<span>The major structure that supplies the cells with nutrients and removes their waste is the circulatory system. The circulatory system is composed of the heart, the blood vessels going from and back to the heart, and the blood that travels inside them. The blood vessels that carry nutrient and oxygen-rich blood to the cells are arteries. They become the thinner arterioles, and then the thinnest capillaries. With the exception of the pulmonary arteries, which carry non-oxygenated blood from the heart to the lungs, all arteries carry oxygenated blood. The capillaries disburse the nutrients and oxygen to the cells and pick up wastes and carbon dioxide, form into the thicker venules, then to form veins, which lead back to the heart (with the exception of the pulmonary veins, which carry oxygenated blood from the lungs to the heart). Veins also differ from arteries in that veins have valves to prevent blood from flowing backward.</span>
Answer:
The metabolic rate per gram of tissue is greater in large endotherms than in small endotherms.
Explanation:
Metabolic rate is a measurement of metabolism in animals: how much energy is used per time. Energy used on a daily level is described as basal metabolic rate. Among both, endotherms (maintain their own heat) and ectoterms (depend on external heat) metabolic rate depends on animal's activity, active animals have higher metabolic rate.
Metabolic rate in ectoterms vary with temperature, while in endoterms it does not.
A cladogram containing a zebra, bear, lion, and tiger, should look like this:
mammalia
I I
carnivora perissodactyla
I I I
arctoidea feliformia equidae
I I I
ursidae felidae equini
I I I
ursus pantherinae equus
I
panthera
I I
panthera tigris panthera leo
All four animals are part of the mammals, thus it is the closest relation they all have. Further, the lion, tiger, and bear are part of the carnivores, while the zebra is part of herbivores, thus purring the first three to be more closely connected. The bear than diverges into its own family, while the lion and tiger remain in the same, thus making them the most closely related. So we have the lion and tiger to be the closest, than comes the bear, being closer to them then to the zebra, and then comes the zebra which is connected with the other three much further back in the past.
Acute myocardial infarction, digoxin is contraindicated in patients with ventricular fibrillation or in patients with a known hypersensitivity to digoxin.
Digoxin is a type of therapy which has no effect on mortality in heart failure .It is useful for maintaining clinical stability and exercise capability in patients with symptomatic heart failure. DIgoxin is helpful during severe heart failure , cardiomegaly and third heart sound .
Digoxin can't be useful if the pateint have ventricular fibrillation, it is ab arrhythmia that starts from ventricle is called ventricular fibrillation. Digoxin is also called as digitalis , helps in injured or weekend heart pump more efficiently and strengthen the force of heart muscles contractions , helps restore a normal , steady heart rhythm, and improve blood circulation.
