Answer: The correct answer to the question is option D
ISCHEMIC HEART DISEASE.
Explanation: To answer the question effectively, let us look at the options given,what they are and how they affect the heart.
Endothelial cells play a crucial role in the regulating vascular tone,They do so by secreting variable amounts of constricting and relaxing factors inorder to control tissue perfusion.
Hypertension on the other hand occurs as a result of factors that varies distinctively and not all related to vascular tone.
Dysrhythmias on it's own will affect the function and conduction of heart chambers but not necessarily vascular tones.
Truncus arteriosus results in only in one large artery exiting/leaving the heart.
1. Organelles-. e.g. mitochondria, nucleus.
2. Cells- e.g. epithelial cells, palisade cells.
3. Tissues- e.g. muscles, connective tissue.
4. Organs- e.g. heart, liver.
5. Organ systems- e.g. digestive system, circulatory system
This is because there are many organelles inside a cell and a collection of same cells that creates tissues, a collection of tissues form organs, to carry out a particular function, and a collection of organs working together is an organ system. I think this is what they're after as I had a similar question a little while ago.
A is what the human body treats school as
I think that its A. acquiring energy
