6 Blood Blood is a type of connective tissue whose cells are suspended in a fluid matrix. Its cells, which are mostly made in the bone marrow, include red blood cells, white blood cells, and platelets. These are built-in elements. The liquid part of blood is called plasma.

An average adult has a blood volume of about 5 liters. Men have more blood than women. Men have 1.5 gallons/women have gallons. Effect of body fat – proportionally.

9 Blood Composition About 45% of blood is made up of elements. This is called hematocrit (HCT). Blood plasma = 55% water 92% protein 7% other solutes 1%

Red Blood Cell

RBCs make up 99.9% of the formed cells. 5.5 million per cubic millimeter in men; 4.8 Anemia in women reduces their number.

The shape is a concave disc. Lacking a nucleus, it therefore lives for only 120 days. Shape is a function that allows for increased surface area through which gases can diffuse. Also allows for better hemoglobin transport.

It has four parts. Each part has an iron-carrying part = heme and a protein part = globin. Fe will carry an oxygen molecule to form iron oxide (rust) and give the blood a red color Oxygen is carried to the cells while carbon dioxide is removed

14 Erythropoiesis All blood cells begin as stem cells in the bone marrow – the hemocytoblast. Controlled through negative feedback by a hormone released from the kidney: erythropoietin. Released in response to lack of oxygen. Why would it be released when O2 is low?

Blood Accept No Substitute.

15 Anemia When the red blood cells cannot carry enough oxygen, it is called anemia. Cannot carry related oxygen.

Hemoglobin is divided into heme and globin components. Heme turns into iron and belverdine – a green color. Often iron and globin are recycled. If not, beliverdin is converted to bilirubin – an orange pigment. Patients with jaundice have inefficient excretion of bilirubin.

Most RBCs overproduce bilirubin. A result of liver or gallbladder failure with ineffective excretion of bilirubin. Here is a Russian man who is a victim of bootleg alcohol containing medical antidotes.

Most leeches are hematophagous but not all can eat. Some survive from decaying matter and already open wounds. The boil produces an anticoagulant, hirudin, which prevents blood clotting and allows the boil to get more blood from the wound. Derivatives of heroin are used in some medicines. Leeches in Medicine video

Most female bees are hematophagous. They drink blood to supplement their protein and iron for the growth of their eggs. Bee saliva inhibits vascular occlusion, blood clotting, platelet aggregation, angiogenesis (growth of new blood vessels), and immunity. They are also vectors of many diseases. Bee video

A.k.a. Most bugs in this family of kissing bugs are hematophagous. Widespread in South America, these insects are vectors for Chagas disease. This disease can damage the heart, nervous system and digestive system. Killer Bug VS Bat Video

WBC protects against disease. Growing from stem cells in response to hormones. has a nucleus No hemoglobin – can’t carry oxygen. 5,000 – 9,000/mm3.

Accounts for more than 50% of leukocytes in adult humans. Getting to the scene of the infection first. Phagocytic – absorbs small particles. Contains lysosomes, organelles that break down organic matter in captured bacteria. Release chemicals to kill bacteria (H2O2, defenses, leukotrienes)

Only 1-3% make up leukocytes. Kills some parasites. Help control inflammation and allergic reactions by removing biochemicals associated with these reactions.

What Is The Primary Function Of The Blood Brain Barrier

Helps to eliminate inflammation. Releases histamine (increases blood flow to injured tissue) and heparin (anti-clotting substance) therefore keeps things fluid.

Protein Structure And Function

Less than 10% make up leukocytes. Live for a few weeks or months. Phagocytic – large bacterial cells go directly to the site and release chemicals to attract more WBC’s to attract fibroblasts which start the repair process (wound tissue).

Leukocytes account for 25-33%. Live for many years (in storage). Most of them are in the lymphatic system. Important in immunity – produces antibodies that attack specific foreign substances. T cells – coordinate the immune response B cells – produce human immunity (antibodies) NK cells (natural killer cells) – respond to tumors and viruses.

1. The most common type of blood cell is A. Leukocyte. b. erythrocyte C. Monocyte. 2. The primary function of red blood cells is A. immunity. B. Blood transfusion. c. Oxygen transport. 3. Eosinophils are a type of white blood cell whose job is to help with allergic reactions. Invasion of tumors. Absorb larger particles.

36 Platelets are immature cells called megakaryocytes from fragmented cells in the bone marrow. Absence of nucleus – lives only 10 days. Platelet count varies from 130,000 – 360,000/mm3. Platelets help break up the blockage in damaged blood vessels and initiate the formation of blood clots.

Visualizing The Composition Of Blood

37 Blood Plasma Plasma – The clear, stone-colored liquid portion of blood in which cells and platelets are suspended. Plasma proteins: albumin – osmotic pressure globulin – transports lipids fibrinogen – helps in clotting

Intercourse – causes blood clots to form. Complex with many steps, many use biochemicals called clotting factors. Results in SCUBA.

Excessive intercourse Inadequate coagulation Embolus – blood clot Thombus – blood clot that attaches to the vessel wall * Also called plaque hemophilia – In an inherited disorder of missing factor VIII, plasma transfusions can restore clotting factors It increases the risk of infection from AIDS and hepatitis B

Early blood transfusions sometimes cause bleeding. Agglutination is the clumping of red blood cells after a transfusion reaction. Antigens are molecules on the surface of red blood cells. known as agglutinin during clumping. Antibodies are proteins that are carried in the plasma. They are called agglutinins when they react during clumping.

41 ABO Blood Group Blood groups depend on the presence or absence of two major protein antigens on the RBC membrane – antigen A and antigen B. Each person has four possible combinations of antigens on the surface of the RBC: A only = blood type (41% of US) only B = type B blood (9% of US) both A and B = type AB blood (3% of US) neither A nor B = type O blood (47% of US %)

42 ABO blood group Some antibodies are produced between 2 and 8 months after birth. This is an inherited trait. If antigen A is not present, an antibody called anti-A is produced. If antigen B is not present, the antibody anti-B is formed. What type of antibodies does A, B, AB and O have in the blood? One type of antibody will react with another type of antigen and clump the RBCs. Which one can be given?

Blood contains several Rh antigens, main = antigen D. If antigen D or any other Rh antigen is present in the blood, the blood is Rh-positive. If the blood lacks antigens
