Answer:
b. Osteoblasts
Explanation:
Osteoblasts are responsible for secreting the extacellumar matrix components responsible bone formation. Osteocytes are matured osteoblasts.
During inspiration, a diameter decrease of the inferior vena cava (IVC) of 50% or more has been seen as a marker of normal central venous pressure.
<h3>What is the vena cava? </h3>
Large veins that convey deoxygenated blood to your heart so it may receive oxygen are called the superior vena cava and inferior vena cava. The biggest vein in your body, the inferior vena cava, returns oxygen-depleted blood from the lower half of your body to your heart (below your diaphragm).
Your heart receives oxygen-poor blood from your upper body through your superior vena cava, your second-largest vein. The vital job of the superior and inferior vena cava is to transport oxygen-poor blood to the right atrium of the heart, where it passes into the right ventricle and then travels to the lungs (through the pulmonary artery) to exchange carbon dioxide for oxygen.
Blood that has been oxygenated returns to the left atrium of your heart via your pulmonary veins. Blood that is now carrying brand-new oxygen then travels to your left ventricle and aorta before being distributed throughout your body.
Therefore, a diameter decrease of the inferior vena cava (IVC) of 50% or more is a marker of normal central venous pressure.

Answer:
A, leukemia
Explanation:
Cancer of white blood cells is called leukemia. White blood cells are very important in the body as they fight infections. When a person has leukemia, his bone marrow produces abnormal white blood cells which don't function properly.
It is a form of blood cancer that starts in the bone marrow. Symptoms of this disease may include bleeding and bruising, feeling tired and being at higher risk for infections. The diagnosis is made during a blood test or a bone marrow biopsy.
Answer:
The best answer to the question, would be: In terms of nearness to the trunk, the antebrachium is proximal to the carpal region.
Explanation:
In anatomy, we use certain terminology to be able to express where different anatomical parts of the body are positioned and located, related to others. Just like through the axes that are used to divide our bodies into sections, and these lines help us to determine exactly where a body part, organ, or region, is located in reference to others, we can also use central regions, like the trunk of the body, to mention the location of other parts in relation to it, and to others. The carpal and antebrachium regions are parts of the arms, and both, relative to the trunk, are distal, which means, far from it. But, when taking the trunk as reference, we talk about the location of these two parts in relation to one another, and the trunk we say that both are proximal to one another because they both are closer to each other than either one is to the trunk itself.
