How does the cardiovascular system deliver nutrients and oxygen to all cells in the body via the flow of blood? Select all corre

ct answers.
(The arteries carry blood away from the heart; the veins carry it back to the heart.)

(In the systemic circulation, the left ventricle pumps oxygen-rich blood into the aorta.)

(Veins contain a series of one-way valves that close to prevent the back flow of circulating blood.)

(Blood, which is low in oxygen, is collected in veins and travels to the right atrium and into the right ventricle.)

(The left ventricle pumps low-oxygen blood into the pulmonary artery, which branches off into smaller and smaller arteries and capillaries.)

(Carbon dioxide is released from the blood into the air via capillaries surrounding the heart.)

Answer:

1: (The arteries carry blood away from the heart; the veins carry it back to the heart.)

2: (In the systemic circulation, the left ventricle pumps oxygen-rich blood into the aorta.)

4: (Blood, which is low in oxygen, is collected in veins and travels to the right atrium and into the right ventricle.)

Explanation:

The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. ... In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta).

The arteries carry blood away from the heart; the veins carry it back to the heart. ... The blood travels from the main artery to larger and smaller arteries and into the capillary network. There the blood drops off oxygen, nutrients and other important substances and picks up carbon dioxide and waste products.

The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.

the rapid depolarization phase of the action potentials of myocardial contractile cells is due to which ion(s)?
Oduvanchick [21]

The rapid depolarization phase of the action potentials of myocardial contractile cells is due to Na⁺ ion.

The depolarization is caused when Na⁺ ions rapidly enters into neuron through open sodium channels. Sodium ions plays important role in various physiological process such as regulating blood volume, ph regulation,  maintaining blood pressure, energy metabolism,osmotic equilibrium, excitation-contraction coupling, maintenance of cellular homeostasis, development and growth.

In the skeletal muscle cells of vertebrates, as many as ____________ molecules of atp are produced from one molecule of glucose.
shusha [124]
<span>In the skeletal muscle cells of vertebrates, as many as 38 molecules of ATP are produced from one molecule of glucose. This is less than might be expected, because electrons from NADH produced during glycolysis must be shuttled through the inner mitochondrial membrane at a cost.
</span>The energy of the electrons can be used to make ATP and in eukaryotes, glycolysis occurs in the <span>cytosol, outside mitochondria. </span>
