2. In an iron-deficiency anemia erythrocytes look ..................................... and are called .....................
3. Pernicious anemia describes the condition of B12 deficiency. In this type of anemia Erythrocytes look ........................ and are called........................
4. Describe the difference between Sickle Cell Anemia and Thalassemia
5. The heart is divided into 2 sides: _______________and_______________
6. Indicate the structure of the respiratory wall.
1.Hemorrhagic anemia is a condition after severe blood loss such as excessive menstrual flow or slow loss of blood from an ulcer or cancer of gastrointestinal tract.
2.In an iron deficiency anemia erythrocytes look in smaller in size,pale and relatively colourless called as hypochromic cells and may also show poikilocytosis that is variation in shape and anisocytosis that is variation in size. This condition is also called as microcytic anemia
3.Pernicious anemia describes the condition of B12 deficiency. In this type of anemia erythrocytes look large, immature and are called as nucleated cell which is said to be megaloblastic anemia condition.
4. Sickle cell disease is a group of disorders that affects haemoglobin, the molecules in RBC that delivers oxygen to cells through out the body
Thalaseemia Is inherited blood disorder characterized by abnormal haemoglobin production
5. The heart is divided into 2 sides that is atria and ventricles. The two upper Chambers are called as atria, the right atrium and left atrium are separated by a wall of tissue called the atrial septum. The two lower chambers are called the ventricles and right ventricules and left ventricules are separated by ventricular septum.
6. The structure of respiratory wall composed of three layers - a.mucosa that covers the luminal surface and consists of pseudostratified ciliated columnar epithelium with mucosous goblet cells and thin lamina propria.
b.fibrocartilaginous layer - supports the walls,being composed of hyaline and elastic cartilages and bundles of smooth muscle tissue
c. Adventitia - loosely connects both previous layers with surroundings and is composed of loose connective tissue with blood vessels and nerve bundles
