What Is The Primary Function Of Blood – Erythrocytes They have biconcave discs Why do they have this shape? Gases increase the diffusible surface area, bringing the cell membrane closer to the hemoglobin inside the RBC.

What is this responsible for? When the color of blood combines with oxygen, it is called … oxyhemoglobin (bright red) When it does not combine with oxygen, it is called … deoxyhemoglobin (dark red)

What Is The Primary Function Of Blood

May become cyanotic when hypoxia (low oxygen level) occurs. Low temperature can cause cyanosis, because it reduces blood flow, what does this mean? Their skin is bluish due to high concentration of deoxyhemoglobin.

Question 511 ptswhat Is The Primary Function Of

120 days (4 months) What does erythropoietin do to the blood? Erythropoietin is a hormone that controls the rate of RBC formation. The kidneys (and liver) release this in response to oxygen deprivation, which produces more RBCs.

Decreases the oxygen carrying capacity of the blood.

Aka Leukocytes What is their main function? What do WBCs grow to protect against disease? Hemocytoblasts in response to hormones

Has granular cytoplasm – About 2x size of RBC – Short life span: about 12 hours – Grows in red bone marrow 1. Neutrophils: % of WBC 2. Eosinophils: 1-3% of WBC 3. Basophils: less than 1% of WBC at

B. Agranulocyte – lack of granules 4. Monocyte: 3-9% of WBC – largest blood cell -2-3x diameter of RBC 5. Lymphocyte: % of WBC – formed in organs of lymphatic system and red bone marrow – slightly larger than RBC

Some kill/phagocytize bacterial cells Produce proteins (antibodies) that destroy foreign particles Neutrophils/monocytes: contain lysosomes; Bacteria Eosinophils: attract and kill certain parasites; Helps control inflammation/allergic reactions Basophils: some contain heparin (prevents blood clotting) and/or histamine (increases blood flow to injured tissue) – helps with allergic reactions Lymphocytes: important for immunity

Greater than 10,000 cells/mm3 = leukocytosis – Acute infection (appendicitis) Decrease: -Less than 5,000 cells/mm3 = Leukopenia – Typhoid fever, influenza, measles, mumps, chicken pox, AIDS, polio

Megakaryocytes – fragments of platelets that are inactive (so they are not actually whole cells) – these develop from hemocytoblasts in response to thrombopoietin.

30 Plasma Proteins Most common solutes in plasma (solutes) Are these used as sources of energy? No

What helps regulate those synthesized in the liver? Osmotic pressure – regulates the movement of water between the blood and tissues, therefore helping to control blood volume and blood pressure

Hemoglobin: Function, Structure, Abnormal Levels

32 Globulins – 3 types account for 36%: Alpha, Beta, Gamma Where are they produced? Alpha and Beta = liver Gamma = lymph tissue What is their primary function? Transport of lipids and fat-soluble vitamins

33 Fibrinogens – Accounts for 4% What is their primary function? Are blood clots the smallest or largest plasma proteins? Largest * See summary note on pg. 539

Amino acids – plasma transports them to the liver where they are used to make proteins Glucose – plasma transports these from the small intestine to the liver where it is stored as glycogen or fat.

36 Lipids – include fats (triglycerides), phospholipids, and cholesterol – combine with proteins to form lipoprotein complexes – consist of phospholipids, cholesterol, and proteins surrounding a triglyceride.

A Clinical Trial To Evaluate The Effect Of Statin Use On Lowering Aldosterone Levels

Low-density lipoprotein (LDL): high concentration of cholesterol – lipoprotein that carries the main cholesterol (bad cholesterol!) High-density lipoprotein (HDL): high concentration of protein – low concentration of lipids (good cholesterol!)

Amino acids Urea Uric acid Give examples of electrolytes in blood plasma: Na, K, Ca, Mg, Cl, Bicarbonate, P, Sulfate ions

What 3 actions help limit/prevent bleeding after an injury to a blood vessel? 1. Vascular spasms 2. Platelet plug formation 3. Blood clots

40 1. Vasospasm Vasospasm: Lasts a few minutes; What is formed at the end of effects vasospasm for 30 minutes? Platelet plugs What hormone does platelets release that causes blood vessels to constrict further? Serotonin

Question Video: Stating The Primary Function Of Platelets In The Body

What do platelets adhere to? (3 things) 1. to any rough surface and to collagen 2. to collagen beneath the lining 3. to each other, forming a platelet plug What type of blood vessel rupture can a platelet plug control? small pauses; A large break requires a blood clot

42 3. What is the most effective hemostatic mechanism of blood clotting? What causes this clotting? What are other names for clotting factors that form a blood clot? Biochemicals

The clear, yellow liquid that remains after clotting is an example of a positive feedback system. Explain this. The original action stimulates the same type of action (freezing) – this way can only work for a short time

45 Thrombus vs. embolus Thrombus: An abnormally formed blood clot in a vessel Embolus: A dislodged blood clot (or fragment) that breaks loose and travels away from the bloodstream.

Iliac Artery (human Anatomy): Image, Functions, Diseases And Treatments

Coronary thrombosis: blood clot in a vessel that supplies the heart Cerebral thrombosis: formation of a blood clot in a vessel that supplies the brain Pulmonary embolism: a blood clot travels up a vessel to the lungs Infarction: when a blood clot destroys tissue (myocardial infarction = heart attack)

A, B, and O What 2 facts is it based on? – based on the presence of two major antigens: antigen A and antigen B

Blood type Antibodies present Antibodies present O O Anti-A, Anti-B A or B Not A, B, AB, O

Rh positive: If none of the Rh antigens are present in RBC membranes, you are Rh+ Rh negative: you lack all Rh antigens.

Blood Function And Composition

First time: no effect; But you have now been sensitized to Rh+ blood for the 2nd time: because you have already been sensitized to Rh+ blood, the donated RBCs may aggregate (clot) (in other words, your body knows how to fight against Rh+ blood and it will fight against)

If the child is Rh+, the 2nd child passes through the mother’s blood at birth: if this child is Rh+, the antibodies can destroy the fetal RBC = erythroblastosis fetalis (hematosis of the newborn).

61 To prevent this… RhoGAM is given within 72 hours of possible exposure (birth, amniocentesis, abortion) to protect Rh+ cells from contacting the mother.

It does many things like carrying oxygen throughout your body to keep your body functioning. Blood cancers and blood disorders can be prevented by doing a vital job for the blood. Health care providers have many ways to treat blood cancers and blood disorders.

Blood is mostly liquid but contains cells and proteins. Blood has four parts: red blood cells (bottom right), white blood cells, platelets (middle right), and plasma (top right).

Blood is vital life force, constantly flowing and keeping your body functioning. Blood is mostly liquid but contains cells and proteins that make it literally thicker than water.

Blood has four components: red blood cells, white blood cells, platelets, and plasma. Each part has specific and important functions, from carrying oxygen to carrying away waste.

Your blood also acts as a health barometer. Abnormal blood test results can be the first sign of changes that can lead to serious illness. This article focuses on how blood works and conditions that affect blood health.

Blood has four parts. Red blood cells and plasma make up most of your blood. White blood cells and platelets, sometimes called the buffy coat, make up less than 1% of your blood.

Red blood cells (erythrocytes) make up 45% of your blood. They carry oxygen throughout your body. They also help eliminate waste from your body. These cells:

Your white blood cells (leukocytes) make up less than 1% of your blood and are part of your immune system. When invaders such as viruses or cancer cells launch an attack, your white blood cells quickly find and work to destroy them. White blood cells can travel from capillaries into your tissues. There are five types of white blood cells:

Whenever your blood vessels are damaged and bleeding occurs, your platelets (thrombocytes) are the first to appear. Platelets manage bleeding by forming blood clots that seal off damaged blood vessels so you don’t lose too much blood. Platelets:

Your blood cells and platelets float in your plasma. Plasma is a yellow fluid that makes up 55% of your blood. Plasma is your blood’s utility player, and it covers a lot of bases as it works to keep your body functioning. Some of the functions of plasma include:

There are four blood types. Types differ depending on whether the blood contains certain antigens. Antigens are substances that your immune system reacts to.
