Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
Answer:
The healthful benefit of one area affects positive outcomes in the others, and gaps or challenges in one area negatively affect outcomes in the others.

Answer: caring for a person with alzheimer's can affect family in all kinds of ways
Explanation: financially alzheimer's affects a family member by then paying for the treatments for the person with alzheimer's and may have to stop working in order to care for that person . phsically it could be a lot of work to deal with an alzheimer's patient alone without help .

Answer:
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
Answer:
Sarcoplasmic reticulum.`
Explanation:
Muscle fibers are formed by the process of myogenesis in humans. These fibers help in the contraction of the muscle and also helps in the body movement.
Sarcoplasmic reticulum is a cell organelle present in the muscle fibers that corresponds to the structure of endoplamsic reticulum. Sarcoplasmic reticulum stores the calcium ions in the muscle fibers.
Thus, the answer is sarcoplasmic reticulum.
