The function of the valves in the peripheral veins is to ensure that the overall movement of blood in the veins is in the right direction, toward the heart. This is especially important in the legs, where the blood must flow a relatively long distance against gravity.

Which process occurs in the structures that are labeled X?

Over [174]

According to a source, mitosis.

Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer).

While you are inserting an oropharyngeal airway into a patient's mouth, he begins to gag and then vomit. how should you respond?

den301095 [7]

Hello! If this takes place, then the EMT probably did not use the correct method. They should tilt the head while keeping the chin up. This prevents them from being able to gag. You would not want to change the oxygen flow because that one was probably correct for their situation. So just remove the air supply and follow the head tilt-chin lift procedure.

I hope this helped!

I am, yours most sincerely,

Small intestine can be best described as...

QveST [7]

The answer to this is C.

In the small intestine, it consists of duodenum and ileum in simple. The duodenum is where most food is digested. Enzymes are secreted and they break down complex and insoluble food into simple small soluble molecules.
After digestion, the food will be absorbed into the body in the ileum. The food flow from the ileum into the body cells by diffusion and active transport. Villi is also present in the small intestine to help the absorption process. After absorption, the nutrients would be transferred into the cells that needed.
The rest of the food that is not absorbed is trasferred to the large intestine to re absorb the water. After that, they're feaces and they'll be egested

Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other

Sholpan [36]

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.

<h3>What is plasma?</h3>

It is an aqueous solution that is thick in consistency, straw-colored, and somewhat alkaline. Fifty five percent of the blood is formed by it.

It is made up of a variety of organic and inorganic components, including 90–92% water and 6–8% solutes.

It includes fibrinogen, globulins, albumins, a trace quantity of sodium, calcium, magnesium, chloride, bicarbonate, glucose, amino acids, lipids, and other coagulation-related substances.

Plasma's primary function is to transport proteins, hormones, and nutrients to the body's many organs. Additionally, plasma is where cells dump their waste. The plasma then aids in the body's elimination of this waste. All components of the blood are also transported through your circulatory system by blood plasma.
