemical clotting
the three mechanism of hemostasis are?
dissolved
the water of plasma is a solvent, which means that substances may ___________________ in this water and be transported
hypoxia
this term means lack of oxygen
hypoxemia
this term means low blood oxygen level
RBCs WBCs Platelets
what are three types of blood cells?
embolus
what is the term for a moving clot?
thrombus
what is the term for a stationary clot?
nucleus
what major cellular structure do mature RBCs lack?
erythroprotein
when hypoxia occurs, the kidneys produce a hormone called
Blood types
Blood type is inherited. -Types are A,B,AB or O. -The letters represent antigens on the red blood cell membrane. O has neither antigen. Rh factor: is another antigen in RBC's. People with an Rh antigen are Rh +. Without are Rh-
transportation regulation protection
General functions of blood are?
transportation
Nutrients and waste products gases and harmones
thrombocytes red bone marrow
Platelets are also called? They formed from?
megakaryocytes and thrombopoietin
Platelets are fragments of the large bone marrow cells called?
oxyhemoglobin
RBCs pick up oxygen when they circulate through the pulmonary capillaries in the lungs, and this hemoglobin is now called
reduced hemoglobin
RBCs release oxygen in systemic capillaries, and their hemoglobin is then called
hemopoietic tissue
Red blood cells are produced from stem cells in __________________________ (marrow) in bones like the sternum, hip and vertebrae
red bone marrow, flat and irregular
after birth, the primary hemopoietic tissue is __________________which is found in _______________, and _________________
RBC
also called erythrocytes. Hematocrit is a measurement of the amount of RBC's. Normal range is 38%- 48%. Both hematocrit and RBC's are part of a complete blood count (CBC).
4 to 6 liters. cells (also called formed elements) and plasma. The liquid part (range of 52% - 62%)
amount of blood in humans
gamma globulins
are antibodies that aid in immunity
WBCs also called luekocytes
are made in Lymphatic tissue like the spleen, thymus, lymph nodes.
albumin
helps maintain normal BP & volume
normoblast
in RBC formation, the last stage with a nucleus is called a
plasma protein
in blood are synthesized by the liver
yolk sac
in the embryo, RBCs are first produced by an external membrane called the
stem cell
in the red bone marrow, the precursor cell for blood cells is called a
plasma
liquid part of blood. ~ 91% water The water of plasma transports: glucose, amino acids & minerals
against pathogens providing WBC's clotting to prevent loss.
Blood protects?
nutrients waste products gases hormones.
Blood transports?
regulation
acid base balance body temperature fluid-electrolyte balance
alpha and beta globulins
acts as carriers for molecules such as fats
protection
blood clotting destroys pathogens
fluid-electrolyte balance acid-base balance body temperature.
blood regulates?
hemopoietic
a tissue in which blood cells are formed
liver spleen
before the red bone marrow takes over completely, two other fetal organs contribute to RBC productions
38% to 48%
blood cells make up what percent of the total blood?
bicarbonate
carbon dioxide is carried in the plasma in the form of
RBCs
carry oxygen
arterial blood is bright red due lots of O2 venous blood has lost O2 and looks dull red.
color of blood
Platelets
destroy pathogens and provide immunity
WBCs
destroy pathogens and provide immunity
