Answer:
Option c. cause pooling of the blood and decreased venous return to the heart
Explanation:
The ACE inhibitors increases the diameter of the blood vessels (vasodilation) that improves the flow of blood. This reduces the work load on the heart. At the time of heart failure, a substance called angiotensin is released. This angiotensin formation is blocked by the ACE inhibitors. Angiotensin is involved in narrowing the blood vessels.
The ACE cause pooling of the blood and decreased venous return to the heart. The ACE inhibitors causes vasodilation that allows decrease in blood pressure. So, there is no increase in arterial pressure, aldosterone and loss of volume. Thus, option C is correct.
This statement is true. Early land animals indeed had gills as well as lungs. It is generally known that amphibians breathe through their skin, like how the lungs needed the skin for its respiratory. Fish have gills for breathing while mammals do have their nasal cavity and lungs for their gas exchange.
Answer:
Seen on the explanation.
Explanation:
Glandular tissues are a mixture of both endocrine (ductless, hormones are secreted directly into the blood) and exocrine (have ducts, hormones are secreted into surfaces) glands.
The pancreas and salivary glands are both exocrine glands although the pancreas has an endocrine function via the islets of Langerhans, both aid in the digestion of food.
The pancreas lacks striated ducts and the intralobular duct is similar to the intercalated duct of salivary glands. It often has a collapsed lumens and the cells are cuboidal with little cytoplasmic staining in contrast to acinar cells.
The pancreas can also be distinguished from the parotid gland by the presence of the pancreatic islet (islets of langerharns) which has an endocrine function.
