Answer:
Thoracic aorta.
Explanation:
Aneurysm may be defined as outward swelling or bulging weak spot on the walls of the blood vessels. Aneurysm may also initiate the clot formation or the condition of the embolization.
Thoracic aorta aneurysms is mainly responsible for the dyspnea and difficulty in swallowing known as dysphagia. This condition in cerebral vessels is mainly responsible for the headache and in renal arteries can cause flank pain.
Thus, the correct answer is option (D).
"During inhalation, the diaphragm contracts downward, and rib muscles pull upward, causing air to fill the lungs. (This increases the volume of the thoracic cavity and decreases pressure in the lungs — the air will flow from the higher pressure environment to lower pressure area in the lungs.) "
"When you pull down on the diaphragm, you increase the volume of the bell jar, thus lowering the pressure. Air is then forced into the “lungs” from outside, lowering the volume in the bell jar (and stretching the balloons) until the pressures inside and outside the bell jar are equal."
A chromosome is made of a very long strand of DNA and contains many genes (hundreds to thousands). The genes on each chromosome are arranged in a particular sequence, and each gene has a particular location on the chromosome (called its locus).
Answer:
Option (A), (C) and (D).
Explanation:
A mucosa is the membrane that mainly lines the body cavities and covers the internal surface organ of the body. The mucosa is present in the whole intestinal tract.
This mucosa plays an important role in the immunity of the organisms. The mucosa contains both the B cells and T cells that plays an important role in humoral immunity and cell mediated immunity. The neutrophils plays an important role in the inflammation and also phagocytose the cell.
Thus, the correct answer is option (A), (C) and (D).
