How Is Iron-Deficiency Anemia Diagnosed?

Iron-deficiency anemia is diagnosed by blood tests that should include a complete blood count (CBC). Additional tests may be ordered to evaluate the levels of serum ferritin, iron, total iron-binding capacity, and/or transferrin.

Anemia occurs when your blood doesn't have enough red blood cells. This can happen if: Your body doesn't make enough red blood cells. Bleeding causes you to lose red blood cells more quickly than they can be replaced. Your body destroys red blood cells.

Stages

Stage 1: Diminished total-body iron content. This stage is identified by a reduction in serum ferritin

Stage 2: Reduced red blood cell formation

Stage 3: Iron deficiency anemia.

Tear glands have vesicles that release their secretion by exocytosis. These are classified as ___________ glands. However, _____

Vilka [71]

Answer:

1. Merocrine

2. Holocrine

Explanation:

Merocrine glands are the exocrine glands that synthesize their secretions on ribosomes attached to rough ER. These secretions are packaged by the Golgi complex into the secretory vesicles and are released from the cell via exocytosis. Tear glands, salivary glands are some examples of merocrine glands.

The cells of holocrine glands do not have vesicles but accumulate a secretory product in their cytosol. The mature secretory cells rupture to release the secretory product. This results in the presence of large amounts of lipids from the plasma membrane and intracellular membranes in secretions of these glands. One example of a holocrine gland is an oil-producing gland of the skin.

Birds and mammals have a four-chambered heart, but most reptiles have a three-chambered heart. How does this fact affect the con

eduard

Answer:

The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.

Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.

The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs. The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.

In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.

This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.
