The Bloody Flashcards
What are the functions of Neutrophil
- Defend body against bacterial invasion
- Engulf and digest bacteria (process called phagocytosis)
Release of antimicrobial chemicals
What are the functions of Eosinophil
-Inflammatory response
-Phagocytosis
What are the functions of Basophil
- Inflammatory response through release of histamine
- Release heparin to reduce formation of tiny blood clots
What are the functions of Lymphoctye
-T Cells: Cellular Immunity: Secrete cytotoxic substances that kills the foreign cells
-B Cells: Humoral Immunity: Produce antibodies and immunoglobulin
What are the functions of Monocyte
-Inflammatory response
-Phagocytosis
-Synthesize and release cytokines
Type of blood transferred in the arteries
Oxyhaemoglobin
Type of blood transferred in the veins
Deoxyhaemoglobin
Movement of blood coming from arteries
Away from heat to body tissues
Movement of blood coming from veins
From body tissues to heart
Why is transportation of blood needed
Transport substances to and away from the body cells (Oxygen, nutrients, Waste products and carbon dioxide away from the body cells to be excreted)
How does blood help in protecting the body
-Protect body against infection & disease by circulating antibodies and defensive cells
-Prevent excessive blood loss by producing clots
Why is regulation of blood needed in the body
To Regulate water content, body temperature, blood pH and hormones and other chemicals that control the functioning of organs and systems
3 main parts of the blood
-Plasma (water, proteins, mineral salts, nutrients, waste products, gases, hormones, antibodies, enzymes)
-Blood cells (Erythrocytes, Leukocytes)
-Cell fragments (Thrombocytes)
What is the 9 things in plasma
-Water
-Proteins
-Mineral salts
-Nutrients
-Waste products
-Gases
-Hormones
-Antibodies
-Enzymes
What is produced in the red bone marrow
Erythrocytes, Leukocytes and Thrombocyte
